3.3 Assignment signal input
Choice of PNP or NPN The contacts 9 to 12 are comparator signal inputs.
They can be triggered either by PNP or NPN encoders. The input
logic as well as the operating threshold are correspondingly chosen
in programming line 28. The contacts 9 (Track A) and 10 (Track B) are
counting inputs for a counting range between 3 Hz, 25 Hz or 10 kHz.
The counting rate is determined in programming lines 26 and 27.
The contacts 11 and 12 are 2 control inputs for Reset, Stop, Hold,
Print, Keylock, etc. The function of these control inputs is selected in
the programming lines 29 and 31
