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.
