Typical Problems
These problems are based on phone calls that we have received from Weigh Scale Blender users.
1.
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 be off by several hundred grams. See LOAD CELL
CALIBRATION.
•
The load cells are damaged. See CHECKING THE LOAD CELLS
2.
The Controller "RESETS" itself for no reason. This indicates electrical noise or
voltage spikes disrupting the processor.
•
See WIRING CONSIDERATIONS, ASSEMBLY section.
3.
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.
4.
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 slide gate is jammed. The cylinder mount may be bent.
5.
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
6.
The system operates but always needs MANY RETRIES to complete a dispense and
never seems to "learn" the proper dispense rate.
•
Vibration is causing frequent "bailouts" causing large swings in rate adjustment.
Increase the BER parameter.
