8.3.1 CLV without external parameter memory

Message Meaning Possible cause Remedy

"CLV SYS-Failure: xxx"

The CLV has diagnosed a

system error.

The "Device Ready" LED does

not light up or extinguishes.

The system is restarted.

Error key:

)

011 Data error (RAM)

012 Address error (RAM)

013 RAM to small

051 Speed out of tolerance

(mirror wheel)

061 Mirror interval out of

tolerance

071 Error: laser shutter

091...095 Error: focus control

101...118 Error: external parame-

ter memory

130 Amplifier error

131 Background profile

invalid

132 Center position CP 50

implausible

133 Brightness overflow

201...215 DSP error

If the error occurs again after the

CLV is restarted, contact the SICK

Service department.

1) Deactivate the CAN interface

to suppress error numbers above

300 (not relevant in stand-alone

mode). To do so, upload the

parameter set from the CLV using

CLV-Setup, choose the CAN

NTERFACE

tab and deactivate the

function in the CAN I

NTERFACE

UNCTION

section.

Download the parameter set to

the CLV!

"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 load the appli-

cation-specific parameters, per-

manently stored in the EEPROM,

into 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.

"Focus table inconsistent:

defaults loaded"

The CLV has diagnosed an

irregularity in the internal refer-

ence table for the focus posi-

tions selected by the user. It

therefore loads the default set-

ting of the distance configura-

tions.

Device fault. Contact the SICK Service

department.
