Severity: Critical | Likely Result: Emergency stop, trapped passengers.
What it means: A device in the safety chain (series of switches) opened. This is a catch-all code; the sub-code tells the real story.
Sub-codes to watch:
Troubleshooting: You must reset the safety circuit manually from the machine room. Use a voltmeter to find the exact break in the 110V AC safety loop.
Status: High Severity – Can Cause Free Falls to Safety Gear
Description: The elevator controller lost synchronization between the car’s calculated position (based on encoder pulses) and the position reference system (magnetic tape or selector vanes in the hoistway). schindler 5500 error codes top
Common Causes:
Troubleshooting Steps:
Severity: Low (Comfort) | Likely Result: Interior lights flicker or go dark.
What it means: The 24V or 110V lighting supply is drawing too much current (usually >2A).
Common Causes:
Troubleshooting: This won’t stop the car, but passengers will panic. Replace with Schindler-approved LED kits.
On the Schindler 5500, fault codes are typically accessed in one of two ways:
Severity: Critical | Likely Result: Safety gear activation, rescue required.
What it means: The car’s actual speed exceeded the commanded speed or the safety governor threshold by more than 15%. This is rare but terrifying.
Common Causes:
Troubleshooting: Immediately check the governor rope tension and sheave groove wear. Verify encoder wiring shielding (EMI interference is common).
Status: Traffic Management, Not a True Fault
Description: In a Schindler 5500 group of 2–8 cars, this code indicates that the group dispatcher has assigned all calls, and a specific car is waiting for a landing call that has been taken by another car. Often misinterpreted as a jam.
Common Causes:
Troubleshooting Steps:
Unlike older systems, the 5500 uses a combination of hexadecimal and decimal codes. You will typically see a "F" code (Fault) followed by a number. Always check the secondary log for the exact time stamp—intermittent issues are common.
You will see F0900 (No Fault Recorded) frequently. This usually means a power glitch so short that the system rebooted before logging the real cause. If you see this, check the building’s input voltage.
