Installation
Should other valve accessories be used
which vent the actuator (e.g. solenoid valve,
volume booster, quick exhaust valve), this ex-
haust air must also be included in the purg-
ing function. The connection over the adapt-
er at the positioner must be protected with a
check valve (e.g. screw fitting with restriction
G ¼, order no. 1991-5777) or ¼ NPT (or
-
der no. 1992-3178) mounted in the piping.
Otherwise the pressure in the positioner
housing would rise above the ambient pres-
sure and damage the positioner when the
exhausting components respond suddenly.
5.7 Pneumatic connections
Risk of injury by possible movement of ex-
posed parts (positioner, actuator or valve)
after connecting the signal pressure.
Î
Do not touch or block exposed moving
parts.
Incorrect connection of the supply air will
damage the positioner and will lead to
malfunction.
Î
Screw the screw fittings into the connect -
ing plate, pressure gauge mounting
block or connection block from the ac
-
cessories.
The pneumatic ports are located on the back
of the positioner.
Risk of malfunction due to failure to comply
with air quality requirements.
Î
Only use supply air that is dry and free
of oil and dust.
Î
Read the maintenance instructions for
upstream pressure reducing stations.
Î
Blow through all air pipes and hoses
thoroughly before connecting them.
