09 SAFETY NOTES
HANDBOOK_89
First check the following circumstances:
- Does the actuator the required version ( torque, protecon, 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 adjust-
ment path manually and turn back to the starng posion. Then switch from MAN to AUTO and move the handlever/
hand wheel onesmore.
These safety instrucons are to be considered by any person concerned with the operaon, maintenance or repair of
the actuators. The proper and safe operaon requires proper transport, proper storage, mounng and careful operaon.
- Maintenance and repair work may only be performed by qualified personnel. When wiring electrical equipment the
applicable VDE and EVU regulaons are observed.
- Electrical protecon 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 installaon, repair work in compliance with the applicable statutory and professional safety and accident
prevenon regulaons!
- The safety aspects are always depending on the circumstances and the ming of the assembly, disassembly, adjust-
ment, commissioning and are therefore always to adapt to the applicaon.
Mounng:
- Switch off all equipment, machinery, equipment which is affected by the installaon or repair and disconnect the
equipment, machinery, plant, where appropriate, from the net!
Check whether the plant shut-down causes potenal danger ! Inform the shi 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 funcon of the safety devices (e.g. Emergency-Stop-Switch/Safety valves etc.)!
- Provide for adequate vibraon isolaon! Vibraons can cause damage depending on the type or resonance with the
actuator components. Be parcularly sensive to wearing parts such as potenometers, motors or electronic
components. The use in vibraon-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 acvely aer the actuator is stopping in the end posion.
- Fireplaces, stoves, direct sunlight and other heat sources can emit large amounts of energy.
This heat radiaon should be avoided by appropriate shielding of the actuator.
Seng and Commissioning:
- Make sure that the starng or the test sengs on the actuator, no potenal hazards to personnel or the environment.
- If necessary, set up warning signs, so that unintenonal operaon is prevented.
- During commissioning of the electric part turn actuator manually or electrically, the posion of an aached valve is
changed. This allows the flow of gases, vapours, liquids, etc. are enabled or interrupted.
- Check that the valve is actually closed 100 percent when the controller signals the corresponding posion!
- Avoid being trapped by suitable measures that by moving parts limbs.
- The actuator may be used only for the purpose it was designed.
- Open the electric rotary actuator only so far as it is described in this documentaon.
- Before mounng the actuator is the ease of movement of the actuator to consider.
- All cables that are to be connected to the supply, before the electrical installaon.
- Upon compleon of maintenance or repair, check the correct funcon and possibly adhering to the target angular
posion of the actuator and the funcon of the adjusted to the angular posions switch.
- To clean the housing, do not use abrasive, corrosive or flammable cleaners or high-pressure cleaning equipment.
