Safety advice
3.1.2 Safety advice for adjustment and starting
As a result of the starting (electrically or by hand) of the actuator, the position of a slide / valve /
flap or the like on which it is flange-mounted - referred to below as the actuating element - will be
changed!
As a result, the flow of gases, steam, liquid, etc. may be enabled or interrupted.
Satisfy yourself that, as a result of the starting or the test adjustments on the actuator, no potential
hazards will be produced for personnel or the environment!
If necessary set up warning signs in order to prevent the inadvertent starting up or shutting down
of the devices / machines / plant!
After completing the adjustment, check the correct function and, if appropriate, compliance with
the intended angular position of the actuator and the function of the switches of the adjusted to
the angular positions!
Check the function of the end position switches.
Check whether the actuating element is actually 100 per cent closed when the controller signals
the corresponding end stop.
Through suitable measures, prevent that limbs being trapped by moving actuating elements!
Check the correct function of the safety devices (for example emergency push off buttons / safety
valves, etc.
Carry out the starting or the adjustment only in accordance with the instructions described in this
documentation!
In case of adjustments on an actuator which is open and switched on (ready to use), there is a
risk that live parts can be touched.
The adjustments must therefore be carried out only by an electrician or a person having adequate
training, who is aware of the potential hazard.
