9.1.4 Setting

9.1.4.1

"Setting" mode

- 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

Defining first position (0% or 100%)

(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

Defining second position (0% or 100%)

- 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

Saving the settings

- 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 ad-

justment procedure with a wider range (min. positioning travel).

(See positioning travel specification on actuator ID label)

9.1.4.5

Correction after setup

- 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.

9.2 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.

A conductive ground connection is established between the PC and the CONTRAC electronics with the

RS 232 communication cable. If the PC is grounded, this may cause a ground loop in the installation.

9.3 Functions and signals at the LCP

Change-over to adjustment mode:

Press and hold both drive buttons for approx. 5

seconds

Moving to an end position

Use associated drive button on LCP

Saving the first end position

Press button 0% or 100%

Saving the second end position

Press button 0% or 100%

Confirm settings

Press 0% and 100% buttons simultaneously

Normal operation: MAN / AUT

Driving with button on CSF

Priority over control system

Electronic is in bootstrap mode during the data trans-

fer of e. g. firmware, objects or motor charcteristics;

use ECOM688 software for this procedure.

Function

Adjustment

Bootstrap mode

Fault (both LEDs flash alternately at 4Hz)

Both LEDs flash synchronously at approx 4Hz

after time has expired.

Both LEDs continue to flash at 4Hz while driv-

ing.

The associated LED flashes at approx. 2Hz,

the other continues at 4Hz.

The associated LED flashes at approx. 2Hz

synchronously to the first one.

Both LEDs are briefly „ON" together and then

extinguish.

Operation

LED off

Both LED are „ON"; actuator is not available

If no „Failure" conditions exist, both LEDs

extinguish (if the actuator had been moved out

of its operating range, drive it back prior to the

reset).
