The feed adjustment controls the length of time the feeder will run from a split second to approximately 70 seconds after power is initially applied to the jack or the terminal strip underneath the feeder.  Typically, 60 seconds of time will dispense about 1 cup of cat food.  The smaller the food, the more food will be dispensed for a given time.  Power is normally applied to the feeder through its supplied low voltage power adapter, which can be plugged into just about any type of programmable timer such as a common lamp timer, digital lamp or appliance timer, power module with a home automation system (see http://www.smarthome.com ), a clapper switch, a remote control device, etc...  It can also be directly powered by any type of timing device that has a 9 to 24 volt AC or DC output, such as a "Malibu" light timer/transformer (12Vac), a sprinkler timer with 24Vac output, or any other programmable timing device of your own. If wanting to only feed a group of days and skip days, you will need a 7 day (weekly) digital timer.

Normally the reset jumper is set for a standard reset "off" time of approximately 30-60 minutes (could sometimes be a bit longer).  This is the required time that the feeder must be off between feed cycles to reset its internal feed timer clock.  However, you can pull out and switch the little black "jumper" block one notch over to the left using a pair of tweezers or fine nose pliers (make sure not to drop it inside the unit), and you can then reset the feeder's internal timer with only 1 to 2 minutes of "off" time, meaning that you could feed once each 2-3 minute interval using a digital timer with 1 minute available increments.  The standard "off" reset time is useful primarily if keeping the remote timer on for a long time, like with a light.  If doing that, you would not want the feeder to repeatedly trigger and feed several times during a storm (example) with power interruptions while the timer is on.  NOTE!  YOU DO NOT NEED  TO RESET ANYTHING ON THE FEEDER  DURING POWER INTERRUPTIONS/OUTAGES!   NORMAL FEED CYCLES WILL RESUME WHEN POWER IS RESTORED.  YOU SHOULD PROGRAM SEVERAL DAILY FEED CYCLES.  IF USING AN ANALOG TIMER, FEED TIME MAY BE OFF SCHEDULE DURING A POWER OUTAGE, BUT FEED CYCLES WILL RESUME WHEN POWER IS RESTORED.  IF USING A DIGITAL TIMER, BATTERY  BACKUP WILL KEEP EXACT TIME AND FEED PROGRAMS, AND FEED CYCLES WILL RESUME WHEN POWER IS RESTORED.  WE HAVE A PRIMARY BATTERY  SYSTEM, BUT WE HAVE FOUND REGULAR POWER TO BE MORE DEPENDABLE THAN USING BATTERIES WHEN REGULAR POWER IS AVAILABLE.

The reset switch basically serves two functions:  It can void the reset "off" time required between cycles while the power is off to test the remote timer with multiple cycles in a row), and to adjust the amount of food dispensed by pushing the reset button and adjusting the feed dial until you get the amount of food you want dispensed per cycle.   You normally do this before you install your feeder and while you have the supplied power adapter plugged into a 120 volt socket and the feeder is connected to the low voltage power adapter.

The status light is mounted internally for waterproofing.  It illuminates through the plastic and lets you know when the feeder is being powered and also serves as a power status/testing device.  IT WILL NOT BE ON, UNLESS THE REMOTE TIMER IS ON.

The picture above at the right side shows the "volume" adjustment screw which controls the aperture (opening) between the flexible gate and the roller.  It should be adjusted so the gap between the roller and the gate is about or slightly less than the thickest part of the food you are using (not length), so it does not drop through.

The jack fits just about any type of 2.1 mm plug with center positive if using a DC power pack, or the polarity does not matter if using an AC power pack.  Of course each feeder is supplied with its own power pack for you to use, or you could use your own.

The rubber plugs assure weatherproofing, particularly for outdoors use. Be sure to check plugs periodically to make sure animals have not pulled them out allowing water (outdoors) to get inside unit.

The terminal strip does the same thing as the plug and jack.  It can be used for a "bare" wire input hook-up for the KSF-2 Koi-Pond model or the CSF-3 cat feeder to keep animals from unplugging the jack plug, or you can also use it as an output to wire multiple feeders together and trigger them simultaneously (attach second feeder's adapter cord bare wire end to the first feeder's terminals underneath the feeder, and plug the plug end of the cord into the second feeder).  There is a wire clamp to hold the wires in place.  Turn the loop of the clamp so it faces the terminal screws and holds the wire in place.
