TIMERS
OVERVIEW
The XGC-1 uses 2 timers to control the hydroponic pump functions. It also has a 24-hour time-clock which
controls your daytime and nightime functions.
ADJUSTABLE RECYCLING TIMERS
The two Adjustable Recycling Timers (ART) provide an adjustable “ON” / “OFF” cycle for various devices. The 2-adjustable
recycling timers onboard the XGC are set using the dials on the front face of the enclosure. The timer name and range of each
timer is printed around the timer dials. Because the dials of the XGC are small to conserve space, the settings may have to be
adjusted to an actual time setting. If necessary, use a watch or stopwatch to confirm the settings are correct. Once the timers are
set, they are repeatable to +/- .5%.
The timers are designed to finish the cycle they are presently timing which means adjustments made to the timers during a
cycle will not affect the present cycle.
RESETTING HYDRO TIMERS:
The Hydro timers can be reset by switching the Hydro mode select switch to the center
“OFF” position momentarily. Switching back to your desired mode starts the timing cycle.
HYDROPONIC PUMP TIMERS
The Hydroponic outlet can be configured to cycle one of two ways… 24-hours a day or, during the “daytime” only. Simply
moving the Hydro Mode selector switch to either the “24-Hour” or the “Daytime” position enables the desired mode. When
used in the Daytime” mode, the Hydro outlet will only cycle while the lights are on. The “24-hour” mode works great for NFT
or aeroponic systems that require moisture during the day and night. The mode selector switch also doubles as a Hydro bypass
switch. Each time the switch position is changed, the hydro timers will reset and initiate a new cycle. This comes in handy
during set-up of the hydro pumps and timer settings.
There are two timers that control the hydroponics receptacle, Hydro “ON” and Hydro “OFF”. The XGC-1’s Hydro “ON” time
can be set from 30 seconds to 20 minutes; the Hydro “OFF” time can be set from 12 to 480 minutes. Set the timers by moving
the dial to the appropriate position.
24 HOUR, TIMECLOCK
The timeclock selected to run the XGC performs all of the day to night transitions required for crops requiring controlled
photoperiods. It can directly control up to 1000 watts of HID lights.
To set the current time on the timeclock, turn the dial clockwise until the current time on the outer dial lines up with the arrow
on the inner dial. To set the timeclock on and off times, carefully push in each of the orange trip levers at the times you want
the lights to be on.
*NOTE: If power is interrupted, the timeclock may have to be reset.
