2. Inputs
INP
Dynamic count input. Max. count frequency 30 Hz or
10 kHz programmable via set up
RESET
Dynamic reset input. Linked to the red reset key.
3. Settingofthe operating parameters
a. Hold down keys on front panel and switch on the
supplyvoltage.
b. The display shows
c. After releasing the keys the display alternates
between menu title and corresponding menu item at
a frequency of 0.5 Hz. After any key is pressed
down, only the menu item is displayed.
d. Pressing the right key, the menu item will be
switchedto next value.
e. Hold down the left key and press the right key to
enter and switch to the next menu title.
f. After programming the last menu item, the
programming routine will be left and the new values
will be stored by switching the menu item to „YES“.
If you chose „NO“, the programming routine will be
passed through once again.
4. Programming routine
Programmableparametersare shown in succession.
After one pass, the device is fully programmed.
In each case the first shown item is the factory preset.
