Error: laser shutter
The CLV has diagnosed a
system error. The "Device
Ready" LED does not light up
or it extinguishes. The CLV
restarts the system.
Device fault
If this system error occurs again
after the CLV is restarted:
Contact the SICK Service
department.
"EEPROM Check fault,
default parameters loaded"
The CLV has diagnosed an
irregularity in the EEPROM
and downloads the entire
default settings to the RAM
instead of the permanently
stored application-specific
parameters.
Device fault
Contact the SICK Service
department.
"EEPROM - reading fault"
The CLV cannot download the
application-specific parame-
ters, permanently stored in
the EEPROM, to the RAM.
Device fault
Contact the SICK Service
department.
"EEPROM - writing fault"
The CLV cannot write the
current parameters in the
RAM to the EEPROM.
Device fault
Contact the SICK Service
department.
"Host – receive fault"
The host has requested the
data output string last sent by
the CLV three times; NAK has
been issued with each
attempt.
•
Host receive set incorrectly
•
Data transmission interrupted
e.g. by cable break
•
Check host.
•
Check connecting cables and
monitor data transmission at
the host interface. To do so,
upload from the CLV using the
CLV Setup program, choose
the A
UXILIARY
I
NTERFACE
tab and
select M
ONITOR
H
OST
I
NTERFACE
from the drop-down list.
Download to the CLV! Start the
Terminal Emulator.
"Host – transfer too slow"
In the CLV, data is available
for output faster than it is
transmitted to the host.
•
Baud rate too low
•
Incorrect protocol type
selected
•
Protocol timeout too long for
the reading pulse frequency
Check the configuration of the
host interface.
