EPP4 Pressure Regulator
INSTALLATION AND ELECTRICAL CONNECTIONS
INSTALLATION
Before connecting the regulator EPP4, pay attention to the
following instructions:
Connect the regulator as close as possible to the apparatus
which will be regulated (resulting in higher precision and
shorter response times);
Piping section of pressure supply should be sufficiently large;
Connect the air filter (50µ, Dew point 2°C) upstream from the
regulator, and a lubrificator if necessary, downstream;
It is recommended to mount the regulator in a vertical position,
electronic on top.
Set up the inlet pressure (max.: see page 2).
Connect the regulator to the pneumatic network.
Connect the pressure supply on the inlet port P and the regulation
circuit with the outlet port A.
Fluid: lubricated (1 gr/m
maxi) or non lubricated air and neutral gas

It is recommended to use a silencer in the exhaust R.
