Turning The Power On To The Dispenser; If System Looses Power; Battery Override Switch; Testing The Battery - Bennett 3000 Series Service Manual

Turning Power "On" to the Dispenser
The dispenser power must be turned on from the breaker panel.
Locate the breaker panel that serves the dispenser that you want to turn on.
Move the breaker to the "On" position. You should see the display displaying the last sale on each CPU
and auxiliary display. See figure 1. If there has been no sales, all 000's will be displayed. See figure 2.
Fig. 1 - Normal display
If the system experiences a power fail, there are batteries on the CPU board that will display the amount
of the last sale in progress at the time of power loss, and will alternate with the power fail message for
15 minutes (or unless the battery is over-ridden). After 15 minutes the display goes blank and stays that
way power is restored.
When you turn power off to the dispenser and you see the power fail message (all PPP's), and you do
not want to wait 15 minutes until the display goes blank, you can over ride the battery by pressing the
battery over ride switch located in the center of the CPU board on the backside. You should not perform
service work until the battery is off. Press this button and hold it for 1 second and this over-rides the
battery. See Fig. 4

888's on
power failure to the system.
The only way to test the back up battery is to turn power off to the system. It should hold the display up
for 15 minutes. If it does not, it could be because this is a brand new dispenser and needs 24 hours to
fully charge. If not, the batteries cannot be replaced, the entire CPU must be replaced.
