2. General 2.1 Proper use The actuators are intended to be used exclusively for actuating final control elements (valves, vanes, etc.). Do not use these actuators for any other purpose. Otherwise, a hazard of personal injury or of damage to or impairment of the operational reliability of the device may arise. -

Page 12: Setup
Setup The basic settings (definition of end positions) can be made via the Local Control Panel (LCP). It is used for adapting the actuator to the operating range and the effective di- rection without a PC. The actuator can be set up and configured completely using the appropriate configuration program. -

10.1.3.1 “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. 10.1.3.2 Defining first position (0% or 100%) Move to desired position by pressing one push button (3). (Higher precision in 2nd To accept the position, press push button (10) or (9);... -
Page 14: Maintenance
11. Maintenance Contrac actuators have a robust construction. As a result, they are highly reliable and require only little maintenance. The maintenance intervals depend upon the ef- fective load and are therefore not specified here. The built-in microprocessor evaluates the actual load factors (e.g. torques, temper- atures, etc.) and derives the remaining operating time until the next routine mainte- nance is required. - Page 15 11.3.2 Mounting The toothed gear pair of the position sensor is held in place by a tension spring (3), to ensure backlash-free motion when the direction of rotation is reversed. - set the stop pin to the center position, as shown in Figure 14. - align the sensor and its gears with the actuator;...
