is too high until the main drive will start. If the
Main Drive does start, set the Mode Select to
Setup and try to raise or lower the ram using the
Ram Up or Palmbutton Station. The ram should
relevel as it moves up or down.
LOW OIL LEVEL
If the oil drops below the minimum level, this
error message will be displayed and the main
drive will be shut down. Fill the hydraulic reser-
voir until the oil is centered in the sight glass.
OIL TEMP HIGH
This warning message will be displayed when the
temperature increases above the normal operat-
ing range. If the temperature continues to rise,
the main drive will be shut down and cannot be
restarted until the oil cools to an acceptable tem-
perature.
CHECK OIL FILTER
A sensor on the oil filter unit has indicated that
the oil filter must be replaced.
REDUNDANCY FAULT
The redundant interlock is monitored continu-
ously by the control. If the control detects a fault,
the main drive will be shut down. Check palm-
button and footswitch wiring. Check the wiring
and operation of relay 6CR.
EMERGENCY STOP !
This message will be displayed if any of the
EMERGENCY STOP buttons are pressed.
ACTIVE MEMORY CORRUPT!
The active memory (top stop, reversal position
etc.) is checked during the power-up sequence. If
the control detects that the active memory may be
corrupt, then it will be reset to all default values.
This error is normal after a software update, CPU
board replacement, RAM SIMM replacement, or
dead batteries.
CONFIG MEMORY CORRUPT!
CONFIG MEMORY ALTERED!
These two error messages indicate that the con-
trol has detected incorrect values in the configu-
ration memory. Some or all of the configuration
memory may have been reset to default values.
These errors are normal after a software update,
CPU board replacement, RAM SIMM replace-
ment, or dead batteries. If the “CONFIG MEMO-
RY ALTERED” error occurs on the Multi-Axis
Control after a software update, the message
may be cleared by the operator. In all other
cases, the error may only be cleared by entering
the service access code. This can only be done by
a CINCINNATI INCORPORATED Service Repre-
sentative, who will enter the proper configuration
values for the machine. It is very important that
the configuration values are correct to ensure
proper machine operation.
LIGHT GUARD DID NOT INTERRUPT
The light guard is tested at power-up and every
stroke of the press. If the light guard interrupt
test fails, machine operation during guarded por-
tions of the stroke will be disabled until the test
passes. Check all connections to the light guard.
Check the light guard for proper operation.
LOW BATTERY ON CPU BOARD
The control has detected a low battery condition
on the CPU board during the power-up sequence.
There are two lithium watch batteries on the CPU
board. Always replace them one at a time.
Do not
remove both batteries simultaneously, as all
memory will be lost. Failure to replace the bat-
teries could lead to a loss of all program files
and the machine configuration (which will
require a service call). This check is only per-
formed during the power-up sequence, so it is a
good idea to cycle the power at least once a
week to make sure the batteries are monitored.
CHECK INPUT BOARD #1
CHECK LC OUTPUT BOARD #1
(low current output board)
CHECK HC OUTPUT BOARD
(high current output board)
LEFT POT FAILURE
RIGHT POT FAILURE
The control has detected a failure in one of the lin-
ear transducers (POT) that measure ram position.
Check the POT, the cables, analog board and
power supply operation. This message may also be
displayed if the POT has reached its end of travel.
Normally the POTs operate with 0.75” (19mm) of
extra travel at each end.
LIGHT GUARD IS INTERRUPTED
If the light guard is interrupted while the guard is
enabled and the ram is moving, or a footswitch or
palmbutton is pressed while the guard is enabled
and interrupted, this message will be displayed.
This message is only a warning and is intended to
inform the operator that something is blocking
the light guard. There is no need to press the CLR
key – this message will self clear. If the beam is
not blocked and the message persists, check the
alignment and functioning of the light guard. To
continue the stroke, operator controls must be re-
initiated. Downward ram movement prior to
reaching Mute position will be stopped if the pres-
ence sensing device is interrupted. Presence
sensing is muted on the Up Stroke and below the
Mute position.
