Remote control
The fertilizer outputs are linked to the A channel and the acid control to the B channel. Then the fertilizer can be switch on /
off independently to the acid, and the PI parameters too.
Alarm:
The refrence value for the EC alarm is the EC set point.
Pumps configurationss
1x Multifertic 2 heads with 2 servos, 2x Dostec, 1xDositec.
Example 1:
Outs 1,2,3: Modular pump for a proportional addition of 2 products (out 2 and 3)
Proportionality out 2: 0.200%
Proportionality out 3: 0.300%
Out 4: Dosing pump for and addition of a product acording to an EC set point.
EC set point out 5: 2.50mS
Out 5: Dosing pump for a proportional addition of one product
Proportionality out 5: 0.100%
Out 6: Dosing pump for a pH control.
pH set point out 6: 6.5

Programming
4.3 . ERRORS REGARDING THE PROGRAMMING.
Errors referred to EC Programming:
-Only one EC Set Point is possible
-If there is any Output configured as P (Proportion), an Ec Set Point must have been introduced.
If Control Outputs configured as P (Proportion) are Servo Outputs (S) the EC Set Point must be introduced in
the V Output.
If Control Outputs configured as P (Proportion) are independent analogue Outputs (A) the EC Set Point must
be introduced as Virtual EC Set Point. It is not possible to assign EC Set Point to an Output between 1 and 6.
-To establish a Relation between some Products that regulate to get the EC Set Point, each output of these
products must be programmed with P. Therefore, it is necessary at least two Outputs configured as P.
-An Output configured as V (Variator for Multifertic on Servos) programmed to work with EC Set Point, allows
only the Servos Outputs (S) to be programmed as P (Proportion), PH, or M (manual), but not as %.
-Only one pH Set Point is possible.
Errors referred to pH Programming:
-Only one pH Set Point is possible.
Errors referred to % Programming (Proportionality)
-When there is a Control Output configured as V, and it is programmed by Proportionality (%), Servos Outputs (S)
must be programmed as % (Proportionality), PH, M (manual) or also a Servo Output as EC, but never as P (Relation
of Proportion).
Errors referred to manual Programming (M)
-When there is a Control Output configured as V, and it is programmed as manual (M), Servo Outputs (S) must be
programmed as M (manual) or PH.
