Conair GB, WSB manual Special Tests, Time Comp, Calibrate Comp

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
