OPERATION

e) Holding-pressure setting (Option: Only when pressure sensor is installed)
This setting provides standby pressure under automatic operation
(*)
. The boiler fires up until the
boiler steam pressure reaches the pressure set in this section regardless of the header steam
pressure. Set the pressure lower than (the value obtained by subtracting the control range from
the control pressure) specified at the Pressure Controller MP1-200.The boiler is on standby
above a constant pressure, enabling stable response at a sudden load change.
Set the same unit as that of header steam pressure.
P.19
1) Press the “SELECT” switch as many times as
needed to display the holding-pressure
setting.
2) Press the “UP” and “DOWN” switches
simultaneously, and then the set value starts
blinking.
3) Press the “UP” or “DOWN” switch to set the
desired pressure.
4) Press the “SELECT” switch to finish the setting.
f)
Differential setting (holding) (Option: Only when pressure sensor is installed)
After boiler combustion is stopped at the pressure specified in the previous section, combustion
starts again when the boiler steam pressure decreases by the specified differential set in this
section.
Set the same unit as that of header steam pressure.
P.19
1) Press the “SELECT” switch as many times
as needed to display differential setting
(holding).
2) Press the “UP” and “DOWN” switches
simultaneously, then the set value starts
blinking.
3) Press the “UP” or “DOWN” switch to set the
desired pressure.
4) Press the “SELECT” switch to finish the setting.
