Introduction
Modulevel pneumatic controls are displacement actuated
level sensors that provide output signals in direct proportion to changes in liquid level.
Simple modular design and proven magnetic coupling
make Modulevel controls versatile, highly stable, vibration
resistant and adaptable to extremes of temperature and
pressure.

The key elements of the Modulevel
pneumatic control are the magnetic
coupling, which allows the controller
to be mechanically isolated from the
sealed sensing unit; the range spring,
which converts the change in buoyancy
force on the displacer into motion; and
the controller head, which provides a
modulated pneumatic signal in direct
proportion to the motion of the spring.

1.2
Operating Cycle
The result of liquid level changes in
the vessel is a change in the buoyancy
force acting on the displacer and in the
load on the spring from which the displacer is suspended. As the spring
extends or compresses with the change
in load, an attraction ball attached to
the spring via a stem assembly moves
within the enclosing tube.
A magnet encircling the enclosing
tube follows the attraction ball, transferring the motion to a rotating cam,
which in turn operates a flapper
against a nozzle which increases or
decreases the pressure within the pneumatic relay. The output pressure signal
can be used in a variety of ways to
operate a control valve or signal
alarms, indicators, process controls or
other devices.

Description
Modulevel pneumatic instruments are available for a
variety of functions to handle different application
requirements.
1.3.1 Controller Action
1.3.1.1 Proportional Control
Proportional control instruments are used to maintain
the level in a tank within a predetermined band. The
output from the Modulevel head controls the opening
and closing of a valve to control the increase or
decrease of the liquid flow through the vessel.
1.3.1.2 Transmitter
Transmitters provide a pneumatic signal proportional
to the level of a liquid. The signal can be fed to a
variety of devices as the application requires.
1.3.1.3 Transmitter/Receiver Controller
There are two devices in this version. The transmitter
senses level directly at the vessel, and provides a pneumatic signal to the receiver/controller. The receiver/
controller operates in the same manner as a direct
connected level device, such as a proportional controller, which allows varying the proportional band
and level set point. This unit may be mounted either
integrally with the transmitter, or at a more
convenient remote location.
1.3.1.4 Proportional Plus Integral Control
Proportional plus integral control instruments (i.e.,
with reset) operate in the same manner as the proportional unit with one major difference. The offset
between the desired level and the actual level is eliminated, thus maintaining the level at a point rather
than within a band.
6
48-620 Modulevel Pneumatic Liquid Level Control
1.3.1.5 Differential Gap
A differential gap instrument provides two distinct outputs,
either opened or closed. One distinct output value is
obtained when the level exceeds the upper switching point.
This value remains constant until the level decreases below
the lower switching point. At this time the controller
changes to another distinct output value. The new value
remains constant until the level again rises above the upper
switching point causing the output value to return to the
first output value. The distance between the two switching
points is called the differential gap.
1.3.2 Controller Options
Locking
Screw
1.3.2.1 Direct or Reverse Action
Direct acting controllers provide an output signal that
increases with level increase. Reverse acting controllers
provide an output signal that decreases with level increase.
1.3.2.2 Electric Limit Switches
Electric limit switches allow high and low level alarms to be
added to any of the pneumatic instruments described above.
1.3.3 Mounting Arrangements
Figure 2
Top Mount
1.3.3.1 Flanged Top P51, P61 and P62 Displacer Models
When mounting inside the tank is possible, flanged top
models are the answer (Figure 2). They are used extensively
in interface control applications where nonstandard displacers become necessary. An adjustable stainless steel displacer
hanger cable is also available. Top mounting models are
directly interchangeable with the external cage models.
1.3.3.2 Top Mounted APM-131

When mounting inside the tank is possible, threaded
top models are the answer. An adjustable stainless steel
displacer suspension cable is provided as standard.

48-620 Modulevel Pneumatic Liquid Level Control
External cage models (Figure 3) can be easily isolated from
the process to simplify maintenance and inspection
operations. The in-line design eliminates the need for
specifying "right hand" or "left hand". Any mounting
position is possible by rotating the instrument head. A
variety of models are available including sealed or flanged
cage with either side/side or side/bottom connections.
Carbon steel and stainless steel models are available.

Water Column external cage models (Figure 4) can be
easily isolated from the process to simplify maintenance
and inspection operations. Sight glass and Try-cock
tappings are provided.
1.3.3.5 Side Mounted P68 Float Model
Side mounted models (Figure 5) are ideally suited for
narrow level range applications. Carbon steel models are
available with either a 3" NPT threaded body or a 4"
flanged connection.

2.1
Unpacking
After unpacking, inspect all the components to see that no
damage has occurred during shipment. Care should be taken
not to bend the displacer stem or enclosing tube during
unpacking or installation.
Next, open controller case and remove magnet hold down and
nozzle lever retainers. Examine internal controller components
for any obvious damage or loosened parts. Check all air connections to make certain they are free of any foreign matter.
2.1.1 P51, P61, P62 and APM 131 Models
Top mounting Modulevel units are shipped from the factory
with the controller and displacer removed from the head
assembly and packed separately in the same carton or crate.
2.1.2 P53, P55, P63, P64, P66, P71, P72, APM-W251,
APM-W254 and APM-W291 Models
All cage type Modulevel units are shipped with the controller
removed from the chamber assembly and packed separately
in the same carton or crate.
A strap and wire assembly retains and protects the displacer
within the chamber during shipment. The assembly must be
removed through the bottom connection before start-up.
Caution: If reshipping to another location, displacer assembly must
again be secured using same strap and wire assembly.
2.1.3 P68 Models
The side mounting Modulevel units are shipped with the
controller and float and stem assembly removed from the
body and are packed separately in the same carton or crate.
After unpacking, inspect all components to see that no
damage has occurred during shipment.

2.1.4 Transmitter — Receiver Controller Units
Dual head receiver controller models may be supplied to
be integrally mounted to the top mounting or external
cage style Modulevel controls or to be remotely mounted
away from the Modulevel controls. Units supplied with
top mounting Modulevels may be shipped assembled and
connected to the transmitter head or separately for field
assembly. External chambered units will have the receiver
controller head connected to the transmitter head, but separate from the chamber. Any heads shipped unassembled
from the Modulevel will be packed in the same carton or
crate as the control. Handle controllers carefully to avoid
damage to the airline piping.

Mounting
Before assembling control to vessel, check with spirit level
to ensure that the mounting flange is horizontal. Proper
operation of the control depends on the Modulevel controller being within 3° of vertical in all directions. The
head assembly with sensing components is installed first,
then the controller is placed carefully over the enclosing
tube, rotated to desired position, and then locked in place
by securely tightening the locking screw. Check to be certain the controller magnet can move smoothly throughout
its actuating stroke without binding against the enclosing
tube. If binding occurs, loosen the slot-head screw, reposition magnet and tighten screw.
Caution: The spring and stem assembly that protrudes below
the mounting flange on a top mounted Modulevel is very
fragile. DO NOT handle this assembly or place control so
that any amount of force is exerted on the spring and stem
assembly. Proper operation of the control requires that
this assembly is not damaged or bent.
Caution: Displacer spring and stem are fragile. Do not drop displacers into tank. Hand feed cable into position to avoid bending stem.
Caution: All Modulevel units are shipped from the factory with the
enclosing tube tightened and the controller head set
screw locked to the enclosing tube (see figure 2, page 7).
Failure to loosen the set screw prior to repositioning the
supply and output connections may cause the enclosing
tube to loosen, resulting in the possible leakage of the
process liquid or vapor.
NOTE: Since controller is rotatable through 360°, it is important to
make certain controller locking screw is tight before installing
air or gas connections.
The supply and output air or gas connections provided on
the Modulevel are 1⁄4" NPT. These connections are clearly
indicated on the side of the controller. The filter-regulator
(if furnished) is to be set to deliver a 20 psig supply
pressure to a 3–15 psig output controller or a 35 psig supply pressure to a 6–30 psig output controller. The main
supply pressure to the regulator should be between 25 and
250 psig (or 40 and 250 psig) and connected to the inlet
side of the regulator. In order to protect the instrument
from contaminants, clean, dry air or gas must be used as
a supply medium.
Caution: Do not overtighten fittings in supply and output connections. Overtightening may crack the housing outlets.
10
48-620 Modulevel Pneumatic Liquid Level Control
Caution: Operation of all buoyancy type level devices should be
done in such a way as to minimize the action of dynamic
forces on the float or displacer sensing element. Good
practice for reducing the likelihood of damage to the control is to equalize pressure across the device very slowly.

Check to be certain there are no tubes, or other
obstacles in the vessel to interfere with the
operation of the displacer. Stillwells are recommended where a continuous agitation or
motion is prevalent.
NOTE: Stillwell installation should be checked to be certain tube (or pipe) is plumb. An out-of-plumb still
well may restrict displacer movement. Also,
ensure that the stillwell is vented at the top to
allow the liquid to rise in the tube with level
movement.

The external cage type Modulevel should be
mounted on the side of the tank or vessel with
either side/side connections or side/bottom
connections, as shown in Figure 7. Mid-range
mark on control cage should be aligned to
correspond with desired control level in tank
or vessel.
NOTE: It is essential that the external cage assembly be
mounted plumb to ensure frictionless operation
of its internal displacer.
It is recommended that isolation valves be
installed in each equalizing line to the cage as
well as a drain valve at the bottom of the
chamber (refer to Figure 7). Equalizing lines
should be sized at least as large as connections
provided on the cage.

2.2.3 Side Mount Models – P68
Side mount controls mount horizontally to any
tank or vessel through a flanged or threaded pipe
connection. Refer to the illustrations on page 31 for
threaded nozzle and flanged mounting dimensions. It is
essential that the control be mounted horizontal.
NOTE: To allow the 3" float to pass through the nozzle, the nozzle
bore diameter must not be less than 3.00" schedule
40 pipe size.
2.2.4 Transmitter – Receiver Models
Check installation considerations described for either top
mount or cage type mounting units and apply those
appropriate for joint installations with receiver controllers.
Figure 8 shows a typical piping installation of a receiver
controller to a top mounted transmitter type Modulevel
control. A chamber type Modulevel installation would be
the same, with obvious physical differences on a side of
tank installation. Piping for a separate receiver controller
would be done in a similar manner except unit would be
remotely wall or panel mounted in a control house or
installed at or near the control valve.
NOTE: Refer to page 49 for detailed assembly of receiver controller to
a transmitter type Modulevel controller.
Check alignment of mounting bracket for receiver controller to be certain top surface of collar is flush with top
head assembly so that tops of both controller heads are in
the same plane.

All pneumatic (piping) connections should
have threaded joints, sealed with Teflon thread
tape or pipe compound suitable for use on
pneumatic lines; 1⁄4" pipe size or

Actio
1. Check supply pressure:
After appropriate piping has been made to the
filter regulator and output connections, and
checked for leaks, the supply gauge, shown in
Figure 9, should indicate 20 psig (35 psig for
6–30 psig controllers).
2. Check control action:
To check controller action, manually rotate the
magnet carriage to simulate an increase in level.
Note the direction of the output pressure
change. (Rising level will increase the output
pressure on direct acting controllers.
Conversely, rising level will decrease the output
pressure on the reverse acting controllers.) The
action cam and level adjustment knob must
both indicate the same action
Should it be required to change the controller
action, the action cam can be manually rotated
180° to the desired action. Make certain that
the notch in the cam is set into the tab of the
pilot nozzle assembly. Cam actions are clearly
marked on the cam face as indicated in Figure
10. A zero adjustment will normally be required
upon change.
NOTE: It is also important that the level adjustment knob
scale action be compatible with the cam action. The
level adjustment knob scale is printed DIRECT
ACTION on one side and REVERSE ACTION on the
other. To change scales, remove level adjustment
knob and turn over level scale. Replace knob with
same orientation on shaft as before removal.
3. Check level indicator zero setting.
A level indicator is furnished with each

With the system at operating temperature, adjust level of
process liquid in the tank (or vessel) to allow the displacer to
"hang-free" above the liquid. The pointer on the level indicator should read zero percent on the indicator scale. Refer
to Figure 11. To adjust, loosen calibration adjustment screw
at the top of the indicator scale and move scale until the
pointer is aligned to zero. Retighten adjustment screw.

Figure 11 shows a liquid specific gravity of .8 with a corresponding level reading of 45% and a process temperature of
approximately +250° F (+121° C). An adjustment is
provided on the level indicator to calibrate the pointer and
indicator scale when control is at operating temperature.

4. Adjust the proportional band and the level:
(The proportional band is the span setting.) The
proportional band adjustment knob, located adjacent to
the pilot nozzle assembly, sizes the proportional band as a
percentage of the displacer length. When the proportional
band is set at 5, the output range will correspond to 50%
of the total displacer length. For example; on a control
with a 14" displacer, a proportional setting of 5 will
result in full output range over a 7" level change.
Figure 11
Level Indicator
(The level adjustment is the control set point.) The
level adjustment knob, located just below the supply
pressure gauge, positions the midpoint of the proportional band on the displacer. For example; on a control
with a 14" displacer, a level setting of 5 will locate the
midpoint of the proportional band 7" from the bottom
of the displacer.

DIAL SETTING FOR LEVEL & PROPORTIONAL BAND
5.1 Set the magnet carriage slide bar to the correct liquid
specific gravity for your application.
5.2 To check the zero adjustment, bring the liquid level
up until the level indicator reads the desired level set
point. Set the zero adjustment screw until output
pressure gauge reads 9 psig.
6.
Figure 13
Dual Setting for Level & Proportional Band
Set the level and proportional band for your application. Use calibration chart and instructions given in
Figure 13 to select the level and proportional band
dial settings based on the specific gravity of liquid to
be measured.
To check the level and 3–15 settings:
Adjust the liquid level until the level indicator reads
the low value of the desired span range in terms of %
of displacer length. The output pressure should read
3 psig. Adjust the liquid level to the maximum value
of the desired span range in terms of % of
displacer length. The output pressure should read
15 psig.
2.3.1.1 Calibration Chart instructions
To set level:
1. Determine the desired level set point in terms of %
of displacer length.
2. Trace desired level from left to right to the specific
gravity line for the product.
3. Trace down from where the two lines intersect to the
appropriate dial setting.
4. Adjust the level setting on the controller to this value.
To set proportional band:
1. Determine the desired proportional band in terms of
% of displacer length.
2. Trace from left to right to the specific gravity line for
the product.
3. Trace down from where the two lines intersect to the
appropriate dial setting.
4. Adjust the proportional band setting on the controller to this value.
NOTE: If required, small readjustments can be made at the level and
proportional band knobs. To increase proportional band, the
band knob is turned to a higher number. For best control, it is
normally desirable to set the proportional band at the narrowest
setting which will not produce cycling. To raise the level, the
level adjustment knob is rotated in the desired direction indicated on the dial face.
48-620 Modulevel Pneumatic Liquid Level Control

2.3.2 Reset Controllers
Each Modulevel control is factory calibrated before shipment for 30% span and minimum reset. The following
calibration and adjustment procedures are recommended
for all reset controllers:
1. Check to make sure the reset knob is fully counterclockwise.
NOTE: This effectively reduces the reset time to a minimum, but does
not completely eliminate reset.
2. Follow the calibration steps 1 through 4 for proportional controllers beginning on page 13.
3. Use the calibration chart, Figure 13, to select the level
and proportional band initial settings, based on the
specific gravity of the liquid to be measured.
4. Adjust the reset clockwise until stable control is
maintained.
5. Set the magnet carriage slide bar to the correct liquid
specific gravity for your application.
The following adjustment procedure can be used to calibrate the reset controller to your specific application by
adjusting the liquid levels:
Alternate method to calibrate reset
1. Set the proportional band index to 10. (This setting is
comparable to 100% for S.G. equal to 1.0.)
2. Turn the reset dial fully counterclockwise.
3. Slowly open downstream and upstream manual control
valves and close by-pass valve.
4. Adjust control point to desired level by means of level
adjustment knob.
5. Narrow the proportional band until a cyclic control
condition occurs. Then, widen the proportional band
by approximately 20% to give stable control.
6. Decrease the reset time until a cyclic condition again
occurs. Then, increase the reset time until stable control is maintained.
7. Normally the narrowest proportional band and fastest
reset timing required to obtain stability will produce
the optimum control. It is recommended that a
momentary load upset is then produced to further
check system stability and response. (Load can be
imposed by moving magnet carriage manually.)
NOTE: Allow system enough time to stabilize after each adjustment.
16
48-620 Modulevel Pneumatic Liquid Level Control
2.3.3 Transmitters
For Modulevel transmitters, the output signal is directly
proportional to the level on the displacer. To calibrate a
Modulevel transmitter:
1. Follow steps 1 through 3 for Proportional Controllers
(page 13).
2. Set the zero adjustment knob to a vertical position
(arrow straight up at 12 o’clock).
NOTE: Don't confuse the zero adjustment knob with the zero screw
located on top of the pilot nozzle assembly.
3. Set the pointer on the magnet carriage slide bar to the
process specific gravity.
4. Set the specific gravity knob to the process specific
gravity.
NOTE: The specific gravity adjustment sets the span for the unit.
5. Rotate the magnet carriage on the visual level indicator by hand, until the pointer reads 50% of displacer
length.
6. While holding the magnet carriage at 50%, adjust the
zero screw to obtain 9 psig output pressure for 3–15
psig units (or 18 psig output for 6–30 units).
7. Rotate the magnet carriage by hand to 0% displacer
length. The output should be 3 psig. If it is not,
slightly adjust the specific gravity knob to obtain
3 psig output pressure.
8. Rotate the magnet marriage by hand to 100%
displacer length. The output pressure should be
15 psig. If it is not, slightly adjust the specific gravity
knob to obtain 15 psig output pressure.
9. Recheck the midpoint (50% displacer). Adjust the
zero screw to obtain 9 psig output pressure if it
has changed.
10. Recheck the zero output and full scale output.
The Modulevel transmitter has now been calibrated
using the level indicator to simulate process level. If a
more precise calibration to the actual process conditions
is required, the above procedure can be performed
using actual process level on the displacer to set the
calibration points.
48-620 Modulevel Pneumatic Liquid Level Control
17
2.3.4 Receiver Controllers
1. Connect the output from the transmitter to the receiver
controller input at the rear of the receiver controller
housing.
2. Connect a separate supply and output at the right side
of the receiver controller housing.
3. Set the proportional band knob at 100 (100%).
4. Set the direct acting knob at 5 (50%). The output
gauge should read the same as the transmitter output.
If it does not, adjust the zero knob on the receiver
controller until both readings are the same.
To increase or decrease span distance, turn the proportional band knob to the setting desired, for example,
50 = 50% of span. To move the span mid-point, turn
the direct action knob to the setting desired.
For a reverse acting output, from a direct acting
transmitter output, invert the spring/bellows assembly
so that the bellows are on top. Recalibrate as described
above.
Remove the direct acting indicator plate, and turn it to
reverse acting. Recalibrate as described above.
If reset is included with the receiver controller, turn the
reset knob fully counterclockwise and calibrate as
described above.
Adjust reset clockwise until stable control is maintained.
2.3.5 Differential Gap
1. Follow steps 1 through 4 of Proportional Controller
Calibration section. Refer to pages 13 through 17,
except the output is 0–20 psig or 0–35 psig with
no mid-range adjustment.
NOTE: When checking the control action for a direct action differential gap unit, set the cam to reverse action; for a reverse action
differential gap unit, set cam to direct action.
2. Check that the pilot nozzle assembly is set up for differential gap operation. Figure 10 on page 13 illustrates
the pilot nozzle flapper configurations used for the two
control modes, proportional and differential gap. If
your unit is already set up for differential gap mode,
proceed to step 3.
18
48-620 Modulevel Pneumatic Liquid Level Control
To change the control mode:
a. Loosen the tube clamp screw.
b. Remove the zero screw from the pilot nozzle assembly.
c. Remove both screws and top plate from the pilot
nozzle assembly.
d. Flip the pilot nozzle assembly 180° and install
screws with top plate in position.
e. Install the zero screw in the pilot nozzle assembly.
f. Rotate the tube clamp to horizontal and tighten the
tube clamp screw. The cam follower should now rest
on the action cam. If it does not, readjust bracket
without crimping the tube.
NOTE: Make sure the tube is not kinked and does not interfere with
the carriage and the nozzle lever.
g. Change the controller action. For direct action, set
the cam to reverse acting; for reverse action, set the
cam to direct acting.
3. Check zero output. Set level adjustment knob to 5 or
vertical position. Set proportional band knob to 3.
Place level indicator at 35% position (65% position for
reverse action units). Adjust zero screw to get supply
pressure value output; then, slowly readjust the zero
screw until output suddenly decreases to zero.
4. Check 20 psig or 35 psig output. Slowly move the
attraction sleeve to 65% (35% for reverse action units),
at which point the output should suddenly rise to
supply pressure. If not, adjust the proportional band
knob until it does.
5. Set the level and proportional band for your application.
2.3.6 Interface Models
For an interface application, the Modulevel has been
factory precalibrated to operate in liquids with specific
gravities supplied by the customer. The displacer is
weighted to obtain a zero (3 psig or 6 psig signal) with
the displacer fully submerged in the lighter liquid only
[15 psig or 30 psig with displacer covered with the heavier
fluid]. The indicator arrow should be set to the difference
between the two specific gravities of the liquids.
Follow the procedures given for installation and calibration of proportional controllers. Refer to pages 13 through
17. Keep in mind that the "hang–free" or zero setting
is obtained with the displacer fully submerged in the
lighter liquid, and completely uncovered by the interface
(heavier liquid).
48-620 Modulevel Pneumatic Liquid Level Control
19
As is indicated in the Calibration section for proportional
controllers, the signal should be at 9 psig or 18 psig output with the interface level at the control set point
(level knob setting) on the displacer. Because of the reduced
displacer motion for interface applications, the proportional
band should be set as wide as possible, with a minimum
of 50%.
2.3.7 Electric High/Low Limit Switches
The Pneumatic Modulevel is available with optional builtin, adjustable electric high/low level limit switching. This
economical, optional feature is well-suited to numerous
applications where a combination pneumatic control and
electric switch actuation is desired.
The Pneumatic Modulevel is used to pneumatically position a diaphragm-type feedwater control valve in response
to water level changes in the steam drum. The convenient
addition of electric limit switching provides economical
high and low level alarm indication. These switches are
not intended for primary control purposes.
NOTE: Not suitable for Class I, Div. 1 applications.

Field Modifications and Adjustments
2.4.1 Changing Controller Action
The controller can be changed from direct acting to
reverse acting or vice versa. Should it be required to
change the controller action, refer to step 2 in the
Proportional Controllers section of Calibration.
Refer to page 13.
2.4.2 Proportional Band Models to Differential Gap
A proportional band controller can be changed to operate
in the differential gap mode. For the appropriate procedures, see the Differential Gap section on page 18.
2.4.3 Pneumatic-to-Current (P/I) Converter
Modulevel units are available with a P/I transducer to
provide an electronic output signal proportional to liquid
level change. Refer to the manufacturer's instructions
supplied with the transducer.

2.4.4 Reset Installation
Reset
Bellows
Spring
Reset, when added to a proportional controller, acts to
maintain the controlled liquid level at the desired control
point while eliminating any sustained offset from this
point.
The reset adjustment is accomplished by manually adjusting a precision needle valve. The reset dial is calibrated
from .03 to 1.0 minutes per repeat, with short intervals at
the low end of the scale to give precise settings. The reset
timing refers to the time in minutes required for the reset
to produce an additional output pressure change equal to
the previous change caused by proportional action.

Troubleshooting
3.1.1 Installation
The magnet carriage assembly binds at either the
magnet or the indicator scale.
1. The magnet binds on the enclosing tube. Loosen the
retaining screw on magnet bracket and adjust the
magnet alignment.
2. The carriage binds on the indicator scale. Check for
damaged, bent, or loose parts.
3. Check for proper mounting of the controller head.
3.1.2 Calibration
Signal pressure does not change with simulated level
change or unit won't calibrate properly.
1. Make certain the output gauge is operational.
2. Make certain the supply gauge reads 20 psig for
3–15 models or 35 psig for 6–30 models.
3. Check for proper calibration settings, refer to appropriate calibration instructions on pages 13 through 18.
4. Check the proportional band and level settings for
proper process specific gravity. Refer to the calibration
chart, Figure 13 on page 15, in the Calibration section,
for settings corresponding to process specific gravities
other than 1.0.
5. The level indicator should be set for the proper process
temperature.
Cannot obtain proper midspan output (9 psig for
3–15 models or 18 psig for 6–30 models).
1. Adjust the zero adjustment screw.
2. Check if reset is included, the output signal will not
be steady.
Constant high output (pressure does not drop after
manually moving the carriage so that the flapper drops
away from the nozzle).
1. Clogged exhaust nozzle from contamination or poor
quality air supply. Clean nozzle by removing the small
screw on the top of the nozzle and blow out any foreign material, or run fine monofilament type line
through the opening.

1. Check for a clogged relay/wiper by depressing the
orifice clean out plunger. If this does not solve the
problem, the relay may be internally damaged.
Consult the factory.
2. Check for proper supply pressure, described above.
3. Check for leaks at all field connections and tubing.
4. Check calibration settings.
3.1.3 Operation
Control valve continually oscillates or hunts.
1. Proportional band setting is too narrow. To ensure that
the optimum proportional band setting has been made,
create a momentary load upset by manually moving the
magnet carriage and allowing the controller to again
come into balance. If a cyclic condition recurs, widen
the band slightly and repeat the above procedure until
stability is maintained.
2. Distance between the control valve and Modulevel controller is too great (time lag). Install volume booster in
the signal line.
3. If reset is included:
The reset response setting may be too fast. Increase the
reset time until stable control is maintained
Excessive offset. Check the reset line for leaks; these
connections must be airtight.
No output change as level changes.
1. Check that all gasketed joints on the relay are tight.
2. Check for leaks.
3. Depress relay/wiper plunger since the orifice may be
plugged.
4. Remove the enclosing tube and inspect it for internal
buildup.
5. Unbolt the head assembly and check for displacer
interference.
48-620 Modulevel Pneumatic Liquid Level Control
25
6. Remove parts from the head assembly and inspect
internal components.
7. Consult factory.
8. Check sizing and operation of control valve. An oversized valve or excessive friction are possibilities.
9. Check the output capacity. Controllers tend to be
unstable when dead-ended due to their high degree of
sensitivity. This condition is particularly aggravated
when coupled with 1 and 8 above.

ASSURED QUALITY & SERVICE COST LESS
Service Policy
Return Material Procedure
Owners of Magnetrol may request the return of a control
or any part of a control for complete rebuilding or replacement. They will be rebuilt or replaced promptly. Controls
returned under our service policy must be returned by
Prepaid transportation. Magnetrol will repair or replace
the control at no cost to the purchaser (or owner) other
than transportation if:
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material
Authorization” (RMA) number be obtained from the
factory, prior to the material’s return. This is available
through Magnetrol’s local representative or
by contacting the factory. Please supply the following
information:
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim
to be covered under the warranty.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be
charges for labor and the parts required to rebuild or
replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If
this is desired, notify the factory of both the model and
serial numbers of the control to be replaced. In such
cases, credit for the materials returned will be determined
on the basis of the applicability of our warranty.

All shipments returned to the factory must be by prepaid
transportation.
All replacements will be shipped F.O.B. factory.
No claims for misapplication, labor, direct or consequential damage will be allowed.
