Page 10: Principle Of Operation
Motorized Linear Actuator baelz 373-E45 4.3 Principle of operation Motorized linear actuators to operate control valves for fl ow regulation applications in control and process technology. The self-locking threaded spindle/spindle nut is driven by an electric motor via a gearbox. This converts the rotary movement into a linear movement. Load- dependent limit switches dictate the end positions 4.3.1 Manual adjustment Manual adjustment may only be carried out when the motor is not in motion. For the adjustment, unscrew the cap nut from the top of the cover, remove the hand crank from the bracket on the bottom of the actuator housing and insert it into the tube in the top of the cover. Turn the crank handle using gentle pressure. W. Baelz & Sohn GmbH & Co. · Koepffstrasse 5 · 74076 Heilbronn · Germany · www.baelz.de Seite | Page 10 |... -

Motorized Linear Actuator baelz 373-E45 6.2 Adjusting the potentiometer assembly 1. The potentiometer can be set to the defined zero point using the screw slot on the rear (for normal mode clockwise up to the mechanical stop). For valve stroke < 44 mm, note that for reverse mode, the potentiometer must be turned to the new zero point (mechanical stop opposite). For this adjustment the actuator spindle must be in the correct end position: Normal mode: zero point = spindle extended --> potentiometer fully clockwise Reverse mode: zero point = spindle retracted --> potentiometer fully anticlockwise 2. The additional limit switches can be adjusted by loosening and retightening the knurled nut and setting the contact washers to the desired positon. Fig. 5: Adjusting the potentiometer assembly W.

Start initialization run 8.5.2 Initialization run If the unit is not initialized, the green LED fl ashes. The red LED is lit when the position of the potentiometer is not ideal for an initialization run. (See section 8.5.3 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 valve is moved to both of its end positions. The potentiometer and the position of the valve are synchronized and values for valve travel time and switching hysteresis are determined. Switch DIP switch 12 from 0 to 1 to start an initialization run. The red LED is lit during initialization. When initialization has been successfully completed, only the green LED is lit. For error signals see table in section "Errors after an initilization run", page 27 As long as DIP switch 12 is set to 1, errors and alarms occurring during normal positioner operation will not be shown. This enables errors occurring during initialization to be distinguished from errors during normal positioner operation. Switch DIP 12 back to 0 after the initialization run to show any errors occurring in normal positioner operation on the red LED. (After the fi rst initialization run (unit not previously initialized), the unit moves to the 50% position upon completion of initialization. As soon as DIP 12 is set to 0, the baelz 7020A will follow the set value signal at analogue input 2.) W. -
