Displacer type liquid level switch BE45-610

Displacer type
liquid level switch
®
DESCRIPTION
INSTRUCTION MANUAL AND PARTS LIST
Magnetrol's displacement type level switches offer the
industrial user a wide choice of alarm and control
configurations. Each unit utilizes a simple buoyancy
principle and are well suited for simple or complex
applications, such as foaming or surging liquids or
agitated fluids, and usually cost less than other types
of level switches.
OPERATING PRINCIPLE
Standard controls
Operation is based upon simple buoyancy, whereby a
spring is loaded with weighted displacers which are heavier than the liquid. Immersion of the displacers in the liquid
results in buoyancy force change, which moves the spring
upward. Since the spring moves only when the level moves
on a displacer, spring movement (1) is always a small fraction of the level travel between displacers (2).
A magnetic sleeve (3) is connected to the spring and
operates within a non-magnetic barrier tube (4). Spring
movement causes the magnetic sleeve to attract a pivoted
magnet (5), actuating a switch mechanism (6) located outside the barrier tube. Built-in limit stops, prevent over
stroking of the spring under level surge conditions.

Proof-er controls
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 chain. This causes the spring loaded lever arm to
lift the switch actuator, simulating a high or high high level
condition. When the chain is released, the proof-er returns
the actuator to its previous position to resume normal operation.
Proof-er floating roof controls
The proof-er roof top control is designed for installation on
'barrier' (floating roof) tanks. The control may be furnished
with a lead displacer to prevent sparking. A stainless steel
displacer is required if the control is to actuate in liquid as
well as by the barrier.
MODEL IDENTIFICATION
A complete measuring system consists of:
1. Code for standard models (each unit is factory calibrated to operate on a given specific gravity within the min and
the max values listed per model) or
2. Code for floating roof models.

UNPACKING
INSTALLATION
Unpack the instrument carefully. Make sure all components
have been removed from the packing material. Inspect all
components for damage. Report any concealed damage to
the carrier withing 24 hours. Check the contents of the
packing slip and report any discrepancies to the factory.
Check the nameplate model number to be sure it agrees
with the packing slip and purchase order. Check and record
the serial number for future reference when ordering parts.
CAUTION: If re-shipping to another location,
displacer assembly must again be secured using
same strap and wire assembly.
After unpacking, inspect all components to see that no
damage has occurred during shipment.
These units are in conformity with
the provisions of:
1. Directive 94/9/EC for Equipment
or protective system for use in
potentially explosive atmospheres. EC-type examination certificate number
ISSeP01ATEX027X (intrinsic safe units) or
ISSeP09ATEX024X (Ex d units).
2. The PED directive 97/23/EC (pressure equipment directive). Safety accessories per category IV module H1.
Nameplate:
- part number
- serial n°
HANDLING
CAUTION: The threaded connection link protruding
from the head assembly is extremely fragile. DO
NOT handle or place in a position such that any
amount of force is placed on the stem. Proper operation of the control requires that the stem is not
damaged or bent.
MOUNTING
CAUTION: Displacer spring and stem are fragile. Do
not drop displacers into tank. Hand feed cable into
position to avoid bending stem.
Adjust the displacers on the displacer cable for the desired
switch actuating levels. (Instruction tag 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 "guided pipe"
or tube should be at least 25 mm 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 installation of pipe or tube to be certain it is plumb.
IMPORTANT: Before attaching Magnetrol control to
tank or vessel, check with level to see that tank
mounting flange or spud is horizontal. Proper
operation of the control depends on the switch
housing being plumb.
WIRING
NOTE: If control is equipped with pneumatic switch
mechanism, disregard these instruction and refer to
instruction bulletin on mechanism furnished for air (or
gas) connections.
Most Magnetrol control switch housings are designed to
provide 360° positioning of cable entry by loosening the set
screw(s) located under the housing base. Diagrams of the
control's internal electrical circuits (switching action
between terminals) will be found in the switch mechanism
instruction bulletin included.
On high temperature applications [above 120°C (250°F)]
high temperature wire should be used between control and
first junction box located in a cooler area. Supply wires
(conductors) are brought into the switch housing, wrapped
around the enclosing tube under the baffle plate and then
brought up to the proper terminals. Excess wire should be
positioned so as not to interfere with switch mechanism or
housing cover.
Some controls are furnished with an explosion proof (cast)
switch housing or a vapor tight (gasketed) type. These housings are used in hazardous locations or when liquid temperature is so low that excessive condensation and frosting of
switch parts is likely. After wiring connections have been
completed, explosion proof housings must be "sealed" at
the conduit outlet with suitable compound or "dope" to prevent entrance of air. Check cover to base fit on explosion
proof and vapor tight housings to be certain gasketed joint is
tight. A positive seal is necessary to prevent infiltration of
moisture laden air or corrosive gases into switch housing.
Connect power supply to control and test switch action by
varying liquid level. If switch mechanism fails to function,
check vertical alignment of control and consult installation
bulletin on mechanism furnished.

PREVENTIVE MAINTENANCE
If the following sections on "What to do" and "what to avoid" are observed, your Magnetrol instrument will operate reliably.
WHAT TO DO
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. In addition, it
protects against damaging moisture and acts as a safety
feature by keeping bare wires and terminals from being
exposed. Should the housing cover become damaged or
misplaced, order a replacement immediately.
2. Inspect switch mechanisms, terminals and connections monthly
– Dry contacts switches should be inspected for excessive wear on actuating lever or misalignment of adjustment screw at point of contact between screw and lever.
Such conditions can cause false switch actuating levels.
Adjust switch mechanism to compensate (if possible) or
replace switch.
DO NOT operate your control with defective or maladusted switch mechanisms (refer to bulletin on switch mechanism furnished for service instructions).
– Magnetrol controls may sometimes be exposed to
excessive heat or moisture. Under such conditions,
insulation on electrical wires may become brittle, eventually breaking or peeling away. The resulting "bare"
wires can cause short circuits. Check wiring carefully
and replace at first sign of brittle insulation.
6
– Vibration may sometimes cause terminal screws to work
loose. Check all terminal connections to be certain that
screws are tight. Air (or gas) operating medium 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.
WHAT TO AVOID
1. NEVER leave switch housing cover of the control
longer than necessary to make routing inspections.
2. NEVER use lubricants on pivots of switch mechanisms.
A sufficient amount of lubricant has been applied at the
factory to insure a lifetime of service. Further oiling is
unnecessary and will only tend to attract dust and dirt
which can interfere with mechanism operation.
3. NEVER attempt to make adjustments or replace switches without reading instructions carefully. Certain adjustments provided for in Magnetrol controls should not be
attempted in the field. When in doubt, consult the factory or your local Magnetrol representative.
4. NEVER attempt to readjust magnetic attraction sleeves
which are factory set. Tampering may cause failure of
control while in service even though manual operation
actuates switches.
TROUBLESHOOTING
Usually the first indication of improper operation is failure of
the controlled equipment to function–pump will not start (or
stop), signal lamps fail to light, etc. When these symptoms
occur, whether at time of installation or during routing service thereafter, check the following external causes first.
–
–
–
–
–
–
Fuses may be blown.
Reset button(s) may need resetting.
Power switch may be open.
Controlled equipment may be faulty.
Stem may be bent causing hang-up.
Wiring (or medium lines) 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.
1. Pull disconnect switch or otherwise assure that electrical circuit(s) through the control is deactivated.
2. Remove switch housing cover.
3. Swing magnet assembly in and out by hand, checking
carefully for any sign of binding. Assembly should
require no force, however slight, to move it through its
full swing.
4. If binding exists, magnet may be rubbing enclosing tube
or pivot sockets may be overly tight. Readjust pivot
sockets as required until a slight amount of side play is
evident. If magnet is rubbing, loosen magnet clamp
screw and shift magnet position.
5. 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 (3°) degrees of
vertical (use spirit level on side of enclosing tube in two
places, 90° apart).
NOTE: As a matter of good practice, spare switches should
be kept on hand at all times.
If switch mechanism is operating satisfactorily, a test of the
complete control's performance is the next likely step.
1. Reconnect power supply and carefully actuate switch
mechanism manually (using a non-conductive tool on
electrical switch mechanism) to dertermine 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 tank or vessel and allow unit to
cool.
C. Remove switch housing assembly by loosening set
screw located immediately below housing base.
4. With switch housing assembly removed, inspect attracting sleeve and inside of enclosing tube for excessive
corrosion or solids build-up which could restrict movement, preventing sleeve from reaching field of switch
magnet.
5. 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 Magnetrol control, return it to the factory. See "Our
Service Policy" on page 16.

IMPORTANT
SERVICE POLICY
Owners of Magnetrol products 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. Magnetrol International will repair or replace the control, at no cost to
the purchaser, (or owner) other than transportation cost if:
a. Returned within the warranty period; and,
b. The factory inspection finds the cause of the malfunction to be defective material or workmanship.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be charges for labour
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.
No claims for misapplication, labour, direct or consequential damage will be allowed.
RETURNED MATERIAL PROCEDURE
So that we may efficiently process any materials that are returned, it is essential that a “Return Material Authorisation” (RMA)
form will be obtained from the factory. It is mandatory that this form will be attached to each material returned. This form is
available through Magnetrolʼs local representative or by contacting the factory. Please supply the following information:
1. Purchaser Name
2. Description of Material
3. Serial Number and Ref Number
4. Desired Action
5. Reason for Return
6. Process details
Any unit that was used in a process must be properly cleaned in accordance with the proper health and safety standards
applicable by the owner, before it is returned to the factory.
A material Safety Data Sheet (MSDS) must be attached at the outside of the transport crate or box.
All shipments returned to the factory must be by prepaid transportation. Magnetrol will not accept collect shipments.
All replacements will be shipped Ex Works.
