Motorized Rotary Actuator
7.5 Commissioning
7.5.1 Quick start guide
1. Set DIP switches
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.
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 26
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 first 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.)
