Alarm Configuration
Max Dry Mix Time Exceeded Alarm
Max Wet Mix Time Exceeded Alarm
These alarms are triggered when the Auto-track is running and the sensor reading has not
stabilised within the configured Auto-track values before the end of the Dry Mix and Wet Mix Times
set in the recipe.
Check:
• The Auto-track control settings are set correctly. The frequency this alarm is triggered can
be reduced by decreasing the Auto-track Mix Time or increasing the allowed Mix Deviation,
either in the recipe or the system parameters.
The recipe mix time parameters are set to be long enough for the mix to stabilise.
•

Ensure cables are of the required standard

Ensure that the cable screen is connected at the sensor end only.

Further information on cabling can be found in the sensor user guides.
