1. PRECAUTIONS REGARDING INSTALLATION
Pay significant attention to the precautions below when performing installation or instrumentation.
(1) The ground wire must be connected to the ground terminal inside the power panel. The diameter of
the electric wire to be used must be equal to or more than that of the power supply wire.
(2) Do not install any overcurrent circuit breakers to the grounding wire.
(3) Ensure that a dedicated earth leakage circuit breaker (with overcurrent protection) has been
installed when wiring the main power supply from the power panel.
(4) Ensure that the insulation resistance of the main power wire is equal to or more than 0.1 MΩ.
(5) When wiring from the power panel, the wire diameter for power supply must be equal to or more
than 2.0 mm2 （AWG14）.When wiring the power supply of MT1-200 from the boiler control panel, the
wire diameter must be equal to or more than 0.9 mm2(AWG18).
(6) Do not extend the steam pressure sensor cable.
(7) Ensure that the distance of communications wiring does not exceed 300 m.
NOTE) Follow all code and local regulations as your instruction .

3. COMPONENT NAMES
3.1. Components of Display Control Panel
(a) MP1-200
(b) MT1-200
It turns ON when the steam
pressure becomes the set value
of pressure alarm H or more. At
this time, the contact of pressure
alarm H output turns ON.
HIGH-PRESSURE LED
It turns ON when the steam
pressure becomes the set value
of pressure alarm L or less. At this
time, the contact of pressure
alarm L output turns ON.
LOW-PRESSURE LED
It turns ON when the circuit
between external control input
terminals 2 and 3 is shorted. At
this time, the boilers that are
under normal communication
conditions are stopped regardless
of pressure and manual/automatic
mode.
EMERGENCY STOP LED
It turns ON when the circuit
between external control input
terminals 7 and 8 (all stop) or
between 6 and 7 (all combustion)
is shorted.
LUMP OPERATION LED
It is used to change the display
items on the 4-digit LED.
When the external output “alarm”
is ON, press it. The output turns
OFF.
DISPLAY CHANGE switch
It turns ON if any of the buzzers
for the boilers under MI control is
activated.
At this time, the external output
“boiler trouble” turns ON.
BOILER TROUBLE LED
It turns ON if an abnormality of
pressure sensor is detected. At
this time, the external output
“sensor fail” turns ON.
SENSOR FAIL LED
It turns ON if the CPU is not
correctly operated due to voltage
fluctuation, circuit failure, etc.
