Choics of PNP or NPN The contacts 7 to 11 are comparator signal inputs.
The user must take care that, in case of disturbance, the contact
rating of 8 A / 150 VA (W) is not exceeded. The output relay of the
instrument (1 relay or more) may, in total, switch max. 5 x per mi-
nute. Admissible clicks as per interference suppression standards
EN 61000-6-4 for the industrial sector. In case of higher switching
rate, the user is responsible for and in charge of providing interfe-
rence protection on site in consideration of the load to be switched.

Assignment signal outputs (electronic)
The electronic outputs (contacts 3, 4 and 5, 6) are optocoupler
outputs. The signal outputs can be assigned as per the adjacent
terminal diagram. Their function, as normally open or closed, is
selected in programming line 40. The limit values are assigned in
3
lines 47 and 48 of the program.

The electronic outputs are not short-circuit-proof.

Assignment signal inputs
They can be triggered either by PNP or NPN encoders. The input lo-
gic as well as the operating threshold are correspondingly chosen in
programming line 33.
Contact 7 triggers the batch counter. The counting rate (3 Hz, 25 Hz
or 10 kHz ) is chosen in programming line 32. Contact 8 triggers the
tachometer. The frequency range of 25 Hz or 40 kHz is determined
on programming line 31. The contacts 9, 10 and 11 are control in-
puts for Hold, Programming Disabled, Batch counter Reset, etc. The
function of these control inputs is selected in the programming lines
34, 36 and 37 . The minimum pulse duration of control input 1 can be
switched in programming line 35 from 30 ms to 100 μs. For control
inputs 2 and 3, 30 ms are generally valid.
