Error #150: High Regulated CO PSI
The regulated CO pressure is above 70 PSI (483 kPa).
Error #160: Low Line Voltage
The voltage supply is below 200 volts.
Error #170: High Line Voltage
The voltage supply is above 254 volts.
Error #180: LPSI Transducer
The low side refrigeration pressure is not reading correctly.
Error #200: Return Temperature Sensor
The refrigeration return (suction) temperature sensor is not reading correctly.
Error #270: Air Out
The compressed air pressure is less than 45 PSI (310 kPa).
1 Ensure the pressure transducer is plugged in.
2 Replace the transducer if faulty.
1
Install a boost transformer or Automatic Voltage Regulator (AVR). Even if the voltage is slightly
above 200V, a boost transformer or AVR may be needed as uctuations in power during the day,
or during dispenser operation may cause it to drop below 200 volts and shut down the dispenser.
Note: For optimal performance and to avoid component failures, FBD recommends dispenser be
supplied with 230 VAC ± 10%.
1
Install a buck transformer or Automatic Voltage Regulator (AVR).
Note: For optimal performance and to avoid component failures, FBD recommends dispenser be
supplied with 230 VAC ± 10%.
1 Check the “carbonation” regulator on the header tray and ensure it is set to 60 PSI (414 kPa).
1 Verify there is a supply of compressed air.
2 Ensure the compressed air shuto valve at the back of the dispenser is not turned o.
3 Ensure the gas pressure transducer is connected and working properly.
4
Ensure the compressed air supply pressure at the dispenser is reading 70 PSI (483 kPa). Adjust the
regulator if needed.
1 Ensure the temperature sensor is plugged in.
2 Replace the sensor if faulty.
