1.0 Introduction
Displacement type level switches offer the industrial user a wide
choice of alarm and control configurations. These units utilize
simple buoyancy principle and are well suited for simple or
complex applications.

1.1
Principle of Operation
1.1.1 Displacer Controls
The design of displacer operated level switches is based upon
the principle that a magnetic field will not be affected by nonmagnetic materials such as 316 stainless steel. In this case, the
displacer moves a magnetic attraction sleeve within a non-magnetic enclosing tube and actuates a magnetic switch mechanism.
The enclosing tube provides a pressure seal to the chamber and,
therefore, to the process.

1.3
A spring is loaded with a weighted displacer which is heavier
than the liquid. Immersion of the displacers caused by rising
liquid level imparts buoyancy forces on the displacer allowing the
spring to compress. The attraction sleeve attached to the spring,
moves upward into the field of a permanent magnet . The
movement of the magnet toward the sleeve causes the switch to
actuate. A non-magnetic barrier tube provides a static pressure
boundary between the switch mechanism and the displacer assembly. As the liquid level falls, the displacer lowers, causing the spring
to extend, and moving the attraction sleeve out of the magnetic
field of the switch mechanism. This allows the switch to again
change position and to break or make. See Figures 1 and 2.
Floating Roof Detection
The spring is loaded with a displacer weight suspended from a
stainless steel cable. As the floating roof rises, the weight is lifted
by the roof allowing the spring to compress, the attraction
sleeve to move upward into the field of the switch magnet and
the switch to actuate. As the roof lowers, the weight again hangs
free causing the spring to extend, the sleeve to move downward
and the switch to reset. The displacers are usually fabricated
from ductile metals, such as brass, to prevent sparking when the
displacer makes contact with the roof.

Operating Cycle
1.4
Operating Cycle — Proof-er Control Option
The purpose of the Proof-er is to check the operation of a
displacer control without having to raise the level in the tank.
This is accomplished by pulling downward on the Proof-er
cable. This causes the spring loaded lever arm to lift the switch
actuator, simulating a high or high–high level condition.
When the cable is released, the Proof-er returns the actuator to
its original position resuming normal operation.

Installation
Caution: If equipment is used in a manner not specified by manufacturer, protection provided by equipment may be
impaired.
2.1
Unpacking
Top mounting displacer units are shipped from the factory
with the displacer and cable assembly removed from the
head assembly and packed separately in the same container.
Caution: If reshipping to another location, displacer assembly must
again be removed from the control to prevent damage.
Unpack the instrument carefully. Inspect all units for
damage. Report any concealed damage to carrier within
24 hours. Check the contents of the packing slip and
purchase order. Check and record the serial number for
future reference when ordering parts.
Caution: The threaded connection link and stem protruding from
the head assembly are extremely fragile. DO NOT handle
or place control in a position so that any amount of force
is placed on the stem. Proper operation of the control
requires that the stem 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.
2.2
Mounting
Caution: This instrument is intended for use in Installation Category II,
Pollution Degree 2.
Adjust the displacers on the displacer cable for the desired
switch actuating levels (instruction tag is attached to
cable). Screw displacer cable fitting to threaded connection
link protruding from the underside of control.
Be sure there are no tubes, rods, or other obstacles in the
tank or vessel to interfere with the operation of the displacers. No guides into the tank are necessary unless liquid
turbulence is excessive, in which case a guide pipe or tube
should be at least 1 inch larger than the displacer diameter,
open at the bottom end, and with several vent holes
located above the maximum high level of the liquid.
Check the installation of pipe or tube to be certain it
is plumb.

Caution: Before attaching Magnetrol control to tank or vessel, using
a level, check to see that tank mounting flange is within 3°
of horizontal in all directions. Proper operation of the control depends on the switch housing being plumb.
For floating roof top applications, the displacer switch may
be mounted via flange or threaded mounting on a bracket,
catwalk, etc. or through an opening in an outer dome roof.
Ensure that there are no obstacles to interfere with the
operation of the displacers or weights and that there is a
level surface on the roof beneath the displacer/weight.
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 slowly.
2.3
Wiring
Caution: Level controls are shipped from the factory with the
enclosing tube tightened and the middle set screw, on the
housing base, locked to the enclosing tube. Failure to
loosen the set screw prior to repositioning the conduit
connection may cause the enclosing tube to loosen,
resulting in the possible leakage of the process liquid
or vapor.
NOTE: If control is equipped with pneumatic switch mechanism, disregard these instructions and refer to instruction bulletin on
mechanism furnished for air (or gas) connections.

Switch Mechanism
Most switch enclosures are designed to provide 360° positioning of the conduit outlet by loosening the set screw(s)
located at the bottom of the switch housing base. To rotate
conduit entry:
Loosen set screw(s) at base of switch housing. Refer to
Figure 2.
Rotate switch housing so that conduit entry is
positioned as desired.
Tighten set screws at base of housing.
At the factory, terminal blocks are positioned next to the
conduit entry to facilitate wiring. If repositioning of the
switch mechanisms is desired:
Unscrew and remove switch housing cover. The threads
have been lubricated to facilitate removal.
Loosen the frame mounting screw on each switch mechanism. Refer to Figure 3.
Carefully rotate the baffle plate and all switch mechanisms
together until the terminal blocks are in the desired position.
NOTE: On dual and triple stage controls the correct spacing of the
mechanisms is maintained using brackets that connect the
mechanisms. Take care when rotating the baffle plate and
mechanisms to rotate them as a unit and not one at a time.
This will ensure that the brackets and mechanisms will not be
damaged during repositioning.
4. Ensure that the terminal blocks are aligned vertically to
prevent stress on the brackets and mechanisms.
5. Tighten the frame mounting screw on each switch mechanism.

device to protect the valuable equipment it serves. A systematic program of “preventive maintenance” must be
implemented when the control is placed into service. If the
following sections on “What to do” and “What to avoid”
are observed, your control will provide reliable protection
of your equipment for many years.

What to do
3.1.1 Keep control clean
Be sure the switch housing cover is always in place on the
control. This cover is designed to keep dust and dirt from
interfering with switch mechanism operation. It protects
against damaging moisture and acts as a safety feature by
keeping bare wires and terminals from being exposed.
Should the housing cover or any seal become damaged or
misplaced, obtain a replacement immediately.

NOTES: 1. Rising level closes contacts 5 & 6 and 2 & 3.
2. Falling level closes contacts 4 & 5 and 1 & 2.
1. Dry contact switches should be inspected for excessive
wear on actuating lever or misalignment of adjustment
screw at point of contact between screw and lever. Such
wear can cause false switch actuating levels. See switch
mechanism bulletin supplied with control should switch
adjustment or replacement be necessary.
2. DO NOT operate your control with defective or maladjusted switch mechanisms (refer to bulletin on switch
mechanisms furnished for service instructions.)
3. Level controls may sometimes be exposed to excessive heat
or moisture. Under such conditions, insulation on electrical wiring may become brittle, eventually breaking or pealing away. The resulting “bare” wires can cause short circuits.
Figure 9 – Triple Stage with SPDT contacts
NOTE: Check wiring carefully and replace at the first sign of brittle
insulation.
8
45-610 Displacer Type Liquid Level Switches and Proof-er® Switches
4. Vibration may sometimes cause terminal screws to work
loose. Check all terminal connections to be certain that
screws are tight.
5. On units with pneumatic switches, air (or gas) lines subjected to vibration, may eventually crack or become loose
at connections causing leakage. Check lines and connections carefully and repair or replace, if necessary.
NOTE: As a matter of good practice, spare switches should be kept
on hand at all times.
3.2
What to avoid
1. Never leave switch housing cover off the control longer
than necessary to make routine inspections.
2. Never place a jumper wire across terminals to “cut-out”
the control. If a “jumper” is necessary for test purposes,
be certain it is removed before placing control into
service.
3. Never attempt to make adjustments or replace switches
without reading instructions carefully. Certain adjustments provided for in level controls should not be
attempted in the field. When in doubt, consult the
factory or your local representative.
4. Never use lubricants on pivots of switch mechanisms.
A sufficient amount of lubricant has been applied at the
factory to ensure a lifetime of service. Further oiling is
unnecessary and will only tend to attract dust and dirt
which can interfere with mechanism operation.
5. Never attempt to readjust magnetic attraction sleeve.
It is factory set, and tampering may cause failure of
control while in service, even if manual operation
activates switch.

Reference Information
4.1
Troubleshooting
Usually the first indication of improper operation is failure
of the controlled equipment to function, i.e., pump will
not start (or stop), signal lamps fail to light, etc. When
these symptoms occur, whether at time of installation or
during routine service thereafter, check the following
potential external causes first.
a. Fuses may be blown.
b.
c.
d.
e.
Reset button(s) may need resetting.
Power switch may be open.
Controlled equipment may be faulty.
Wiring leading to control may be defective.
If a thorough inspection of these possible conditions fails
to locate the trouble, proceed next to a check of the
control's switch mechanism.
4.1.1 Check switch mechanism
1. Pull disconnect switch or otherwise disconnect power to
the control.
2. Remove switch housing cover.
3. Disconnect power wiring from switch assembly.
4. Swing magnet assembly in and out by hand to check carefully for any sign of binding. Assembly should require
minimal force to move it through its full swing.
5. If binding exists, magnet may be rubbing enclosing tube.
If magnet is rubbing, loosen magnet clamp screw and shift
magnet position. Retighten magnet clamp screw.
6. If switch magnet assembly swings freely and mechanism
still fails to actuate, check installation of control to be
certain it is within the specified three degrees of vertical.
(Use spirit level on side of enclosing tube in two places,
90° apart.)
7. Check switch continuity with ohmmeter.
NOTE: As a matter of good practice, spare switches should be kept
on hand at all times.
8. If switch mechanism is operating satisfactorily, proceed to
check sensing unit.
10
45-610 Displacer Type Liquid Level Switches and Proof-er® Switches
4.1.2 Test control’s performance
1. Reconnect power supply and carefully actuate switch
mechanism manually, using a non-conductive tool on electrical switch mechanism, to determine whether controlled
equipment will operate.
Caution: With electrical power on, care should be taken to avoid
contact with switch leads and connections at terminal
block.
2. If controlled equipment responds to manual actuation
test, trouble may be located in level sensing portion of the
control (displacers, spring, stem, and magnetic attracting
sleeve).
NOTE: Check first to be certain liquid is entering tank or vessel.
A valve may be closed or pipe line plugged.
3. With liquid in tank or vessel, proceed to check level sensing action by removing switch housing assembly.
Caution: Be certain to pull disconnect switch or otherwise assure
that electrical circuit(s) through control is deactivated.
Close operating medium supply valve on controls
equipped with pneumatic switch mechanisms
a. Disconnect wiring from supply side of switch mechanism(s) and remove electrical conduit or operating medium line connections to switch housing.
b. Relieve pressure from vessel and allow unit to cool.
c. Remove switch housing assembly by loosening set screws
located at the bottom of the housing base.
4. With switch housing assembly removed, inspect attraction
sleeve and inside of enclosing tube for excessive corrosion
or solids buildup which could restrict movement, preventing sleeve from reaching field of switch magnet.
5. Inspect displacer stem and spring assembly to assure it
is not damaged. If stem or spring is bent or otherwise
damaged, movement of the attraction sleeve inside the
e-tube will be restricted, preventing proper function of
the control.
6. If trouble is still not located, proceed to remove the entire
sensing unit from the tank or vessel by unbolting head
flange or unscrewing mounting bushing. Inspect displacer
assembly and all internal parts for any signs of damage.
Check assembly for binding by supporting head flange or
mounting bushing over the edge of a bench and move
displacer assembly by hand.
NOTE: When in doubt about the condition or performance of a control, contact the factory or consult your local representative.

Service Policy
Return Material Procedure
Owners of Magnetrol controls 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.
