14. 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 03010). 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.
15. MIXER MOTOR ON/OFF/TIMED SWITCH
The ON/OFF switch is provided as a safety so 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 (TIMED), the mixer will run for a
timed period following the dump of the weigh bin.
16. MIXER MOTOR FUSE
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. These larger mix motors are protected by a "motor starter" switch
with a "heater", which must be on for the motor to operate.
17. LOAD CELL input port
The system's two load cells are joined by a common connector that is
plugged into this port.
18. PRINTER output
This is a parallel printer port. A printer plugged in here allows four
types of information to be ported directly to a printer giving the
benefit of a permanent printed record. They are:
1. The totals of the material usage data.
(press VIEW and "*" keys to print once; or use the PRT parameter
to AUTOMATICALLY and periodically print these totals)
2. A listing of the internal parameter table.
(press *77 in the PROGRAM mode.)
3. A printout of information after each cycle including actual
dispensed weights and percentages for every cycle.
(press *54 in the PROGRAM mode, use "*" to set printer flag ON.)
4. A printout of information after the TIME or CALIBRATE routines.
Any common parallel printer that you would use with a small PC computer
may be used. Connect using a standard parallel printer connecting
cable, (34 pin parallel centronix connector to a DB25 IBM compatible
connector), available from us or at any computer store. There is a
detailed explanation of this printout in the PRINTED OUTPUTS section of
this manual.
