Difference between calculated and measured dosing channel flow.
Example: Dosing Channel 1 defined by technician as 100liter/hour, but if
the system measured less than 75liter/hour or more than 125liter/hour,
an alarm will be generated.

Number of missing pulses before the system will generate a No Flow
alarm. The system calculates the expected time between pulses of water
meter and if a certain time elapsed without receiving the desired number
of pulses, then generate an alarm.
Number of consecutive flow alarms of the same type (high flow, low flow
etc') but different valves before the system is stopped. Example: High flow
at valve 1 ->High flow at valve 2->High flow at valve 3 = 3 consecutive
High flow, then system stops.
Number of irrigations given without measuring drainage, above which an
alarm will be generated. Common reasons: Irrigation quantity is too small
so there is not enough drain or drain measurement malfunction because of
technical problem.
Minimum system pressure before generate an alarm.
Number of short circuit (in field device) alarms measured before the
system is paused.
Define the A/D threshold value to be considered as a short circuit (For
technician use only).
Define the A/D threshold value to be considered as a short circuit for
Extension box no. 1 (For technician use only)
Define the A/D threshold value to be considered as a short circuit for
Extension box no. 2 (For technician use only)
Define the A/D threshold value to be considered as a short circuit for
Extension box no. 3 (For technician use only)
