Pneumatic Piping Conditions-
- Fully purge the piping from debris.
- Use clean air, fully removed of
humidity and dust.
- Use a CVS filter regulator to
maintain constant supply pressure.
- When using a double action
positioner as a single acting type,
close off either OUT1 or OUT2 and
remove pressure gauge to close its
connection.
Pilot Valve-
When the positioner is attached to a
small capacity actuator, hunting may
occur. In this situation a pilot valve
with a smaller output orifice may be
used for OUT1 and OUT 2. The output
orifice is interchangeable.
Using a Phillips screwdriver remove 4
screws and relay. Turn relay upside
down.
Upon removing the O-ring from
OUT1 and OUT2, place the
appropriate orifice in and re install
the O-Ring to OUT1 and OUT2. Re
install relay.
Ensure that dust and debris does not
enter the port hole when installing
the output orifice.
Should hunting not be resolved by
installing output orifice, contact a
CVS Controls Representative.
