Chapter 2 Installation and Wiring

The precautions on electrical wiring are as follows:
1） All input signals are low level active.
2） E24V is connected to the 24 V power supply of the escalator control system. DC+/DC-
is connected to the switching-mode power supply of the MCTC-PES-E1. The X1 to X4
terminals are connected to the 24 V power supply of the escalator control system and
cannot use the power supply of the MCTC-PES-E1.
3） X1, X3 to X9 and X14 are NO signals by Factory Setting, while X2, X10 and X11 are
NC signals by Factory Setting. The NO/NC feature of X1 to X5, X8 and X14 cannot be
modified.
4） Because X1 is NO and X2 is NC, you need to install an NC relay before X1. The wiring
method is shown in Figure 3-8. If X1 and X2 open or close simultaneously, the MCTC-
PES-E1 reports a fault.
Caution
◆
The inspection signal connecting to the relay before X1 and that connecting to X2 must be
obtained separately from the inspection switch and cannot share one cable.
5） If there is no auxiliary brake, short X8 and X9 to 0V. If the service brake uses an
inspection switch, short X6 to X7.
6） If the floor plate switches have the compulsory break-off function, the function of X10
and X11 can be disabled. In this case, X10 and X11 must be active, which can be
implemented by shorting them or modifying their NO/NC feature.
7） OP is active only for X15 to X20. For low-level active signals (NPN output), short OP to
24V. Otherwise, short OP to 0V.
2.3.3 Connecting the Floor Plate Switches
The system can detect opening or removal of the floor plate. If the floor plate detection
function is enabled, a total of four floor plate switches are required. The top machine room
and bottom machine room respectively need to install two detection switches. The following
figure shows connection between the four detection switches and the system.
