MODEL 4092/I
Isolated Dual Seal
Failure Detector
Electrically Isolated Inputs
120VAC Version
Adjustable Sensitivity
Automatic Reset
DESCRIPTION
The Model 4092-I Isolated Dual Seal Failure Detector is
designed specifically for monitoring the shaft seals of two
submersible pumps. All electrical inputs are totally isolated
from each other.
The probes are to be installed in the seal cavities of each of
the pumps. The sensitivity is field adjustable. When a seal
begins to leak, contaminating fluid enters the seal cavity,
lowering the resistance between the probe and the common
connection. If the resistance drops below the sensitivity
setpoint, the corresponding relay and the LED indicator are
activated. The Model 4092/I will automatically reset when the
fault condition is corrected.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.
KEEP THIS DATA SHEET FOR FUTURE REFERENCE.
GENERAL SAFETY
POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 4092/I DETECTOR.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
INSTALLATION
Connect the supply voltage to Terminals 1 and 2 on the
socket.
Connect the load control wiring to the appropriate
terminals on the socket, refer to the Pin Diagram and
Typical Application drawing.
Insert the Model 4092/I into the socket and apply power.
Set the SENSITIVITY control as described below.
NOTE: When installing the Model 4092/I Failure Detector in
areas of high humidity or contamination, it is recommended
that the base area and all exposed metal parts of the socket
be coated liberally with a good quality silicone grease, such as
Dow Corning DC-4 or DC-4X. Insert the unit into the socket
and wipe off excess grease around the base. This will prevent
the entrance of moisture and other contaminates into the base
and socket areas.
TYPICAL APPLICATION
PIN DIAGRAM
ADJUSTMENT SETTINGS
Set the SENSITIVITY control knob for probe A to the
maximum clockwise position. Do not use excessive
force. If the PROBE A LED indicator is illuminated,
adjust the control knob counter-clockwise, until the light
is off.
Repeat this procedure for correct sensitivity on probe B.
Shows No Power Applied
