TYPICAL PROBLEMS

These problems are based on phone calls that we have received from GB/WSB Autoweigh Blender.

The display does not read close to zero when power is turned on, bin empty (plus or minus 10 grams).

*The load cells are not plugged in.

*The weigh bin is not resting properly and freely in its platform or the platform is not resting properly on the bolts that protrude from the load cell enclosures.

*The controller was never calibrated for these load cells or you just did a CLEAR ALL. In this case it will most likely read about 400 grams. See LOAD CELL CALIBRATION.

*The load cells are damaged. See CHECKING THE LOAD CELLS

The Controller "RESETS" itself for no reason. This indicates electrical noise or voltage spikes disrupting the processor.

*See WIRING CONSIDERATIONS, ASSEMBLY section.

The ALARM is flashing and the display shows a weight above 100 or below -50 grams. If above 100, the Weigh bin dump valve keeps opening and closing every 6 or 7 seconds. * There is material in the weigh bin that will not dump out.

*The dump flap may be stuck.

*The load cells are hung up or obstructed.

*The load cells are out of calibration.

*Incorrect grounding is causing wide load cell readouts.

The VERY FIRST DISPENSE

does NOT take place.

After a few seconds the

ALARM begins to flash.

The display says (N

x.x) and is flashing.

*The air supply is not connected or the pressure is set too low.

*The Natural solenoid is not connected properly.

*The 1/2 amp panel front fuse is blown.

*The NATURAL air cylinder is jammed. Maybe the mount is bent.

The NATURAL dispense valve continues to dump repeatedly even though the weigh bin has filled to overflowing. The weight reading is still below 2000.0 grams.

*The weigh bin is not free to move.

*The load cells are jammed.

*The load cells are damaged. See CHECKING THE LOAD CELLS

The system operates but always needs MANY RETRIES to complete a dispense and never seems to "learn" the proper dispense rate.

*The Minimum rate parameter is set to high. To correct, turn power off and then on again. The software will recalculate this parameter within the first 10 or 20 cycles.

The THUMBWHEEL SWITCHES do not seem to be controlling output. One or more LEDs (3 at bottom right) are on all the time.

*Someone has LOCKED IN a setting using the keypad. See KEYPAD, PROGRAM MODE, SETTING.

*The _SE parameter is LIMITING the thumbwheel switch setting. See KEYPAD, PROGRAM MODE, and PARAMETERS, _SE.
