The motor control circuit board, the communication
circuit board and the application circuit board contain
their own separate firmware. If any of these boards are
replaced, they must be programmed in Autocheck.
The other circuit boards do not have any firmware, and
do not need to be programmed after a replacement.
CAUTION: Pull the connector and not the cable.
CAUTION: Do not touch the components or pin
terminals on the circuit board.
CAUTION: If the circuit board is to be checked
in order to evaluate the warranty, it must be
placed in a bag with protection against ESD
(electrostatic discharge).
CAUTION: Always protect the product from
electrostatic discharge, ESD, before you start to
work on electrical components.
