3.1.5 Torque Control
Torque sensor which detects the variation of torque during operation is installed for preventing damage of valve
and actuator under overload condition. Once actuator is under overload, torque sensor is tripped and actuator
stopped immediately
(This is standard when the actuator is fitted with PCU & is an option of on/off control)
3.1.6 Manual Override
Caution
Ensure power is isolated before the manual override is engaged.
The manual override lever must be dis-engaged before power is applied to the actuator.
Failure to do so will end in motor burnout.
Gently oscillate the handwheel while engaging & disengaging the manual override lever.
The lever in vertical position = Engaged
The lever in horizontal position = Dis-engaged
3.1.7 Lubrication
HQ-005 electric actuator is a totally enclosed unit with permanent lubricated gear train (Moly EP Grease). Once
installed, further lubrication should not be required. However, periodic preventative maintenance will extend
the operating life of the actuator.
