Checking procedures
INFORMATION
It is recommended to perform the checks in the listed order.
To perform a functionality check of the noise filter PCB
INFORMATION
The noise filter PCB is mounted on the back side of the PCB mounting plate and
therefore NOT easily accessible. Therefore, first perform the functionality check
described below without dismounting the PCB mounting plate.
Prerequisite: Stop the unit operation via the user interface.
Prerequisite: Turn OFF the respective circuit breaker.
1 Remove the required plate work, see "3.17Plate work"[4230].
2 Turn ON the power of the unit.
3 Measure the output voltage of the noise filter PCB on the terminal X1M: 1‑2
and between LC and NC on the main PCB.
Result: The measured voltages MUST be 230VAC.
