Pre-Removal Steps

Bearing service is always performed on both the upper and lower bearings.

Note: Always change the lower bearing first, then change the upper bearing.

Note: These steps are defined for electrical high risk maintenance of the cabinet components located behind the locked doors. Follow these steps before performing maintenance on internal components. It is necessary to shut down all input to the Flywheel Cabinet for this operation both AC and DC. The customer load will be unprotected.

Note: This cabinet has two sources of voltage. Control AC voltage and the DC Bus.

------ WARNING! ------

When servicing or repairing electric power generation equipment:

  • Make sure the unit is either locked out or tagged DO NOT OPERATE.

  • Remove all fuses.

  • Make sure the generator engine is stopped.

  • Make sure all batteries are disconnected.

  • Make sure all capacitors are discharged.

  • Make sure residual voltage in the rotor, stator and the generator is discharged.

Failure to do so could result in personal injury or death.

----------------------

------ WARNING! ------

When servicing or repairing electric power generation equipment:

Make sure the unit is off-line (disconnected from utility and/or other generators power service), and either locked out or tagged DO NOT OPERATE. Remove all fuses.

----------------------

------ WARNING! ------

Personal injury or death can result from high voltage.

When power generation equipment must be in operation to make tests and/or adjustments, high voltage and current are present.

Improper test equipment can fail and present a high voltage shock hazard to its user.

Use electrical safety gloves when you are working in the cabinets.

Make sure the testing equipment is designed for and correctly operated for high voltage and current tests being made.

----------------------

  1. Brake the flywheel. Execution of this command can be performed using the Ctrl-X keystrokes in UPSView.

  1. Turn the keyswitch to the "Spindown/Offline" position.

  1. Transfer the UPS/SMS or MMU to bypass mode.

    The UPS/SMS or MMU needs to be put into the bypass mode before any work is done to the cabinet. Refer to Testing and Adjusting, "Transfer to Bypass Mode".

  1. Discharge the DC Bus. Let the DC Bus bleed down to below 24VDC.

  1. Open the doors of the cabinet by using a 5/16-inch hex key on the upper and lower latches.

  1. Disconnect the DC bus by using the DC Disconnect Handle on the middle metal safety shield.

    Note: Verify the green light is on before operating the DC Disconnect Switch Handle.

  1. Open the circuit breaker (CB1) that is located on the lower left panel on the Flywheel Cabinet.

  1. Discharge the capacitors by allowing the capacitor banks in the UPS/SMS or MMU to bleed down for ten minutes.

  1. Remove the following components: the lower shield, the middle shield, the fan shield and the bottom cabinet frame rail.

  1. Remove the middle fan to gain access to the metal cover over the top flywheel upper bearing.

  1. Remove the metal shield between the 2 flywheels to gain access to the upper bearing on the lower flywheel and the lower bearing on the upper flywheel.

Lower Bearing Cartridge Remove and Install

Note: Before you begin, the flywheel cabinet must be offline, de-energized, and the flywheel at zero RPM. Have the appropriate replacement parts and tools at hand to perform the bearing change.

Continuity Check

After the charge drain and the load cell is installed, check for continuity using the following procedure:

  1. The commutation sensor should still be disassembled from the flywheel. If the commutation sensor is not removed, remove the commutation sensor.

  1. With a standard ohmmeter, check continuity between the retaining bolt of the upper rotor and any unpainted, bare metal surface on the flywheel housing.

    If there is no continuity, the charge drain has not been installed and adjusted properly.

  1. If continuity does not exist:

    • Remove the load cell from the lower bearing cartridge.

    • Check the installation of the charge drain and the height adjustment.

    • Verify that the contact surfaces are clean.

    • Check continuity between the upper retaining bolts for the rotor and the lower retaining bolts for the rotor.

    • Reinstall the load cell.

    • Repeat the check for continuity.

  1. Once continuity is verified, reinstall the commutation sensor onto the upper bearing cartridge.

  1. Apply a light coat of vacuum grease to the commutation sensor O-ring. Reinstall the commutation sensor onto the assembly in the O-ring groove.

  1. Reinstall the commutation sensor with the three mounting screws.

  1. Remove the support shims for the rotor.

    If the support shims for the rotor are still bound between the rotor and pole ring surface, remove the "load cell" and add a "2 mil" shim to the shim package for the load cell. Reinstall the "load cell".

    Note: If the shim package for the bearing cartridge is measured correctly, then no more than one shim should be required in this adjustment. If the gap between the retainer and bearing is less than "6 mils", the cartridge must be removed and an additional "2 mil" shim must be added to the brass shim package:

    • If the gap is "7 mils", one "2 mil" shim may be added to the shim package for the load cell.

    • If the gap is "9 mils", two "2 mil" shims may be added to the "Load Cell" shim package.

    If the load plate is stuck, try to wiggle the load plate by hand. Do not use a screwdriver or any other tool because of the risk of damaging the charge drain.

  1. Apply Dow-Corning high vacuum grease to the O-rings that are located on four plugs.

  1. Install the three plugs.

  1. Connect the lower harness from the Flywheel Interface Board to the load cell connector.
