5.4 TRUCK SEAT GROUNDING
5.4.1 Static Electricity and Grounding
Static electricity can build up on drivers
and truck seats, especially during cold,
dry weather. Adjustable, shock-
absorbing seats add to the problem
because they isolate the seat cushion
from an electrical ground. If the static is
discharged on or near the LectroCount
3
,
it can cause the truck computer to reset
and/or cause a number of other hard to
trace faults. The discharge can occur
when the driver touches the
LectroCount
3
or a part of the truck that
provides a good ground path.
WARNING
To prevent the occurrence of electrostatic discharge (ESD), it is
mandatory that the truck seat(s) be properly grounded. This allows
the static electricity to “bleed off’ the driver and seat before it can
build up to the point where a discharge can interfere with the
operation of the LectroCount
3
(or cause an explosion in hazardous
environments!)
