The following subset of parameters are available for viewing and are accessed using the
<SELECT/RESET> push-button in a cyclic manner. Pressing for longer than 1 second returns to the
start of the cycle. Parameters available are either actual real-time running values or memorised
values as follows:

In addition to the above, when the motor is starting the S/R LED indicates Green-Flashing and when
the motor is running the S/R LED indicates Green-Steady. The value of motor load is held after a trip
and updated when the next start is detected. Total hours run is the total time the relay has detected a
running motor. When the kA illuminates the display value is multiplied by 1000, e.g. to read line
current in kA or hours run in 1000’s of hours.
* FOLLOWING A RELAY TRIP THIS VALUE IS THE STORED PRE-TRIP FAULT VALUE. TO
RESET THE RELAY FOLLOWING A TRIP AND CANCEL THE STORED TRIP
VALUES,(EXCEPT THE STORED MAX/STARTING CURRENT L1, L2 AND L3) PRESS THE
<SELECT/RESET> BUTTON FOR MORE THAN 3 SECONDS, OR RE-START THE MOTOR.
