The F02 unit can be installed onto the valve in two different ways:
Direct mounting: insert the valve shaft into the actuator bottom flange,
taking care to correctly connect the insert. Fix the screws on the
valve flange to the actuator coupling block.
Bracket mounting: install the bracket and the adapter onto the valve; then insert the
valve shaft into the actuator bottom flange, taking care to correctly
connect the insert.
Fix the screws between the bracket and the valve flange and the
actuator coupling block.
4.5 Manual operation
F02 electric actuators are supplied with a handwheel for manual override as standard, to
operate the actuator in case of power supply failure or during setting.
The handwheel is always engaged. For safe operation, the handwheel does not rotate
during electric operation.
Turn the handwheel clockwise to close and counter-clockwise to open.
During manual operation, check the actuator manoeuvre on the local mechanical indicator.
Warning: Do not manually operate the actuator with devices other than
the handwheel. Using cheater bars, wheel wrenches, pipe
wrenches, or other such devices on the actuator handwheel
may cause serious personal injury and/or damage to the
actuator or valve.
Important: Handwheel rotation
In standard applications clockwise rotation of the handwheel
moves the valve to close position and counter-clockwise
rotation moves the valve to open position.
Different operation must be clearly indicated on the
handwheel.
