We’ve just finalized the corrected and revised manual for Xizi Otis elevator systems.
Fault codes are your primary diagnostic tool. Here are key codes, many of which appear on Xizi Otis‘s 21VF, MCS321, TOEC2000, and 300VF systems.
: Before normal operation, a DCS (Door Check Sequence) must be performed floor-by-floor from bottom to top to confirm door safety integrity. xizi otis elevator manual fixed
Navigate to the menu path to view operational status.
Use a multimeter to measure continuity across the safety loop contacts (terminals 110V/X10). Replace pitted or oxidized contact switches. 3. Leveling and Position Loss Faults (e.g., Code 302) We’ve just finalized the corrected and revised manual
Run the car up and down the hoistway on Inspection Mode to listen for unusual mechanical sounds.
Call the OTISLINE 24/7 service line at 1-800-233-6847 1.2.2 for emergency assistance 1.2.1 . : Before normal operation, a DCS (Door Check
Inspect the braking resistors. Use a multimeter to measure the resistance across the dynamic braking terminals. An open circuit or incorrect resistance value prevents excess energy dissipation during down-travel deceleration.
Check the incoming three-phase power supply (R-S-T). Ensure all phase voltages are balanced within ±10% and that the main contactors are not suffering from pitted or carbon-crusted contacts. 4. Resetting the Safety Chain and Run Faults
The following common faults and solutions are provided:
Keep the system in Inspection Mode for 2 minutes to allow peripheral nodes to re-establish synchronous communication. 3. Fixing Common Mechanical and Electrical Faults
