The _SE parameter is LIMITING the thumbwheel switch setting. See KEYPAD, PROGRAM
MODE, and PARAMETERS, _SE.
Occasionally, the system gets STUCK doing retries of a component but the retry time is so

short that nothing gets dispensed.
•
The LAG TIME parameter is set for too short a time. See KEYPAD, TIME, and PARAMETER,
_LA.
•
A valve is sticking closed. Check for free operation when air pressure is removed.
The system USED TO WORK but now it does unexplainable things.

•
Static or a voltage surge has altered RAM memory. Do a CLEAR or CLEAR ALL. See
"CLEAR" RESTART or "CLEAR ALL" RESTART. Then do a LOAD CELL CALIBRATION, and
RATE CALIBRATION for ALL materials.
The Display reads 3100.0 even with the bin empty. This is the upper limit load cell readout.

•
The Load Cells are not plugged in and the circuitry has drifted to the top limit.
•
The Load Cells have been overloaded way beyond their limit and are now permanently
deflected.
Dispenses from a slide gate are not as consistent as they should be.
11.
•
The slide gate is sticking slightly. With the hopper empty, move the slide manually to see that it
moves freely. Press up or down on the air cylinder to adjust for proper alignment.
•
The material does not flow very well. A bridge breaker adaptor may be required.
Load Cell weight readings are not holding steady. They vary as much as 100 grams from

second to second.
•
This is static and improper grounding. See WIRING CONSIDERATIONS
•
If readings drift slowly in one direction, requiring frequent recalibration, a component on the
circuit board is most likely faulty. Call us.
•
If TARE weights are not steady, something may be physically interfering with free movement of
the cells.
At the end of each cycle the MIX MOTOR runs for a fraction of a second only.
13.
•
The MIX MOTOR pulls a heavy amp load on start up. If the power supply is not adequate (like
when using an extension cord), the voltage will drop so low that the computer will reset and the
mix motor signal will shut off. The display will show this by restarting as if power was just turned
on. Provide a better supply of power; remove extension cord or use larger gage wire.
