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 

Specifications

 on page 3 and 

Installation/Load Cell 

on page 6 for belt scale 

requirements and connection. 

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 

Specifications

 on page 3 and 

Installation/Speed Sensor 

on page 6 for speed 

sensor requirements and connection. 

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 

Analog Output 

on

 

page 43). 

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. 

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