Actuators NK and VK, Position Controller ESR-NK 25
5 Assembly
WARNING
Moving components on the actuator and the valves connected to it
pose a risk of injury!
When the actuator is operated, the valves connected to it will also move.
When couplings are used between the actuator (series NK) and the valve,
there is a risk of injury due to moving parts.
The dangers include crushing, shearing off or drawing in of the upper
limbs.
–
The assembly or operation of a damaged actuator is not permitted.
–
Attach covers over the exposed moving actuator parts and the valve
once the actuator is installed before putting the actuator into service.
Observe DIN EN ISO 13857 (“Safety of machinery – Safety distances to
prevent hazard zones being reached by upper and lower limbs”) when
designing the protective covers.
–
The heat dissipation of the actuator must be ensured when additional
protective covers are installed. Non-observance may cause damage to
the actuator (e.g. due to overheating of the motor windings).
–
Verify the proper function of all protective equipment on your ma-
chine/plant.
–
Verify the correct operation of the actuator and of the valves moved by
the actuator after the assembly and the actuator setup are completed.
–
Always operate the actuator with the hood in place.
–
In order to reliably prevent an unexpected start-up of the actuator, the
actuator's power supply may not be connected during the installation
process.
