•
intended utilization of the actuator (Chapter 3.1);
•
unusual sounds, severe vibrations or increased temperatures;
•
examine the correct tightening torque and impermeability of fixing screws, cable entries, cable glands and sealing plugs;
•
the condition of the electrical lines.
In case of malfunctions, you have to stop the actuator and remedy the malfunction.
All persons who work on installation, commissioning and setting must
•
be specially trained and qualified;
•
be mentally and physically capable;
•
observe the operating instructions.
•
Valves, levers and connecting rods are moving during actuator operation.
