7.4.2.9 Monitoring motor runtime

The motor-drive unit's runtime can also be monitored by the voltage regulator.

This function is used to identify motor-drive unit malfunctions during the tap-

change operation and to trigger any actions needed.

The corresponding control input must be correctly wired and parameterized to

"Motor running" in order to use runtime monitoring. The motor runtime must

also be set.

The motor-drive unit supplies the "Motor running" signal during the tap-

change operation. This signal is present until the tap-change operation is

complete. The voltage regulator compares the duration of this signal with the

motor runtime set. If the set motor runtime is exceeded, the voltage regulator

triggers various actions:

1. "Motor runtime monitoring" message

2. Continuous signal via output relay "Motor-drive unit runtime exceeded"

(optional)

3. Impulse signal via output relay "Trigger motor protective switch" (optional)
