NORMAL OPERATING SEQUENCE

This section tells you how the system is supposed to work. If your system is not operating correctly, this description may help you spot exactly where the system is failing, providing a clue to the problem.

Turn POWER ON:

The following displays occur for 1 second each: Program version date (V=21031A), the check sum number (CKS XXXX), ROM check (ROM OK ), RAM size, (RAM = 8K), Model number

(MODEL220), display of (

0.0), actual

weight in

the bin

is displayed last. It should be close to

0.0, plus

or minus

several grams.

 

 

 

BEGIN operation:

The unit will begin to operate if both switches on the left side are UP in the CONTINUE position and the SENSOR in the mix chamber is UNCOVERED. The sensor must be plugged into the right side of the controller. If it is not, this has the same effect as the sensor being covered; the unit will not run. If the sensor LED (on the sensor) is on, the sensor thinks it is covered. If it is sensing incorrectly, adjust the sensitivity. See ADJUSTMENTS.

If the WEIGH BIN DUMP Flap opens and closes repeatedly:

If initial empty bin TARE weight is 100 grams or more, the weigh bin dump valve will operate in an attempt to empty the bin and bring the starting weight closer to zero. If the bin is empty but the weight reading is greater than 100 grams then something is wrong. See TESTING the LOAD CELLS and LOAD CELL CALIBRATION.

If the ALARM flashes:

If the initial TARE weight is below -50 grams the Alarm will flash and the unit will not operate. go to TESTING of LOAD CELLS and LOAD CELL CALIBRATION.

The DISPENSE sequence begins:

If initial tare weight is within limits, between -50 and +100, the sequence will begin.

DISPLAY during dispenses:

During all dispenses, the letter R, N, C, or A will be displayed indicating which component is being dispensed. The INITIAL display is the tare weight of the bin. This will not change during the dispense. Tree seconds after each dispense, the new total weight of the material in the bin is updated and displayed.

REGRIND first:

If REGRIND has been requested the REGRIND dispense will occur first. The letter "R" will appear in the display. After this dispense an exact weight is taken to determine the space remaining in the weigh bin for the remaining dispenses. The weight of REGRIND dispensed will appear in the display 3 seconds AFTER the dispense has ended.
