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.

*The dispense valve is sticking, slightly delaying it's opening.

The time period is too short for the valve to begin moving.

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.

After a "CLEAR ALL", LOAD CELL CALIBRATION is necessary.

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. *

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.

The Weigh Bin dump valve does not stay open long enough for the bin to empty fully.

*The air flow control valve is adjusted too far in and the valve opens too slowly. This should be adjusted to slow the closing just enough to prevent excessive banging.

*The DTI parameter is not set for enough dump time. This parameter controls Dump Time (DTI). Recommended times are 2000 grams = 6 sec.; 4000 grams = 10 sec.; 9000 grams = 4 sec. Entries are in seconds. See PARAMETERS for more information.

The MIX MOTOR runs when set to ON but not when set to TIMED.

*The fuse on the RELAY circuit board is blown. See hardware maintenance for replacement instructions.
