3.2.3

Inputs and outputs of the TM modules in the control cabinet

Fundamentals

The inputs and outputs of the TM modules extend the digital and possibly analog inputs and

outputs of the Control Unit. The switching logic of the inputs and outputs between the TM

module and the Control Unit are checked.

Test procedure

1. Signals are applied to the inputs of the TM modules and read out at the Control Unit.

2. Signals are defined at the Control Unit and read out at the outputs of the TM modules.

Result

The test is passed if the switching logic matches the information in the circuit diagram.

3.2.4

Fundamentals

Tests are performed according to DIN EN 60146-1. The auxiliary voltages are visually checked

using indicator lights or using a voltmeter.

Test procedure

1. The drive power section is switched off.

2. The auxiliary voltages are switched on.

3. The auxiliary voltages are checked.

Result

The test is passed if all of the auxiliary voltages are available.

3.2.5

Fundamentals

The test reveals whether a message is displayed on the test station computer when a ground

fault occurs.

Test procedure

1. The auxiliary voltage is present.

2. The signal cable for signaling the ground fault is interrupted.
