Error message
Execution process
Cause of error
Recording error
Upon startup, the system verifies
itself. Logger card. If logger option
is activated.
1- Logger card is not installed,
2- Connector has defective
soldering or is broken,
3- There is a problem with the
logger card.
Limit memory
error
When starting system, there is a
verification (Writing/Reading) of the
backup chip of the limit
programmed (limiter scope).
1- There is a problem with flash
memory (U52)
Load chart
error
Upon startup, the system does a
read verification of load chart flash
memory chip.
1- Load chart chip is not
installed,
2- Verify the kind of memory it
must be a flash memory,
3- There is a problem with flash
memory (U12).
“C” memory
error
Upon startup, the system does a
read/write verification of bank C
EEPROM chip. It is used as a
backup for the system’s operation
parameters. Ex. winch, number of
strands, # duty.
1- There is a problem with
EEPROM memory (U45)
Clock error
Logger option must be activated.
System regularly verifies if seconds
are moving. If time does not
change then there is a problem.
1- Verify if black plastic cap is
installed on logger card
(contains battery crystal),
2- There is a problem with the
logger card.
“A” memory
error
Upon startup, the system does a
read verification of bank A
EEPROM chip. It is used as a
backup for calibration data.
1- There is a problem with
memory EEPROM (U44)
RAM memory
error
Upon startup, the system does a
read/write verification of RAM chip.
This is a volatile memory.
1- There is a problem with RAM
memory (U3). With Logger
option, the cause is RAM
memory (U5).
- if system is behaving
strangely,
- if system initializes often
during operation mode,
- if system never starts.
Not calibrated
There is no calibration for selected
duty.
1- Unloaded hoist calibration
(empty) and unloaded
deflection must be done.
