The Logix series controllers are set-up to automatically calculate
the capacity of the system by multiplying the resin/media volume
that was entered earlier into the controller, with the regenerant
amount entered by the dealer/installer. This eliminates the need
for salting efficiency tables.
The default setting is "S" (Standard salt)
To enable the most simple programming possible on the 740
controllers, the dealer/installer has three salt amount options to
choose from. These are set up to give the installation the maxi-
mum performance based on the inputs by the dealer/installer.
The three salting options are :
High salt
Standard salt This is the default setting for the controller. This
Low salt
This setting gives the installation the highest
capacity possible for that resin volume. This is a
great setting for applications with very high
hardness, many occupants or for applications
where the dealer wants to always ensure that the
application has soft water. This setting may tend
to use less water over the course of a year, because
it generally needs to be regenerated less often.
This setting is displayed as an "H".
setting fits most applications around the word. It
gives you an efficient use of salt, while maintaining
a large enough capacity to regenerate every three
days for most applications.
This setting is displayed as an "S".
This setting is provided to give your installation
the maximum efficiency of salt usage, as measured
in grains of hardness softened per pound of salt
used (grams of CaCO
removed per kilogram of
3
salt used). This setting is useful for markets where
highy efficient conditioners are expected or required
by the consumers or law.
This setting is displayed as an "L".
