Power
Continuous green | Mains power connected |
Not illuminated | Mains power disconnected or hardware fault |
Status
Continuous green | Normal operation | Nb. If the Flow Gateway is in any state other than normal operation for more than 8 minutes it will automatically reboot |
Flashing orange | Network connecting | Attempting to establish a network (Ethernet) connection The Flow Gateway should not remain in this state for more than 10 seconds - if it does refer to the Network Link indicator |
Flashing green (1 second period) | Data link connecting | A network connection has been established, and is now attempting to connect to the Flow Coffee cloud servers (MQTT) The Flow Gateway should not remain in this state for more than 20 seconds - if it does the likely causes are:
|
Flashing red | Non-fatal error | The Flow Gateway has encountered an error condition, but is still running and will attempt to recover from the error To manually attempt to recover from the error restart the Flow Gateway by cycling the power. To do this remove the power plug, wait for all indicators to turn off (approximately 10 seconds), then reconnect the power plug |
Continuous red | Fatal error | The Flow Gateway has encountered a fatal error and cannot continue operating (ie. it has crashed) Nb. Although the Flow Gateway cannot continue operating when it is in this state, usually the subsystem which handles rebooting the Flow Gateway will still be able to restart the Flow Gateway after 8 minutes To manually attempt to recover from the error restart the Flow Gateway by cycling the power. To do this remove the power plug, wait for all indicators to turn off (approximately 10 seconds), then reconnect the power plug |
Not illuminated | Hardware fault | This state should not occur - contact your Flow Coffee representative for technical assistance |
Rapid flashing green | Flow Gateway is in configuration mode | This state should not occur - contact your Flow Coffee representative for technical assistance |
Grouphead 1-4 flow meters
Flashing green | Flow meter activity detected The rate at which the LED is flashing indicates the flow rate. Nb. At higher flow rates the LED can flash fast enough that it appears as being dimly illuminated |
Not illuminated / Continuous green | No flow meter activity detected Nb. It is normal for a connected grouphead's flow meter indicator to sometimes remain illuminated when the grouphead is not being used |
Continuous red | Incorrect connection to the coffee machine flow meter detected - The polarity (positive and negative) is reversed Check that the correct type of adaptors have been used for the coffee machine and that the plugs are connected in the correct orientation/polarity |
Network Link
Continuous amber | Network link layer connected - no network activity | Â |
Flashing amber | Network link layer connected - network activity | Â |
Not illuminated | Network link layer not connected | This state should not occur - the likely causes are:
|
Network Speed
Not illuminated | 10 Mbit/s connection speed |
Continuous green | 100 Mbit/s connection speed |
