2. Inputs

INP

Dynamic count input. Max. count frequency 30 Hz or
10 kHz programmable via set up

RESET

Dynamic reset input. Link ed to the red reset ke y.

3. Setting of the operating parameters

a . Hold down keys on front panel and s witch on the

supply voltage.

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 k e y is pressed
down, only the menu item is display ed.

d . Pressing the right key, the menu item will be

switched to ne xt value .

e . Hold down the left key and press the right k ey to

enter and switch to the next men u 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 r outine

Programmable parameters are sho wn in succession.
After one pass, the device is fully progr ammed.

In each case the first shown item is the factory preset.
