Description C)
Humidity demand is given out from the process controller types DICON 1000/1001 (= D2 and PD2) as
a binary signal 0V or 24V to the control side of the two solid state relays for the electrode current path
(see wiring diagram KBF).
0V = no humidity demand
24V = steam production necessary
The binary signal is taken there and gets via plug connector HLR + and – to the BINDER humidity
board.
The Binder Humidity Board switches +24V on plug connector SPS I 0.0 as message for the SPS that
there is a humidity demand.
