Construction Mode

Before You Begin

Review the following warnings and become familiar with this manual section before beginning
work.
Danger
This equipment contains voltages of up to 1000V, rotating motor parts, and driven machin-
ery. The combination of high voltage and moving parts can cause serious or fatal injury.
Only qualified personnel who are familiar with this manual and driven machinery should
attempt to start up or troubleshoot this equipment. Please observe the following:
• USE EXTREME CAUTION — Do not touch circuit boards, resistors, or motor electri-
cal connections without ensuring that the unit is properly grounded and no high volt-
age is present. Do not apply AC power before grounding the equipment in accordance
with applicable local codes, the job prints, and instructions contained in this manual.
• BE CERTAIN that any possible violent motion of the motor shaft and driven machin-
ery, caused by improper control operation, will not cause personal injury or damage.
Peak torques of up to ten times rated motor torque can occur during a control failure.
• HIGH VOLTAGE may be present on the motor and drive whenever AC power is
applied, even if the motor is not rotating.
• BEFORE BEGINNING WORK, read these instructions all the way through to become
familiar with the procedures. Proceed cautiously. These instructions assume adequate
electrical troubleshooting experience. Follow the procedures carefully and, if the eleva-
tor does not respond correctly, check the circuits and obtain necessary assistance.

Overview of Construction Mode

Construction mode operation allows the car to be run on Machine Room Inspection and Cartop
Inspection with a bare minimum of field wiring installed. For Construction Mode operation,
only the following are needed to run the car:
• Motor, brake, and drive
• Velocity encoder/tachometer
• Safety String
• Normal limit switches
• Door locks and door position monitor (if used)
• The Construction Mode option (iView/Safety screen or iBox/Controller Setup/Safety/
Construction Mode) must be enabled to run the controller in Construction mode.
The cartop wiring interconnect box (iLink) is not required for Construction mode operation.
Instead, temporary wiring may be used to "bypass" the cartop safety string.
