AC Transformer Box + (ATB+) | |
The ATB+ is located on the subpanel within the control panel.
Replacement Procedure
- Shut down the engine. Remove the positive lead wire from the battery.
- Make sure that all wires at the terminal strip of the ATB+ are marked with the respective termination point. During reassembly, these wires must be reattached to the correct terminal. Remove all external wires from the terminal strip.
- Disconnect the ATB+ connector from the harness connector.
- Remove all mounting nuts and mounting screws that fasten the ATB+ to the subpanel. Remove the ATB+.
- Place the new ATB+ in the subpanel. Install the mounting nuts and mounting screws. Tighten the mounting nuts and mounting screws.
- Reconnect the harness connector to the ATB+. Reconnect all the wires to the terminal strip that were removed. Reconnect the positive lead wire to the battery. If necessary, see the Generator Set Wiring Diagram in Testing And Adjusting, "Schematics and Wiring Diagrams".
- Program the bar code (calibration value) for the voltmeter/ammeter into the GSC+. See System Operation, "Voltmeter/Ammeter Programming OP8".
- If the generator set is operating in parallel with another generator set and the voltmeter values must match, then reprogram the AC offset. See System Operation, "AC Offset Adjustment OP10".
