This error is triggered because no parameter has as yet been written onto the PULSAR from the superordinated control unit, during operation with the SHCom
The main contactor K2 is monitored by an auxiliary contact. K2 is defective if it does not pick up as soon as the coil current is switched on.
The main contactor K2 is monitored by an auxiliary contact.
If one of the three phase voltages exceeds the nominal value by the tolerance in parameter 'Max Inp Volt Tol', this error is triggered.
If one of the three phase voltages falls below the nominal value by the tolerance in parameter 'Max Inp Volt Tol', this error is triggered.
This fault is triggered if welding takes place with a XX4-PULSAR without having performed 'Controller identification' first.
Every parameter in the PULSAR is defined among other things by a minimum/maximum permissible value.
The digital outputs on plug X9, which are partially used to activate the two contactors K1 and K2, are monitored for short circuit and thermal overload.
The reference voltage of SPI ADC deviates by more than 40 mV. The data on the SPI bus is therefore useless
The IGBT half-bridges are short-circuit-proof.
The IGBT half-bridges are short-circuit-proof.
If the output current of the PULSAR reaches too high a value, it is switched off because of overcurrent to protect the roller heads.
