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
switched to 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
Programmable parameters are shown in succession. After
one pass, the device is fully programmed.
In each case the first shown item is the factory preset.
1. Description
