SECTION 3
3.9 Replacement of EPROM in the Plasmarc Power Source Programmable Logic
Controller (PLC)
CAUTION

CAUTION

WARNING
!
The Precision Plasmarc System may be shipped
configured for a manual flow control (Series "A"). If
so, the EPROM in the Programmable Logic
Controller must be replaced with an EFC EPROM.
This EFC EPROM is shipped with the power source.
Using the Wrong EPROM Could Result In
Damaged System Components
The Series "A" and the EFC EPROMs are
programmed with different software. The EFC
EPROM ignores the process gas pressure
switch inputs and does not include the
process gas purge required for the Series "A".
Mishandling Can Damage Electronic
Components.
Handle electronic components with care.
Do not drop
•
Do not bend pins
•
Do not touch circuit components- handle
•
along edges when possible
Electronic Components Are Subject To
Electro-Static-Discharge (ESD) Damage
Integrated Circuit parts are sensitive to over
voltages. The damage may not be seen
immediately but show up as a premature
failure.
The EFC EPROM is shipped in an anti-static
bag. Store EPROM in this bag.
Wear a protective ground strap when handling
sensitive electronic components.
Electric shock Can Kill!
Unplug power cable from wall to power source
before any connections or adjustments are
made inside power source.
