GICAR Water Level Controller
The water level control system consists of three electrodes. (HIGH and LOW water
level), and a reference electrode, all connected to the
GICAR
2DRLHG controller.
The long electrode which is continuously immersed in the water, acts as a reference and
is connected to ground.
The medium electrode (LOW level electrode) controls the water heaters. When it stops
sensing water, the
GICAR
controller stops the current to the water heaters. When it
senses water, the
GICAR
controller restores current to the water heaters.
The short electrode (HIGH level electrode), controls the water pump. When it senses
water, the
GICAR
controller stops the current to the water pump and simultanausly
closes water supply shut off valve. When it stops s ensing water, the
GICAR
controller
restores the current to the water pump and simultanausly opens water supply shut off
valve.
