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

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.
