Mitsubishi Elevator Landing Door & Car Door Bypass Device P266006B000G01L01

P266006B000G01L01 is commonly used in Mitsubishi elevator maintenance and safety bypass systems.

This device is generally associated with:

• landing door bypass operation
• car door bypass function
• maintenance inspection mode
• safety circuit temporary bypass

Usually installed inside Mitsubishi controller cabinets or maintenance operation circuits.

Application Situation

During elevator inspection or troubleshooting work, technicians may use the bypass function for:

• door circuit testing
• maintenance running mode
• controller inspection
• fault diagnosis operation

In some modernization projects in Croatia and Thailand, older Mitsubishi systems still use this type of bypass module during maintenance procedures.

Practical Field Notes

This device is not part of normal passenger operation.

Normally only used by:

• maintenance personnel
• commissioning engineers
• troubleshooting technicians

Improper bypass operation may affect normal safety protection logic.

Because of this, some service companies replace aging bypass modules during controller refurbishment projects.

Common Maintenance Situation

Technicians sometimes inspect this module when:

• bypass signals fail intermittently
• inspection mode becomes unstable
• door safety circuits cannot reset normally
• maintenance operation behaves abnormally

In some older control cabinets, terminal oxidation may also affect bypass signal stability.

Installation Attention

Before replacement:

• controller generation should be confirmed
• bypass wiring layout must match original structure

Some Mitsubishi systems use different bypass logic depending on controller series.
