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.
SPECIAL TESTS
Using the *54 flag
If you are running these 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 or CALIBRATE.
TIME (See KEYPAD, TIME; and PARAMETERS, _LA, for more information)
The TIME function is to determine lag times of different metering
devices. It also allows testing of device repeatability.
The single line printout looks like this:
TIME COMP 1 123 2749
key: ^component number
^dispense time (in interrupts; 244 = 1 sec.)
^weight dispensed
CALIBRATE (See KEYPAD, 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 single line printout looks like this:
CALIBRATE COMP 1 732 8795 15 3465
key: ^component number
^dispense time
^weight dispensed
^lag time used
^min rate
