Applicable Systems
IRC5
Symptoms
CMOS battery low. The controller CMOS battery voltage is low. Controller configuration data may be at risk.
Possible Causes
- CMOS battery near end of life
- Battery connector loose or corroded
- Battery charging circuit fault
- Extended power-off period depleting battery
Troubleshooting Steps
- Step 1: Check the equipment status and fault indicators to confirm the active fault code
Fault indicator or HMI displays code 37053 as active - Step 2: Verify all electrical connections, wiring harnesses, and connector seating
All connections secure, no corrosion, loose pins, or damaged wires - Step 3: Check the battery voltage with a multimeter at the battery holder or terminal
Battery voltage above the minimum threshold (typically 2.7V for 3V lithium) - Step 4: If battery is depleted, replace it with the manufacturer-specified battery type
New battery installed, voltage measures nominal value - Step 5: Reload the configuration or program from a known-good backup
Configuration loads successfully and equipment enters normal state - Step 6: Verify all parameters and settings are correct after reload
All parameters match the backup or factory defaults
How to Reset
To reset: 1) Identify and fix the root cause described in the fault symptoms. 2) Press RESET on the HMI or controller, or power-cycle the equipment. 3) If the fault recurs, contact manufacturer service. Caution: Document the fault code and context before resetting.
Frequently Asked Questions
- Q: What does fault code 37053 mean on the ABB IRC5?
Fault 37053 on the ABB IRC5 indicates: CMOS battery low. The controller CMOS battery voltage is low. Controller configuration data may be at risk. Refer to the equipment manual and manufacturer support for specific troubleshooting steps.
- Q: Can I continue operating the equipment with fault 37053 active?
No. The equipment has detected a fault condition and has taken protective action (typically stopping or derating). Continuing to operate without fixing the root cause may cause further damage. Always investigate and fix the fault before resuming operation.
