NOTE: See “Chapter 3: Installation and Start Up” on page 22 for complete Digester Gas
Monitor installation instructions.
CAUTION: Do not adjust the strobe brightness or the horn volume at the horn/strobe, as
this may overload the Digester Gas Monitor strobe control circuit.
Even if the horn/strobe is ordered at the same time as the Digester Gas Monitor, the horn/
strobe does not come factory installed to the Digester Gas Monitor. To install the horn/
strobe:
1.
A 3/4 inch NPT nipple is provided for strobe installation. It is not installed on the horn/
strobe and is in its own bag in the shipping box. Guide the cable coming out of the
horn/strobe through the nipple.
2.
Install the nipple onto the horn/strobe using an appropriate thread sealing method
such as Teflon tape.
3.
If the horn/strobe has been ordered with the Digester Gas Monitor, a conduit hub will
be installed on the top of the housing and will be plugged with a conduit plug. The plug
is included to prevent any debris from falling into the Digester Gas Monitor during
shipment and installation. Remove the conduit plug from the strobe conduit hub.
Continue to step 5.
4.
If the horn/strobe has been ordered for a Digester Gas Monitor that is already
installed, a plug is installed in a hole in the top of the housing. Remove this plug and
install the conduit hub that came with the horn/strobe.
A receptacle with 4 inch wires is included with the horn/strobe. Connect the red wire to
the “+” terminal and connect the black wire to the “-” terminal of the Strobe Terminal
Strip as shown in Figure 9.
5.
Guide the cable coming from the horn/strobe through the conduit hub at the top right
of the Digester Gas Monitor housing.
NOTE: If there is a plug in the conduit hub, remove it before attempting to install the
horn/strobe.
6.
Screw the horn/strobe into the conduit hub at the top right of the Digester Gas Monitor
housing using an appropriate thread sealing method such as Teflon tape. Make sure
the horn/strobe faces forward when installed.
