45-610 Displacer Type Liquid Level Switches and Proof-er® Switches
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 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. 1.2

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 — 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.

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.
Figure 3 Switch Mechanism
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.

Preventive Maintenance
Periodic inspections are a necessary means to keep your level control in good working order. This control is a safety 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.

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.

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.
NOTE: Check wiring carefully and replace at the first sign of brittle insulation.

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
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.

ASSURED QUALITY & SERVICE COST LESS
Service Policy 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: 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. No claims for misapplication, labor, direct or consequential damage will be allowed.
Return Material Procedure 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. 2. 3. 4. 5. Company Name Description of Material Serial Number Reason for Return Application
Any unit that was used in a process must be properly cleaned in accordance with OSHA standards, before it is returned to the factory. A Material Safety Data Sheet (MSDS) must accompany material that was used in any media. All shipments returned to the factory must be by prepaid transportation. All replacements will be shipped F.O.B. factory.
