Replace The Electronic Board - ABB RMC-100 User Manual

1. Verify that the LL battery alarm does not display on the LCD. Or measure the lithium battery to
verify that it registers more than 3.6 V. If the lithium battery is low, replace the lithium battery
first according to section 8.8.5.
2. Remove charger and battery cables from the RMC for the battery mode according to section
8.7.1.
3. Remove the battery and battery cable from the existing battery.
4. Put a new battery in place.
5. Connect the battery cable to the new battery terminals (observing polarity).
6. Reconnect battery and charger cables to the RMC, as described for the battery mode in section
8.7.2.
7. Verify on the LCD that the controller's power-on sequence completes.

Replace the electronic board

NOTICE – Equipment damage. The electronic board inside the RMC housing is susceptible
to damage by static electricity or improper handling. Wear a grounding strap when handling
the board to prevent this.
A grounding strap is a conductive device that makes a connection between the person
handling the board and a high-quality ground point. Wear a ground strap on your body
before handling the board, then connect it to a grounded point. This discharges electrical
static buildup from the body to the ground and prevents static from discharging to the
board.
NOTICE – Loss of data. Perform the procedures in section 8.1,
configuration
save the device configuration to avoid data loss.
Restore the saved configuration to the RMC and avoid time-consuming manual
reconfiguration of the controller. If it requires a full software restoration, the operating
system and firmware must be the same as in the replaced board. Verify that all software is
included in the backup package (all software is saved, not only the configuration).
To remove and replace the board:
1. Perform the procedures in section 8.1,
software is saved to the backup package.
2. Remove power from the RMC according to section 8.7.1.
3. Remove terminal connectors from I/O and COMM ports.
4. Remove serial communication modules.
5. Remove cables from communication ports (USB, Ethernet, or MMI).
6. Remove TFIO modules from the TFIO A and B interfaces (if used).
7. Remove the RMC from the DIN rail according to section 8.8.3.
8. Remove the housing cover according to section 8.8.4.
9. Remove the screws holding the electronic board to the housing base.
10. Remove the existing board.
11. Position the new electronic board and replace the screws to hold the board to the housing base.
Verify that the board has a lithium battery installed. If you use the lithium battery from the
board being replaced, test to verify that the voltage is not less than 3.6 Vdc.
12. Reinsert the housing cover.
13. Remount the RMC on the DIN rail.
14. Reconnect terminal connectors to I/O and COMM ports.
15. Reinsert serial communication modules.
16. Reconnect cables to communication ports (USB, Ethernet, or MMI).
17. Reconnect TFIO modules to the TFIO A and B interfaces (if used).
18. Reconnect power to the controller according to section 8.7.2.
19. Verify on the LCD that the controller's power-on sequence completes.
20. Set the lithium battery backup switch to Enable. See section 3.8.
