Connecting the DC Power Source
WARNING: Verify that the power source is unplugged or turned off at the power source
end before you continue with this procedure.
Perform the following procedure to connect the DC power source to the Pioneer.
NOTE:
A jumper block located at the middle upper edge of the main circuit board
allows you to configure the Pioneer to operate from either 12 VDC
or
24 VDC.
To select 12 VDC operation
(input range of 11 to 22 VDC), install the jumper
block over the right two pins.
To select 24 VDC operation
(input range of 23 to
60 VDC), install the jumper block over the left two pins. The factory default
configuration is for 24 VDC operation.
1.
Open the housing door, and locate the bottom external wiring terminal strip (TB2).
See Figure 2-1, Pioneer Gas Monitor Component Location, to assist you in locating the
bottom external wiring terminal strip.
2.
Guide a DC power cord through one of the conduit hubs on the bottom of the Pioneer
housing.
CAUTION:
