1.2 Operation with External Control Signal (External connection is required
separately)
1.2.1 Stopping All the Boilers
All the boilers can be stopped by entering control signals to the all stop input terminal.
With external all stop operation, the “Lump operation” LED turns on and then the boilers under
automatic operation
(*)
stop combustion in order.
1.2.2 Firing Up All the Boilers
All the boilers can be fired up by entering control signals to the all combustion input terminal. With
external all combustion operation, the “Lump operation” LED turns on and then the boilers under
automatic operation
(*)
start combustion in order.
1.2.3 Suspending Alarm Output
The Pressure Controller MP1-200 has alarm outputs to connect a buzzer or other purposes. The
output contact closes in case of abnormality. To stop this output, press the “DISPLAY CHANGE”
switch or perform alarm check operation from outside to the alarm check input terminal (internal
terminal block No. 4 and No. 5).
NOTE

Any boilers which have been stopped by the MI Terminal MT1-200 will not perform
combustion.

Any boiler whose boiler steam pressure exceeds the steam pressure setting (high)
or whose combustion SW or operation switch is turned off will not perform
combustion.

All combustion is impossible during all stop or emergency stop input.
NOTE

The boilers under manual operation
(*)
will not stop.

If the MI Terminal MT1-200 is installed with the optional pressure sensor, all stop
operation cannot stop the boiler under automatic operation(*) from performing
combustion until the standby pressure is reached.
