SECTION 5—FATAL AND GENERAL FAULT MESSAGES
SSC-1500 Gen II Part-Revolution Solid-State Control

MESSAGE
DESCRIPTION/SOLUTION
PAIRED WITH INPUT #4
An attempt was made to program User Input 5, but it is paired with User Input 4. This message is displayed for 2 sec-
onds and then clears automatically. To unpair the inputs, the logic for Input 4 must be changed to N.O. (normally open),
N.C. (normally closed), or OFF (disabled). See pages 46–49 for information on programming the user inputs.
PROG ON
An attempt was made to switch to program on while the machine was running.
STM TEST FAILED
he palm buttons were released early during the STM test. Refer to pages 50-51 and retry.
REFERENCE FAILED!
PALM BUTTONS WERE
RELEASED EARLY
PRESS ECS TO EXIT
The resolver did not detect motion within 1.5 seconds during the reference cycle. Check that the resolver is wired cor-
rectly, and run the reference cycle again. Possible circuit failure; consult the factory.
REFERENCE FAILED!
SYNCE SWITCH WAS NOT
DETECTED
PRESS ESC TO EXIT
The sync switch in the resolver housing did not come on during the reference cycle. The sync switch can only come on
between 30° and 330°. The ideal location is around 90° for most press brakes. Check the wiring for the resolver and
check the LED on the control module for the sync switch input to ensure it is functioning. Ensure the machine is at TDC
when doing the reference cycle. If needed, remove the chain or coupling from the resolver drive and rotate until the
sync switch signal is not over top, and falls within 30° and 330°. Run a reference cycle again. Possible circuit failure;
consult the factory.
REFERENCE FAILED!
SYNC SWITCH CANNOT BE ON
WHEN STARTING
PRESS ESC TO EXIT
Reposition the resolver so the sync switch in the resolver housing is not on at the top of the stroke. Make sure the
resolver shaft keyway is perpendicular to the base at TDC.
STROKE COUNT EXPIRED
The stroke count has reached the programmed preset value and the press is now stopped. To clear the message and
reset the counter, press ENTER on the keypad. See pages 53-54 for information on programming the stroke preset.
SWITCH TO HAND
When performing a reference cycle or STM test, hand is the only means of actuation. Switch the actuating means
selector to HAND and continue.
