5 Initialization

5.1 Initialization procedure

Initialization sets the limit stop points for the
position feedback of the actuator. This process is
done automatically, by the Module, however , the
user must start it and the unit must be wired
according chapter 4.

WARNING:

* During the initialization routine the actuator /valve
combination will cycle several times.
* Before initialization check whether the actuator
and valve have the same “Open” and “Closed”
positions (see Chapter 4 of Installation & Operation
Manuals FieldQ-series Pneumatic Actuators,
DOC.IOM.Q.E)
* Ensure that the valve stroke is not obstructed
before the initialization routine is started.

5.2 Start initialization procedure (see

figure 9)

1 Push "Open" and "Closed" reassignment
buttons at the same time for 4 seconds.
2 Status LED will blink.
3 Actuator will cycle 2 or 3 times.
4 At the end of the routine the Status LED
switches to constant on, meaning the initializa-
tion was successful.
5 Check that the actual valve position (open or
closed), is indicated on the button board.

5.3 Troubleshooting

5.3.1 If auto initialization procedure has failed
(Status LED is flashing):
1 Check supply pressure
2 Check Actuator assembly code (see Installa-
tion & Operation Manual FieldQ Valve
Actuator DOC.IOM.Q.E)
3 Repeat auto initialization routine
4 When the actuator does not move within 10
seconds, the auto initialization will fail.
5 To solve this either;
- perform the “default setting” procedure (see
§5.3.5) and repeat the initialization proce-
dure (see §5.2), or
- set manually the limit switch points (see
§5.3.4).
5.3.2 If the position feedback on the button board
is reversed:
1 Check if the actuator is correctly mounted to the
valve, if yes:
2 Push the button, corresponding with the actual
position of the actuator, for 3 seconds (“Open”
or “Closed”).
3 The corresponding LED starts flashing.
4 Release the button and push again until LED
burns constantly, Status LED indicates “init
successful”.
5 The feedback of the opposite position changes
automatically.
