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 re-install 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.
