[5] PL, PM, PH
Indicates present combustion detection status of the water level unit.
* Low fire : PL lamp is lit up.
* Medium fire : PM lamp is lit up(2.0 - 3.0 T/H).
* High fire : PH lamp is lit up
[6] Concentration Blowing-off Adjusting Method
This equipment is used to keep the electric conductivity of water in boiler uniformly and protect water pipe
from accuring of carry over, scale and corrosion.
By using this equipment, boiler can supply more stabilized steam for a long time.
The setting value is 3.7 at the normal condition on the dial indication which is setting the concentrated water
density. (Electrical conduction setting value is 4500
µ
s/cm2).
If resistance is over 4500
µ
s/cm2 electric conductivity of water, solenoid valve opened automatically and
concentrated water in pipe is drained if resistance will be downed under 2500~3300
µ
s/cm2, then solenoid
valve will be closed automatically
* Note:
1) The time indicated on the combustion time accumulation device is operated even in the power interruption by
the battery.
2) The battery is charged automatically when power on and can be used about 10,000 hours per one charge.
3) For time initiation(0000 hours, 00 minutes, 00 seconds), the reset switch inside is used.
(9) Concentration Blowing-off Device
This is a device for supplying high quality of
steam for prolonging the life of the boiler which
protects scales and carry over through blowing
off the boiler water automatically. When the
boiler water concentration is exceeded the
allowable range, the concentration blowing-off
sensor monitors it and its electrical signal is
flowed to the solenoid valve for blowing-off
following by open the valve and blow off the
concentrated water. When concentrated water
density is dropped down, the solenoid valve for
concentration water blowing-off is shut off and
stopped the exhausting the boiler water.
