The regeneration signal will be sent as soon as the lockout
signal is terminated. A lighted decimal point at the lower right
corner of the display will indicate the presence of a lockout
signal. (An open collector/switch contact or a 115 VAC signal
can be used as the lockout signal.) When using a 115VAC
lockout signal, the lockout logic can be reversed. (See settings
for Switch 2 in section below.) If the 115VAC lockout signal is
not used, Switch 2 must be in the off position. The lockout
signal will be ignored if the output is energized.
SELECTING THE MODE OF OPERATION
Select the mode of operation and maximum batch size re-
quired for your particular system. (For location of switches,

Switches 3 & 4: (See chart) Set switches for the maximum
batch size for your particular size of meter.
Example:
You have a 2" Industrial Turbo meter and your batch
size is 500000 gallons, set switch 3 to the off position, and set
switch 4 to the off position. (This will allow you to set a maximum
batch size of 999000 gallons.) Attach the X1000 sticker to the
front panel.

OPERATION
The basic function of the AR/e controller
is to provide a signal to external equip-
ment once a predetermined amount of
water has been measured by the water
meter. The batch is preset and the dis-
play counts down to zero. At this point
the output relay is energized for a pro-
grammed period of time providing the necessary signal for
manual or automatic regeneration.
The controller is designed to function with a minimum of
operator control after the initial setup procedures. All displays
and controls are located on the front panel for fast, accurate
and convenient operation.
GENERAL PROGRAMMING PROCEDURE
In addition to the LED display and the digit keys, the front
panel of the AR/e controller has two command keys (START
and STOP) and three program keys (PRESET, SIGNAL DURA-
TION and UP-DOWN COUNT).
To prevent tampering or accidental mistakes, the keys must be
depressed twice in succession for the command to be recog-
nized and acted upon.
If the second command is not received
within ten seconds of the first, the unit will revert back to its
previous operation.
PROGRAMMING SEQUENCE
To interrogate the present value
of a programmable function,
depress the appropriate function key. The display will show
the function symbol and the present value of the function
alternately for ten seconds and then revert back to normal
operation.
To preset a new value
, press the appropriate key and change
the value by using the "
digits
" keys. Pressing a digit key
continuously will cause the number to scroll. When the desired
number is reached, remove your finger from the digit key.
Change one digit at a time, within ten seconds of each other.
After the new value is displayed, press the key again, to store
it in memory.
The unit will not react to any new values until it counts down
to zero. To accept the new values immediately, "zero" the unit
using the UP/DOWN key.
