[XXXX] Amp Temperature
The motor control amplifier has overheated due to
excessive load. Allow the amplifier to cool for sev-
eral minutes, then try again.
[XXXX] Bad Position Report
The gage responded with an actual position that
was different from the commanded position.
SYSTEM ERRORS
The following steps should be performed if a fault
occurs.
1. If the control does not respond to softkey press-
es, check to see if any other panel controls
respond including the Main Drive ON/OFF,
Ram Up, front panel pushbuttons (MODE
SELECT, STROKE STOPS, FORM SPEED
SELECT).
Note: Locate a qualified electrician to perform Steps
2, 3 and 4.
2. Open the main electrical cabinet without turn-
ing the main disconnect off. This can be done
by using a flat-bladed screwdriver to turn the
screw located on the door latch mechanism as
the latch is opened.
3. Locate the CPU board inside the cabinet. It will
be the only board which has a red LED display
digit. It can also be identified by the memory
cartridge extending about 4 inches off the
board with stand-offs. Look at the LED display
and note whether there is a rotating zero pat-
tern or if it has stopped.
4. Close the electrical cabinet and cycle the power
by turning off the Main disconnect, waiting
about 15 seconds then powering it back on.
5. Press a key on the front panel and look at the
screen to see if the SYSTEM ERROR screen is
shown. If it is not displayed, go to the DIAG-
NOSTIC screen and press the “System Error”
softkey. Record the information on the SYS-
TEM ERROR screen as shown.

POWER-UP TEST ON CPU BOARD
The following section describes the Power-Up self-
tests and diagnostics on the FM. Only qualified
personnel are permitted to work inside the main
electrical enclosure.
ON POWER-UP
A “c” is displayed on the CPU on-board LED
(located inside the main electrical enclosure)
while a Checksum test of the upper and lower
EPROM is performed. If a failure occurs, the LED
display will indicate the Fnnn error code as
described under the “User Initiated Self-Test”.
The control will not function if an error occurs.
USER INITIATED SELF-TEST
The self-test procedure will be activated if the
ABORT button (next to the LED) on the CPU board
is held down while the RESET button (next to the
batteries) is pressed, then released. At the begin-
ning of each test, the least significant digit of the
test number will be flashed on the LED display. At
the first failure, the letter “F” and the failed test
number will be rotated continuously on the LED
display. The decimal point will be flashed to sepa-
rate digits. To resume testing at the next test, the
ABORT button may be pressed. If all the tests are
completed without a failure, a “P” will be displayed
on the LED. If any of the tests fail and testing is
resumed, the LED will display an “F” when all tests
have been performed.
It will be necessary to RESET the control after run-
ning the self-test.
