our G2 or MLAN software, then a 3-digit or 5-digit number will be displayed in this field. If a new
recipe number is entered and the TAG or EXIT key is pressed, the controller will display:
Waiting
for Recipe…
At this time, the controller is requesting a recipe from the G2 Software using the
MLAN protocol. A matching recipe number found in the G2 Recipe database will then be sent to
the controller, enabling or disabling components and setting settings. G2 will then begin tracking
material usage for that recipe. If the G2 Software does not have a matching recipe number, the
controller will alarm briefly and then revert back to it’s previous loaded recipe. A successfully
loaded recipe number will be displayed and "tagged" to all printouts and retrievals. EXIT will exit the
sequence at any point. Exit will also abort a pending Recipe Auto Download.
EXIT
- This key is operational in ALL MODES.
Use the EXIT key to exit any and all keypad sequences.
CE
- Press "CE" at any time to display raw data readout of the load cells for five seconds. This is helpful in
diagnosing possible load cell problems and is explained in detail in the MAINTENANCE section.
"CE" is used frequently in connection with other keys, to clear or scan through selections.
KEYPAD - MANUAL MODE
In this mode, you may operate individual functions manually for test purposes. No totals are saved and
automatic operation does not take place. The low level sensor has no control or effect over manual
operation requests.
The Row of keys marked OPER, TIME and CAL operate in this mode coupled with all device keys; REG,
NAT, COL, ADD, DUMP, MIX, HOLD, and ALRM.
You can enter this mode only when the controller is between cycles. The sensor must be covered or the
STOP switch must be in the "STOP
–END OF CYCLE" position. When in this mode, no automatic
dispensing occurs.
To enter this mode, press "*", then enter the correct password number. The password supplied with the unit
is "11111." You may change this to any other 5 digit number, if you wish, as explained later (*45). When in
the MANUAL mode, the letter "M" shows at the left end of display.
The following manual functions are available in the MANUAL mode:
OPERATE
- Press once followed by one of 8 keys: REG, NAT, COL, ADD, DUMP, ALRM, MIX, or HOLD.
The selected output operates until the key is pressed again or another output is selected. Only 1 output will
be active at a time. EXIT will exit the sequence and close all outputs.
TIMED
- Press once followed by one of 4 component keys (
REG, NAT, COL, ADD)
. A time in interrupts is
requested; (TIME ---). Three digits must be entered specifying a dispense time up to 999 interrupts (about
4 seconds maximum.) CE will cancel entry before last digit is entered. Following a full 3-digit time entry,
the specified output is activated for the time requested. After the dispense is weighed, the dump valve
automatically operates to empty the weigh bin. If a printer is on line and the Print flag is ON, then output
information will be printed.
EXIT will exit the sequence.
CALIBRATE -
(RATE) Press once followed by one of the 4 component keys (
REG, NAT, COL, ADD)
.
A dispense will occur for 2 seconds. If the amount dispensed is less then 50 grams, a second dispense will
occur for 20 seconds. Using the resulting weight and time, the processor calculates a proper beginning
point dump rate for the start of production blending. After each dispense is weighed, the weigh bin dump
valve automatically operates to empty the weigh bin. If a printer is on line and the Print flag is ON (see
KEYPAD *54), then output information will be printed. EXIT will exit the sequence.
If the display says (FAILED DO AGAIN), press any key to cause the process to repeat itself. If the display
then says (FAILED NO GOOD), the dispense weight was below 2 grams, not enough for a valid calibration.
During initial operation, after each power up, the blender calibrates itself completely automatically,
regardless of how far off the initial flow rate may be. This may take several cycles. During normal
operation, calibration correction occurs continuously.
Since this unit adjusts flow rates automatically, manual Rate Calibration is not necessary for proper
operation.
