Switch Faults
The ram and can each have proximity switches at both ends of travel (some have one, others two
or more in series). If the proximity switches on opposite ends of travel are made at the same time
(i.e., there are contradicting indications), the microprocessor stops automatic operation and dis-
plays a switch fault (SF) error message. The error is usually caused by a proximity switch that
was damaged when a moving device struck the face of the switch. Usually, the malfunctioning
switch is opposite the current position of the moving device. Ensure proper operation of the
switches involved, and replace the switches if necessary. Once the switch error is cleared, press-
ing
puts the press in manual mode.
NOTE: Once a switch fault has been seen by the computer, it is "latched in" or remem-
bered. Therefore, even a momentary switch malfunction will cause a switch fault.

Explanation
Indicates a peripheral board is not communicating with the con-
troller. Where <XXXXX> is either I/O #x, OUT #x, D to A, or A
to D. This error may result from incorrectly configuring this ma-
chine, having improper address (see schematic) on the board iden-
tified, or having one or more loose wire connections to or from
the board. Press
. Verify that configure decision values match
the equipment. Verify that the switches on the board referenced on
the display are set to the correct address. Check the wires to and
from the board. If the error persists, replace the board.
Explanation
The can full up and one of the can full down inputs were made
at the same time.
The ram at unload input was made while the ram full down was
not made. The ram at unload input implies that the ram full
down input should also be made.
The ram half up input was made while the ram at unload input
was not made. The ram half up input implies that the ram at un-
load input should also be made.
The ram full up input was made while the ram half up input was
not made. The ram full up input implies that the ram half up in-
put should also be made.
The discharge door up and down inputs were made at the same
time.
