Following additional actions have to take place:
Replace the power interface board SDCS-PIN-4 of units D1 to D4.
SDCS-PIN-4
The SDCS-PIN-4 is located between the heat sink and the electronic tray. It
operates continuously, because it supplies the drive electronics even when the
armature current is switched-off. Therefore all its components are exposed to
hot conditions.
Additionally the electrolytic capacitors on the SDCS-PIN-4 are aging. The
SDCS-PIN-4 also is equipped with several capacitors which are sensitive to
high ambient temperature.
Where used:
DCS800-S0x-0020, …, DCS800-S0x-1000 D1 to D4
Aging of the electronic card result in:
1. Damage other devices
2. Trip the drive and cause break-down time
