1. After a chiller has been switched.
2. After CO2 pressure has been changed.
3. To utilize FOB Mode properly.
※ Because the flow rate measured through PRESET Mode is used in FOB Mode, the flow rate must be measured with proper discharging of beer.

FOAM
Before : 3 times
• Before : 3 times While blinking, press the up and down button to choose from “After : 5 times” to “Before : 5 times.”

• Disable : Deactivates foam generation.

8. FOB FOB Warning! ON : Start OFF : Stop Basic Functions Detector : ON
FOB Mode (Foam On Beer Detector)
When a keg is empty or just replaced, beer discharge would not be normal having foam burst out. The FOB Mode prevents this from happening. The flow rate would be faster than usual when foam is about to burst. The FOB Mode of ReverseTap detects this change and shut down the valve to prevent foam from popping.
FOB
Detector : ON
Flow rate x 1.30
• The example screen shown above shows that the FOB Mode will be activated and shut the valve when the flow rate exceeds 1.3 times more of its usual rate.
• ON/OFF : While blinking, press the Up and Down button to choose whether to use/not use this function. • Flow rate Coefficient: While blinking, input the coefficient number. (Default : 1.30)
• When foam bursts while using ReverseTap, FOB Mode is activated with the screen shown below.
FOB
Warning!
ON : Start
OFF : Stop
Warning screen
Asking FOB Mode ON/OFF
• If the FOB Detector is ON and it still cannot detect a foam popping, adjust the coefficient lower than 1.30.
• If “FOB Warning” screen appears even though the keg contains a lot of beer, adjust the coefficient higher than 1.30.
• Press the START button to continue FOB Mode turned ON.
• Press the STOP button to turn off FOB Mode.
• Things to do when “FOB Warning” is up.
