Perform after the pump assembly or the driver board is replaced.
Method 1:
1. Enter programming mode: Press the Prime button for 2 seconds followed by
the Clean button for 2 seconds.
•
“Program Mode: 1” should be displayed on the LCD on the dispenser
front.
2. Remove the back panel from the dispenser by removing the 8 screws.
3. Select the pump for the Flavor required.
4. Press Hidden Button 1 (See page 4) on the Button Panel.
Within 3 seconds, press and hold either of the driver push buttons (the
Reverse Button over the Red LED or the Forward Button over the Green LED)
on the pump driver circuit board.
The driver red LED should flash to indicate the new address it has stored for
that pump, e.g. one flash for pump one, two flashes for pump two, etc.
•
If this period is longer than 3 seconds, the pump will not re-address.
Repeat Step 4.
5. Continue to hold the push button until the number of flashes matches the
pump location, then release.
6. Verify by pressing the Flavor button for the pump that has just been re-
addressed. Watch to ensure that pump lead screw moves and only the lead
screw for that pump.
The pump position is re-addressed.
Method 2 (Manual Method):
NOTE: flavor may be dispensed during this procedure, so place a catch cup to
contain it.
1. Remove the back panel from the dispenser by removing the 8 screws.
2. Select the pump for the Flavor pump to be addressed.
3. On the circuit board for the pump driver to be addressed:
- press and hold the left black button (the Reverse Button over the Red
LED)
- while the left button is depressed, press and hold the right button (the
Forward Button over the Green LED)
NOTE: keep both buttons depressed during the entire procedure.
- the red light in the upper right corner will start to flash 1 second later. The
number of flashes indicates the address of the pump: e.g. one flash for
pump one, two flashes for pump two, etc.
- release buttons after the correct number of flashes for the pump you are
re-addressing (One second later, the board will re-verify the address
with the number of blinks for that pump, e.g. 3 blinks for pump 3)
4. Verify by pressing the Flavor button for the pump that has just been re-
addressed. Watch to ensure that pump lead screw moves and only the lead
screw for that pump.
