Alert Display

For dredging operations certain dredging related alarms are available in the Alert Display. These show the data that are being monitored.
This page concentrates on those dredging alerts.

Dredging Result alerts are only available when Dredging System(s) are defined in the template database.
The values upon which the Alerts are based are entered in the Controller's Settings - Session Setup - Dredging menu.

Typically an Alert Display would also include other types of alerts:

• I/O Alert: Alert to check if data is being received or outputted by the QINSy computer.

• Raw Data Alert: Alert for raw observation data values received on the QINSy computer.

• Computation Result Alert: Alert for the results of computation observations.

Please refer to Help pages and to the Knowledge Base for information on these other alert types.

Alert Setup Type	Dredging Result
Design state	Above Design - Dredge head is located above selected design. On Target - Dredge head is located on selected design. Over Dredge - Dredge head is located beneath selected design. Not Used - No design selected or grid data is not available.
Intrusion Detection Error (Emergency Hoist)	If the horizontal distance or the vertical distance between the avoidance object and the dredge head is smaller than the tolerances entered in Controller - Settings - Session Setup - Dredging - Intrusion Detection an Error Alert is raised. Usually a Warning corridor is set first to indicate that you are nearing the Error corridor. OK - No cables or pipe lines within range of dredge head. Hoist - Dredge head is within range of cables and / or pipe lines. The dredge head is automatically hoisted (QINSy can send a flag to the dredger's PLC if interfaced. Otherwise the signal for hoisting must be triggered manually. Not Used - Intrusion Detection Error is disabled.
Poor Mixture Overboard (PMO)	Not applicable to Backhoe dredging operations.
Intrusion Detection Warning	If the horizontal distance between the avoidance object and the dredge head is smaller than the tolerances entered in Controller - Settings - Session Setup - Dredging - Intrusion Detection a Warning Alert is raised. Usually the Warning corridor is set around the Error corridor.
System	With all four alert types choose which Dredging System to monitor.
Dredge Head	With all four alert types choose which Dredge Head is monitored.
