Figure 69 - Disconnecting
Power to the IGV Motor
3.13.4.1 IGV Removal
3.13.4.2 IGV Installation
1. Isolate compressor power.
2. To disconnect power to the IGV Motor, remove
the clamp securing the connector. See Figure 68
(IGV Motor Feed Through).
3. Detach the connector on the IGV Housing. See
Figure 69 (Disconnecting the Power to the IGV
Motor).
1. Install the O-ring into the groove of the main
compressor housing.
2. Position the IGV Housing in place.
3. Install the bolts and washers, tighten in a
diagonal pattern to 25Nm (18.4 ft./lb).
4. Leak test compressor to appropriate pressure
and industry accepted standards.
5. Evacuate compressor to appropriate level and
industry accepted standards.
6. Reconnect the cable at the feed through
connector on the IGV Housing.
7. Secure the connector clamp.
8. Reconnect the suction sensor connector.
4. Recover the refrigerant from the compressor.
5. Disconnect the cable at the suction sensor. See
Figure 67 (IGV Connections).
6. Remove the bolts that secure the IGV assembly
to the compressor housing. See Figure 67 (IGV
Connections).
7. Pull the IGV assembly away from the
compressor housing.
3.14 BMCC
3.14.1 Function
3.14.2 Connections
The BMCC is the central processor board of the
compressor. Based on sensor inputs, it controls
the bearing and motor system and maintains
compressor control within the operating limits.
• The BMCC uses +5VDC, +15VDC, and -15VDC
power supplied from the Backplane.
• The BMCC relays compressor information over
RS-485/RS-232 via Modbus communication.
The BMCC is connected to J2 and J3 on the
Backplane. See Figure 60 (Backplane Connections
and Test Points).
