Safety notes
- 6 -
Maintenance and repair work may only be performed by qualified personnel. When wiring
electrical equipment the applicable VDE and EVU regulations are observed.
Electrical protection measures (grounding resistance, etc.) are to be checked.
When working on the actuator or connected to these devices and system components, the supply
voltage must be switched off.
Perform the installation, repair work in compliance with the applicable statutory and professional
safety and accident prevention regulations!
The safety aspects are always depending on the circumstances and the timing of the assembly,
disassembly, adjustment, commissioning and are therefore always to adapt to the application.
Mounting
These safety instructions are to be considered by any person concerned with the operation,
maintenance or repair of the actuators. The proper and safe operation requires proper
transport, proper storage, mounting and careful operation.
Does the actuator the required version ( torque, protection, voltage, swivel angle, etc.).
Does the wiring acc. to the voltage (see diagram/type label).
Is it possible to adjust the valve on the manual override.
Switch from AUTO to MAN, move the handwheel/ handlever to synchronize the
transmission then exit the adjustment path manually and turn back to the starting
position. Then switch from MAN to AUTO and move the handlever/ hand wheel
onesmore.
Switch off all equipment, machinery, equipment which is affected by the installation or repair and
disconnect the equipment, machinery, plant, where appropriate, from the net!
Check whether the plant shut-down causes potential danger ! Inform the shift foreman, safety
engineer or the conductor immediately to prevent a fault in the actuator, by run out or spilling of
liquids or leakage of gases, with suitable measures!
Check the correct function of the safety devices (e.g. Emergency-Stop-Switch/Safety valves
etc.) !
Provide for adequate vibration isolation! Vibrations can cause damage depending on the type or
resonance with the actuator components. Be particularly sensitive to wearing parts such as
potentiometers, motors or electronic components. The use in vibration-prone environments has
to be coordinated with the actuator manufacturer.
When installed in wet environments and in areas with significant temperature changes in each
case the built-in control room heater has to be kept actively after the actuator is stopping in the
end position.
Fireplaces, stoves, direct sunlight and other heat sources can emit large amounts of energy.
This heat radiation should be avoided by appropriate shielding of the actuator.
