MAX Weight Alarm
Press (*,7,4) to set a flag that will cause the system to stop and the Alarm to activate when MAX weight is
exceeded. This might occur if a valve sticks open or slightly open. Normally the system recovers
automatically from such events with only the one batch blended incorrectly. Set the flag only if you want
the system to stop and alarm.
Press * key to toggle between (MAX OK ) and (MAX ALARM).
Press EXIT when done.
Weight Reading Alarm
Press (*,7,5) to set a flag to ALARM if the weigh bin weight drops more them 20 grams during a cycle.
This serves to detect and report a weigh bin problem, such as material leaking from the bottom of the bin.
Parameter Printout
Press (*,7,7) to print a copy of all internal parameters. A printer must be connected and ready. Up to 13
lists will print, a General list and 12 component lists. Only components that are turned "on" will print. Four
columns will print, RAM; ROM; 200 and 900 series tables; and EEPROM. Identifying headings print above
each column.
Change Program Mode Password
Press (*,7,8, followed by a 5 digit number) to change the PASSWORD number for entering the
PROGRAM mode. The system is supplied with the number "22222" as the password number. If you wish
to restrict use of this mode to only yourself, you may make up your own number and enter it here.
If you forget your password number, call us. We can help.
Precision Ratioing - Additives
Press (*,8,2) to produce a precision ratioing of a selected Additive. Press CE to toggle between (P/R
OFF), (P/R 1), (P/R 2), etc. Only those components already designated as an ADDITIVE will be
displayed. If precision rationing is selected, the specified additive (selected by the *82 function) will
dispense BEFORE the Naturals, instead of after. Natural dispenses occur after the selected additive
dispense and are calculated to assure the most exact percentage ratio for the selected component.
Because the Natural dispenses are larger, this method allows for more exact ratioing of the one selected
critical component.
Volumetric Mode
Press (*,8,7) to set flag for operation in a VOLUMETRIC mode. Use the * key to toggle the flag ON or
OFF. Press EXIT when done. When power is turned off this flag is always reset to OFF. With this flag
ON (VOLUMETRIC mode), the load cells are completely ignored. Error correction and rate recalibration
does not take place. The unit functions like a volumetric feeder without checking or correcting for errors.
Since load cell readings are ignored, this flag allows operation even if the load cells become damaged.
Dispense times will be based entirely on the WT and TI parameters.
Printout Display
Press (*,8,8) to force a printout of the display on the controller front. DATE, TIME, Machine number, and
display will print:
Date:
11/09/93
Time:
17:22:01
Machine number: 002
Display Readout:
P 500.0
This is useful for obtaining printed verification of load cell accuracy ISO and other international quality
program rules.
The recommended procedure is:
1. Place the unit into the Program mode.
2. Press *88 for printout of empty bin TARE weight.
3. Place a KNOWN CERTIFIED WEIGHT into the weight bin.
4. Press *88 again for printout with the weight added.
5. The different between the two weight printouts should equal the KNOWN CERTIFIED WEIGHT.
