(1) Hinged panel
(2) APC controller board | |
The APC board (2) is located on the front hinged panel of the cabinet for the flywheel. All of the control signals for the inverters, field coil drivers, and the static switch originate from the controller. The controller sends control signals for the following components: static switch, inverters and field coil drivers. All of the status signals and telemetry signals in the system are sent to the controller for monitoring.
The controller (2) has the following functions:
- Provision of resources to allow control of the system processor, FPGA, DSP, related memory devices, and configuration devices
- Receiving, scaling, and processing analog telemetry information from the system that is being controlled
- Provision of data channels to receive information from satellite boards in the system
- Provision of data channels to send information to satellite boards in the system
- Provision of communication to users or other systems via RS-232/422, Ethernet, modem, and CAN
- Storage of calibration data and configuration data
- Tracking of the date and time
Data locks are used for the following components:
- FAN
- UIF
- ACI
- SIO
- FWI
Replace the battery every 5 years. The B1 battery is a CR2032 lithium.

APS board connections | |
Refer to Systems Operation, Testing and Adjusting, UENR3954, "Internal Component Preremoval Steps (Flywheel Cabinet)" in order to shut down the system and gain access to internal components.

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. When not in use, keep the module in a static-shield bag. Follow these guidelines when you handle any module: Touch a grounded object to discharge static potential. Wear an approved wrist-strap grounding device. Do not touch the bus connector or connector pins. Do not touch circuit components inside the module. If available, use a static-safe work station. |
- Disconnect all connectors from the board (2). Verify each connector in order to make sure that the label is present and legible. Verify the labeling of each connector with the location of the connector. Refer to Illustration 2.
- Remove the nine white plastic nuts that connect the APS board to the standoffs.
- Remove the APS board from all standoffs at the same time. Pinch the head of each stand-off so that the board is not locked to the stand-off but still attached. Remove the board by gently and evenly pulling the board from all the standoffs at the same time.

- Position the APC board in the cabinet over the nine white standoffs that are connected to the swing out panel. Install the APC board.
- Verify that all the standoffs are locked into the correct position. Install the white plastic nuts to secure the APS board to the standoffs.
- Connect the wire connectors. Verify the labeling of each connector for proper placement. Refer to Illustration 2.
- Calibrate the APC board. Refer to Systems Operation, Testing and Adjusting, UENR3954, "AC Voltage - Calibrate", Systems Operation, Testing and Adjusting, UENR3954, "AC Output Current - Calibrate", Systems Operation, Testing and Adjusting, UENR3954, "Vibration Sensor - Calibrate", Systems Operation, Testing and Adjusting, UENR3954, "Flywheel Telemetry - Calibrate", and Systems Operation, Testing and Adjusting, UENR3954, "Rotor Position Sensor - Calibrate".
