Status input 1
Alarm input from rotary encoder. Internally connected to 5 V via pull-up.
Switching to negative potential, i.e. connection to GND leads to error bit and
LED display. If externally supplied (not recommended) 5 V max. against GND is
permitted.

Meaning
INPUT A, B, C green
indicates TRUE level
INPUT 1
red
is lit, if INPUT 1 is connected to GND
[INPUT 1 is connected to an internal 5 V HIGH level though internal pull-up
(default)]
LATCH
green
is lit, if a signal (+24 V) is connected to the latch input
GATE
green
is lit, if a signal (+24 V) is connected to the gate input
