3. General 3.1 Proper use Linear actuators for continuous positioning are intended to be used exclusively for actuating final con- trol elements (valves, vanes, etc.). Do not use these actuators for any other purpose. Otherwise, a ha- zard of personal injury or of damage to or impairment of the operational reliability of the device may arise. -

6. Assemblies (not shown) Fig. 1: Basic design of RSD .. 6.1 Standard operation The motor (1) triggered by the power electronics controls the axially fixed drive sleeve /nut assembly via oil-lubricated spur gears. A ball bearing screw (see Figure 2) radially fixed by an anti-twist arrester converts the rotary motion to a linear one. -

9. Mounting 9.1 Actuator check Prior to mounting the actuator please verify if the device has been delivered in the configuration spec- ified in your order and if it is suitable for the intended purpose. Check: - if the positioning travel is sufficient for the valve stroke - if it is filled with the proper oil type, see section 8.2 or oil label on actuator for details. -

9.5 Mounting the actuator to the valve - Completely retract the actuator thrust rod and put the actuator on the valve yoke. - Make sure the valve stem is centrically aligned with the bore and at right angles to the actuator seat (permissible parallel deviation <... -
Page 11: Electrical Connection
10. Electrical Connection Each actuator requires a Contrac electronic unit. Proper actuator operation requires an actuator spe- cific software loaded in the associated electronic unit. See electronic unit instructions for details. Com- pare the data labels on both, electronic unit and actuator, in order to ensure a correct hardware and software assignment. -

Page 13: Setup
11.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. -

11.1.4Setting 11.1.4.1 “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) 11.1.4.2 Defining first position (0% or 100%) (Higher precision in 2nd position) - Move to desired position by pressing one of the push buttons (3). -
Page 15: Maintenance
12. Maintenance Linear actuators of the RSD... series feature a robust design. As a result, they are highly reliable and require only little maintenance. The maintenance intervals depend upon the effective load and are therefore not specified here. The built-in microprocessor evaluates the actual load factors (e.g. torques, temperatures, etc.) and de- rives the remaining operating time until the next routine maintenance is required. - Page 16 12.3.2 Mounting The toothed gear pair of the position sensor is held in place by a tension spring (3), to ensure sufficient free motion when the direction of rotation is reversed. - fasten sensor cable plug on sensor pcb - set the stop pin to the center position, as shown in Figure 14 - align the sensor and its gears with the actuator;...
