: Motor or drive temperature has normalized after an overtemperature event.
: Auxiliary contactors (RH/RH1) fail to pick up when a trip sequence is initiated. The controller detects an open connection or an improperly scaled MAX_DOOR_ZONE configuration parameter.
A general break in the safety loop has been detected.
Comprehensive troubleshooting documentation can often be found on public document sharing sites, such as Scribd or StuDocu by searching for "Schindler 5500 commissioning manual" or "SMART error codes". Note: Always ensure the manual matches your specific project (rel. 02, etc.). Conclusion schindler 5500 error codes free
A technician on the Vatortrader forum reported a situation where the car overshot the top floor and entered the overhead during an inspection run.
Actuated pit stop switches, blown safety circuit fuses, or tripped car top stop buttons. Troubleshooting Steps:
The Schindler 5500 utilizes high-efficiency regenerative drives (such as the VF33BR or VF44BR). Faults in this category indicate electrical anomalies in power delivery. Error 0302: Inverter Overcurrent : Motor or drive temperature has normalized after
Ensure the main controller stop switch is in the "Run" position.
From documents like the Schindler Elevator Error Codes Guide and drive manuals:
While specific, detailed documentation might be proprietary and restricted to authorized personnel or customers, there are a few strategies you can use to find information on Schindler 5500 error codes: A general break in the safety loop has been detected
Check the incoming voltage, check the rectifier on the drive, and check for a faulty encoder. Encoder Fault:
For motor control (ACVF) errors, switch off the main circuit breaker (JH), wait 3 seconds, and switch it back on. Accessing the Fault Log
Maintenance and troubleshooting should only be performed by qualified elevator technicians to ensure safety and compliance with local regulations. Section 7 - Troubleshooting
The internal heat-sink thermistor has exceeded maximum safety limits.
| 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 |
