Turn controller power off before servicing
tha
controls. This is to ensure safety and prevent damage
to the controller.

The
PSI0
and DSIO modules all
perform continuous diagnostic evaluations of the condi-
tion of the hardware. Proper operation of these modules
is indicated by LEDs (light emitting diodes) on the front
surface of the DSlOs and on the top horizontal surface
of the PSIO.
Red LED:
B/inking
c.ontinuous1.i.
at a 3 to 5 second rate indicates
proper operation
Lit
covzlinrrous/~r~
indicates a problem requiring replace-
ment of the module
Qf~corttinuous(~~
indicates the power
shouId
be checked.
If there is no input power, check fuses. If fuse is bad, check
for shorted secondary of transformer, or for bad module.
Green LED: (On a PSIO, this is the green LED closest to
the COMM connectors. The other green LED on the
module indicates external communications, when used.)
The green LED should always be blinking
when
patvcr
is on; it indicates that the modules are communicating
properly. If a green LED is not blinking, check
the
red
LED. If the red LED is normal, check the module address
switches. See Fig. 9. The proper addresses are:

the
DSl0
module.
All
system
operating inteiligcnce rests in the
PSI0
module (processor
moddej,
the modttlc that controls
the unit. This
mod&
monitors conditions through input
and output ports and through tire DSlO modules (low-
voltage relay module and I:XV
driv!er
module).
The machine operator communicates with the micro-
processor through
the
IIS
module (keyboard;!dinplay
module). Communication between
the
PSI0
and the
other modules is accomplished by a
3-vvire
~tn~or
bus.
These 3 wires run in
p~trallel
from module to module.
Each module in a panel is numbered (1. 2, 3,..). Each
terminal strip on a module is labeled (J2, J3,
.J4...).‘I’he
terminal strip number on the machine schematic com-
bines the module and strip numbers. For example, 253 is
terminal strip 53 on module 2. The module numbers can
be found on the component arrangement label.
