COMMISSIONING
Installation, commissioning and maintenance and repair
works should be made by qualified staff.
Upon actuator commissioning please carry out the following checks:
❑
Check that paint is not be damaged during transport, if necessary
repair the damages to paint coat.
❑
Check that the values of hydraulic supply available in the system are
compatible with those reported on the identification plate of the
actuator (Figure 2) and on the documentation supplied.
❑
Check that the feed voltage values of the electric components
(solenoid valve coils, micro-switches, pressure switches, etc.) are
compatible with those reported on the identification plate of the
actuator (Figure 1).
❑
Check that the setting of the components of the actuator control unit
(pressure regulator, pressure switches, flow control valves, etc.)
meet the plant requirements.
❑
Carry out all kinds of operations and check their proper execution
(Sect. 3.3).
❑
Check the absence of leakages in the hydraulic connections.
If necessary tighten the nuts of the pipe-fittings
❑
Check proper operation of all the due signalling ( valve position,
hydraulic supply pressure etc. )
❑
Make a complete functional test in order to verify all the operations
are executed according to operating schematic diagram supplied.
