5.5.2 Car Top Commissioning
Safety Information
◆
During car top commissioning, the operator stands on top of the car; to guarantee per-
sonal safety, ensure that car top inspection is enabled (inspection on top of the car takes
precedence over inspection in the equipment room).
◆
The MCTC-CTB is high level active by default.
This section takes the single-door (door 1) elevator system as an example to describe
the commissioning. The related signals include light curtain 1, door 1 open/close limit
signal, and door 1 open/close output signal, described in the following table.
Car top commissioning-related signals
CTB Terminal
P24 Common for X1 to X8 inputs
X1 Light curtain 1 input
X3 Door 1 open limit input
X5 Door 1 close limit input
BM Door 1 output common
B1 Door 1 open output
B2 Door 1 close output
For the double-door elevator system, the terminals controlling door 2 signals, such
as light curtain 2 signals and door 2 open/close limit signals, have the same principle
and monitoring mode as those of door 1. The details are not described here.
The system can monitor the input and output state of the light curtain and door ma-
chine signals and whether these signals are active.
■
You can view the signal indicators on the CTB to know the input/output state.
