Param et er:
The black square

(1) Ramp AC2 is only active w hen the PID function starts up and during PID "w ake-ups".
PID feedback:
The PID feedback m ust be as s igned to one of the analog inputs AI1 to AI3, to the pulse input, according to
whether any extens ion cards have been inserted.
PID reference:
The PID reference m us t be as signed to the following param eters: Pres et references via logic inputs
(rP2,
rP3, rP4)
