700 SERIES CONTROLLER FEATURES
Power Loss Memory Retention
The 700 series of controllers feature battery-free time of
day and day of week retention during loss of power. The
supplied super capacitor is designed to keep time for 8 to 24
hours, depending on the installation. If the super capacitor is
exhausted, the Logix control will display four dashes (--:--)
immediately upon power up. The time of day and day of week
must be reset.
The controller will not track water usage on volumetric
demand controls in the event of a power failure.
All programmed parameters are stored in the 700 Series static
memory and will not be lost in the event of a power failure.
These settings are maintained separately from the time and
day settings.
Motor
The 700 series controller uses a standard 12 volt AC motor
that works with either 50 Hz or 60 Hz. The same motor is
used worldwide and does not need to be changed for different
power conditions.
Power
700 Series controllers are available in two power
configurations:
1. The North American model requires 60 Hz input. The
controller will display USA units when power is first
applied.
2. The World model accepts either 60 or 50 Hz input and will
automatically adjust measurement units when power is
first applied.
Information entered or calculated by the controller is stored in
two different ways.
A static memory will store:
•
Media volume
•
Regenerant setting
•
Time of regeneration
•
Days between regeneration
•
Filter mode
A dynamic memory with eight hour retention will store:
•
Current day of week
•
Running clock
NOTE:
Water flow to the valve can be turned on or bypassed
when the controller is powered up for the first time.
