3.1.2 Testing Sequence from Keypad
The testing sequence is activated by entering the testing menu CoL and setting the parameter to ON.
The phases of the testing sequence are given below:
1) Check that the digital input IN4,conguredas“Genericalarm(NO)” is closed.
2) Activation of the evaporator fan (PUM).
3) Activation of the compressor (COM).
4) Activation of the condensing fan (PUM).
5) After activation of the condensing fan, the two fans and the compressor remain active for 3 minutes.
6) Once 3 min has passed, the testing sequence concludes.
The sequence can be concluded before this by the operator by opening the digital input IN4 (by opening the external contact between Pins 4-5 of the
alarmsconnector).Byopeningthisdigitalinput,allloadsareshuto󰀨andthealarmrelayDO1 switches (between Pins 1-2-3 of the alarms connector). The
operator then recloses the digital input IN4 and the regulator exits the testing sequence.
