ControlWave Gas Flow Computer (GFC Plus) Instruction Manual (CI-ControlWave GFC Plus)
Revised Feb-2013 Installation 2-21
Terminal Block
Connector TB2
The ControlWave GFC Plus includes an alternative power connecter,
TB2, to provide power if none is available at TB1. For example, you
can connect a bulk DC power supply to TB2 to handle situations where
the solar panel/battery system does not have sufficient power.
TB2 connections are:
TB2-1 = Power Input
TB2-2 = Ground (GND)
2.4 Mounting the Solar Panel
Depending upon the type of power system you choose, your
ControlWave GFC Plus may require a solar panel. The solar panel
charges a rechargeable lead acid battery. Solar panel wires enter the unit
through a liquid tight conduit fitting and connect to TB1 on the
CPU/System Controller board.
Caution
If your ControlWave GFC Plus is configured to use a solar panel to
charge a rechargeable battery for power, NEVER CONNECT THE SOLAR
PANEL/CHARGER WITHOUT ALSO CONNECTING THE BATTERY.
Connections without the battery present can damage power supply
components.
You can mount the solar panel to a 2” to 2-3/8” pipe using muffler
(pipe) clamps. You secure the pipe clamps using four ¼-20 nuts and
washers. (See Figure 2-10.)
You must swivel the solar panel for optimum alignment with the sun. In
the northern hemisphere, face the panel due south (not magnetic south).
In the southern hemisphere, face the panel due north (not magnetic
north).
Solar panel systems have adjustable tilt angles. Adjust the tilt angle for
maximum performance to accommodate the latitude of your installation
site. Table 2-5 shows the angle (from horizontal) at which you should
install the solar panel to maximize annual energy output. At most
latitudes, performance can be improved by less of an angle during the
summer and more of an angle during winter.
