5.3.3 If readjustment of the positions is needed
without cycling the actuator:
After adjusting the mechanical limit stops on the
actuator, in such a way that the switch points are
not reached (i.e. reducing the stroke), the Module
will not give proper position feedback.
The easiest way of readjustment of the exact
positions is performing the initialization procedure
(see §5.2).
During initialization the actuator will cycle 2 or 3
times. When it is not allowed that the actuator/
valve unit cycles, the new switch point can be set
with the following procedure:
Table 1. LED indications
Status
OK (Init successful)
Initializing
Init error
Init default
Waiting for
reassignment confirm
Identification
Table 2 Button board functionality
Action
Set to factory default
Initialize
Reassignment "Open" end position
Reassignment "Close" end position
DOC.IG.QC01.1 Rev.: B
Status LED action Open/Close LED action
Constant on Normal operation (position indicated by LED which is constant on)
Blinking (see fig. 9) Normal operation
Flashing (see fig. 9) Normal operation
Flashing (see fig. 9) Activated LED (depending on position) blinking
Constant on Activated by push button LED Flashing, other LED is off
Flashing for 300 sec Normal operation
Reassignment buttons
Push both buttons before power up, and than hold until Status LED is constant
on. Release and observe LEDs to indicate default
While powered up push both buttons until Status LED starts blinking
Push "Open" button until "Open" LED starts flashing, release button and push
again until LED is constant on, Status LED indicates "init successful".
Push "Close" button until "Close" LED starts flashing, release button and push
again until LED is constant on, Status LED indicates "init successful".
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".
