PULSE INPUT (AR/t)
The AR/t transmitter sends pulse signals to the AR/e controller.
Each pulse represents a specific quantity of water for a
particular meter size.

Pulse Rate
RCDL Models 25, 35 and 40
1 pulse = 1 Gallon
RCDL Models 70, 120, 170 and
Industrial Turbo 2", 3" and 4"
1 pulse = 10 Gallons
Industrial Turbo 6"
1 pulse = 100 Gallons
Reed switch transmitters have two black leads. Connect these
leads to terminals 1 & 2 in any order.
Electronic transmitters have one black lead and one white
lead. Connect these leads as per the diagram at right.
In the Automatic mode, the relay will be energized at the end
of the batch for the amount of seconds programmed via the
SIGNAL DURATION procedure (see page 6). The relay con-
tacts can be wired to a timer or regeneration cycle controller.
REMOTE START & STOP (OPTIONAL)
Remote Start Input
When activated, it will abort a batch before its completion,
initiating tank regeneration at the same time.
In the
Manual
mode, the output relay will be energized
indefinitely and the display will be reset to zero until the STOP
command is received.
In the
Automatic
mode, the output relay will be energized for
the programmed duration (see operation section page 6) and
the display will be reset to the batch preset value and continue
to count down when pulses are received.
If a
START
command is received while the LOCKOUT is active,
the command will be stored in memory and acted upon as soon
as the LOCKOUT signal is terminated.
Remote Stop Input
Is used to terminate the output signal. This function is enabled
after a START command is received or after the output relay
is energized at the end of the batch.
In the
Manual
mode, it will terminate the output signal, reset
the counter to the batch preset value and enable the transmit-
ter pulse input.
PULSE INPUT (RTR)
The RTR transmitter/register sends pulse signals to the AR/e
controller. Each pulse represents a specific quantity of water
for a particular meter size.

1 pulse = 100 Gallons
These transmitters have one black lead and one red lead.
Connect these leads as per the diagram.
RELAY OUTPUT
The regeneration signal relay is energized at the end of the
batch or when a START command is initiated.
In the Manual mode, the relay will remain energized until the
SIGNAL STOP is initiated. The relay contacts can be used to
activate a warning device to indicate that manual regenera-
tion of the system is necessary.
In the
Automatic
mode, it will only terminate the output signal.
LOCKOUT INPUT (OPTIONAL)
To avoid simultaneous regeneration of multiple tanks, a lock-
out signal can prevent a controller from sending a regenera-
tion signal at the end of the batch.
