Setting
9.1.4.1
- Set electronics to "setting" mode by pressing both push buttons (3) simultaneously for approx. 5
seconds, until both LEDs (2 + 8) are flashing synchronously at approx. 4Hz. („setting mode" is the
standard electronic unit status after passing the final factory test)
9.1.4.2
IMPORTANT (Higher precision in 2nd position)
- Move to desired position by pressing one of the push buttons (3).
- To accept the position for 0% or 100%, press push button (10) or (9); the associated LED flashes
at approx. 2 Hz when value is correctly accepted, the other one continues to flash at approx. 4Hz
9.1.4.3
- Move to second position by pressing tho other of the push buttons (3).
- To accept the position, press push button (10) or (9); both LEDs (2) and (8) are flashing at approx.
2 Hz when values are accepted correctly.
9.1.4.4
- Save the settings by simultaneously and shortly pressing the push buttons (10 + 9); the LEDs (2 +
8) are „ON" (without flashing) for approx. 5 sec before they extinguish and the setting procedure is
completed.
- If the selected range is too small for the actuator, both LEDs will flash again at 4Hz. Repeat the
adjustment procedure with a wider range (min. positioning travel).
(See positioning travel specification on actuator ID label)
9.1.4.5
- If the setting is to be corrected after accepting the first value, first press the Reset button (4) and
then repeat the setting.
- If the correction is to be re-done after saving the settings, the entire adjustment procedure must
be repeated.

Adjustment using the configuration program
Context-sensitive help information is available in the configuration program at all times. For basic han-
dling and installation instructions refer to the associated manual, number 41/68-001.
WARNING
A conductive ground connection is established between the PC and the CONTRAC electronic unit
with the RS 232 communication cable. If the PC is grounded, this may cause a ground loop within the
installation.
