Heating element
Each actuator includes a heating resistor.
As soon as the actuator is installed in the field, it is recommended
to power the resistor to prevent condensation.
•
Immediately put the cover back in place after start-up while
ensuring its seal is clean. Never leave actuator electrical
components without their protection cover.
In case of water intrusion:
•
Dry electrical components before putting back the cover.
•
Check electrical insulation.
6 TRAVEL LIMIT SETTINGS
The actuator is factory-set for a 90°travel.
It features 2 devices to limit the travel:
•
Cams trigger switches to switch off power at an end position or
to signal a position
•
Mechanical stops mechanically block rotation to protect the valve
in case of over-travel.
They must not be used as travel limits.
Single cam setting
The cam rotates with the
output shaft and
triggers a switch by
pushing on its lever.
Cams orientation are factory
pre-set, yet you can still
re-adjust them
during the
commissioning
if
necessary.
