How to Replace a CE-R1
STEP 1: Use the side handle to remove CE R1 from the shelf. RA 3048 rectifier modules are operating normally even without CE R1.
STEP 2: Insert the replacement control unit fully into the shelf until it fits the slot tightly. Wait for a few seconds until the LED on replacement CE R1 shows solid GREEN.
STEP 3: Please set desired parameters on replacement CE R1, or the settings will follow factory default value when inserting new control unit.
In case of any error message or warning LED indicators are on (ex. Flashing organe), please refer to user manual for troubleshooting or contact COTE K local distributor for assistance.
