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.
9.
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.
10.
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.
11.
Dispenses from a slide gate are not as consistent as they should be.
•
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.
12.
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.
13.
At the end of each cycle the MIX MOTOR runs for a fraction of a second only.
•
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.
Mix Problems
Customers with mix problems have several options available.
Decrease the batch size by lowering the FUL parameter value. This does two things. First, it causes the components to be
dispensed in smaller, more frequent batches, which places more and smaller layers of material into the mix chamber. Second, it
lowers the level of material in the mix chamber immediately after a dispense. It is critical to proper mixing that the mix blades reach
up through the top of the material in the mix chamber during mix time. Dispensing a large batch may bury these blades,
