FEEDER POWER OUTPUTS (receptacles on panel front)
Each outlet puts out 120 volts (240 outside USA) through internal plug-in solid-state relays
rated and fused at 3 amps. These relay outputs are designed to drive motors or other devices
requiring power up to 3 amps each. The LEFT outlet is for component number 5, and the
RIGHT outlet is for component number 6.
Do Not use these outlets to power other
devices.
Fuse for Feeders - 3 amp
Fuses power to the circuit board power supply, which includes all solenoid outputs
and solid-state relay outputs.
MIXER MOTOR OUTLET
This outlet is energized continuously when the MIXER SWITCH is ON (up). In the TIMED
position, it stays energized for a time period following the dump of the weigh bin. You may
adjust this time in the parameter table (MIX 03015). This time should be just long enough to
provide adequate mixing. Mixing for a longer period may contribute to a static problem. Also,
excessive mixing sometimes causes separation of pellets of different size and weight.
MIXER MOTOR FUSE - 3 amp
Located above the Mixer Motor outlet, this fuse is rated at 3 amps and protects the mixer motor
circuit separately from all other fuses. On 100, 200, and 400 series models, this fuse protects
the mix motor directly. On 900 and 1800 series models, this circuit operates a 25 amp solid-
state relay in a separate box. The mix motor is protected by a "motor starter" switch with a
"heater". This switch must be on for the motor to operate.
LEVEL SENSOR input
The high level sensor in the mixing chamber plugs into this outlet and signals the controller to
start a dispense cycle when it is uncovered. The sensor must be uncovered for at least 2
seconds before a cycle will start (see DLY 00488 Parameter). Once a dispense cycle is
started, covering the sensor does not stop it. Operation continues until the cycle is complete.
INTERNAL FUSES
An in-line fuse is provided internally to protect the main 120-volt power cord supply (10) amps. If this fuses blow, an internal
short circuit is indicated and we don't recommend that you try to fix it. Remember, this unit carries a five-year warranty; just
send it back.
The MIX MOTOR timed power source and the AUGER FEEDER OUTLETS are driven by internal solid-state plug-in relays.
These relays are located on the circuit board mounted on the inside back surface of the controller enclosure. A small 5-amp
glass fuse is located to the right of each relay. A spare fuse is also located on the board if replacement is necessary.
