Instructions for the operator
During the start-up of the BV, proceed as follows:
-
check that the pressure and quality of the air supply (filtering degree, dehydration) are as prescribed;
-
check that there are not leak 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;
-
prior to operation, turn the bypass adjusting screw counter clockwise to the fully opened position. With
the actuator in operation, slowly turn the bypass screw until the booster operates in response to large
changes in the input signal yet allows small changes to move the actuator without booster firing.
Warning
The BV has parts under pressure. Use the due caution. Use individual protections
provided for by the laws and provisions in force.
