3. Auto-Learning Procedure
-
Preparation:
-
Ensure car-top inspection switch (JREC) is ON.
-
Power ON the door operator.
-
Position elevator at floor level (include landing doors if possible).
-
-
Enter Inspection Mode:
-
PressINSP key (LED 5 ON).
-
-
Start Auto-Learning:
-
HoldSETUP key (LED 6)for>5 seconds.
-
LED 6 slow blink: Learning in progress.
-
-
Learning Sequence:
-
Door opens slightly → Locks.
-
Cycle 1: Open/close at reference speed.
-
Cycle 2: Open/close at reduced speed.
-
Cycle 3: Open/close at normal speed.
-
LED 6 OFF: Auto-learning successful.
-
-
Troubleshooting Failures:
-
*LEDs 1-4 & 6 rapid blink*: Setup error.
-
PressSETUP keyto clear error.

Key Notes for Technicians
-
Always verify landing door engagement during auto-learning.
-
Spring constant errors (Code 13/14) require mechanical adjustment.
-
Use CAN analyzer for persistent communication faults (LED 7 errors).
