Page 64 of 118 SGB Batch Blender with Mitsubishi Controller
• Calibration Error, Clean out hopper and check calibration: This
alarm indicates that the maximum empty weight for the weigh
hopper has been exceeded. The blender will automatically tare up
to 0.25 lbs of material, but if this weight is exceeded, then an alarm
will appear. This alarm is most commonly caused by a build up of
sticky material in the weigh hopper and can be corrected by simply
cleaning out the weigh hopper. If this does not correct the problem,
then the scale calibration should be checked by maintenance.
• Power Interruption while metering a Batch: This alarm indicates
that the blender’s power was turned off while the blender was
making a batch. The batch accuracy is not effected as long as the
blender is configured for “AutoStart.” The blender will finish the last
batch accurately even if the material was dumped into the mixer
when the power was turned off.
• PLC Battery Low: PLC battery is low and may cause the blender
to lose both the program and the blender configuration. Notify
Maintenance immediately.
• Inventory Cleared: This is only logged in the Alarm Log and does
not cause a pop-up message or audible alarm. Each time the
inventory is cleared, the time and date are logged to the Alarm Log.
An alarm will sound and a screen will pop up when Auto. Inventory
Shutdown has been reached.
