Loss of communication with a board on the LON network, often a hall button (HPB). STM (Belt) Fault Slack belt detected or belt life limit has been reached. Subsystem Fault Categories

: Some minor faults can be cleared by switching off the main power and battery supply for roughly 5 seconds before restarting. Resetting SALSIS

| Error Code | Short Description | Detailed Explanation | Common Causes & Actions | | :--- | :--- | :--- | :--- | | | General Configuration Error | A non-specific system configuration error. Often appears after hardware replacement or software updates. | Power cycle the controller after a single reset (avoid double resets). Check all safety switch loops. Perform a new system "learn trip" if hardware was changed. | | 703 | Overcurrent – Drive | Motor current exceeds the maximum allowable value at constant speed. Limits depend on motor type (e.g., factor 1.15 for direct drive, 1.25 for worm gear). | Inspect for mechanical blockages (stuck brakes, seized rollers). Check for short circuits in motor wiring. Verify correct parameter settings for motor nominal current. | | 704 | Encoder Fail | The motor position encoder feedback signal is missing or corrupted. The PIOVECxx controller board detects the fault. | Inspect encoder cable connections for damage or loose wiring. Clean encoder disc or replace faulty encoder. Ensure proper shield grounding. | | 705 | Speed Diff | Speed difference between the reference value and actual tachometer feedback exceeds the permitted tolerance (OVER_SPEED_FACT). | Check for motor brake dragging. Verify encoder alignment. Perform a complete "learn trip" to re-calibrate speed profiles. | | 1501 | Invalid Car Position | The car position encoder reading is outside the learnt floor range (outside 1m above top or below bottom floor). Not reported when learn trip is active or during montage (JMOF on). | Perform a learn trip. Inspect encoder for physical movement when car is stationary. Replace faulty encoder. | | 1502 | Position Jump | Calculated car position difference between consecutive 10 ms readings exceeds 240 mm. After 5 cycles, an emergency stop occurs. | Check encoder wiring for EMC interference. Replace car position encoder. Check all encoder connectors for secure fit. | | 1505 | Invalid Floor Position | Inconsistent floor position data detected during a trip, causing a safety block. | Same as 1501/1502. Perform a learn trip. Inspect floor magnets or vanes if used. Verify correct input signals on interface board. | | 4305 | Overshoot/Position Error | The elevator overshot a floor target. Often occurs after a Category 1 (CAT 1) inspection run or when final limit switches are triggered. | Check final limit switch wiring. Perform a learn trip to redefine extreme floor positions. Investigate encoder performance. | | Door Mass Error | Door Mechanism Fault | Indicates the mobile door mass is too low (< 10 kg) or door closing force is out of range. | Measure and adjust door mass (add weight if too low). Check door closing spring (ensure -30 to 200 N/m). Perform automatic door configuration. |

Indicated by "E_DOOR" codes. These involve landing lock issues, door zone sensor failures, or motor obstruction.

Codes are typically displayed as a combination of a (e.g., DQ, TE, GC) and a Number (e.g., 2109).

Inspect inverter IGBT modules and output wiring terminals for open circuits. Shaft Positioning & SALSIS Errors
