Target LEDs and operation target messages

The operation of REM 610 can be monitored via the HMI by means of LED targets
and text messages on the LCD. On the front panel of the relay there are three target
LEDs with fixed functionality: a green target LED (ready), a yellow target LED
(pickup/alarm) and a red target LED (trip). In addition, there are eight
programmable LEDs and an target 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 targets
are activated simultaneously, the message with the highest priority will appear on
the LCD.
The priority order of the messages:
1. Trip Fail
2. Trip
3. Pickup/Alarm
4. Restart disable
4.1. Thermal protection
4.2. Cumulative start-up time counter
4.3. External restart disable

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 FLA 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.
