Applications

For applications with load currents exceeding the sensor current ranges

use an external CT to reduce the current to an acceptable value. For

example, to measure a 500 Amp load current, use a 500A:5A CT and wrap

the CT secondary through the CS-625 and place the CS-625 in the low

range.

For applications with very small load currents (such as less than 1 Amp),

wrap the monitored conductor through the sensor aperture several times

to increase the current measured by the sensor. For example, to monitor

a 0-1 Amp load with a CS-625, wrap the conductor through the sensor

aperture 5 times so the sensor actually sees 0-5 Amps. Be careful the

combined current of total of the wraps does not exceed the selected

current range.

For any application with multiple wraps, note that the CS-625 maximum

current rating must be divided by the number of wraps. For example,

with one wrap the maximum current is 175 Amps, with 5 wraps the

maximum current is 175/5 = 35 Amps. Ensure the load current is < 35

Amps or the device may overheat and be damaged.

Calibration

With the sensor installed and range jumper set, turn on the monitored

load (motor, heater, etc.) and allow it to run normally. Rotate the setpoint

knob counterclockwise several times to make sure switch is open. Then

slowly turn the knob clockwise until the switch closes. Turn clockwise

slightly more to eliminate false switching.

The CS is now set to detect a current condition. A voltmeter can be used

across the contacts to verify switch operation.
