Calibration of Adjustable Trip Point

The adjustable current switch has an operating range of 
0-200 Amps or 0-250 Amps. Do not exceed! The 
adjustable current switch comes with its fifteen-turn 
adjustable potentiometer set counter-clockwise 

 to 

its maximum position. The adjustable current switch can 
monitor Under load, Normal load and Overload 
conditions, depending on how it's set. The procedure 
below is for Normal load condition for part numbers 
CSS-O-A300-001 and CSS-O-A200-001.

Normal loads

With power on and the adjustable current switch on the 
proper range, turn the fifteen-turn adjustment 
potentiometer clockwise 

 until the red LED turns on 

and stop immediately. The adjustment switch is now 
tripped. The adjustable current switch Hysteresis (Dead 
Band) is 10% of the trip point typically.

TROUBLESHOOTING

Table 2. Resistance Readings For Good Unit.

Problem

Solution

Red LED is on but the 
current switch didn’t activate.

Disconnect the wires from the current switch output. Measure the resistance across the 
contacts with an Ohmmeter. See Table 2 below for resistance readings for a good unit.

Red LED didn’t turn on and 
the current switch didn’t 
activate

Verify that the conductor you are monitoring is above the adjustable trip point. If the 
sensor is monitoring less than the adjustable trip point, looping the wire may be 
required. See Fig. 3.

Sensor doesn’t switch at all, 
regardless of current level.

Adjustment potentiometer is probably set to its maximum or minimum position. Turn the 
potentiometer clockwise all the way and verify if the LED switches from red to green.
