If the combustible gas detector is mounted to the junction box, skip to step 5. If not,
continue with step 2.
2.
Remove the junction box cover.
3.
Guide the four wires that extend from the top of the combustible gas detector through
the bottom conduit hub of the junction box.
4.
Screw the combustible gas detector into the bottom conduit hub of the junction box.
5.
At the monitoring site, use 1/4 in.
screws through the junction box’s two mounting
holes to secure the junction box to a vertical surface.
CAUTION:
Mount the combustible gas transmitter with the detector facing down (see Figure 2.)
Wiring the Combustible Gas Transmitter to the Pioneer
WARNING: Always verify that the Pioneer’s power switch is in the OFF position
before you make wiring connections.
1.
Place the Pioneer’s power switch in the OFF position.
2.
Remove the junction box cover.
3.
Verify that the detector leads are wired to the amplifier’s interconnect terminal strip.
If necessary, connect the detector leads to the interconnect terminal strip as shown in
Figure 3.
4.
Guide a three-conductor, shielded cable or three wires in conduit through the top
conduit hub of the junction box.
5.
Connect the three wires to the interconnect terminal strip as follows (see Figure 3.)
•
Connect the positive wire to the terminal labeled
24V +
.
•
Connect the feedback wire to the terminal labeled
4/20 FB
.
•
Connect the negative wire to the terminal labeled
GND
.
CAUTION:
Leave the ground wire insulated and disconnected at the transmitter. You will
connect the opposite end of the cable’s ground wire at the Pioneer.
6.
Secure the junction box cover to the junction box.
7.
Route the cable or wires leading from the combustible gas transmitter through one of
the conduit hubs on the bottom of the Pioneer housing.
CAUTION:
Do not route power and transmitter wiring through the same conduit hub. The
power cable may disrupt the transmission of the transmitter signal to the Pioneer.
