Change length of stroke
The stroke is set to 4,3 mm when delivered
from the factory. This can be changed to 3,2
mm or 6,0 mm, if used together with a valve
from a different manufacturer than the one
described in this manual. It can be changed by
moving the jumper as follows:
Wiring
All electrical connections must be made by a
qualied electrician
NOTE!
If the actuator has been powered up, check
that the drive rod within the actuator is in
its innermost position before the actuator is
mounted on the valve.
Alternatively, use dipswitch no. 4, if it is set to
Reverse Action, ensure that FC calls for heat.
Mounting
The actuator is mounted on the valve when the
power supply is disconnected.
