INSTALLATION TIP:
Always issue a soft reset after connecting the Optima and XNX for the rst time. The
soft reset is performed by accessing the XNX calibration menu.
NOTE:
When the soft reset is initiated for the Optima IR Sensor, the RS-485
communication will be interrupted temporarily and faults F120 and/or
F161 may be observed. RS-485 communication will be re-established
in a few minutes and the faults will be reset automatically in the Non-
Latching Mode. The faults must be reset manually in the Latching Mode.
