TROUBLESHOOTING
If you are having problems with this unit, refer to these troubleshooting hints. Also, refer to the connection diagram
to ensure your devices are connected properly.
Problem Suggested Action
♦ I have no lights and no
function at all. ♦ Check the fuse and main power. Replace the fuse if required with the correct rated fuse.
♦ Check the equipment connected to the XGC for problems and/or short circuits.
♦ The fuse continues to
blow. ♦ If the fuse blows repeatedly, verify the devices connected to the unit are working properly and that they
are not too large for the XGC-1 to safely control.
♦ You may need to consider using expansion modules, (UPM / HPR / MLC) to decrease the amperage
(load) on the XGC fuse.
♦ The fans are running so
often, the CO
2
is hardly
ever ON.
♦ You may have too much heat building up in your area or too small of an exhaust fan. Reduce the heat
sources or increase your fan size.
♦ You may also consider using a “closed-loop” air conditioner to keep the temperature and humidity
below the set points so that CO
2
is allowed to run for longer amounts of time.
♦ My CO
2
consumption
seems to be quite high.
♦ Make sure your area is sealed. You may want to install a motorized damper to seal your exhaust fans
when they are “OFF”.
♦ The Hydro pumps are
not cycling properly. ♦ The Hydro pump outlets can be operated 24-hours a day or only when the “Lights” are “ON”. The
“Hydro” selector switch also has a center “OFF” position, which can be used to “reset” the timing
function. Make sure the switch is not turned “OFF”.
♦ The CO
2
outlet is pulsing
ON and OFF too often.
♦ If you are running a CO
2
generator, you may want to change to ON / OFF control.
♦ If running compressed CO
2
you may want to try running an Auto tune.
♦ After my compressed
bottle or LP tank was
replaced, the level
fluctuates. ♦ If your CO
2
tank runs out for a period of time, the controller may take anywhere from a few hours to a
couple of days to re-stabilize, this is normal. When the tank ran out, the PPM-2a tried to compensate by
changing its internal settings.
♦ My CO
2
outlet never
comes on.
♦ Make sure the CO
2
disable function is not ON.
♦ If the actual CO
2
level is above the set point (SV) the outlet will not turn on. Allow the level to drop or
raise the (SV).
MAKING CONNECTIONS
All of the main functions controlled by the XGC are accessed using (8) standard 120 VAC, 15-amp receptacles mounted on
the sides of the enclosure. This allows you to simply “plug in” any standard device without hardwiring or hassles. Printed
labels on the front face of the enclosure identify the receptacles.
We highly recommend using only 3-wire devices with a ground. Suitably double-insulated devices are acceptable. Keep in
mind that the combined amperage draw on all of the devices connected to the XGC-1 must be less than 15-amps @ 120 VAC.
