Invertible polarity latch solenoids vary their performance,
interchanging the order of the cables (consult manufac-
turer). That is to say, they change from normally open
(N.O.) to normally closed (N.C.).
Some manufacturers make specific solenoids for each
operation.
The Filtmaster filter cleaning controller, can work with
different brands of latch solenoids.
JIMTEN recommends a solenoid that, for connections
to normally-open valves, the common is the black cable
while the green cable is the common for connections to
normally-closed valves.
For these solenoids the output common must be the
black cable (check for other models), while for 24Vac and
12 Vdc solenoids the connection polarity is not impor-
tant, although it is recommended to use the same colour
for the output common in order to make future mainte-
nance work easier.
Nous pouvons apprécier qu’il existe une différence de nom-
bre de sorties s’il s’agit d’un programmateur latch.
In this case the internal relay no.1 is responsible for in-
verting the polarity of latch solenoids.
We will connect the solenoids of the backwash valves
according to the following diagram:
There are 4 common terminals (internally bridged).
If there are many cables to be connected to these ter-
minals, we will install an external terminal block for an
appropiate connection to the controller.
If power consumption is higher than 4Amp per output,
resulting from solenoids with greater power consumption
or from the simultaneous connection of a number of so-
lenoids, an external relay should be installed.
As a precautionary measure, mainly for controllers that
make many operations daily, this relay should be insta-
lled to increase the working lifetime.
