11-7. Over Scale Display
EXC. ERR
EXC.ERR turns on when the sensing voltage from the loadcell is too low. Check if the
wiring/connection to the sensor is correct.
LOAD
Signal input to F805AT-BC exceeds the span calibration range. Check if the load cell
output is greater than the allowable span calibration range, or there is any break/
damage in the wires connecting F805AT-BC and the load cell. Note also, that this error
may appear when no device is connected to the load cell connector on the rear panel.
-LOAD
The load cell output has negative voltage. Check if the load is applied to the load cell in
normal direction, or the connections (+SIG, -SIG) is reversed.
OFL1
This alarm comes on when the belt speed exceeds the value set to BELT SPEED
OVER. Slow down the belt speed until this over-scale alarm goes out, or modify BELT
SPEED OVER setting. Also, make sure that settings controlling speed entry are all
correct.
OFL2
This alarm comes on when actual weight density exceeds the value set to WEIGHT
DENSITY OVER. Reduce the signal magnitude from the load cell until this over-scale
alarm goes out, or modify the setting of WEIGHT DENSITY OVER.
OFL3
This alarm comes on when actual feed rate exceeds the value set to FEED RATE
OVER. Reduce the magnitude of load cell signal or speed input until this over-scale
alarm goes out, or modify the setting of FEED RATE OVER.
OFL4
This alarm comes on when actual load ratio exceeds the value set to LOAD RATIO
OVER. Reduce the magnitude of load cell signal until this over-scale alarm goes out, or
modify the setting of LOAD RATIO OVER.
OFL5
This alarm comes on when actual feed ratio exceeds the value set to FEED RATIO
OVER. Reduce the magnitude of load cell signal or speed input until this over-scale
alarm goes out, or modify the setting of FEED RATIO OVER.
