ABOUT THIS MANUAL
It is essential that this manual be referred to for proper installation and operation of
your BW100 belt scale integrator. As BW100 must be connected to a belt scale, and
optionally a speed sensor, refer to their manuals as well.
Installation gives you step by step direction for the installation and
interconnection of your BW100.
Start Up instructs you how to operate the keypad, read the display, do a
Quick Program, and perform the calibration for a successful entry
into the run mode.
Recalibration emphasizes how to optimize and maintain accurate operation of your
weighing system through material tests and routine recalibrations.
Operation offers an overview of the BW100 features and functions that allow
you to take full advantage of your weighing system.
Parameters lists the parameters available to you, with a description of their
function and use. You are urged to read this section; to familiarize
yourself with the parameters available to you and get your BW100
working to its fullest.
Appendices what manual would be complete without one! Ours has an
alphabetical cross reference of the parameters to their numbers, a
diagnostic help with the list of error messages, a maintenance
reminder, and a record sheet for jotting down parameter values.

ABOUT THE ACCUMASS BW100
The ACCUMASS BW100 is to be used only in
the manner outlined in this instruction manual.
The ACCUMASS BW100 is a microprocessor based integrator designed for use
with Milltronics, or equivalent belt scales. The speed and load signals from the
conveyor and scale, respectively, 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 via BIC-2, RS -232 or RS -422 converter. It is also
compatible with Milltronics Dolphin interface for remote display, programming and
software upgrading.
ACCUMASS BW100 features:
✓multi-field LCD display
✓two remote totalizer contacts
✓current loop to RS-232 or RS-422
✓Dolphin compatibility
✓programmable relay
✓isolated mA output
✓rate linearization
✓local keypad
✓auto zero

SPEED SENSOR
▼Connect the BW100 TB1 – 7 to the MD - 36A speed sensor terminal:
‘2’ for clockwise speed sensor shaft rotation
‘3’ for counter-clockwise speed sensor shaft rotation.
MD - 36A shaft rotation is viewed from the front cover side
of the MD - 36A enclosure.
▲If a speed sensor is not used, a jumper must be connected across the BW100
TB1 – 5 / 6. If a speed sensor is used, insure that the jumper is removed.
◆Input device in the form of open collector transistor or dry contact across
TB1 – 6 / 7 will also serve as a suitable speed signal.
