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

Item Description
Missing Pulses For No
Flow
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.
Stop System
Consecutive Flow
Alarms
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.
# of Irrigations Without
Drainage
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.
Low Pressure Alarm
(bar/psi)
Minimum system pressure before generate an alarm.
Num. Of Short Circ. To
Pause
Number of short circuit (in field device) alarms measured before the system is paused.
Short Output Level (60-
350)
Define the A/D threshold value to be considered as a short circuit (For technician use
only).
Short O. Level EXT1
(60 – 350)
Define the A/D threshold value to be considered as a short circuit for Extension box no. 1
(For technician use only)
Short O. Level EXT2
(60 – 350)
Define the A/D threshold value to be considered as a short circuit for Extension box no. 2
(For technician use only)
Short O. Level EXT3
(60 – 350)
Define the A/D threshold value to be considered as a short circuit for Extension box no. 3
(For technician use only)
