2.4 Monitoring

In order to ensure high operational reliability, various monitoring functions

are incorporated in the PSI 6000 medium-frequency inverter.

There is a thermostatic switch to signal any overload on the PSG 3000 weld-

ing transformer and/or the MF thyristor unit to the weld timer.

The weld timer will then output a ”Thyristor unit fault” message.

When the fault has been cleared, the error message is reset as follows:

D with the reset button on the weld timer front panel

D by an input signal for acknowledgement (type-specific)

D by an input on the BOS-5000 operator interface

D by an input on the Bosch operator terminal (BT)
