DESCRIPTION
The Model 4093 is a compact, socket mounted Liquid
Level Controller that operates by monitoring the
conductive liquid resistance between probes.
The unit monitors two liquid levels and responds as a
pump-up or pump-down control as determined by the
switch setting on the top of the unit.. The green LED
indicates pump operation while the potentiometer
allows the user to adjust probe sensitivity.

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 4093.
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 2 and 7 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 4093 into the socket and apply power.
Set the SENSITIVITY control as described below.
Connections to the probe are the same for Pump-Up or
Pump-Down. Connect pin 8 to a probe set at the
highest level of liquid in the tank. Connect pin 6 to a
probe set at the lowest level of the liquid in the tank.
Connect pin 5 to a probe that is set to a point lower than
the low probe. If the tank is made of a conductive metal, pin
5 (common) can be connected to the tank.
NOTE: When installing the Model 4093 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.
ADJUSTMENT SETTINGS
Set the SENSITIVITY control knob to the maximum
counter-clockwise position. Do not use excessive
force. Adjust SENSITIVITY as needed.
TYPICAL APPLICATION
Shows No Power Applied
