Function Description Remark
Digital input terminal (CN1/2)
E24V
External +24 V
power supply
It is connected to the input
terminal 24V of the control
system when X1 to X4 are
connected with corresponding
signals of the control system in
parallel.
The switching-
mode power supply
complies with the
EN60950 standard.
X1
Normally open
(NO) inspection
signal
They are connected to
the inspection signal input
terminals of the control system.
When X1/ X2 becomes ON, the
related functions of the MCTC-
PES-E1 are disabled according
to GB standard.
1) Optical coupling
isolation, low level
input active
2) Input
impedance: 3.3 k
Ω
3) Input voltage
range: 0–30 V
X2
Normally
closed (NC)
inspection
signal
X3 Up signal
It receives the up signal of the
control system and is edge-
triggered.
X4 Down signal
It receives the down signal of
the control system and is edge-
triggered.
X5
Service brake
signal
It is connected to the auxiliary
contact of the service brake.
X6
Service
brake action
detection 1
It is connected to the action
switch of the service brake.
X7
Service
brake action
detection 2
It is used in the dual-motor
application. It is shorted with X6
in the single-motor application.
X8
Auxiliary brake
signal
It is connected to the auxiliary
contact of the auxiliary brake.
X9
Auxiliary
brake action
detection
It is connected to the action
switch of the auxiliary brake.
X10
Floor plate
switch 1
It is connected to the floor plate
switch. This signal must be
active during normal running
and can be inactive during
inspection.
X11
Floor plate
switch 2
It has the same function as the
X10.
X12 Reserved
X13 Reserved
X14
Manual reset
signal
It is used for manual fault reset.
The input becomes active after
the terminal keeps ON for more
than 2s and then keeps OFF
for more than 2s.
