PROGRAMMING NOTES

1) The MODE key allows reversing the programming steps according to the sequence 24-22-12-1
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 (CH1-CH2-CH3-CH4-CH5-CH6-CH7-CH8)
ERR FAN = FAN-OFF ≥ FAN-ON. (FAN1 OR FAN2)
The device automatically switches to the programming step of the mistake.
NOTE: EVERY TIME THE CONTROL UNIT IS PROGRAMMED WITH DATA SAVING CONFIRMATION, THE VALUES
STORED IN T-MAX ARE RESET TO THE TIME OF SAVING.
ATTENTION :
We recommend you check the unit's programming before starting the device.
The default parameters set by TECSYSTEM might not match your requirements.
Programming the device is the end user's responsibility, the settings of the alarm thresholds and the enabling of
the functions described in this manual must be checked (by a specialized engineer) according to the application
and features of the system the control unit is installed on.
