6.6. Up-/Downwards counter (TTL, switching-contact)
The upwards counter starts counting upwards from 0 according to its settings. The downwards
counter starts counting downwards from the upper value that had been selected.
The current value of the counter can be reset anytime by connecting pin 8 to GND (e.g. pin 7).
The counter starts from its beginning as you disconnect pin 8 and pin 7.
Feature:
The present counter value won‘t be lost if the voltage supply is disconnected. The counter
starts from this value after restarting.
This chapter describes how to configure the device as a counter.
This instruction demands that you selected “
Co.up
“ or “
Co.dn
“ as input type like it is explained in
chapter 6.1.
The display must show

NPN
Switching contact, NPN
For direct connection of a passive switching contact (e.g. push
button, relay) or transmitter with NPN output.
There is a internal pull-up-resistor.
PNP
Switching contact, PNP
For direct connection of a transmitter with PNP output.
There is a internal pull-down-resistor.

POS
The counter is triggered on the positive (rising) edge.
NEG
The counter is triggered on the negative (falling) edge.

OFF
Exceeding of the counter range is tolerable until you reach the
maximum measuring range limit.
ON.ER
The measuring range is exactly bounded by the selected counter-
range-limit. When exceeding or short falling of the limit the device
will display an error message.
ON.RG
The measuring range is exactly bounded by the selected counter-
range-limit. When exceeding or short falling of the limit the device
will display the upper counter-range-limit or 0.
