Alarm Configuration Chapter 9
58 Hydro-Control VI Operators Guide HD0456 Rev 1.7.1
Cement In Alarm
This alarm is triggered if the ‘Cement In’ input signal is not received within the time defined by the
‘Cement Timeout’ parameter in the Recipe after the ‘Pre-Wet Done’ output signal is set.
Check:
• Cement is feeding from the cement silos.
• The control system is sending the “Cement In” signal to the Hydro-Control correctly and
within the timeout. If the control system does not send the Cement In signal then the
timeout in the recipe should be set to zero.
Water Meter Fault Alarm
This alarm is triggered if a water valve has been opened and the water meter has not pulsed within
the time set by the ‘Water Meter Timeout’ parameter defined in the System Parameters pages.
Check:
•
The operation of the water valves.
•
The water meter operation. To check the input go to the I/O setup screen shown in Figure
31 and ensure that the water meter counter increments when the water valves are opened.
Leaking Water Valve Alarm
This alarm is triggered if the water meter pulses when both of the water valves have been closed
for more than 5 seconds during the dry and wet mix phases.
Check:
• The valves to see if they are leaking.
•
The water meter is working correctly.
Waiting For Tank Fill Alarm (Only available if Expansion Board is fitted)
This alarm is triggered if the Hydro-Control has reached a water addition stage when using weighed
water and the Water Tank Full input has not been received.
Check:
• Water tank filling should be investigated. It may be filling slowly or not at all. If needed
then the mix times, or the time between mixes should be lengthened to allow the water
tank time to fill.
No Water Required Alarm
This alarm is triggered in CALC Mode if the calculation has determined that no water is needed as
the dry mix moisture is already at or above the target for the recipe.
Check:
• The moisture level of the incoming aggregates.
•
Reduce any Pre-wet water that is added. If no Pre-wet water is being added, then
consideration of the aggregate handling and storage is advised.
