Do not exceed catalog stated electrical ratings. Improper current input to
detector will cause permanent damage to contacts.
Electrical Connection
The SOR
®
1550 Electric Level Detector mounts into the top of a vessel.
Electric detecting action is provided by the float moving a magnet into the
field of a hermetically sealed reed detector.
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.

Before Installng the Level Detector
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 avoid thread galling.
Electrical connection is free wire leads with a 1/2” NPT(F) conduit
connection. Use two wrenches - one to hold hex conduit connection,
the other to tighten conduit fitting. Detecting element is a hermetically
sealed reed detector.
Wiring schematics shown on page 2.
Ensure that all wiring conforms to all applicable local and national electrical
codes and install unit(s) according to relevant national and local safety codes.

For Type 1550 Level Detectors equipped with DPDT relays, a wiring schematic and pin
position schematic is shown below. When the 1550 is actuated, the coil will energize and
“make” both NO1 and NO2 while it will “break” NC1 and NC2. This provides a DPDT circuit.

Safety Integrity Level (SIL) Installation Requirements
The SOR pressure detectors 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
1oo1 (one out of one) configuration. Form 1538 (03.12) ©2012 SOR Inc.

Special Conditions of Safe Use
The permanently attached leads must be suitably protected against mechanical damage and
terminated in a suitable junction or terminal facility with a minimum degree of protection of
at least IP20.0

Troubleshooting
Symptom Probable Cause
Float in actuated position but no
output signal.
a. No power supply.
b. Detector damaged. (Replace.)
Float in de-actuated positon but
still receiving an output signal.
a. Detector damaged. (Replace.)
Liquid in vessel at the actuation
level but unit does not respond.
a. Leaky or collapsed float. (Replace.)
b. Liquid specific gravity too low.
c. Float stem bound up or dirty. (Clean.)
d. Float travel is obstructed. Verify float
can move freely and is not obstructed
when installed.
