This screen shows the X-OVER is on, thus one drum
is active and the other is on standby, ready when the
drum goes low. Turn the X-OVER off by pressing F4
(OFF).
While the X-OVER is running and a drum goes low, it
will need to be changed. Once the EMPTY limit switch
is activated on an unloader, the RED light will be
activated (as well as the AMBER light because the
LOW limit switch is also activated). The X-OVER
active drum will change to the other unloader, indicated
by the GREEN light on the beacon assembly, and the
pendant will keep the heat zones of the empty drum on
for 59 min. This allows time for the operator to change
the drum while it is still hot. After 59 min, the zones will
automatically turn off on the EMPTY drum. This
X-OVER screen will change as follows to prompt the
operator to change the drum.

As shown, the X-OVER screen will give the operator
the prompt to change a drum. Pressing F1 will restart
the heat zones of DRUM A, turn on the air solenoid
and allow the operator to change the drum once all
heat zones are within temperature limits of all ACTIVE
zones. Once F1 is pressed, the X-OVER will change
again, requiring the operator to acknowledge that the
drum change is complete.

The F1 key has now changed to F1 (DONE). When
the drum has been changed and ready with new
material, pressing F1 (DONE) will stop the heat zones
dedicated to UNLOADER A, and shut off the air sole-
noid to UNLOADER A. The prompt for changing the
drum will no longer show on the X-OVER screen.
