Calibrating the compressor motor circuit breaker

Step-by-step instructions for calibrating the motor
circuit breaker for the compressor are given below:
1.
When starting the system for first time, it is advisable
to calibrate the motor circuit breaker on the
compressor power circuits. Use an ammeter to check
the effective absorption.
2.
Calibrate the motor circuit breaker based on the
measured absorption. The set up value must not
exceed that recommended by the compressor
manufacturer.
Warning:
An incorrect calibration may cause compressor
breakdown or bad intervention of the motor circuit
breaker.
3.
To calibrate use the control screw on the front of
motor circuit breaker.
