INTELLIGENT MONITOR
™
POWER
OPERATION
This unit is to be powered using +12V DC. The power unit is a wire tail with 2.5mm, center positive barrel jack.
The Intelligent Monitor
™
has a battery backup that uses 3 AAA size batteries. The battery holder is part of the
Monitor Assembly located inside the Umbrella Cap on the top of the System. It can be accessed by lifting the
Umbrella Cap from the System. Battery life will vary based on water flow when running on battery mode and
type of batteries used. With high continuous flow, the batteries are expected to last approximately 14 days.
With no flow, the batteries are expected to last approximately 6 months.
The Intelligent Monitor
™
keeps track of the gallons of water that pass through the System. The Monitor is
removable for inspection and cleaning. Make sure water is bypassed or turned off when removing the Monitor
for maintenance. The Monitor has a three pin plug that connects to the electronic board in the Umbrella Cap.
LEDs
Simple color-coded LED notifications display the usage status of the filter cartridge:
GREEN
100%-10% of filter life remains
YELLOW
Under 10% of filter life remains
RED
End of filter life has been reached
If there is flow, LEDs should alternately blink in the following pattern: 1-2-3-2 (repeat). The frequency that the
LEDs blink corresponds to the flow rate received from the Monitor. For every revolution from the Monitor,
the LED pattern should be incremented to turn off the next LED. If there are no revolutions for 2 seconds, all
LEDs will turn on solid.
If the batteries are low, the middle LED will turn WHITE. The battery level is checked once an hour to
minimize the battery drain from checking the voltage.
Reset Button
The Reset Button allows for the Intelligent Monitor
™
to be reset.
To reset the Intelligent Monitor
™
, press and hold the Reset Button for 3 seconds. Once reset, the LEDs should
flash green 3 times to confirm reset.
Power Monitoring and Battery Mode
In addition to monitoring water usage, the Intelligent Monitor
™
also monitors the System’s 12V DC power
and battery power. If there is a power failure and no batteries are installed, the Monitor’s value will be saved
to non-volatile memory. When power is resumed, the gallon count will resume from where it left off when
power was lost.
If there is a power failure and batteries are installed, the Monitor goes into battery mode. During battery
mode, the LEDs should shut off. If the Monitor is in the YELLOW or RED state, or if the battery voltage gets
low, the LEDs will flash on in the appropriate color for .125 seconds every 4 seconds. If the Reset Button is
pressed in battery mode, the LEDs will turn on for 4 seconds and then return to battery mode.
