Connecting of a transducer (with individual power supply)
Connecting of a transducer (without individual power supply)
PNP output with external resistor wiring.
PNP output and external resistor wiring.
Hint: Rv2 = 600_, Rv1 = 1.8k_ (with power supply voltage = 12V) or 4.2k_ (with power supply voltage = 24V), device config.: Sens = TTL
(Rv1 is a current limiting resistor and may be shorted if necessary. It should never exceed the mentioned value.)
3.3.7. Connecting a counter signal
When configuring the device you can select 3 different input signal modes similar to the connetion of
frequency- and rotation-signals. The connection of a sensor-signal for a counter-signal is the same used
for the frequency- and rotation-signal.
Please use the wiring diagram given below.
There is the possibility to reset the counter. When connecting contact 8 with GND (e.g. contact 7) the
counter will be reset. You can do this manually (e.g. with the help of a push-button) or automatically
(with one switching output of the device).
Hint:
When connecting the device, take care not to exceed the limits of the input-voltage or the input-
current of the frequency input.
manually reset the device with the help of a push-button
automatically resetting with the help of output 2 and
additional resetting the device via push-button
Hint: Output 2 has to be configured as NPN output
Cascading of EV-94 EB`s
Hint for EV-94 EB:
Device 1 – Input signal like impuls-transmitter,
Output 2 configured as NPN output
Device 2 – Input-signal = switching-contact
