Introduction / Table of Contents Step One

Intended for side wall installation, the general purpose level switch package provides reliable liquid level
detection with a 16A compact level controller for pump or valve control. The optional flash alarm brings
attention to alarm conditions. Offered in two level sensor technologies, select the type and material based
upon your application media. This liquid level switch package is widely applied in bulk storage and process
tank level applications for high level control or low level control.

FEATURES

 Rugged Polypropylene, Ryton® or PFA sensor for corrosive liquids applications.
 Fail-Safe relay control of pumps, valves or alarms with a 0.15 to 60 second delay.
 Polypropylene enclosure rated NEMA 4X with swivel base for conduit alignment.
 Optional flashing alarm brings immediate attention to level alarm conditions.
 Invert switch changes relay state from NO to NC without rewiring.
 Offered in two sensing technologies for broad application coverage: ultrasonic and vibration.

 Owner’s Manual

RELAY CONTROLLER

The level switch is pre-wired before shipment to the 2-pole terminal strip [(+) & (-)]. The technologies used to
indicate level is either Ultrasonic or Vibration. Both the sensing technologies feature similar wiring/power
configuration. The Compact Relay Controller provides a 1/2” Conduit connection and 6 poles for wire
termination of power and relay contact. Use the AC, AC and GND terminals for providing power. Use the NC,
NC and COM terminals for interfacing to the relay contact.
