4. Advanced Operation
•
Water Meter No.:
The number of water meter according to which the proportional fertilization
is calculated.
•
Fert. Fail.React *:
The options are:
Continue, Stop.
•
EC/pH Constants:
o
EC Sensor No.:
The number of the sensor measuring the EC.
o
pH Sensor No.:
The number of the sensor measuring the pH.
o
Measure Delay – Sec:
The number of seconds at the beginning of irrigation during which
the EC/pH measurement is not carried out. The EC/pH correction is carried out during this time
according to previous data.
o
Change Delay – Sec:
The cycle of time during which the correction is carried out.
After the controller changes the % of correction for the EC/pH it waits for this period of
time before analyzing the reaction to the correction and making a further correction.
•
Auto Cancel Alarm (Yes/No) *:
See “Alarm Setup.”
EC-pH Faults (1432):
Press “EC-pH Faults” in the “Fert Center Consts – 143” to access the
“EC-pH Faults Setup – 1432” screen.
Screen Explanation:
There are two types of alarms: EC/pH for an alarm that only stop the
fertilization and a more severe alarm that totally stops the irrigation. For each of these alarms
the following parameters must be set. (The above screen picture shows the default setup). The
parameters are:
•
EC/pH Low Deviation
(2 parameters)
:
When the reading is lower than the target by more than
this parameter (after the alarm delay) an alarm is issued.
•
EC/pH High Deviation
(2 parameters): When the reading is higher than the target by more than
this parameter (after the alarm delay) an alarm is issued.
