Choice of PNP or NPN The contacts 7 to 10 are comparator signal inputs.
Max. rating
150 VA/30 W
The user must take care that, in case of disturbance, the contact
rating of 8 A / 150 VA (W) is not exceeded. Internal spark suppressi-
on by means of zinc-oxide varistor (275 V). The output relays of the
instrument (1 relay or several) may in total switch 5 x per minute at
the most. Admissible clicks according to interference suppression
standard for the industrial sector. In case of higher switching rate,
the operator will be responsible to take care of local interference
suppression in consideration of the contact rating.
3.3 Assignment of 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.
The type of output, as momentary or latched signal, can be chosen
3
in the programming lines 41/42.
Their function, as normally open or closed, is selected in program-
ming line 40.
Max. switching
voltage
+40 VDC
The electronic outputs are not short-circuit-proof.
3.4 Assignment of signal inputs
They can be triggered either by PNP or NPN sensors. The input logic
as well as the operating threshold are correspondingly chosen in pro-
gramming line 33.
The contacts 7 (Track A) and 8 (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 31 and 32.
The contacts 9 and 10 are 2 control inputs for Reset, Stop, Hold,
Print, Keylock etc. The function of these control inputs is selected in
the programming lines 34 and 36.
The minimum pulse duration of control input 1 can be switched in
programming line 35 from 30 ms to 100 μs. For control input 2, 30
ms are generally valid.
