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.12 bar).
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
3
maxi) or non lubricated air and neutral gas
It is recommended to use a silencer in the exhaust R.

connector:
The female connector to mount is the 5 pole M12 connector (IEC
61076-2-101 model LF).
Use only straight connectors to keep access free for
both connectors
LED
Green:
the EPP works properly
Red flashing:
supply voltage is low or high (
15 %)
Red continuous: supply voltage is too low or too high (out of
specification, high risk of malfunction)
