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.

Installation
MD Remote Option (includes plundger, 20 foot cable and two crimps.)
 Screw plunger to the top of unit.
 Thread the 20’ cable through the hole in plunger and create a 14 inch top loop as
shown below.
 At the bottom of the cable, a second loop can be created as a handle for actuation at
the desired length.
The unit may be mounted in any of the following installation arrangements:
 1-1/2” NPT half coupling (No full coupling).
 2” NPT full coupling. (Use in conjunction with 2 x 1-1/2” NPT bushing as required.)
 2” NPT pipe tee. (Use in conjunction with 2 x 1-1/2” NPT bushing as required.)
 Optional flanged mounting.
 Optional chamber mounting.

Special Conditions for Safe Use
This apparatus may have a combined nameplate which carries multiple approvals
(intrinsically safe and flameproof). The equipment should be marked as to which protection
method it is installed as and shall not be changed or utilized in any other means than was
originally marked by the end user.
When marked and installed as Ex i equipment, the permanently attached leads must be
suitably protected against mechanical damage and terminated in a suitable junction box or
terminal facility having a degree of protection at least IP20.
When marked and installed as Ex d equipment, the permanently attached leads must be
suitably protected against mechanical damage and terminated in a suitable junction box or
terminal facility.
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.

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.
