Installation

Installing/Replacing the Memory Back-up Battery

Disconnect power before installing or replacing the battery. Do not install the memory battery until the BW500 is to be used.

PL-565 Accumass BW500 Page 27

The unit is supplied with one battery package (battery P/N 20200035 or Rayovac #BR2335, 3V, Lithium or equivalent). Remove the battery from the package and insert it into the battery socket.

The memory battery (see Specifications) should be replaced every 5 years to insure memory back up during lengthy power outages. An on board capacitor provides 20 minutes of charge in order to preserve the memory while the battery is being changed.

Program Mode

General

• The BW500 operates under two modes: `run' and `program'. When the unit is initially powered, it starts in the program mode

• The program parameters define the calibration and operation of the BW500.

• By entering the program mode, the user can view the parameter values or edit them

to suit the application.

• The program mode display identifies the parameter by name and description and a list of options or instructions for making a valid entry.

Initial Start Up

Initial start up of the BW500 consists of several stages, and assumes that the physical and electrical installation of the belt scale and speed sensor, if used, is complete:

• power up

• programming

• load cell balancing

• zero and span calibration

Power Up

Upon initial power up, the BW500 displays:

The initial programming requirements are now satisfied. To insure proper entry of all critical parameter values, return to P002 and review parameters through to P017.

Load Cell Balancing

Balancing of the load cells is not required if the selected test reference is ECal (P002 = 3). In the case of ECal, the load cells are balanced by the ECal procedure.

If you are operating a two or four 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.

material has been totalized.

The initial programming is complete and the BW500 is operating in the Run mode. The belt conveyor can be put into normal service. The BW500 is functioning under its initial program and calibration, reporting rate of material flow and totalizing.

Start Up

If the initial entry and operation in the run mode is successful, the weighing system should undergo a recalibration by performing a series of material tests. Material tests will verify the BW500 reporting accuracy, and where inaccuracies exist, allow the system to be corrected through a manual span adjustment (P019).

Recalibration of the zero and span are ongoing requirements that must be performed routinely in order to maintain accurate reporting of rate and total.

Refer now to the Recalibration.

Belt Speed Compensation

Material Tests

Material tests are performed to verify the accuracy of the span calibration and compensate for the belt effects to material loading. 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.

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 their agent.

If the span adjust values are significant and repeatable, perform a manual span adjust:

Note:

Test weights are NOT used during material tests.

There are two methods of executing the manual span adjust: % Change and Material

Test

• % Change: based on the material test, the difference between the actual weight of material and the weight reported by the BW500 is calculated and entered into P019 as % change.

• Material Test: based on material test, the actual weight of material is entered into P019

The method of execution is a matter of preference or convenience, and either way yields the same result.

% Change

• Run the belt empty.

• Perform a zero calibration.

Put the BW500 into run mode Record the BW500 total as the start value _ _ _ _ _ _ Run material at a minimum of 50% of design rate over the belt scale for a minimum of 5 minutes.

Recalibration

Stop the material feed and run the conveyor empty. Record the BW500 total as the stop value _ _ _ _ _ _ Subtract the start value from the stop value to determine the BW500 total

• Weigh the material sample if not already known.

✍

BW500 total = _ _ _ _ _ _

material sample weight = _ _ _ _ _ _ ✍

Recalibration

In order to maintain the accuracy of the weighing system, periodic zero and span recalibration is 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.

The displayed deviations are referenced to the previous zero or span calibration. Deviations are continuously tallied for successive zero and span calibrations, and when exceed their limit, indicate an error messages that the deviation or calibration is out of range.

The duration of the auto zero is one or more belt revolutions (P360). If either condition is interrupted during that period, the auto zero is aborted and the run display is resumed. After one belt revolution, another auto zero will be attempted if the input and load conditions are met.

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 error message is displayed. The error message is cleared after five seconds, however if a relay is programmed for diagnostics, it remains in alarm so long as the Auto Zero conditions are being met.

If material feed resumes during an auto zero function, the totalizing function is maintained.

Routine Span

Note:

In order to obtain an accurate and successful calibration, ensure that the required criteria are met. Refer to Calibration Criteria on page 139.

for example, the last valid span count

The BW500 offers a multispan function, which allows the BW500 to be calibrated for up to eight different feed conditions that would produce varying load characteristics. Different feed conditions are typically related to the running of different materials or multiple feed locations. The varying load characteristic often has a bearing on the belt tension, and is observed especially when in close proximity to the scale. To accommodate such scale applications, a span correction can be made by selecting and applying the appropriate span.

Since every material has its own unique physical properties, and may load the belt differently, a span calibration may be required for each material in order to realize maximum accuracy.

In the case of different feeder locations, a span calibration may be required to match each feedpoint or combination of feedpoints.

Each time one of the eight conditions is in effect, the corresponding multispan is selected prior to putting the BW500 into the run mode. The selection is made by either changing the multispan operation number, accessed via P365, or by external contacts connected to the Auxiliary input, and programmed via P270.

In order to enable multispan operation, the following must be addressed.

If it is desired to do a span calibration for another condition, (i.e. span 3 to 8), access P365 and repeat these steps for each condition. However as with any initial span, it is recommended that the span calibration for each multispan be followed by a material test and factoring.

If remote span selection is desired, Auxiliary Inputs, 1 and/or 2 and/or 3, must be programmed in order to read the contact state as the span selection. Remote selection overrides keypad (or Dolphin Plus) selection. The auxiliary inputs override the key pad selection.

Linearization

Conveyor applications where the ideal belt scale location has been compromised, or where there is a high degree of variation in belt tension, typically cause the belt scale to report load non-linearly. The BW500 provides a linearizing function (P390 - P392) 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.

• Lift the belt off of the scale and suspend various test weights to the scale to verify

mechanical linearity. If the load reported by the BW500 at these tests is non-linear, a mechanical problem is indicated. Refer to the belt scale manual in order to resolve the non-linearity by improved installation or repair.

If it is determined that the non-linearity is due to the weighing application, and not the actual belt scale, apply linearization by performing the following:

• zero calibration

• span calibration at 90 to 100% of design rate

• material tests at 90 to 100% of design rate

• manual span adjust if required

• material tests at 1 to 5 intermediary flow rates where compensation is required.

Note:

Compensation points must be at least 10% of the design load apart.

• calculate the percentage compensation for each flow rate tested.

% compensation = actual weight - totalized weight x 100

totalized weight

where:

actual weight = material test totalized weight = BW500 total

Notes:

• After the compensation has been programmed into the BW500, a material test

should be run to verify the effect of linearization.

Recalibration

• If additional compensation is required, it must be based on new material tests

performed with the linearization turned off (P390 = 0).

Page 54 Accumass BW500 PL-565

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 15, 30 , 45, 60 and 75% of the design load. After performing a zero and a span calibration at 100% of the design load, followed by material tests and manual span adjust, five material tests were performed at 30, 60, 90, 120 and 150 t/h, as indicated by the BW500. The following data was tabulated. (This example is exaggerated for emphasis).

The material tests should be run at same belt speed, representative of normal operation; in this case 1.2 m/s. For each rate, record the corresponding load value by scrolling to the BW500 load display during running conditions or by calculation.

P390 = 1, linearization – on P391-01 = 6.94 point 1, load P391-02 = 13.89, point 2, load P391-03 = 20.83 point 3, load P391-04 = 27.78 point 4, load P391-05 = 34.72 point 5, load P392-01 = - 10.7 point 1, compensation P392-02 = 11.1 point 2, compensation P392-03 = - 5.1 point 3, compensation P392-04 = 8.7 point 4, compensation P392-05 = -6.0 point 5, compensation

Note:

Often only one point of compensation is required, usually at a low load value. In the prior example, if compensation was only required at 6.94 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.

P390 = 1 linearization on P391-01 = 6.94 point 1, load P391-02 = 20.00 point 2, load P392-01 = -10.7 point 1, compensation P392-02 = 0 point 2, compensation

Parameters

Page 88 Accumass BW500 PL-565

Operation

Load Sensing

In order for the BW500 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 BW500 is compatible with belt scales fitted with one, two or four strain gauge type load cells. In order to function with LVDT type load cells, an optional LVDT conditioning card is required.

Refer to Specifications on page 9, and Installation on page 13 for belt scale requirements and connection.

Speed Sensing

In order for the BW500 to calculate rate and hence totalize material flow along the belt conveyor, a speed signal representative of belt speed is required. For optimum accuracy of the weighing system, both constant and variable speed applications, a speed sensor is required. The design speed (P014) and speed constant (P015) need to be programmed.

In constant speed applications (no speed sensor), the BW500 can be programmed to provide an internal speed signal. This is achieved by entering the design speed (P014) and providing a contact closure across speed input terminals (17/18). The speed constant (P015) defaults to ‘jumpered’. This contact should change to open when the conveyor is idle to prevent errant totalization.

Operation

Refer to Specifications on page 9 and Installation on page 13 for speed sensor requirements and connection.

Modes of Operation

Run is the normal or reference mode of operation. It continuously processes the load and speed signals from the belt scale to produce internal load, speed and rate signals, which are in turn used as the basis for totalization, mA output, relay control, and communication data. The run display is programmed (P081) to scroll through rate, totalization (P647), load and speed; either manually by pressing the enter key, or automatically.

Operation

Damping

The program mode allows viewing and, with security permission (P000), editing parameter values. During program, run mode functions are still active, i.e.: rate, relay, mA output and totalization.

If the program mode is left idle for a period of ten minutes, it automatically reverts to the run mode.

Zero and span calibrations effectively halt the run mode while they are in progress. During this time, totalization ceases, and all mA outputs, except for PID, fall to zero.

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 rate, load and speed, respond to the damped value.

Damping consists of a first order filter applied to the signal (reading or output value), so long as the change in signal is within ±10% of the established reference value. If the signal deviation is greater than 10% of the reference value, the signal will jump immediately to that new value. This value will be the new reference.

For example:

A conveyor is running material at 3 t/hr. The damping value, P080 = 3, keeps the reading and associated output stable over the normal operating fluctuation; i.e. the rate varies within the filters active band, 2.7 and 3.3 t/hr. If the feed to the conveyor suffered a blockage and the rate dropped to 1.5 t/hr, the damping would be bypassed and the readings and output would immediately jump to correspond to the 1.5 t/hr rate, and establish a reference value of 1.5 t/hr. The active damping band is now set to ±10% about the 1.5 t/hr value, or 1.35 to 1.65 t/hr. If the blockage cleared itself slowly, i.e. the rate of increase was within the 10% active damping band; the rate readings and output would gradually increase at the damped value. The 10% band would continuously reestablish a new reference value as the rate of material progressed.

If mA damping (P220) is enabled (value other than 0), then the damping (P080) as it pertains to the mA function is overridden, and responds independently at the specified mA output damping rate (P220).

Note:

Damping (P080 or P220) is not applicable to the mA output when programmed for PID function (P201 = 4).

Page 90 Accumass BW500 PL-565

mA I/O (0/4-20 mA)

Output

The standard BW500 provides one isolated mA output. The output can be assigned (P201) to represent rate, load or speed. The output range can be set to 0 - 20 mA or 4 - 20 mA (P200). The 0 or 4 mA value corresponds to empty or zero condition, whereas the 20 mA value corresponds to the associated design value: rate (P011), load (P952) or speed (P014). The mA output can be limited for over range levels of 0 mA minimum and 22 mA maximum (P212 and P213 respectively). The output 4 and 20 mA levels can also be trimmed (P214 and 215 respectively) to agree with a milliammeter or other external mA device.

The mA output value can be tested to output a prescribed value using parameter P911. Refer to P911 on page 85.

The optional mA I/O board provides two additional mA outputs, programmable as outputs 2 and 3, using the same parameters as the standard output (1). If programmed for PID control, output 2 is assigned to PID control loop 1 and output 3 is assigned to PID control loop 2.

Input

Operation

The optional mA I/O board provides two mA inputs, programmable as inputs 1 and 2. If programmed for PID control, generally, input 1 is assigned to PID control loop 1 and input 2 is assigned to PID control loop 2.

The input range can be set to 0-20 mA or 4-20 mA (P250), and assigned a function (P255), e.g. PID setpoint. The 4 and 20 mA levels can be trimmed (P261 and P262) to agree with an external device.

Relay Output

The BW500 offers five single pole single throw (SPST) relays that can be assigned (P100) to one of the following alarm functions:

• rate: relay alarms on high and/or low material flow rate.

• load: relay alarms on high and or low belt load.

• speed: relay alarms on high and/or low belt speed.

• diagnostic: relay alarms on any error condition as it is reported.

• PID: PID control setpoint deviation*

• batch pre-warn

• batch setpoint

Refer to Troubleshooting on page 137.

*is offered only if the PID system (P400) is enabled.

For rate, load and speed alarm functions, the high and low alarm setpoints (P101 and P102 respectively) are required and must be entered in the appropriate units. The high alarm setpoint acts as the setpoint deviation alarm for relays programmed for PID setpoint deviation.

PL-565 Accumass BW500 Page 91

The on / off actuation at both high and low setpoints is buffered by the damping (P080) and the programmable dead band (P117), to prevent relay chatter due to fluctuations. The relay is normally energized; holding the normally open (n.o.) contact closed (can be programmed for reverse operation, P118). Upon an alarm condition, the relay is de-energized and the relay contact is opened. Once in alarm, the relay remains in alarm state until the alarm condition is removed.

Operation

Example:

P014 = 2m/s, design speed P100 = 3, belt speed P101 = 100% (2 m/s) P102 = 20% (0.4 m/s) P117 = 2% (0.04 m/s)

high 100%

actual low alarm

low 20%

‘off’ = 22%

‘on’ = 20%

alarm `on' is with relay de-energized

Totalization

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.

The BW500 provides several separate totalizer functions:

Internal totalizers:

• local display (totalizers 1 and 2)

• verification totalizer (totalizer 3)

• material test totalizer (totalizer 4)

• batch total (totalizer 5)

External totalizers

• totalizer outputs (remote totalizers 1 and 2)

Page 92 Accumass BW500 PL-565

To avoid totalizing material at flow rates below the low flow rate limit, the totalizer drop out limit (P619) is set to a percentage of the design load. Below this limit, totalization stops. When material flow returns to a rate above the drop out limit, totalization resumes.

Totalizer resolution or count value is set by the respective internal (P631) and external (P638) totalizer* resolution parameters.

*If the resolution selected causes the totalizer to lag behind the count rate, the next possible resolution is automatically entered.

e.g.: Internal totalizer 1

given: P005 = 1 (t/h)

P631 = 5

then: totalizer count increments by 10 for each 10 metric tonnes registered

External totalizer 1

given: P005 = 1 (t/h)

P638 = 5

then: contact closure occurs once for every 10 metric tonnes registered

Operation

For remote totalization, the contact closure duration (P643) is automatically calculated upon entry of the design rate (P011) and remote totalizer (P638) parameters, so that the duration of contact closure allows the relay response to track the total up to 150% of the design rate. The value can be changed to suit specific contact closure requirements, such as in the case of programmable logic controllers. If the duration selected is inappropriate, the next possible duration is automatically entered.

The totalizers are reset through the master reset (P999), the totalizer reset (P648) or through the keypad.

• master reset: the reset of all totalizer functions is included in the master reset.

• totalizer reset: totalizer reset can be used to resets internal totalizers 1 and 2, or

totalizer 2 independently. Resetting the internal totalizers 1 and 2 resets the internal registers for external totalizers 1 and 2.

• keypad: pressing

while in the run mode resets internal totalizer 1

Placing the internal totalizers on to the display scroll of the run mode is controlled by the totalizer display parameter (P647); displaying either one or both totalizers.

Page 94 Accumass BW500 PL-565

PID Control

The PID control algorithm in the BW500 is designed specifically to work for feed rate control applications. It is based on motor control type algorithms and includes several anti-wind up provisions.

One way to prevent wind up is to monitor the input speed frequency from the weighfeeder. If the input frequency drops below 5 Hz, the PID control output freezes at its current value. Otherwise, the output winds up to 100% if the feeder is shut off while there is still a set point greater than zero. When the feeder is turned back on, there would be a surge of product flow until the system regains stability. With antiwind up, the feeder can be stopped and started with minimal disruption to the controlled flow rate.

Setup and Tuning

Before proceeding, it would be beneficial to qualify and quantify the terms you will encounter in the setup and tuning of the control system.

Proportional Control (Gain), P

The P term on the BW500 adjusts the control output based on the difference between the set point and the measured flow rate. A higher P term makes the BW500 more sensitive and faster to react to changes or disturbances. If set too high, the BW500 becomes less stable, and more susceptible to oscillations in the control output.

• allowable input range: 0.000 to 2.000

• typical operating range: 0.300 to 0.600

• default value: 0.400

PID 2

(P201-03 = 4)

PID 1 remote setpoint load (P255-01 = 1)

PID 2 remote setpoint rate (P255-02 = 1)

The control output cannot reach the setpoint using only the P term. Since the P term acts on the difference between the setpoint and process variable, a small difference between these two always exist and the difference is never zero. A small P term can get the process very close to set point, but it would take a very long time. At the very least, an I term is required to eliminate the offset created by the P term.

Page 98 Accumass BW500 PL-565

Integral Control (Automatic Reset), I

The I term on the BW500 is used to increase or reduce the amount of control output to eliminate the offset caused by the P term. The I term acts on the accumulation of the error over small increments of time. As the process reaches setpoint and the error becomes small, the effect of the I term decreases. A higher I term makes the BW500 faster to react to changes, but can also make it less stable.

• allowable input range: 0.000 to 2.000

• typical operating range: 0.100 to 0.300

• default value: 0.200

The P and I terms together can make a suitable control algorithm and for many applications, they work fine. However, if faster response to changes is desired, it is necessary to use larger P and I terms. Unfortunately, larger terms can make the system unstable. A derivative term is needed to influence the control output as the process variable approaches the set point.

Derivative Control (Pre-Act or Rate), D

The D term on the BW500 influences the control output based on changes in the magnitude and direction of the change in error. If there is a constant error, the D term has no effect. As the error gets larger, the D term combines with the P term to make the BW500 control output respond faster. When the error is getting smaller, the D term acts to reduce the amount of control output to help prevent overshooting the set point. In general, a higher P term will require a larger D term.

• allowable input range: 0.000 to 1.000

• typical operating range: 0.010 to 0.100

• default value: 0.050

The result of the derivative action is that it can make a system more responsive and more stable at the same time.

PID Control

Feed Forward Control, F

On the BW500, the F term is used to adjust the control output based on a setpoint change. The use of this term can make the system reach the new setpoint faster. If the term is not used, the system responds using the P, I and D terms only. The difference between the new setpoint and the process variable is the error and the control algorithm responds to eliminate this new error.

When the F term is used and a new setpoint is entered, a proportion of the difference between the new setpoint and the process variable is automatically added on to the control output. This shifts the process variable closer to the new setpoint faster than using the P, I and D terms alone. This is done on a one time basis.

• allowable input range: 0.000 to 1.000

• typical operating range: 0.250 to 0.550

• default value: 0.300

The PID control function of the BW500 can be configured to operate in several modes.

• controller output: direct acting

• feedback: rate, load or external

• control: local or remote (ratio) setpoint

PID Setup and Tuning

Proper tuning of the control PID terms is essential to system operation and optimum performance from the feeder. The recommended procedures for tuning the PID control terms at initial start-up are described in this section.

Initial Start-Up

Although the default values of the P, I, D and F terms will suit the majority of applications, shearing weigh feeders in particular, some tuning will be necessary nonetheless.

There are several techniques and procedures for tuning conventional PID controllers, some work better depending upon the application. We recommend using "closedloop cycling" for the BW500 integrator/controller for feed rate control. This technique focuses on tuning the P term first while disabling the I and D terms. This is followed by adding and tuning the I term, then the D term. To outline this procedure:

1. With the P term set to its default value of 0.400, disable the I, D and F terms by setting them to 0.000.

2. Enter a feed rate setpoint that is 30% of the designed maximum flow rate.

3. Having applied the test weights or chain provided, start the feeder and observe the time it takes the feeder to reach setpoint, also observe the oscillation around setpoint.

4. Adjust the P term accordingly for consistent oscillation and error. Progressively decrease the P term value if there is too much oscillation and error. Likewise,
