20. Differential pressure on controller display should rise above P3 pressure and
purge timer will start counting.
21. After purging, the GasEye will be powered up and differential pressure will be
kept between P2 and P4 pressure. Slow oscillations of manifold may be
noticed.
22. Power for GasEye system will be interrupted if differential pressure in
enclosure drops below P1 pressure.
Zone 2 and 22 purging system installation with GasEye
Cross-Duct Multi Gas
1. Connect 6 mm gas pipe (13) into manifold (7) input. Make sure that there will
be no purging gas flow into system, until installation is complete and purging
controller is energized.
2. Connect 6mm gas pipe (14) into manifold (7) output and GasEye receiver
enclosure (2) gas input with ATEX certified manometer (20) in between (using
6mm tee connector). Make sure that GasEye receiver gas inlets are not sealed
with plugs.
3. Install manifold control signal cable (10) into 5500 controller internal terminals
through one of the M20 glands.
Manifold (7) should be placed on the GasEye receiver side and connected
through 3x1mm2 control signal cable (10) with purging controller (6) placed on
the GasEye central unit side.

4. Connect 1/4" pressure signal pipe (11) into “enclosure pressure control” input
in purging controller (6). Other end of the pipe connects into threaded output
on vent enclosure (8).
5. Connect 6mm gas pipe (19) into vent enclosure (8) input and GasEye central
unit enclosure (3) gas output. Make sure that GasEye central unit gas inlets
are not sealed with plugs.
6. Connect 3x1.5mm2 cable (12) between 5500-type purging controller (6)
(through M20 gland) and GasEye central unit (3). Length of the cable should
be <30m.
