8. CONSULTATION
The first two codes of the programmer
correspond to consultations of the unit state (C0 and
C1).
- Code C0: It shows the conductivity and pH
reading that reach the unit through the sensors.
If a breakdown takes place, the programmer
shows this code and the alarm origin
(programme number) intermittently, and the
reason for it (high or low conductivity, high or
low pH, breakdown input). For further
information read the section BREAKDOWNS.

- Code C1: It shows the percentage of fertiliser
injection, which has the highest proportion, as
well as the percentage of acid or base, which is
being injected.

9. PROGRAMMING
The codes that go from C2 to C7 are used to
define every programme, having to specify the
desired level of conductivity and pH, as well as the
relationship between the injection of the two
fertilisers.
Every code is divided into two sections. The first
one corresponds to values of conductivity or values
from the first fertiliser, while the second one
corresponds to values of pH or of the second
fertiliser. Press the “C” key to change section or
code and the “+” and “-“ keys to increase or
decrease the value of the section which is active, that
is to say the one which has a blinking point on its
left.
A point showed just after the code means that
the programme is activated.
- Codes C2, C3 and C4: Indicate the desired
reference value for conductivity (value from 0 to
9.9) and pH (value from 0 to 9.9) which is to be
reached when programme 1, 2 and 3 are
activated. The value 00 means that this part is
not to be regulated.

10. CONFIGURATION OF THE USER
In this section we can find the parameters
which allow you to adjust the working of the unit, as
well as the sensor calibration. To access this section,
press the “C” and “+” keys at the same time when
the programmer is at code C0 of consultation. If no
input is activated, the programmer goes to sensor
calibration; otherwise, it goes directly to the first
configuration code (code 04).
Press the “C” key to go from one code to
another. Use the “+” and “-“ keys to change values.
Press the “C” key until the code C0 appears to go
back to consultation.
Codes from 00 to 03, corresponding to
calibration are explained in the CALIBRATION
section.
- Code 04: EC high alarm. Indicate the value at
which the indicated reference has to be
surpassed (between 0 and 9.9) in order to
activate the alarm because the conductivity
level is too high.
- Code 05: EC low alarm. Indicate which value
(between 0 and 9.9) can be reached below the
desired reference in order to activate the alarm
because the conductivity level is too low.
- Code 06: pH high alarm. Indicate the quantity of
points (between 0 and 9.9) the indicated
reference can be surpassed in order to activate
the alarm because the pH level is too high.
- Code 07: pH low alarm. Indicate the quantity of
points (between 0 and 9.9) below the indicated
reference must be reached in order to activate
the alarm because the pH level is too low.
