Additional Calibrations
When the machine is equipped with the Production Measurement Application, additional calibrations are available within the monitoring system. The additional calibrations are located in the Service Menu under the Payload calibration list.Simple Calibration
The simple CAL update provides a method for fine-tuning the PCS. Fine-tuning the scale system accounts for a constant offset error between the scale system and the weights recorded by the scale house. A constant offset error could be caused by the following events:
Spillage of material during calibration before the calibration weight is weighed.
Incorrect entry of the calibration weight into the display
Spillage of the material during the loading of the materialNote: The machine cannot be turned OFF while a simple CAL update is being performed. If the machine is turned off, all information that was previously stored for the update will be lost. The lost information includes the history of trucks that were loaded.The simple CAL update requires the actual weights of the scale house for ten truck loads that have been loaded with scale system. The tare weights of these ten loads must be accurate. If the tare weights are not accurate, performing the simple CAL update could have adverse effects on the accuracy of the system.Note: The simple CAL update cannot be performed unless the operator presses the store button after each truck load.In order to perform a simple calibration, record the weights on ten trucks at the scale house and the weight that is displayed by the scale system for the ten trucks. The scale house weights will be entered into the scale system during the simple process for calibration. Perform the following in order to access the simple CAL update:
Select the service menu.
Select the Calibrations menu.
Select the Payload menu.
Select the Simple Calibrations menu.The display shows up to 15 truck loads. The trucks are listed in the order of loading.Note: The first 15 truck loads that are shown on the display are the truck loads that were loaded immediately after powerup. If more than 15 trucks have been loaded after powerup, only the 15th truck on the display gets replaced with the most recently loaded truck.When the simple calibration update has started, the most recently loaded truck will be displayed at the bottom of the list. When auto truck ID is enabled, the following will match:
The Truck ID that is in the list
The Truck ID that was assigned to the truckNote: The assignment was made when the store switch was pressed. The following occurs when the auto truck ID feature is disabled:
The truck ID will change to the next truck in the list after the store switch is pressed.Following is an example of the operation:
The first truck that is loaded after powerup will be "Truck 1".
The second truck will be automatically incremented to "Truck 2".
The most recent truck that was loaded will have the highest number.To continue the simple calibration update, perform the following actions:
Select the truck that corresponds to the last weight that was reported.Note: Verify that the truck loads match
