PROGRAMMING NOTES
1) The MODE key allows reversing the programming steps according to the sequence 28-26-8-1
2) The TEST key allows exiting programming without saving the modified data.
3) After 1 minute's keyboard inactivity programming is abandoned without saving the data.
4) During programming the control unit does not control/protect the monitored machine.
5) At the end of programming the control unit is restarted and the FAULT relay is disabled until the unit is fully restarted.
6) If pressing ENT, “Err” appears, it means that one of the following mistakes has been made:
ERR ALL. = ALARM ≥ TRIP
ERR FAN = FAN-OFF ≥ FAN-ON. (FAN1 OR FAN2)
ERR INT = INT FAN-OFF ≥ FAN-ON (FAN1) DELTA <10°C
The device automatically prepares itself for the programming step of the error committed
NOTE: EVERY TIME THE CONTROL UNIT PROGRAMMING, WITH CONFIRMATION OF DATA SAVING, THE
VALUES STORED IN T-MAX ARE RESET AT THE TIME OF STORING.
