Most modern Xizi Otis elevators use a controller board often labeled as the or a proprietary Xizi-Otis variant (often based on the Otis GECB or similar architecture).
While many issues can be fixed by qualified in-house technicians, any work related to the safety circuit, motor drive, or governor should be handled by qualified .
Position reference problems constitute one of the trickiest diagnostic categories. These errors occur when the elevator cannot accurately determine its location in the hoistway: xizi otis elevator manual fixed

: A calibration process where the system learns the elevator's path. Fault messages are displayed on-screen if the system detects obstructions or sensor errors during this run. Manual Brake Release Most modern Xizi Otis elevators use a controller
Before changing EEPROM values via the service tool, document the original hexadecimal variables found on your specific wiring diagram sheet.
Manually inspect the door hanger rollers and the interlock contacts on the affected floor. Clean dirt, dust, or debris out of the sill grooves that might prevent the door from fully closing. Adjust the mechanical lock clearance if it falls outside the 1–2mm manual specification. Fault Code: E20 (Levelling Sensor Error) These errors occur when the elevator cannot accurately
Common Mechanical and Electrical Tasks in Manual Fixed Mode 6.1 Mechanical adjustments: guide rail lubrication, roller/brush replacement, door closer adjustments, guide shoe replacement. 6.2 Brake servicing: test brake release/engage under no-load and light-load conditions; measure air gap and lining thickness; record torque/current curves. 6.3 Controller diagnostics: read fault memory, monitor I/O while in manual mode, check encoder/ resolver feedback continuity. 6.4 Safety device tests: overspeed governor trip test (per OEM and code), door lock monitoring, emergency stop verification.
Understanding the interface of the Service Tool (Server) is the first step to executing a manual fix. The manual organizes operations into three main menus: , Test (2) , Setup (3) , and Tools (4) . Step-by-Step Fixes for Common Xizi Otis Faults 1. Clearing TCI Lockouts (Inspection Faults)
: After major maintenance or if positioning is off, the system may require recalibration.
