3.1.3 Electrical Noise Interference
To prevent electrical noise interference, make certain all other wall outlets
for use with air conditioning and heating equipment, lighting or other
equipment with heavily inductive loads, such as welders, motors and
solenoids are on circuits separate from the indicator. Many of these
disturbances originate within the building itself and can seriously affect the
operation of the instrument. These sources of disturbances must be
identified and steps must be taken to prevent possible adverse effects on
the instrument. Examples of available alternatives include isolation
transformers, power regulators, uninterruptible power supplies, or simple
line filters.
3.1.4 Transient Suppression
The following recommendations will help to reduce transients:
Always use shielded cables to connect signal wires to the weight
indicator.
Secure the cables in the cable clips provided inside the indicator.
Connect the cable shield (indicator end only) to a ground point
inside the indicator. Keep wires that extend beyond the shield as
short as possible.
Do not run load cell or signal cables from the weight indicator
alongside or parallel to wiring carrying AC power. If unavoidable,
position the load cell and signal cables a minimum of 24" away
from all AC wiring.
Always use arc suppressors across all AC power relay contacts (see
recommendations at www.panconcorp.com/PDFs/capacitors/QRL-
Quencharc.pdf).
Use zero voltage switching relays, optically isolated if possible.
