Set inlet pressure
The inlet pressure (i.e. the plant air kit outlet pressure) is the pressure that the printer
needs to operate. It must be 0.7 bar (+0.3/ -0.1) above the printer operating pressure at
all times.
1. Select Production/Maintenance/ELV status modification to display the operating
pressure:
The operating pressure is displayed on the screen by default. This is the value required
to maintain the jet speed, and it varies according to the type of ink and the viscosity. It
should therefore be checked at the correct viscosity.
2. Go to the Phase line then press the
key to display TEST.
3. Go to the Operating pressure line, then press the
key to open the
COMPRESSOR / DIVIDER BRIDGE selection box.
4. Select COMPRESSOR and confirm. Wait for a few seconds. The pressure value is
displayed.
5. Adjust the pressure if required by turning the adjustment screw (3).
Set the vacuum pressure
The vacuum pressure value depends on the type of ink and the type of printer concerned.
Refer to the Ink Running Specification Sheet or the technical data sheet for the ink used to
obtain this value and adjust the plant air kit, if required.
Adjust the vacuum pressure if required by turning the adjustment screw (7).
