R & M Int'l CGC-1e warranty Troubleshooting, Making Connections

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.

The fuse continues to blow.

My CO2 outlet never comes on.

The fans are running so often, the CO2 is hardly ever ON.

My CO2 consumption seems to be quite high.

The CO2 level “overshoots” the PPM- 1c set point considerably.

The Hydro pumps are not cycling properly.

Check the fuse and main power. Replace the fuse if required with the correct rated fuse.

Check the equipment connected to the CGC-1e for problems and/or short circuits.

If the fuse blows repeatedly, verify the devices connected to the unit are working properly and that they are not too large for the CGC-1e to safely control.

You may need to consider using expansion modules, (UPM / HPR / MLC) to decrease the amperage (load) on the CGC-1e fuse.

Verify the PPM-1c jumper or the PPM-1c is connected.

If the Exhaust outlet is ON, the CO2 will not be allowed to run. Turn up the Temperature and Humidity to a higher setting.

In order for the CO2 outlet to function, the timeclock must be in “Daytime” mode. The CO2 is only activated when the lights are “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 CO2 is allowed to run for longer amounts of time.

Make sure your area is sealed. You may want to install a motorized damper to seal your exhaust fans when they are “OFF”. Even though the CGC-1e operates a standard “timed-release” sequence, you may still be “wasting” CO2.

If you are operating compressed CO2 valves, consider purchasing the optional PPM-1c “Part-Per-Million” sensor to upgrade to PPM control. The PPM-1c offers a significant improvement in CO2 efficiency.

Small areas need less “Inject Duration” time than do larger areas. Larger areas need more “Inject

Frequency” time in order to give the CO2 time to “mix” properly with the ambient air and measured by the PPM sensor.

Start with lower CO2 timer settings for small areas and increase the timer settings for larger ones.

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”.

MAKING CONNECTIONS

All of the main functions controlled by the CGC-1e 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 CGC-1e must be less than 15-amps @ 120 VAC.
