Under current protection: see 5.8.13 on page 54

5.8.1

Characteristics of protection functions

•

Each protection function has an input for a variable to be observed and inputs for setpoints which are set
via LCU-5 by selecting:

SCU Manager - Module Protection - Settings

•

After having been configured, each protection function is performed autonomously by the Starter Control
Unit.

•

Each protection function has the facility to generate a trip signal to switch off the motor in the event that
one of the setpoints is exceeded.

•

Each protection function (except motor stall) has the facility to generate a warning signal in the event that
one of the setpoints is exceeded.

•

Setpoints are used to define which trip and warning signals can be acknowledged via manual control or
process control.

The status of a protection function can be read-out via LCU-5, by the process controller and on the motor starter
tray.

Protection states:

•

Fault not present.

•

Protection activated, message not yet confirmed by an acknowledge/reset command.

•

Message acknowledged but fault is still present.

5.8.2

Read-out of trip and warning signals

Via LCU-5 and the process controller the following statuses can be read-out (see also table 31):
•

Trip Status indicates which protection has been activated.

•

Trip Acknowledge Status indicates which protection has been activated and also has been confirmed by
means of an acknowledge command.

•

Warning Status indicates which protection gives a warning signal.

•

Warning Acknowledge Status indicates which protection gives a warning signal and also has been con-
firmed by means of an acknowledge command.
