Digital Output 2: Ready To Dispense
The ADM can be configured to prevent dispensing if the
conditioning zones are not the correct temperature. If
this feature is enabled, this bit will be low when at least
one temperature zone is not up to temperature.
NOTE: This bit gets pulled low during a dispense.
Digital Output 3: Dispense in Progress
This bit is high when a dispense is in progress.
Digital Outputs 4-7: Zone Conditioning On
When one of these bits is high, it indicates that the
respective heater/chiller in that zone is on.
Digital Outputs 8-11: Zone Temperature
Setpoint Rejected
This bit indicates the requested setpoint has been
rejected. This occurs when the requested setpoint is too
high or low. This bit should be checked after requesting
to change a setpoint to verify that the setpoint was
accepted.
NOTE: Changing the setpoint on the ADM does not
affect this bit.
Digital Outputs 12-19: Temperature
Conditioning Component Enabled
When one of these bits is high, the corresponding tem-
perature conditioning component is enabled.
