9. Commissioning (basic settings)
1. Set selector switch to position 0 (OFF).
Information: The selector switch is not a mains switch.When positioned to 0
(OFF), the actuator cannot be operated.The controls' power supply is
maintained.
2. Switch on the power supply.
Information:Please consider the heat-up time for ambient temperatures below
–20 °C.
3. Perform basic settings.
9.1 Heat-up time for low temperature version
Please note that for low temperature versions, the controls require a heat-up time.
This heat-up time is applicable in case the actuator and the controls are not live and
have cooled down to ambient temperature. Under these conditions and after
connection to the voltage supply, the following heat-up times must be complied with
prior to commissioning:
For –40 °C = 30 min.
For –50 °C = 60 min.
For –60 °C = 100 min.

9.2 End stops in part-turn actuator
The internal end stops limit the swing angle.They protect the valve in the event of
limit switching failure.
End stop setting is generally performed by the valve manufacturer prior to installing
the valve into the pipework.
