SECTION 2
INSTALLATION
INSPECTION
– Inspect all parts are present and undamaged in the sequencing kit before removing the
compressor from operation.
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout power
supply to the starter before removing valves, caps, plugs, fittings, bolts and
filters.
Install Sequencing Pressure Connections
Note: One kit is required per machine being sequenced
When using kit 313ETK6028 for a package with 2 pressure transducers:
1. Remove knockout on control cabinet and install the bulkhead fitting (GDI Part No. 64EB368)
included in the sequencing kit. Refer to the Operators Manual of the machine being sequenced
for the proper location. If no knockout exists, a new hole will need to be made.
2.
Connect bulkhead fitting to the ¼” system pressure feedback tube from the plant receiver tank,
as shown in
Figure 1-1
- Sequencing Pressure Connections
.
3. Install system pressure transducer (GDI Part No. 88H369) in the bulkhead fitting inside the
control cabinet.
4. Using the pressure transducer harness (GDI Part No. VP1033693), connect pressure transducer
to AirSmart G2 controller. Connect the red wire to pin 5 on connector P2, and the white wire to
pin 6 on connector P2, as shown in
Figure 2-1
– Sequencing Electrical Connections
. Do
nothing with the black wire.
When using kit 314ETK6028 for a package with 3 pressure transducers:
1. The above steps should already be finished and no new knockouts need to be made in the
electrical panel, and no new wiring needs to be added in the panel other than the sequencing
communication cables. A small tubing modification will need to be made to connect the system
pressure to the package.
2. Locate the connection for the plant pressure sensor. This is right next to the moisture trap.
3. Remove the tubing from the 90
°
fitting. Then remove the 90
°
fitting.
4. Install a
¼” pipe plug (GDI Part No. 64AC2) into the port where the 90
°
fitting was removed.
5. Install a ¼ x ¼ tubing fitting (GDI Part No. 86E244) on the tubing that was just removed.
6. Install the tubing that is coming from the location sensing the system pressure to the ¼ x ¼ tubing
union.
Sequencing Network Connections
1.
If there is not enough existing empty DIN rail available in the control cabinet cut the supplied
DIN rail (GDI Part No. 24CA5991) to a reasonable length and attach to back panel using the
supplied self tapping screws (GDI Part No. 75LM302) or a suitable replacement.
The RJ-45 Splitter must be installed in the low voltage section of the control panel to avoid
