7
- Code 08: Delay in the EC alarm detection.
Indicate the number of seconds during which
conductivity must be at an alarm level before its
activation. The value must be between 0 and
999.
- Code 09: Delay in the pH alarm detection.
Indicate the number of seconds during which
pH must be at an alarm level before its
activation. The value must be between 0 and
999.
- Code 10: Pre-agitation. Indicate the number of
seconds during which the agitator must be
working before injection is started. The value
must be between 0 and 250.
- Code 11: Agitator working. Indicate the number
of seconds the agitator must be working in the
agitation cycles, which take place during the
fertilisation. The value must be between 0 and
250.
- Code 12: Agitator at stop. Indicate the number
of seconds the agitator must be at stop in the
agitation cycles, which take place during the
fertilisation. The value must be between 0 and
250.
- Code 13: Alarm working. Indicate the number of
seconds the alarm must be working in the cycle
of alarm signal. The value must be between 0
and 250.
- Code 14: Alarm at stop. Indicate the number of
seconds the alarm must be at stop in the cycle
of alarm signal. The value must be between 0
and 250.
11. CALIBRATION
In the configuration of the user, codes from 00
to 03 are used to calibrate sensors. On entering in
everyone of the codes, the code and value which is
expected from the sensor appears for a few
seconds. After these seconds, the screen blinks and
displays the reading, which is being obtained from
the sensor. If the reading is stable enough and
similar to the desired one, the screen stops blinking,
indicating that the sensor has been calibrated. If you
press the “+” and “-“ keys simultaneously the unit is
forced to accept the value which is displayed at this
moment.
If the calibration of sensor is not to be done,
press the “C” key during the initial seconds or press
the “C” key until the code changes, when the screen
is blinking.
In order to have a good calibration, the sensor
and the liquid have to be as close as possible to
25ºC degrees. Then, the liquid value and the
automatic compensation that the sensor have will be
correct. If the irrigation water is cooler than 25ºC the
sensor it should be taken out for several minutes
because the sensor has and inertia to the
temperature changes.
The calibration codes go in pairs. So, codes 00
and 01 are used to calibrate the conductivity sensor,
while codes 02 and 03 correspond to the calibration
of the pH sensor. If a suitable calibration is not done
in the first code, the second one does not appear.
So, to do a valid calibration of the sensor, it is
necessary to do the two codes, which correspond to
the sensor correctly.
12. BREAKDOWNS
When the unit detects a breakdown, because a
non desired level of conductivity or pH has been
reached or because input 4 has been activated, the
programme stops automatically and injection also
stops. The screen displays the consultation code C0
and the information about the reason of the
breakdown in a blinking way. The programme will
not be started again until, the breakdown is not
deactivated by pressing the “C” key.
