When replacing parts, should technical assistance be required, contact the nearest ABB Automation
field office.
NECESSARY ORDERING INFORMATION
When communicating with ABB Automation for replacement of the main PCB,
reference the unit’s serial number to ensure the correct replacement assembly
is supplied. The necessary ordering information is provided on the instrument
data tag and on the manufacturing specification sheet supplied with that
particular controller.
In the event of a hardware malfunction, a replacement PCB can be quickly substituted for the
defective assembly to minimize downtime. Contact ABB Automation for instructions before returning
equipment. The defective PCB should be carefully packaged and returned, shipping charges pre-
paid, to the Repair Dept. of ABB Automation.
Do not wrap PCBs in plastic, as it can cause static
damage. It is suggested that the defective PCB be returned in the special bag in which the
replacement module was supplied.
