whereas the status indication via a programmable LED can be either latching or non-

start-up time counter or an external digital input signal. For the priority of
indications for the restart inhibit state; refer to section Priority of operation
indication messages.

Latching and non-latching indications
A latching operation indication message will remain on the display until manually
cleared or until replaced by a message of higher priority. However, if the fault is
stable and has not disappeared, the operation indication message and the LED(s) will
not be cleared. An operation indication generated by a non-latching start will
automatically be cleared when the stage is reset.
Priority of operation indication messages
The messages on the display have a certain priority order. If different types of
indications are activated simultaneously, the message with the highest priority will
appear on the display.
The priority order of the messages:
1. CBFP
2. Trip
3. Start/Alarm
4. Restart inhibit
4.1. Thermal protection
4.2. Cumulative start-up time counter
4.3. External restart inhibit
When several protection stages generate starts or alarms, the last start/alarm
indication message will be displayed. When several protection stages trip, the first
trip indication message will be displayed until the time, as specified by the
