Flip the INS switch on the main control board to prevent the elevator from responding to hall calls during boot-up.
Elevator systems will completely lock out if the safety loop detects an open circuit while running.
If you have more details such as the model number, type of elevator (e.g., hydraulic, traction), or the country it was installed in, it could help narrow down the search. Additionally, specifying if "fixed" refers to a particular issue or version can assist in getting more precise assistance. xizi otis elevator manual fixed
No DOL (Door Open Limit) signal received. Clean door tracks or inspect the door operator motor. Position Count Error

: Xizi Otis units incorporate redundant systems like emergency stop buttons, safety brakes for overspeed, and handrail speed monitors.
Test voltage drops across the brake coil during startup to ensure it receives full picking voltage before dropping to holding voltage. Load Weighing Calibration Additionally, specifying if "fixed" refers to a particular
The OCSS (Operational Control Sub-System) cannot operate due to a critical driver fault.
Fault code tables differ significantly between OH-CON and LCB variants.
Use the hand-held Service Tool to navigate to the fault menu ( M-1-2-1 ) and clear the logged errors.
Which (e.g., OH-CON, RCB-II) is installed?
