3.Third, look at the dispense TIME (DATA line 3).
Very short times (10, 20, 30 interrupts) indicate dispense devices not well matched to the task. Accuracy on a percentage basis, cycle to cycle, will suffer. This may very well be acceptable as long as overall usage percentages are still accurate.
BAILOUT: (line 4)
If bailouts occur, vibration is usually the cause and these bailouts may be causing other problems. Raise the value of the BAL parameter to 200 or 300 grams to reduce or eliminate unnecessary bailouts.
Vibration may also cause throughput rates to suffer due to the added time requiring to obtain acceptable weight readings. Increase the WDF parameter to 2 or 3 grams, (WDF 00003) or (WDF 00030), or more if necessary.
The last number in the last line is the CYCLE count, a convenient way to keep pages of data in order, like page numbers.
SPECIAL TESTS
Using the *54 flag
If you are running special tests in the MANUAL or PROGRAM mode, a printout will automatically occur after each test provided the PRINT flag (*54) is turned on.
Special tests that produce printouts are TIME and CALIBRATE.
TIME | (See KEYPAD, MANUAL MODE, TIME for more information) |
The TIME function is to determine lag times of different metering devices. It also allows testing of device repeatability.
The printout looks like this:
TIME | NATURAL | 123 | 274.9 |
|
| ^dispense time (in interrupts; 244 = 1 sec.) | |
|
|
| ^weight dispensed |
CALIBRATE | (See KEYPAD, MANUAL MODE, CALIBRATE for more information) | ||
The CALIBRATE function allows the controller to rapidly learn the flow rate of the device. It automatically sets the WEIGHT and TIME parameters that determine metering rate, and the MINIMUM RATE parameter. For more information see PARAMETERS, _RA, _TI, and _MI. The printout looks like this:
CALIBRATE NATURAL | 732 | 2079.5 | 15 | 346.5 | |
| ^dispense time |
|
|
| |
|
| ^weight dispensed |
| ||
|
|
| ^lag time | used | |
|
|
|
|
| ^min rate |
