The SOR
®
Type 1710 Electric Level Detector is a horizontally mounted, float-operated level
detector. The Type 1710 is suitable for plant and OEM applications where open or closed
contacts are required to signal the presence or absence of liquid at a discrete level.
When the liquid rises, the float extension arm moves a magnet that repels an internal
magnet de-actuating a microdetector. When the liquid level falls, the float extension arm
moves in the opposite direction, actuating the microdetector (See
). The 1710 is
recommended for use in clean liquids only.
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.

Electrical Power should be disconnected before the cover is removed. Failure to
do so could result in severe personal injury or substantial property damage.
Electrical Connection
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.

Verify that obstructions are not present in the application that would prevent free float
movement throughout the entire range of motion.

Assure that the mounting provides a horizontal alignment of the detector.
Thread a one-foot long pipe into the 3/4”NPT electrical connection for a handle, or use a pipe
wrench on the main body. Tighten the unit onto the process connection by rotating clockwise.

To ensure proper operation, the unit must be mounted with the nameplate at 12 o’clock
(pointing up) and the conduit connection at the 6 o’clock position (pointing down). (See
)
 Detector actuation cannot be reversed by rotating the unit 180°.
 Calibration is provided by SOR. Field adjustments are not recommended.
 Any of the following process connections may be provided with the 1710.
a. 2” NPT full coupling
b. Optional flanged mounting
c. Optional external chamber (See )
Counterbalance area must be free from metallic particles that may attract to
magnetic components in the 1710 model.

Remove the end cover with a spanner wrench to gain access to the terminal block and
detector mechanism.

Pull detecting wires into the detector cavity through the electrical connection. Wire to the
terminal block(s) as shown in . (Select wires which are compatible with temperature
and electrical load required by the application.)

Connect the ground wire to the green ground screw located on the outside of the housing.

Replace the detector cover and tighten. Tighten the cover lock screw to prevent accidental
removal.

Seal the conduit connection with a suitable pipe joint compound to prevent entrance of
atmospheric contaminants.

Test the detector action by varying the liquid level in the tank.
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.

Maintenance
Troubleshooting
 Keep the cover tightly secured to the housing.
 Prevent moisture or dirt from entering the housing when the cover is off.
 Check all screw terminal connections periodically. Vibration may loosen the screw
terminals.
 Clean the float and counterweight mechanism periodically to assure continued free
movement.
 Make no adjustments to the detector mechanism. It is factory calibrated for optimum
performance.
 Apply petroleum jelly or anti-seize compounds to cover threads periodically to
prevent seizing.

To minimize the risk of electrostatic discharge, clean only with a damp cloth.
Do not remove the cover when the unit is energized.
Symptom Probable Cause
The float is in the actuated
position but the detector
does not actuate.
a. The terminal block is wired incorrectly. Check wiring.
b. The unit is installed upside-down. Rotate housing so
that the nameplate faces up.
c. The detector is damaged. Contact the factory.
The float is in the de-actuated
position but the detector remains
actuated.
a. The terminal block is wired incorrectly. Check wiring.
b. The detector is damaged. Contact the factory.
The control will not function
when installed but operates
when removed from process
connection.
a. Float travel is inadequate. Check for internal
vessel obstructions. See Mounting Requirements.
Liquid is in the vessel at the
actuation level but the unit does
not respond.
a. The float pivot pin is bound up or dirty. Clean the
float pivot pin.
b. The unit is installed upside-down. Rotate housing
so that the nameplate faces up.
c. The specific gravity of the liquid is not sufficient
to lift the float.
d.
The float is leaky or collapsed. Contact the factory.
