3. Functions of monitor lamps
The pump is started by setting the main switch to the “Operation” position. When
the power switch is turned ON, all of the 3 lamps light up. If any one of the lamps
does not light up, the battery voltage is low or circuit has failed. Repair as required
in such a case. All of the lamps go out several seconds later.
At normal condition, all of the lamps are OFF while water is being discharged.
However, the lamps may light up when the self-starter motor is activated since the
battery voltage drops.
Monitor lamps keeping ON during pump operation or water discharge indicate
some trouble. Check and correct referring to the table below.
