GROUNDING REQUIREMENTS
Proper grounding of weighing system components is essential to avoid
problems with static, transmission line “noise”, and voltage surges that may
damage the equipment. It is essential that M2000 Indicators have a good
ground connection.
STATIC ENVIRONMENTS
To reduce static interference, some weighing systems should have a solid
connection from the scale base
to Earth Ground.
This includes:
• Systems incorporating conveyors
• Systems incorporating Shrink-wrappers
• Other devices that produce a lot of static
• Devices used to weigh static-charged materials (such as plastics)
should also be grounded in this fashion.
LINE NOISE
To reduce line noise, connect the Loadcell shield wire to the Ground
terminal, labeled “GND”, on the back of the M2000.
(See M2000A Wiring Terminals – Page 21)
PLEASE NOTE THAT THE GROUNDING REQUIREMENTS FOR
THE M2000D DIGITAL SYSTEM ARE MUCH MORE STRINGENT!
FOR MORE INFORMATION ABOUT THE M2000D AND
LIGHTNING PROTECTION, SEE THE M2000D TECHNICAL
MANUAL OR CONTACT THE WESTERN SCALE FACTORY.
