3.4.11 Serial Driver

The Serial Driver module performs serial-to-parallel conversion on the stepper motor drive signals
from the BMCC. The module also contains four normally open relays under BMCC control. Two of the
relays drive the motor-cooling solenoids, and the other two are used to indicate compressor fault
status and running status. The status relays can be wired to external control circuits.

3.4.12 Backplane

The Backplane physically interconnects the onboard plug-in modules with the power electronics, IGV
stepper motor, motor-cooling solenoids, rotor position sensors, and pressure/temperature sensors.
The Backplane also features onboard, low-voltage DC-DC converters for gene15V, -15V, +5V,
and +17V from an input of +24VDC. The Backplane receives its +24VDC power input from the High-
Voltage (HV) DC-DC Converter mounted on the topside of the compressor.

The Backplane is also equipped with status-indicating Light-Emitting Diodes (LEDs). All LEDs are yellow
except for the alarm LED, which is green/red. Table 3-1 Backplane LEDs describe the LEDs functions.

Table 3-1 Backplane LEDs

3.4.13 High-Voltage DC-DC Converter

DC-DC converters supply and electrically isolate the high and low DC voltages that are required by the
control circuits. The HV DC-DC Converter delivers 24VDC and 250VDC from an input of 460-900VDC. The
24VDC and 250VDC are used to power the Backplane and magnetic bearing PWM Amplifier, respectively.

3.5 Magnetic Bearing System

3.5.1 Overview

A rotating shaft, under changing load conditions, will experience forces in both radial and axial
directions. In order to compensate for these forces, a five-axis bearing system is used, incorporating
two radial bearings of two axes each, and one thrust (axial) bearing (refer to "Figure 3-7 Magnetic
Bearing Configuration").

Figure 3-7 Magnetic Bearing Configuration

LED

Function

+5V, +15V, +17HV, +24V

LEDs are lighted when DC power is available.

Cool -H, Cool -L

LEDs are lighted when their respective coil is energized.

Run

LED is lighted when the shaft is spinning.

Alarm

LED is green when in normal status, red when in alarm status.

D13, D14, D15, D16

LEDs indicate IGV status and flash when IGV is moving.
