E40 Fault Code Fault Description:
When the E40 fault code appears, the elevator undergoes a power reset, moves to the next floor, and opens the door. This issue prevents the elevator from normal operation until it is resolved.
Understanding the E40 Fault Code:
The E40 fault code is primarily a system restriction implemented by the elevator manufacturer or maintenance company. It is designed to lock the elevator when scheduled maintenance is due or overdue. This ensures that necessary inspections and servicing are carried out to maintain the safety and reliability of the elevator.
For some elevator brands, such as SJEC, the E40 code is specifically used to restrict third-party maintenance companies from modifying the maintenance schedule. This means that even if a maintenance team is on-site, they may not be able to reset or clear the fault without factory authorization.
Possible Causes of the E40 Fault Code:
- Scheduled Maintenance Lock – The elevator has reached its maintenance interval and is now locked until servicing is verified.
- Factory-Set Restrictions – The manufacturer has embedded security settings that prevent unauthorized changes to maintenance schedules.
- Power Reset Conditions – The elevator system may have detected an anomaly and triggered a reset to safeguard operations.
How to Resolve the E40 Fault Code:
Since this fault is directly tied to manufacturer restrictions, standard troubleshooting methods such as power cycling the system or clearing errors from the control panel will not resolve the issue. The only way to reset the E40 fault is to:
- Contact the Elevator Manufacturer (SJEC or relevant brand) – The manufacturer’s technical team must visit the site to reset or update the maintenance schedule in the system.
- Verify Maintenance Records – Ensure that all required inspections and servicing have been completed before requesting a reset.
- Coordinate with an Authorized Technician – If your elevator is under a maintenance contract, liaise with the service provider to initiate the proper procedure.
Preventing Future E40 Faults:
- Schedule timely maintenance to avoid unexpected shutdowns due to overdue service locks.
- Ensure proper documentation of servicing so that manufacturer resets can be processed smoothly when needed.
- Consult with the elevator supplier to understand whether maintenance schedule adjustments are possible under your service contract.
For immediate assistance, please contact SJEC’s official support team or your elevator service provider to arrange for a factory-authorized reset.
