HEX ↔ Decimal Conversion:
-
For SET0=2/3/4/8, press SW1△ to toggle between HEX and decimal formats.
-
-
Position Diagnostics:
-
SET0=9:
Eindicates *out-of-leveling-zone* status. -
SET0=D:
-99= 25.3m below mid-shaft;+99= 25.3m above.
-
-
Load Monitoring:
-
SET0=F: Displays live load percentage (e.g.,
75= 75% capacity).
-
3.3 Example Use Cases
-
Leveling Calibration Check:
-
Set SET0=9 → Verify car is fully leveled (e.g.,
4= floor 4 aligned).
-
-
Overload Verification:
-
Set SET0=F → Confirm load ≤110% during test runs.
-
-
Speed Discrepancy Analysis:
-
Compare SET0=6 (Real-Time) vs. SET0=7 (Model) to identify drive issues.

4. Fault Code Diagnostics
4.1 Fault Code Interpretation
Set rotary switches to MON1=0, MON0=0 to display active faults on 7SEG1/2. Blinking indicates unresolved issues.

| 5 | — | Safety Circuit Relays | 29/60 relays, door lock circuits |
| 6 | — | Safety Loop Fault | GOV, BTP, UL/DL switches |
| 7 | — | Door System Error | Door operator, CSC/DSR signals |

| F | — | Reserved | ―― |
4.2 Operational Notes
-
Blinking Display:
-
Active faults cause 7SEG1/2 to blink until resolved.
-
-
Multi-Code Prioritization:
-
Simultaneous faults display highest-priority code (priority: 0 > 1 > ... > E).
-
-
Post-Repair Reset:
-
Clear codes by cycling power after fault resolution.
