10.7.1

Checking the Distributor Cabinet Overtemp and Fan Function (CAN Control)

WARNING - High Voltage!

All electrical works at the system may only be carried out by qualified workers.

Power terminals are located in the area of the heating cassette and transformer
overtemperature controllers. Touching these power terminals is dangerous to life.

Avoid touching the power terminals by all means.

Readjust the Overtemperature Monitors to the initial control temperature after the
overtemperature tests.

1. Check if all heating zones in the stacks are cyclically polled for overtemperature

every 20-30 s per heating zone.

2. Visually inspect the spike thermocouples of the heating cassette.

3. Check the heating power switch-off in case of overtemperature.

—

Disconnect a spike thermocouple.

—

The heating must switch off.

—

Observe the power display. The heating relay switch must switch off, listen for
switching sound.

4. Check the overtemperature controller for heating cassette. The heating power

must be switched off in case of a heating cassette overtemperature.

—

Unplug the cable from the temperature controller.

—

The heating must switch off.

—

Observe the power display. The heating relay switch must switch off, listen for
switching sound. After the test, plug in the cable again.

5. Check the overtemperature controller for the transformer.

—

Unplug the cable from the transformer temperature controller.

—

The CMI user interface must display a warning message. After the test, plug in
the cable again.

6. Check the function of the fans between the plug-in units. Exchange defective fans

immediately. Insufficient cooling leads to locally increased temperatures and
failures in electronic components.

10.7.2

Checking the Distributor Cabinet Overtemp. and Fan Function (19"-Rack)

Readjust the Overtemperature Monitors to the initial control temperature after the
overtemperature tests.
