The receiver can provide its output in any one of
four different formats. The format chosen depends
on the controller to which the receiver is attached.
The receiver outputs signals on two channels,
channel A and channel B. A set of six (6) jumpers
(three for each channel), are used to set the
receiver output format. A description of each output
format is shown as follows:

In this output configuration the receiver outputs a
5-Volt logic signal regardless of the input supply
voltage to the receiver. The output signals are
shown in Figure 6.

Mount the transmitter to the meter as follows:
1. Inspect the top of the meter and the holes for
the pickups. The top meter surface and pickup
receptacles in the top of the meter must be free of
dirt and debris that would interfere with mounting of
the transmitter or increase the distance between
the pickups and the gears. Clean both of these
areas as required.
2. Inspect the pickups on the transmitter. The
pickup tips are magnetic and will tend to attract
magnetic debris. Any debris that has a t t a c h e d
itself to the pickups must be removed before the
transmitter is mounted on the meter. A small stiff
brush is useful for removing this debris.
3. Remove the three (3) screws that secure the
transmitter cover and remove the cover.
4. Place the transmitter on top of the meter with
the fiber connector oriented towards the fluid
inlet on the meter.
5. Install a #8-32 x 1” socket head cap screw
in each of the transmitter mounting holes. Tighten
these evenly until they are snug.
6. Install the transmitter cover in the reverse
order that it was removed.
