English This actuator includes a compressed spiral spring which can only be disassembled with special tools. Only the control compartment remains accessible without having to use special tools (see picture). Flange on FQ30 and FQ50 models 1.3 MANUAL OPERATING CLUTCHING (EXCEPT FOR FQ04 AND FQ08) FQ-range actuators are fitted with a handwheel (except for the FQ04 and FQ08). - Page 8 English 1.3.1 To clutch the manual control 1. If a padlock locks the clutch lever, remove it from the rod. 2. Tilt the clutch lever to operate the actuator with the handwheel, refer to the figure below. When the clutch lever is in its lowered position the manual control is engaged, therefore the safety spring return is not operational and fail-safe action is not available.

Page 10: Commissioning
English 3 COMMISSIONING 3.1 TRAVEL LIMITS SETTING When the power supply is OFF and the clutch lever is up, the actuator and valve sit on their fail-safe position, which is the resting position of the returning spring. The mechanical stops limit the end of travel in fail-safe operation. The cams limit the end of travel in normal operation. - Page 11 English 3.1.2 Setting travel limits for normal operation Do not electrically stop the actuator on mechanical stop, it may cause damage. Required tools: Flat-blade screwdriver, Hexagonal key. To set a cam: 1. Insert screwdriver in the slit of the setting head of the cam.
- Page 12 English To set cams and mechanical stop at the opposite end 1. On the opposite mechanical stop, block screw (a) with hex. key and unblock counter nut (b) with open-end wrench. 2. Unscrew the screw (a) of a few milimeters with hex. key. 3.
