Motorized Rotary Actuator baelz 375-E42 7.5 Commissioning 7.5.1 Quick start guide ↑ 1. Set DIP switches 2. Connect to supply 3. Start initialization run 7.5.2 Initialization run If the unit is not initialized, the green LED flashes. The red LED is lit when the position of the potentiometer is not ideal for an initialization run. (See section 7.5.3 for meaning of LED signals.) An initialization run can still be carried out, but it will take approx. 1x valve travel time longer. During a successful initialization run, the actuator is moved to both of its end positions. The potentiometer and the position of the actuator are synchronized and values for actuator travel time and switching hysteresis are determined. -
