Milltronics BW100

Introduction

Note: The Milltronics BW100 is to be used only in the manner outlined in this

instruction manual.

The Milltronics BW100 is an economical integrator for use with belt scales. The speed
and load signals from the conveyor and scale, are processed to derive rate of material
flow and totalization.

The primary values of speed and load, and the derived values of rate and total are
available for display on the local LCD, or as output in the form of analog mA, alarm relay
and remote totalization. BW100 supports Milltronics proprietary bipolar current loop for
long distance communication to PLC or computer. It is also compatible with Milltronics
Dolphin interface for remote display, programming and software upgrading.

Milltronics BW1 00 Features

• multi-field LCD display

• two remote totalizer contacts

• current loop for communications

• Dolphin compatibility

• programmable relay

• isolated mA output

• rate linearization

• local keypad

•Auto Zero

Load Cell Balancing

If you are operating a two 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 Tests

Perform material tests 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 (P017) value, yielding more accurate span recalibrations.

Note: Test weights are NOT used during material tests.

1. Run the belt empty.

2. Perform a zero calibration.

Design Changes

Where parameters have been changed with a resultant impact on the calibration or do
not take effect until a recalibration is done, the parameter warning icon is displayed. In
order to clear the icon, perform a zero and span recalibration after the reprogramming
session is complete.

If significant changes have been made, an initial zero (P377) and/or initial span (P388)
may be required.

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.

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 non­linearly. 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:

1. Run the conveyor belt empty and stop it.

2. Suspend various test weights to the scale to verify mechanical linearity. If the load
reported by the BW100 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 3 intermediary flow rates where compensation is required.

Notes:

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

• E8 message occurs if a point is less than 10% of full scale or if points are less
than 10% apart.

• calculate the percentage compensation for each flow rate tested.
% compensation = actual weight - totalized weight x 100

Where: actual weight = material test

totalized weight = BW100 total

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).

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
BW100 load display during running conditions or by calculation.

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

Operation

Load Sensing

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
requirements and connection.

Specifications

on page 3 and

Installation/Load Cell

on page 6 for belt scale

Speed Sensing

In order for the BW100 to calculate rate and hence totalize material flow along the belt
conveyor, a speed signal representative of belt speed is required. In constant speed
applications (no speed sensor), the BW100 can be programmed to provide an internal
speed signal. This is achieved by entering the design speed (P014) and providing a jumper
across speed input terminals (TB1-5/6). Speed constant (P015) defaults to 100.

For optimum accuracy of the weighing system, both constant and variable speed
applications, a speed sensor is required. Again, the design speed and speed constants
need to be programmed, however the jumper across the speed input has to be removed
and the speed sensor connected.

Refer to
sensor requirements and connection.

Specifications

on page 3 and

Installation/Speed Sensor

Modes of Operation

RUN is the normal or reference mode of operation. It continuously processes the load
signal from the belt scale to produce internal load and rate signals, which are in turn used
as the basis for totalization, mA output and relay control. The RUN display is programmed
(P081) to scroll through rate, totalization, load and speed; either manually by pressing the
ENTER key, or automatically. A bar graph is continuously displayed. It is proportional to
the analog output as programmed (see

From the RUN mode, access to the PROGRAM mode on and zero and span calibration is
made.

The PROGRAM mode allows viewing and, with security permission (P000), changing
parameter values. During PROGRAM, RUN mode functions are still active, i.e.: rate, relay,
analog output and totalization. Error interrupts are suppressed and the bar graph is
disabled.

mmmmm

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

Recalibration

Analog Output on

page 43).

Damping

Damping (P080) controls 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.

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

Analog Output

The BW100 provides one isolated analog 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 analog 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 P215 respectively) to agree with a millammeter or other external mA
input device.

Operation

mmmmm

The BW100 LCD provides a bar graph as a function of analog output. It displays the mA
value as percentage of the mA range.

The mA output value can be tested using parameter P911. Refer to
page 62.

7ML19985DJ01 Milltronics BW100 - INSTRUCTION MANUAL Page 43

Relay Output

The BW100 offers one single pole double throw (SPDT) relay that can be assigned (P100)
to one of the following alarm functions:

mmmmm

Operation

• 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

Troubleshooting

, page 65.

Except for alarm on ‘auto zero’ and ‘error’, the high and low alarm setpoints (P101 and
P102 respectively) are required and must be entered in the appropriate units.

The on / off actuation at both 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; i.e. the normally closed (n.c.) contact held open. Upon an alarm
condition, the relay is de-energized and the alarm icon on the BW100 display appears.
Once in alarm, the relay and icon remain in alarm status until the alarm condition is
removed.

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 BW100 provides four separate totalizer functions:

• internal totalizer 1

• internal totalizer 2

• remote totalizer 1

• remote totalizer 2

To avoid totalizing material at low flow rates, the totalizer drop out limit (P619) is set to a
percentage of the design rate. 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 control parameters, P631 -­P639. If the resolution selected causes the totalizer to lag behind the count rate, an E2
error is displayed after making the parameter entry. The error is rectified by selecting a
greater resolution value.

Example: Internal totalizer 1

Operation

mmmmm

Given: P005 = 1 (t/h)

P631 = 4

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

For remote totalization, the contact closure duration is set by the respective control
parameters, P643 and P644. The value is automatically calculated upon entry of the
design rate (P011) and remote totalizer parameters (P638 and P639), so that the duration
of contact closure allows the relay response to track the total up to the design rate. The
value can be changed to suit specific contact closure requirements, such as in the case
of programmable logic controllers. If an E2 error is displayed, P638 or P639 has to be
increased.

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

Milltronics Dolphin software. It is recommended that a reset (P999) is done after the
software update followed by zero and span calibrations.

Direct zero entry (P367) and direct span entry (P368) will suffice in lieu of dynamic zero
and span calibrations. Therefore, zero and span counts should be recorded prior to doing
the software update.
