The SOR

1510 Level Switch mounts into the side of a vessel. Electric switching action is

provided by the float moving a magnet into the field of a hermetically sealed reed switch

capsule.

The unit may be mounted for either high or low liquid level alarm by rotating the switch

body to the proper position. The body wrench flats provide for ease of rotation and proper

positioning. See decal on housing.

Before Installation of the Level Switch:



Inspect the unit for any shipment damage.



Check for mechanical clearance of

the float. Float must move freely without binding throughout its stroke.



Use an acceptable thread compound when installing unit to ensure a leak-free fit and to

avoid thread galling.



To achieve required function, install the unit according to the nameplate instructions

shown here.

NOTE: If you suspect that a product is defective, contact the factory or the SOR Representative

in your area for a return authorization number (RMA). This product should only be installed by

trained and competent personnel.

Safety Integrity Level (SIL) Installation Requirements The SOR pressure switches have been evaluated as Type-A safety related hardware. To meet the necessary installation requirements for the SIL system, the following information must be utilized: Proof Test Interval shall be one year. Units may only be installed for use in Low Demand Mode. Products have a HFT (Hardware Fault Tolerance) of 0, and were evaluated in a Form 1538 (03.12) ©2012 SOR Inc. 1oo1 (one out of one) configuration.

Electrical Connection Ensure that the wiring conforms to all applicable local and national electrical codes and install unit(s) according to relevant national and local safety codes. Electrical connection is free wire leads with a 1/2” NPT(F) conduit connection. Use two wrenches — one to hold the hex conduit connection, the other to tighten conduit fitting. Switching element is a hermetically sealed reed switch.

Wiring for DPDT Relay For Type 1510 Level Switches equipped with DPDT relays, a wiring schematic and pin position schematic is shown below. When the 1510 is actuated, the coil will energize and “make” both NO1 and NO2 while it will “break” NC1 and NC2. This provides a DPDT circuit.

Troubleshooting Symptom Probable Cause Float in actuated position but no output signal.  No power supply.  Switch damaged. (Replace.) Float in de-actuated position but still receiving an output signal.  Switch damaged. (Replace.) Control will not function when installed but operates when removed from process connection.  Inadequate float travel. Float travel restricted by mounting nozzle. See Mounting Requirements. Liquid in vessel at the actuation level but unit does not respond.
