  • Page 4: Introduction

    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. 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 non- magnetic materials such as 316 stainless steel.

  • Page 5: Installation

    Installation Caution: If equipment is used in a manner not specified by manu- facturer, protection provided by equipment may be impaired. 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.

  • Page 6: Wiring

    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 con- trol depends on the switch housing being plumb.
  • Page 7 NOTE: On high temperature applications above +250° F (+121° C), INTERNAL INTERNAL CIRCUIT CIRCUIT (LEFT) (RIGHT) high temperature wire should be used between control and SWITCH SWITCH first junction box located in a cooler area. On non-hazardous applications, flexible conduit may be used between the con- trol and the first junction box.

    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 sub- jected to vibration, may eventually crack or become loose at connections causing leakage.

  • Page 10: Reference Information

    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.

  • Page 11: Test Control's Performance

    4.1.2 Test control’s performance 1. Reconnect power supply and carefully actuate switch mechanism manually, using a non-conductive tool on elec- trical 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.

    4.1.3 Proof-er If the Proof-er is not functioning properly, listed below are potential problems and corrective action. 1. Proof-er does not return to the down position after it is activated. C USE REMEDY Defective return spring. Replace Spring. Buildup between the shaft Clean Proof-er to and housing restricting remove buildup.
