ERROR: Contactor relay not working (-K XXX)

The system checks the correct operation of the contactors for powering the drives. If the contactor not working properly, it may happen that the motors will have a power supply, even when the safety conditions are not met. This error stops the machine and prevents this.

• In the electrical cabinet, find the contactor with the label number as in the error inscription. Electrically check the operation of each contact with the instrument.
• If necessary, replace the defective element.

If you need additional information, call the Gostol TST service department.
