6. Functions of the keypad and of external inputs
6.1 Reset
For setting the actual value to zero:
Use the external input

, and connect resp. close it for a short time to + 24 V to re-
set the actual value.
Please note:
The external input is a statically input and is active, when it’s connected with
+ 24 V. If the input remains constantly in connected state, the display remains “0” and no
counting is possible.
For this a push-button without self-holding is recommend.

dure starts from this point then. After renewed pressing of
