LIMP HOME MODE
On 40 amp or larger chargers, the IMC will continue to operate, but at a lesser output, if a power module fails.
This allows for the charger to continue to provide power, but at a reduced output amperage.
When the charger detects a failed module, the battery temperature portion of the display is replaced with an infor-
mation scroll and the charger enters alarm mode. Limp Home mode can be reset by cycling the AC power or en-
tering and then exiting SETUP mode. If the defective power module is still present, the IMC will re−enter reduced
output mode and an alarm will be displayed.
Chargers that Limp Home mode has activated should be returned to Charles Industries, Ltd. for repair.

IMC Series FAILURE AND REPLACEMENT
At Charles, we take pride in designing and building high quality, tough products. As such, it is rare that a charger
will fail.
However, sometimes a charger does fail. In this case, you can quickly restore the same configuration to the re-
placement charger as follows:
1.
Transfer the current settings by removing the Smart Memory Button from the failed charger and
installing it into the new charger. The Smart Memory Button is located under the protective cap in the
Main Wiring Compartment. Once transferred, the new charger will assume the same configuration as
was on the failed charger prior to the failure.
2.
Power down both systems. Remove the protective cap on both systems and transfer the Smart
Memory Button from the failed charger to the new charger. Replace the protective cap.
