b) Check if the setting of the boiler pressure is lower than the control pressure.
Set the pressure of the boiler pressure 0.1 MPa {1.0 kgf/cm
2
} higher than the control
pressure.
4. When the Boilers Do Not Start Combustion
a) Check if the boiler's operation switch or combustion switch are turned on.
The boiler does not start combustion unless the boiler's operation switch and combustion
switch are turned on. Turn on the boiler's operation switch and combustion switch in
accordance with the boiler's operation manual to make the boiler ready for combustion.
b) Check if the “TIMER” LED of the MI Terminal MT1-200 is blinking.
When the “TIMER” LED is blinking, the boilers are stopped with the timer function.
Press the “TIMER” switch to cancel the timer function or change the timer setting.
P. 20, 28
c) Check if the “LUMP OPERATION” or “EMERGENCY STOP” LED of the Pressure Controller
MP1-200 control panel is turned on.
The boiler does not start combustion when control signals are input to the all stop or
emergency stop terminal for external control. Turn off the switches provided outside to
cancel the boiler stop input.
If an earthquake detector is connected to the unit, the detector may be in the detecting
process.
Check the cause and then perform resetting.
P. 9, 41
5. When the “B.BLOW” or “S.BLOW” LED Does Not Turn on at All or
Turns on Frequently
a) Check if the complete blowdown/soot blow time of the MI Terminal MT1-200 is set properly.
If the complete blowdown/soot blow notification timing is set to 0, no notification will be set
off.
The notification timing is set by hours. Check for proper setting.
