Indicator LEDs and operation indication messages

The operation of REM 610 can be monitored via the HMI by means of LED
indications and text messages on the LCD. On the front panel of the relay there are
three indicator LEDs with fixed functionality: a green indicator LED (ready), a
yellow indicator LED (start/alarm) and a red indicator LED (trip). In addition, there
are eight programmable LEDs and an indicator LED for front communication. Refer
to the Operator's Manual for a more thorough presentation.
The messages on the LCD have a certain priority order. If different types of
indications are activated simultaneously, the message with the highest priority will
appear on the LCD.
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

Motor running time counter

The motor running time counter provides history data since last commissioning. The
counter counts the total number of motor running hours and is incremented when
one or several phase currents have exceeded twelve per cent of the FLC of the motor
for 100 running hours. The running time is stored in the EEPROM. The counter can
be read via the HMI but changed only via parameter V53.
