SECTION 5—FAULT MESSAGES AND GENERAL MESSAGES
Fatal Fault Messages
Fatal fault messages can NOT be cleared. An e-stop is required for the press to recover. The problem should be fixed and then restored to the machine.
(Continued on next page.)

MESSAGE
DESCRIPTION/SOLUTION
BRAKE FAULT
The stopping time has exceeded the programmed limit for the brake fault setting.
When this message is displayed, acknowledge the message by pressing ENTER and
it will clear. No press action can be initiated during this time. Once it clears, continue
with normal operation. If faults persist, consult your supervisor, as the brake may need
inspection or adjustment to improve the stop time. See pages 46 - 48 for a detailed
description of the brake monitor.
SSR1 or SSR2 OFF FLT
One or both SSRs (solid-state relays) did not shut off and voltage was detected via the
redundant feedback circuit. Turn the module power switch off for 5 to 10 seconds.
Turn it back on and proceed as normal. If the message persists, the module may need
to be replaced. Consult factory.
SSR2 ON FLT
SSR2 (solid-state relay) did not turn on and voltage was not detected via the redundant
feedback circuit. Turn the module power switch off for 5 to 10 seconds. Turn it back
on and proceed as normal. If the message persists, the module may need to be
replaced. Consult factory.
SSR1 or K1 ON FLT
SSR1 (solid-state relay) and/or K1 safety relay did not turn on and voltage was not
detected via the redundant feedback circuit. Turn the module power switch off for 5
to 10 seconds. Turn it back on and proceed as normal. If the message persists, the
module may need to be replaced. Consult factory.
SSR1 or K1 OFF FLT
SSR1 (solid-state relay) and/or K1 safety relay, did not shut off and voltage was
detected via the redundant feedback circuit. Turn the module power switch off for 5
to 10 seconds. Turn it back on and proceed as normal. If the message persists, the
module may need to be replaced. Consult factory.
SSR2 OFF FLT
SSR2 (solid-state relay) did not shut off and voltage was detected via the redundant
feedback circuit. Turn the module power switch off for 5 to 10 seconds. Turn it back
on and proceed as normal. If the message persists, the module may need to be
replaced. Consult Factory.
MOTION REFERENCE FLT
The press cycle did not produce motion within the given reference time allotted.
Check that the press is running at full speed and the air pressure hasn’t dropped. If
this message persists, rerun the press setup from TDC and note the reference time
reported. Possible circuit failure; consult factory.
MOTION DROPPED FLT
The press cycle lost motion once it was sensed at the start of the cycle. Check that the
press is running at 4 SPM or greater. If this message persists, rerun the press setup
from TDC and note the reference time reported. Possible circuit failure; consult factory.
MOTION, NO RUN
The control detected motion prior to starting a press cycle. Check for correct wiring to
the resolver connection on the SSC-1500 control module. Verify the chain is on the
sprocket for the resolver and is tight. Check that the SPM display is 000 when the
crankshaft is at rest, or prior to starting a press cycle. Verify the resolver cable is not
run near high voltage lines (motor leads). Possible circuit failure; consult factory.
