6.11 – Connections
The drawing shown on the attached page
A
shows the general connections of the controller, also available on a sticker
positioned under the cover giving access to the terminal board.
The drawings shown on the attached pages

and
C
, show the connections between the controller and, respectively, one
single distributor and one duplex distributor.

With reference to the attached page
A
, two types of litre counter may be used,
the SIATA magnetic sensor with Hall
effect,
and the
Reed counter
, or otherwise a counter which however supplies a simple
closure
between two wires.
In the first case, using the cables
SIATA turbine sensor
, the following connections must be made:

In the case of a duplex system, the magnetic sensor is the same for both of the columns.
The connections shown in the table must be respected rigorously, to avoid damaging the sensor.
In the second case, there are only two wires between which there is a closure for each impulse. These wires must be
connected to the terminals 27 and 28.
The connections of this type of counter are not polarised. They may be assembled in any way.
6.12 – Management of the inhibit signal. Flag 0dL.
In the previous paragraphs, it has been shown that each operative modality has its own type of control on the work
parameters to activate the regeneration cycle. The start of the cycle may be blocked via an inhibit signal to be applied
on terminals
7
and
21
of the controller. When these are closed between them, the start of the cycle is blocked until the
signal stops being applied.
This situation effects the functioning cycle of the controller in a different way depending on the operative modality
being used at the time.
Suppose that the controller is programmed in the
Volume
mode. In the paragraphs 6.2.2 and 6.2.5 it has been shown
that as soon as the volume has run out, the cycle starts immediately. If when the volume runs out there is the inhibit
signal, the cycle will not start; as soon as the signal disappears, the cycle will start.
Suppose now to be in any operative modality which allows for the start of the cycle when the interval
Time
between
two regenerations runs out.
The regeneration will start when the local time is equal to the programmed time for the start of the cycle and the interval
days have passed, or on an active day, or otherwise there will be the deferred start by finished volume in which case the
interval days are not checked.
