4.6 Compressor motor circuit

breaker calibration

8 | BC317523579312en-000101

Below we show step by step how to correctly calibrate motor circuit breaker dedicated to the

compressor.

Fig 15. When the system is started for first time it's

suggested to calibrate the motor circuit breaker on the

compressor power circuits. Using an ammeter verify the

effective absorption.

Fig 17. To carry out the calibration, use the adjustment

screw on the front of the motor protection switch.

Once the electrical connections, checks and calibrations have been completed, the electrical panel

can be closed.

Fig 18. Close the front panel, making sure that all cables

are inside the box and that the box gasket is correctly

housed.

Fig 20. Power up the panel and carry out thorough reading/

programming of all the parameters.

Fig 16. Make the motor circuit breaker calibration

basing on the measured absorption. Any way the set up

value must not be higher than the one expected by the

compressor manufacturer.

Caution: incorrect calibration may cause compressor

failure or unwanted action of the motor protection switch.

Fig 19. Tighten the front panel using the 4 screws. Refit the

cover of the screws on the right side.
