Elkhart Brass UBEC 1AT AUTO TANK Fill System - Manual (Page 15)

15
During all modes of operation the TankVision display functions normally and the volume of water in
the tank is shown on the 9 LED display.
 All 9 LEDs are on when the tank is full. Each LED goes off starting at the top and working down as
the liquie in the tank decreases.
 The bottom two (2) LEDs flash when the tank is less than ¼ full.
 All 9 LEDs rapidly down-chase when the tank is almost empty.
Automatic Mode
Pressing and holding the AUTO button puts the system in the automatic mode and the green LED
comes on. The opening and closing of the valve is controlled by the control module on the control
valve. The valve stays closed until the tank water level goes below 50% or 75% (depending on your
system). The valve then opens fully and allows supply water to flow into the tank. When the tank is
refilled to approximately 95% or 100% (depending on your system) the valve will close. The valve takes
approximately 7 seconds to move from fully closed to fully open or from fully open to fully closed. The
valve cycles as needed during operations to maintain the water volume in the tank.
Manual Mode
Pressing the OPEN or CLOSE button puts the system into the manual mode and the MANUAL MODE
LED comes on. In the manual mode, the opening and closing of the valve is controlled by the OPEN
and CLOSE buttons.
Off (Valve Shut) Mode
Pressing the OFF button closes the valve.
The TankVision display functions normally and the volume of water in the tank is shown on the 9 LED
display.
VALVE POSITION INDICATORS
Solid Close – CLOSED LED is lit when valve is fully closed.
Solid Open – OPEN LED is lit when valve is fully opened.
Flashing Open – OPEN LED is flashing when valve is anywhere between fully open and fully closed.
OPERATIONAL CHECK
Note: For this check, the input to the AUTO TANK system control valve does not have to be connected
to a water source. The tank can be filled at the fill tower by any method that is convenient. (This will
check the operation of the AUTO TANK system, but it will not verify the plumbing between the valve
and tank)
1. Fill the tank with water and apply power to the AUTO TANK system.
2. Press the OPEN and CLOSE buttons.
Result: The valve and the indicating lamps follow the switch position.
3. Press the OPEN button to open the valve.
4. Press the AUTO button.
