Operation
Safety instructions
DANGER
Danger to life due to unexpected movement of the actuator!
Unexpected movement of the actuator may lead to very
serious injuries or to death.
• Make sure that the actuator can move without posing a
danger to people!
WARNING
Risk of crushing between the lever and the stops or between
the lever and the link rod, respectively!
• Do not reach into the danger zone.
• Start up the actuator with installed lever cover only.
Note
Positioning loop monitoring in the electronic unit must always
be active, it is set as default at the factory and cannot be
deactivated nor changed afterwards.
• Before power-up, make sure that the ambient conditions
specified in the data sheet are complied with and that the
power supply corresponds with the information specified on
the name plate of the electronic unit.
• If it can be assumed that safe operation is no longer
possible, take the unit out of operation and secure against
unintended startup.
• When the actuator is installed in work or traffic areas that
may be accessed by unauthorized persons, the operator
must put appropriate protective measures in place.
• Switch off the power supply to the motor before handwheel
operation.
Automatic mode / Handwheel mode
WARNING
Risk of injury due to live parts!
Risk of death or serious injuries due to electricity and
unexpected machine movements. In automatic mode the
motor is always under power, even at standstill.
• When working on the actuator or the related subassembly,
switch off the supply voltage for the electronic unit and
separate anti-condensation heater (option), and take
precautions to prevent unintentional switch-on.
The motor controlled by the electronic unit controls the output
shaft via the oil-lubricated gearing. This transmits the rated
torque to the valve via a lever with ball-and-socket joints and a
coupling rod. The position sensor detects backlash-free the
current position of the output drive shaft.
Adjustable limit stops prevent overloading of the valve in the
event of an operating error. The brake integrated in the motor
carries out the stop function if the supply voltage is switched
off.
Manual operation
Handwheel mode allows you to move the actuator when the
supply voltage is switched off.
CAUTION
Risk of injury!
Risk of injury due to unexpected movement of the handwheel.
When pressing the handwheel unlock, the handwheel can
unexpectedly move due to the reset force of the valve.
• Hold the handwheel in place with your free hand when
pressing the handwheel unlock.
1.
Press the handwheel unlocking catch.
Note
When the handwheel is turned to the right, this causes a left turn
of the driver lever (rotating direction with view to the handwheel
shaft or output drive shaft).
2.
Turn the hand wheel to move the actuator lever to the
desired position.
3.
Release the unlocking catch.
