In order to carry out the operations described for the K1 or K2 key in the Table 5, it is necessary to
turn the proper SW1 switch key ON, press a proper momentary switch (Reset µP1 or Reset µP2) and
after about 30 seconds, turn the SW1 switch key back to the OFF position.
Note:
Turning the key 1 of the switch ON and restarting the PSC-49 module results in deleting the previous
system configuration and loading the standard configuration in this place.
Leaving the keys 1, 2 and 3 in the ON position may result in losing the entered data (signalled as a
fault).
