6. INPUTS AND OUTLETS
6.1. INPUTS
The unit has four digital inputs (D1,D2,D3,D4).
Three of them work as switches (D1,D2 and D3),
starting or stopping the corresponding programme,
while the fourth one is a breakdown input (D4).
The activation of inputs is done through their
connection to the common.
A time for the detection delay can be
configured for every input, but the deactivation is
immediate
.
The pH and conductivity reference, as well as
the proportion between fertilisers can be configured
for every input or programme 1, 2 and 3. If more than
one input is activated at the same time, the
programme which has priority is the one with the
lowest cardinal number.
Input 4, breakdown, is only taken into account if
a programme is working.
The unit also has an input for pH sensor
(terminal type BNC) and another one for conductivity
sensor.
