voltage supply)
The proper operation of the voltage supply unit can be checked via the LEDs of the
SC200 and the LEDs of the rectifier modules (if available) as well as in the display win-
dow of the SC200.
Table 7.4 provides an overview of LED colours of voltage supply unit constituents and
describes them in detail.
Table 7.5 provides an overview of the possible alarm states and the corresponding
alarm indicators. The visual indicators are shown on the display window of the system
controller.
Proceed as follows to check operating statuses of the voltage supply unit:
Preparation:
The electrical connection must be made and commissioning completed.
Carry out the following steps:
1. Check the LEDs of the SC200 and the rectifier(s). The green LEDs must light per-
manently.
2. Check the display window of the SC200. No alarms may be displayed.
The function test has been completed.
