Schindler 5500 Error Codes Best Free

: The motor control has detected an encoder failure.

Standard reset procedures can often clear non-fatal errors and reinitialize the system.

Switch off the main circuit breaker (JH), wait 3 seconds, and switch it back on.

: The drive system is blocked (BARMAG error); requires a drive reset .

The car is out of service but available for inspection. Check the error log for the root cause. schindler 5500 error codes free

However, when the 5500 throws a fault, the proprietary nature of Schindler tools (like the Service Tool or LOP interface) often leaves building owners and independent mechanics in the dark. Official service contracts are expensive, and paying for a technician to simply read a code can be frustrating.

| Code | Description | Likely Cause | Action | |------|-------------|--------------|--------| | | Overvoltage on DC link | Regenerative braking issue, mains voltage spike | Check braking resistor, measure incoming voltage | | 1102 | Undervoltage on DC link | Mains dip, blown fuse, weak rectifier | Inspect mains supply, replace fuses, test drive input | | 1120 | Drive overcurrent (instantaneous) | Short circuit in motor windings or cable | Megger test motor and cables | | 1135 | Overspeed detection | Brake not holding, encoder failure | Check brake linings, verify encoder coupling | | 1201 | Inverter overtemperature | Cooling fan failed, high ambient temperature | Clean heat sink, replace fan, check ventilation |

: The Suspension Traction Media (STM) has reached its end of life.

: Redo the CLC calibration and check for loose load cell wiring. : The motor control has detected an encoder failure

Calibration issues or signal out of range for the LMS (Load Measuring System). Recalibration using a known load is often necessary.

Loss of communication between the main controller and the car operating panel (COP) or hall nodes.

: The brake contactor (SB) engages prematurely during the stop state. Check for auxiliary micro-switch failures or manual intervention on the contactor body.

The Schindler 5500 Control System processes data via the CO MX main control board. If the elevator stops or enters a degraded mode, the fault logic cycles between status information and numeric codes on the built-in SMLCD screen. Understanding Fault Classes : The drive system is blocked (BARMAG error);

The elevator car failed to reach its target floor within the preset runtime window.

Note: Critical safety faults (like governor trips or overspeed errors) cannot be cleared by a simple reset and require mechanical inspection. Pro-Tips for Long-Term Maintenance

Check for hoistway mechanical blockages or severe guide-rail friction. Drive Trip Start Failure
