DESCRIPTION
The Model 4092 Dual Seal Failure Detector is
designed specifically for monitoring the shaft seals of
two submersible pumps.
The probes are installed in the seal cavities of each of
the pumps. 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 will automatically reset
when the fault condition is corrected. The sensitivity is
field adjustable.

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.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
INSTALLATION
Mount the 8-pin socket in a suitable enclosure. A NEMA
-1 approved enclosure, designed for socket-mounted
relays, is available from Time Mark Corporation.(Model
98A498)
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 into the socket and apply power.
Set the SENSITIVITY control as described below.
NOTE: When installing the Model 4092 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.
PIN DIAGRAM
ADJUSTMENT SETTINGS
Set the SENSITIVITY control knob to the maximum
clockwise position. Do not use excessive force.
If either LED indicator is illuminated, adjust the control
knob counter-clockwise, until both lights are off.
