QS200 WIRING INSTALLATION (Tee and Meter should be installed before splice connections)
Make sure wiring is only done on low DC voltage (7.5 V
DC
to 36 V
DC
). Make sure to follow all of the Controller/Decoder
manufacturer’s directions for electrical safety. Also, refer to the
General Safety Instruction
section provided in this
document.
NOTE:
Please read this entire section before any physical wiring installation is started.
During this procedure DO NOT pull on the QS200 wires
under any circumstances.
1. Locate wires on QS200. Red wire (+) and Black
wire (-) are the only two wires on QS200.
2. 1 Pair - #18 AWG wire cable (Direct Burial)
cable is recommended. Controller manufacturer
may recommend thicker gauge wire for longer
distance (which is fine since the recommended
splice kit accepts thicker gauge wire sizes).
3. Document the specific cable wire colors that are
being spliced to the QS200 Red (+) and Black (-)
wires. This will help when connecting the other
end of the cable to the controller (as described in
Step 7 of this section).
4. 3M DBR/Y-6 splice kit (or equivalent) is
recommended to splice connect the QS200
to the cable. Follow instructions (See Below
3M DBR/Y-6 Splice Instructions for QS200) on
splice kit to ensure a good, solid, and waterproof
connection is obtained.
5. Ensure that a service loop is provided at the flow
meter in case future maintenance is needed.
6. Make sure not to puncture or splice the cable
that goes from the meter to the controller/
decoder (to prevent ground interference). Make
sure cable length is within controller/decoder
manufacturer’s recommendation.
7. Connect the (+) and (-) ends (as described in
Step 3 of this section) of the direct burial cable
to the controller’s/decoder’s flow sensor input
(or port) per controller/decoder manufacturer’s
direction. Keep in mind that the flow sensor input
(typical designation for irrigation controller’s
flow meter/flow sensor input) or the port (typical
designation for decoder’s flow meter/flow sensor
input) must be an input that can accept a flow
sensor and provides power to the QS200
(7.5 V
DC
to 36 V
DC
).
3M DBR/Y-6 Splice Instructions for QS200
NOTE:
Wiring diagram is shown in Figure 13.
1. When using cable, cut off the unused wires so
that they are even with the sheath of the cable.
NOTE:
Remember the color of the twisted pair of wires you
use so that you can make an identical connection with the
same wires later.
2. 3M DBR/Y-6 Splice Kit Instructions:
a. Strip insulation ¾ in. (19 mm
(see Fig. 12a).
b. With wire ends even, insert wires
into the connector and tighten
until secure (see Fig. 12b).
c. Insert the connector all the way into the tube
until the connector rests on the bottom of the
tube (see Fig. 12c).
NOTE:
If having difficulty getting the twist-on connector
down into the tube when using small gauge wires, use a
thin, non-conductive object to push the connector to the
bottom of the tube. Upon removal of the object, ensure that
no voids or water paths remain in the grease.
d. Fold the wires into the channels.
e.
Close the cap (see Fig. 12d).
