System Troubleshooting - Major Fault - “PLC Ext Off / Fault”
The PLC and the two extensions
are “the brains” of the Reclaim
System as noted in the overview
on page 39.
If this fault is noted on the touch
screen display, the pump
may or
may not shut down as a result
depending on which component
has failed. The Reclaim system will
not continue to operate correctly in
this condition.
Touching the yellow fault box on
the touch screen will take the
operator to the text seen in the
second screen
IF the PLC is not
the failed component and one or
both of the extensions is.
The control box door must be
opened to gain access to the
PLC and the two extension array.
There is a way to defeat the main
disconnect and leave the power on
to the internals of the control box
but this must only be attempted
by a factory trained technician.
High Voltage is present inside the
control box.
The picture to the left illustrates
a working set of the PLC /
Extensions indicated by the PLC
Screen Content and the green
LEDs on the extensions.
The extensions have a “lock”
that must be slid to the left to
connect electrically with the PLC
for programming. If a red light is
on the extension, try unlocking &
relocking the tab. There may be
dust or oxidation causing the issue.
The lower picture on the left
illustrates a non-working set of the
PLC / Extensions indicated by the
PLC Screen Content and the red
LEDs on the extensions.
