    3. General Proper Use Power electronic units EBN853 and EBN861 may be used exlusively for triggering electrical actuators of the RSDE... or RHDE ... series. Do not use them for any other purpose. Otherwise, a hazard of per- sonal injury or of damage to or impairment of the operational reliability of the device may arise.

  • Page 13: Setup

    10.Setup The actuator only requires the basic settings (adaptation to the operating range) in order to be operated with the standard or custumer specific configuration. Use the Local Control Panel (LCP) for these set- tings. Use the appropriate configuration software for more detailed parameter changes or diagnosis functions.

  • Page 14: Adjustment Using The Configuration Program

    10.1.4Setting 10.1.4.1 “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) 10.1.4.2 Defining first position (0% or 100%) (Higher precision in 2nd position) - Move to desired position by pressing one of the push buttons (3).
