Key:
Param et er:
The black square
represents the factory
setting assignment
(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 us t be as s igned to one of the analog inputs AI1 to AI3, to the puls e input, according to
whether any extens ion cards have been ins erted.
PID reference:
The PID reference m us t be as s igned to the following param eters: Pres et references via logic inputs ( rP2 ,
rP3 , rP4 )
In accordance with the configuration of [Act. internal PID ref.] (PII) page 210 :
Internal reference ( rPI ) or
Reference A (
[Ref.1 channel]
(Fr1) or
[Ref.1B channel]
(Fr1b) , s ee page 154 ).
