1 Displacer type liquid level switch INSTRUTION MNUL ND PRTS LIST DESRIPTION Magnetrol's displacement type level switches offer the industrial user a 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. OPERTIN PRINIPLE 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). 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. uilt-in limit stops, prevent over stroking of the spring under level surge conditions. 6 Pivot 4 3 Return spring 5 1 Rising level 2 alling level 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. stainless steel displacer is required if the control is to actuate in liquid as well as by the barrier.

UTION: If re-shipping to another location, displacer assembly must again be secured using same strap and wire assembly. fter 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/E for Equipment or protective system for use in potentially explosive atmospheres. E-type examination certificate number ISSeP01TEX027X (intrinsic safe units) or ISSeP09TEX024X (Ex d units). 2. The PED directive 97/23/E (pressure equipment directive).

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. MOUNTIN UTION: Displacer spring and stem are fragile. Do not drop displacers into tank. Hand feed cable into position to avoid bending stem. djust 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. e 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. heck installation of pipe or tube to be certain it is plumb. IMPORTNT: efore 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. WIRIN 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 (250 )] 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. fter 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. heck cover to base fit on explosion proof and vapor tight housings to be certain gasketed joint is tight. positive seal is necessary to prevent infiltration of moisture laden air or corrosive gases into switch housing. onnect 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. 5

PREVENTIVE MINTENNE If the following sections on "What to do" and "what to avoid" are observed, your Magnetrol instrument will operate reliably. WHT TO DO 1. Keep control clean e 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. djust 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. heck wiring carefully and replace at first sign of brittle insulation. Vibration may sometimes cause terminal screws to work loose. heck all terminal connections to be certain that screws are tight. ir (or gas) operating medium lines, subjected to vibration, may eventually crack or become loose at connections causing leakage. heck lines and connections carefully and repair or replace, if necessary. WHT TO VOID 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. sufficient amount of lubricant has been applied at the factory to insure a lifetime of service. urther 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. ertain 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. 6

7 TROULESHOOTIN 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. uses may be blown. Reset button(s) may need resetting. Power switch may be open. ontrolled 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. ssembly 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: s 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. UTION: 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: heck first to be certain liquid is entering tank or vessel. 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. UTION: e certain to pull disconnect switch or otherwise assure that electrical circuit(s) through control is deactivated. lose operating medium supply valve on controls equipped with pneumatic switch mechanisms.. Disconnect wiring from supply side of switch mechanism(s) and remove electrical conduit or operating medium line connections to switch housing.. Relieve pressure from tank or vessel and allow unit to cool.. 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. heck 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.
