EQUIPMENT INSTALLATION CONTINUED
Electrical Connection
CAUTION This valve and control are for dry location use only
unless used with a Listed Class 2 power supply
suitable for outdoor use.
All 700 Series controllers operate on 12-volt alternating
current power supply. This requires use of the supplied AC
adapter. A variety of AC adapters are available for different
applications. These AC adapters are available from your
supplier. They include:

Lists Section
100 VAC, 120 VAC and 230 VAC AC Adapters
Make sure power source matches the rating printed on the
AC adapter.
NOTE:
The power source should be constant. Be certain
the AC adapter is not on a switched outlet. Power
interruptions longer than 8 hours may cause the
controller to lose the time and day settings. When
power is restored, the day and time settings must
then be re-entered.
The 700 Series controller is available in two power
configurations. The North American controller operates on
60 Hz. If the incoming power is 50 Hz, the "North American"
controller will not function. The error code "ERR 2" will show
on the display.
The "World" controller will sense the input power as 50 or 60
Hz and operate accordingly.
Controller Location
The 700 Series controllers are designed to be mounted on
the valve or attached to a flat surface. Installations that do
not provide easy access to the valve can have the controller
mounted for remote operation.
A remote mount connection, P/N 1256257, is available for the
700 Series controller.
Valve Camshaft
The front end of the camshaft has an indicator cup. The cup
has slots in the outer periphery and numbers on the inside
face (Figure 13).
The numbers can be seen with the cover off, from the front
over the top of the controller. The number at the top indicates
which regeneration cycle is currently in progress.

The corresponding slot for the number is positioned at the
optical sensor which is approximately 90 degrees out of phase.
