ControlWave Gas Flow Computer (GFC Plus) Instruction Manual (CI-ControlWave GFC Plus)
1-6 Introduction Revised Feb-2013
 Internally mounted factory-supplied 12V, 33AH lead acid battery
(UL approved)
 Externally mounted user supplied power (12Vdc bulk or regulated
power)
 Externally mounted +12Vdc battery with lithium backup battery
If you connect solar panels to rechargeable battery systems to power the
ControlWave GFC Plus, there is a secondary power input you can use to
provide power if there is no power from the solar panel/battery system.
Note: If you use an external power source to provide bulk power, you
require the power distribution board. This board mounts to the
inside of the enclosure using a Snap Track secured to the dual
PCB mounting bracket.
1.5 I/O Options
ControlWave GFC Plus comes with the following standard I/O:
 2 Pulse Counter Inputs with a 1 second scan rate (can be configured
as discrete inputs (DI))
Optional I/O includes:
 Resistance Temperature Device (RTD) probe
 Either a Multi-Variable Transducer (MVT) or Gage Pressure
Transducer (GPT)
 Process I/O board. Three different versions of the optional process
I/O board are available. See Table 1-2.
