BALANCE If you are operating a dual load cell belt scale, it is recommended that the load cells be balanced electronically prior to initial programming and calibration, or after either or both load cells have been reinstalled or replaced. Unbalanced load cells adversely affect the performance of your belt conveyor weighing system. test weight bar Belt Travel typical dual load cell scale With the conveyor stopped and locked out, lift the belt off the weighing idlers.
Place the BW100 into the program mode at P291.
QUICK START Quick Start parameters (P005 to P017) must be programmed for all applications. Have your design data sheet or program record handy! units design rate design speed speed constant belt length test load Upon completion of Quick Start programming, a Zero and Span calibration are required for successful entry into the run mode.

Calibration Note The duration of Zero and Span Calibration is dependent upon speed (P014), length (P016) and revolutions (P360) of belt. To cancel a Zero or Span calibration in progress, and return to the run mode.
Zero Calibration Run the conveyor for several minutes to warm up the belt and insure that it is empty. Test weights are not used during a zero calibraion.

RECALIBRATION BELT SPEED COMPENSATION In order to achieve optimum accuracy in the rate computation, the belt speed displayed must equal that of the actual belt speed. As the speeds are likely to differ, a belt speed compensation should be performed. Run the conveyor with the belt empty. run mode \ speed display, e.g. 0.750 m/s View the belt speed. Stop the conveyor and measure a length of the belt; marking the forward end (start time) and the back end (stop time).
MATERIAL TESTS Material tests are performed to verify the accuracy of the of the span calibration. If the material tests indicate a repeatable deviation exists, a manual span adjust (P019) is then performed. This procedure automatically alters the span calibration and adjusts the test load (P17) value, yielding more accurate span recalibrations. Test weights are NOT used during material tests. » Run the belt empty. » Perform a zero calibration.
If the span adjust value is within the accuracy requirements of the weighing system, the material test was successful and normal operation can be resumed. If the span adjust value is not acceptable, repeat the material test to verify repeatability. If the result of the second material test differs considerably, consult Milltronics or its agent.
RECALIBRATION In order to maintain the accuracy of the weighing system, periodic zero and span recalibrations are required. Recalibration requirements are highly dependent upon the severity of the application. Perform frequent checks initially, then as time and experience dictate, the frequency of these checks may be reduced. Record deviations for reference. Routine Zero Run the conveyor empty for several minutes to warm up the belt and insure that it is empty.
Initial Zero An initial zero can be performed if deemed as a proper response to E3 message. Refer to maneuvering for parameter selection and value change.
Direct Zero Direct zero entry (P367) is intended for use when replacing software or hardware, and it is not convenient to perform an initial zero at that time. A record of the last zero count is required. Refer to maneuvering for parameter selection and value change.
Routine Span To perform a routine span recalibration, run the conveyor until the belt is empty and stop it. Suspend the test weights from the belt scale per its instruction manual. Run the conveyor empty at maximum operating speed .
Initial Span An initial span can be perform if deemed as a proper response to E4 message. Refer to maneuvering for parameter selection and value change.
Direct Span Direct span entry (P368) is intended for use when replacing software or hardware, and it is not convenient to perform an initial span at that time. A record of the last span count is required. Refer to maneuvering for parameter selection and value change.
Factoring In order to calculate the value of a new or unknown test weight to the current span, the factoring procedure is used. For optimum accuracy in the factoring results, a routine zero calibration is recommended. Refer to Maneuvering for parameter selection and value change. With the conveyor stopped and the belt empty: P359 selected enter initiated Factoring, current test load value e.g. 76.11 kg / m hang new test weight onto belt scale, then run the conveyor empty dynamic test load value e.g. 76.
Linearization Conveyor applications where the belt scale is poorly located, or where there is a high degree of variation in belt tension, typically cause the belt scale to report load non-linearly. The BW100 provides a linearizing function (P390 - P396) in order to correct for the deficiency in the weighing system and to provide an accurate report of the actual process. To verify that the cause of the non-linearity is not mechanical: » run the conveyor belt empty and stop it.
Example : A non-linearity with respect to the ideal response exists in a belt scale application with design rate of 200 t/h. It is decided to do material tests at 25, 50 and 75% of the design rate. After performing a zero and a span calibration at 100% of the design rate, followed by material tests and manual span adjust, three material tests were performed at 50, 100 and 150 t/h, as indicated by the BW100. The following data was tabulated. (This example is exaggerated for emphasis).
Program the BW100 as follows: P390 = 1 P391 = 11.6 P392 = - 14.3 P393 = 23.2 P394 = 10.5 P395 = 34.7 P396 = - 8 Often only one point of compensation is required, usually at a low load value. In the prior example, if compensation was only required at 11.6 kg/m, the programming could be as follows. Compensation is optimized by establishing the next load value that agrees with the material test, hence where compensation is zero and entering it as the next compensation point.
RECALIBRATION 48 PL-531
OPERATION In order for the BW100 to calculate rate and hence totalize material flow along the belt conveyor, a load signal representative of weight of material on the belt is required. The load signal is provided by the belt scale. The BW100 is compatible with belt scales fitted with one or two strain gauge type load cells. Refer to Specifications and Installation\Load Cell for belt scale requirements and connection.
DAMPING OPERATION Damping (P080) provides control over the speed at which the displayed readings and output functions respond to changes in their respective input function; load, speed and the internal rate signals. Changes in the displayed rate of material flow, material loading and belt speed are controlled by the damping. Relay alarm functions based on input functions of flow, load and speed, respond to the damped value.
RELAY OUTPUT » rate: relay alarms on high and/or low material flow rate. » auto zero: relay alarms when an attempted auto zero calibration reports an out of range condition (E9). » speed: relay alarms on high and/or low belt speed. » load: relay alarms on high and or low belt load. » error: relay alarms on any error condition as it is reported. Refer to Appendices \ Troubleshooting.
TOTALIZATION OPERATION The totalization function is based on the internal rate (mass per unit time) signal proportional to belt speed and load on the associated belt scale. It is not affected by the damping function (P080). The rate signal is sampled several times a second to accurately count the mass of material conveyed. The count is held in the master totalizer used to increment the internal totalizers and to produce a pulse signal for the remote totalizers.
AUTO ZERO - the auto zero input (TB1-9/10) is in a closed state; jumper or remote switch - the load is less than 2% of the design load If the resulting zero deviation is less than an accumulated 2% from the last operator initiated zero, the auto zero is accepted. If the deviation is greater than an accumulated 2%, an E9 error is displayed and the relay, if so programmed, goes into alarm (refer to Operation\Relay Output). The E9 error is cleared after five seconds.
PROTOCOL OPERATION Protocol refers to the format, sequence and value of the data fields used in communication messages. Each data field of a BW100 message contains one or more bytes of ASCII binary code. Each byte contains: » 8 data bits » no parity bit » 1 stop bit DATA FIELD DESCRIPTIONS The following data fields are used. som BW100 start of message, ASCII character = STX (Hex Value = 02). DEVICE Identifies the BW100 to which the message applies.
