Error Messages
Two types of errors may be displayed:
Programming Programming error messages indicate that a programming attempt was invalid. Except for error message
“E0 EErr”, the control will continue to operate the outputs normally during programming errors.
Programming error messages will be flagged in the following list with this symbol:
System System errors occur when conditions are detected that can cause unreliable operation. All outputs will
be disabled when system error messages occur. The cause of a system error must be determined
and corrected before reliable controller operation can be guaranteed. Contact the Electro Cam factory
for assistance whenever system error messages repeat. System errors will be flagged in the following
list with this symbol:
CrASH Watchdog Timer Fault
The Watchdog Timer has timed out, indicating that the controller is not properly executing its program.
All outputs will be disabled during this error condition. This problem can be caused by severe electrical
noise or hardware failure within the control.
Solution: Remove and restore AC input power to the controller. If the control immediately repeats the
CrASH error condition each time it is powered up, hardware within the control is damaged. Call Electro
Cam for return authorization and further advice.
If CrASH errors occur at intermittent intervals, they are apparently being caused by excessive electrical
noise. Check wiring for proper shielding and grounding.
E0EErr EEPROM Programming Error
The Checksum associated with the Function programming (controller’s global configuration) was found
to be incorrect.
Solution: Press the CLR/CLE key to clear the flashing error message. All configuration programming
(Functions) will be returned to the factory defaults, but setpoint information will remain unchanged. It will
be necessary to re-program all functions that were altered from the factory defaults. (See page A-16, Alt
Fcn 7000 for a listing of factory defaults.)
E0FAtL Memory Fault
A problem with random access memory has been detected and the unit cannot function properly. Memory
circuitry in the controller is not functioning properly.
Solution: Control must be returned to factory for repair. Call Electro Cam first for return authorization
and further information.
E1 CHEC Checksum Error (Checked on Power-up)
The stored checksum value did not match the memory contents when checked on power-up. This
problem can be caused by severe electrical noise during power-up or hardware failure within the control.
Solution: Remove and restore AC input power to the controller. If the control immediately repeats the
E1 CHEC error condition each time it is powered up, hardware within the control is damaged. Call
Electro Cam for further information.
E1 OLAP Pulse Overlap
The output pulse that was just created or adjusted overlaps or touches another pulse that already exists
in the same output channel. It was therefore not entered. Also, if one edge of a pulse is moved until it is
equal to the other edge, an “E1 OLAP” error will occur.
Solution: Press the CLR/CLE key to clear the flashing error message. Use VIEW keys to review the
setpoints that are already programmed on this channel to determine the cause of the overlap condition.
E2run Item Can Not be Programmed While Running
While the encoder/resolver was turning, an attempt was made to change a programmed item that cannot
be changed unless the transducer is stationary. Items which cannot be changed while in motion are:
Direction of Rotation (FCN 0 - CL/CCL), Scale Factor (FCN 0 - SF), Output Grouping (FCN 8), and
Enable Inputs and Modes (FCN 9).
Solution: Press the CLR/CLE key to clear the flashing error message. Stop the machine (transducer)
while making the program change.
