SILENCE ALARM
This button stops the STROBE and BEEPER ALARMS, but does not remedy the cause of the
alarm.
The continuation of the cycle to its proper completion will also stop
the alarm. When in the BATCH mode, this button also serves to
start the next batch.
ALARM SPEAKER
MIXER MOTOR ON/OFF/TIMED SWITCH (optional)
The Mixer ON/OFF/TIMED switch is provided as an additional safety so that you may switch the
mixer off when you wish to clean out the mix chamber. In the UP position (ON), the mixer runs
continuously. In the middle position (OFF) the mixer is off. In the down position, the mixer will
run for a timed period following the dump of the weigh bin. The TIMED position is generally the
correct choice.
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.
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.
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.
