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.
Sensor Fault Alarm
This alarm is triggered when the Hydro-Control detects a problem with the RS485 communications
with the sensor.
Check:
•
Ensure that communications cables are routed away from heavy duty power cables and
electrical equipment.
• 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.
