4. Operating Instructions
Weigh Mode Alarms
Your On-Board Weighing System is equipped with both a
hardware and software alarm to alert the operator when the scale
is in the weigh position. When the M2000 is ON the system
automatically monitors the weight on the scale. When the scale is
up the system software will automatically flash the alarm light
located in the cab of the truck, on truck mounted models. The
alarm light is located on the side of the control box on trailer
mounted units. When the scale is lowered into the transport
position the software automatically turns the alarm lamp off.
As a backup to the software alarm, the system also uses a
hardware alarm that will function even when the power switch is
in the OFF position. When the M2000 is off the system can no
longer monitor the weight on the scale. Instead a hardware alarm
monitors the position of the scale. If you cut the power to the
system with the scale is in the weigh position, the alarm light will
turn on solid. The alarm light will remain on until the scale is
lowered into the transport position.
8
Operating Modes
The Weigh Center operates in two modes: Single weigh mode
and Batch weigh mode.
Single Weigh Mode is a simple mode that allows only independent
scale weight tickets. Product ID’s are not available in this mode.
Batch Weigh Mode is a mode with more functionality. It allows
the use of product ID’s so that more than one product can be
delivered and weighed (multiple compartment containers).
To change the mode, enter the following keystrokes into the
M2000:
The M2000 will then prompt ‘config’ on the display. To function
in single weigh mode enter the following keystrokes:
To function in batch weigh mode enter the following keystrokes:

5. Maintenance
Weekly
- Check entire scale for build up of debris. If any debris is
found under the scale frame or around the Load Cells
remove it immediately.
- Visually check all external cables and conduit for damage.
Check and ensure the load cell cables are free to move
with the load cell.
- Check hydraulic cylinders and lines for leakage and ensure
they will not prevent the scale from moving freely. If a
cylinder or hose is leaking replace it as soon as possible. A
leaking cylinder may cause the scale to settle and give
inaccurate readings during a transaction.
- Raise and lower the scale to ensure the up/down alarm is
working properly.
- Check the lock down bolt adjustment.
The lockdown bolts should be adjusted so that the
hydraulic cylinders are extended minimum 1/8” to
maximum 1/4” when the system is locked down. As well,
the load cells should be loose in the lock down position.
To adjust the lock downs, loosen the jam nut on the lock
down bolt. With the jam nut loose adjust the lock down
bolts so that the cylinders are extended between 1/8” and
1/4”. Check the load cell and ensure it is loose. If you are
unable to achieve an adjustment where the cylinder is
slightly extended and the load cell is loose contact you
scale dealer.
26
27
Yearly
- Do all required weekly services checking all components
of the system.
- Park system on a slope greater then seven degrees and
raise the scale. (For example a steep approach.) Turn on
the indicator and check to see if it shuts off in 10 seconds.
If the indicator does not shut of you may have a faulty tilt
sensor, consult you local scale dealer. You must do this
test in all four directions, front low, rear low, right side
low and left side low.
- Disassemble each load cell location. Check all bushings for
excessive wear and replace if necessary. Grease the ends
of the upper load cell pin and lower eyebolt when
reassembling.
Note: Use quality high-pressure grease.
Note: Avoid bending or twisting the load cell wires.
To perform service on any of the scale parts (i.e. load cell,
bushings), the linkage assembly must be disassembled. The
following procedure must be followed when disassembling any
linkage.
