Protective functions – Short circuit to 0 V/PE
– Overvoltage-proof to 60 V
2)
– Thermal overload protection
Fault detection Voltage at output despite brake having shut down
Diagnostics possible via:
–
Output SBA
– Error message on device
1) The test pulses of the associated control input #SBC-A are mapped to the output subject to a switching delay.
2) Brake output also shuts down in the event of a fault if there is an overvoltage on the logic supply.
