Commissioning
!
WARNING
Installation, commissioning and maintenance and repair works should be made by
qualified staff. Any calibration relative to functional aspects of the actuator are preset
at the factory, except the angular stroke setting because for this setting operation,
the actuator must be placed on to the valve (see Section 3.4) Before any modifications
please read Biffi Italia s.r.l.
Upon actuator commissioning please carry out the following checks:
•
Check that the pressure and quality of the air supply (filtering degree, dehydration)
are as prescribed. Check that the feed voltage values of the electrical components
(solenoid valve coils, micro-switches, pressure switches, etc.) are as prescribed.
•
Check that the actuator controls work properly (remote control, local control,
emergency controls, etc.).
•
Check that the required remote signals (valve position, air pressure, etc.) are correct.
•
Check that the setting of the components of the actuator control unit
(pressure regulator, pressure switches, flow control valves, etc.) meet the
plant requirements.
•
Check there are no leakages in the pneumatic connections. If necessary, tighten
the nuts of the pipe fittings.
•
Remove all rust and, in accordance with the applicable painting specifications,
repair paint-coat that has been damaged during transport, storage or assembly.
