Digital input terminal (CN1/2)
X15
Escalator
speed
detection
phase A signal
They are used for input of
escalator speed detection pulses
The MCTC-PES-E1 detects the
overspeed fault based on the
frequency or cycle of two pulses,
and detects the unintentional
reversal fault based on the pulse
phase.
1) Optical coupling
isolation, low level
input active
2) Input impedance:
3.3 k
Ω
3) Input voltage
range: 0–30 V
X16
Escalator
speed
detection
phase B signal
X17
Up step loss
detection
It detects the A/B pulses. If the
pulse counting exceeds the
threshold, the MCTC-PES-E1
judges that it is step loss.
X18
Down step loss
detection
It uses the same detection mode
as X17.
X19
Left handrail
speed
detection
If the MCTC-PES-E1 detects
that the handrail speed is 15%
lower than the actual speed of
the step, pallet or step chain
and the duration exceeds 15s, it
reports the handrail underspeed
fault.
X20
Right handrail
speed
detection
OP
X15 to X20
polarity
selection
When X15 to X20 are connected
to sensors of low level active,
OP is shorted to DC+. When
X15 to X20 are connected to
sensors of high level active, OP
is shorted to DC-.
Shorting OP and
DC+/DC- is effective
for X15 to X20 only.
Relay output terminal (CN4)
Y1/M1
Fault output
It becomes OFF when a fault
occurs. It is connected to the
system safety circuit with Y2/M2.
Rated voltage: 250
VAC
Rated current: 6 A
Y2/M2
It becomes OFF when a fault
occurs. It is connected to the
system safety circuit with Y1/M1.
Y3/M3
Aulixiary brake
output
It becomes OFF when 1.4 times
overspeed or unintentional
reversal running occurs. It is
connected with Y4/M4 to control
the auxiliary brake.
Y4/M4
It becomes OFF when 1.4 times
overspeed or unintentional
reversal running occurs. It is
connected with Y3/M3 to control
the auxiliary brake.
