Auxiliary +24V Power Supply
An Isolated 24V Power Supply is built into the DC/DC converter (Connector
P3). This supply may be used for any customer supplied equipment requiring up
to 24 watts at +24 volts. This supply may also be used to power any custom drive
options, such as isolation modules for additional Process Control Outputs. The
health of this power supply is monitored in the drive.
ACB Analog Control Board Replacement
To replace the ACB Analog Control Boards:
1. Ensure that all medium voltage and control voltage power to the drive is
isolated and locked out.
2. It is required to remove the transparent sheet on top of the Drive Processor
Module and the Drive Processor Module also before removing the ACB.
Remove the transparent sheet on top of the DPM by removing the 4
screws.
3. Use static strap before removing any connectors.
4. Remove the connectors J4, J11 and J12 on DPM after proper
identification and marking if necessary. Use the electrical drawing as the
reference. Remove the 4 screws holding it on the standoffs above the ACB.
5. Gently remove the DPM mounted on the four, 34-pin connectors.
6. Remove the screws holding encoder interface board and gently remove the
board mounted on the 8 pin connector.
7. Remove the connectors J1, J2, J3, J4, J5, J6, J7,J8, J9, J10, J12, J13, J14,
J16, J22, J24, J25, J26, J27 on ACB after proper identification and
marking if necessary. Use the electrical drawing as the reference.
8. Remove the ACB board by removing the 4 screws, and 6 standoffs screwed
to support the DPM & encoder interface board.
9. Follow Steps 8 – 2 in reverse to reinstall the boards back into the low
voltage control cabinet.
10. Apply Low Voltage power and complete a System Test and Medium
Voltage tests to ensure the new board functions properly.
