5.4 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.

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
triggers a
pushing on its lever.
Cams orientation are factory
pre-set, yet you can still
re-adjust them
during the commissioning
if necessary.
