Start-up
During the start-up of the actuator, proceed as follows:
1.
Check that the pressure and quality of the air supply (filtering degree, dehydration)
are as prescript. Check that the feed voltage values of the electric components
(solenoid valve coils, micro-switches, pressure switches, etc.) are as prescript.
2.
Check that the actuator controls work properly (remote control, local control,
emergency controls, etc.).
3.
Check that the required remote signals (valve position, air pressure, etc.) are correct.
4.
Check that the setting of the components of the actuator control unit (pressure
regulator, pressure switches, flow control valves, etc.) meet the plant requirements.
5.
Check that there are not leaks in the pneumatic connections. If necessary tighten
the nuts of the pipe fittings.
6.
Remove all rust and, in accordance with the applicable painting specifications,
repair paint-coat that has been damaged during transport, storage or assembly.
