Operation

6 Operation
Immediately after completing mounting and
start-up, the valve with electric actuator is
ready for use.
WARNING
!
Form-fit version: crush hazard arising from
moving parts (actuator and plug stem).
Do not insert hands or finger into the yoke
while the valve is in operation.
NOTICE
!
Form-fit version: operation disturbed by a
blocked actuator or plug stem.
Do not impede the movement of the actuator
or plug stem by inserting objects into their
path.
Operating keys are used to operate the elec-
tric actuator with process controller (see Fig.
1). Various operating functions can be set at
the actuator.
NOTICE
!
Unwanted function after pressing the operat-
ing keys due to incorrect configuration.
The function of the keys depends on how the
electric actuator with process controller is
configured.
Before performing an operating action,
check the necessary configuration (see sec-
tions 6.1 to 6.5).

6.1 Adjusting the set point

Necessary configuration (see section 10.2)
− A2.1 = 1 to change the set point at con-
troller [1] C1.SP
− A2.1 = 2 to change the set point at con-
troller [2] C2.SP
Adjusting the set point
Select the set point reading.
Start set point adjustment.
Raise/lower the set point.
After five seconds the reading
changes back to the reading deter-
mined in A3.1. The actuator uses
the newly adjusted set point for
closed-loop control.
If '==' is selected instead of the
value, the set point limit is
reached. In this case, the set point
adjustment is canceled without
changing the set point.
Canceling set point adjustment
or until '==' appears.
After five seconds the reading changes
back to the reading determined in A3.1
without the set point being changed.
6.2 Starting/end closed-loop
operation
Necessary configuration (see section 10.2)
− A1.1 = 1
