Display
Possible cause
Remedy
Waiting for configuration
or configuration not
completed
b
The display goes out automatically once the
configuration has been successfully trans‐
ferred.
If the
display does not go out:
b
Check the system configuration using the
CDS. Transfer the corrected configuration to
the device again.
b
Check whether the configuration saved in the
system plug is compatible with the safety laser
scanner.
Waiting for restart of the
device
b
Switch off the voltage supply for the safety
laser scanner for at least 2 seconds and then
switch it back on.
or
Fault in the external
device monitoring (EDM)
b
Check whether the contactors are working cor‐
rectly or have been wired incorrectly and rec‐
tify any error.
b
Additionally if
is displayed: Switch off the
device, wait at least 3 seconds, then switch
the voltage supply back on.
Error in the control
switch for restart or
reset
b
Check the functionality of the control switch.
The pushbutton may be defective or stuck.
b
Check the wiring of the control switch for
short-circuit to 24 V.
Speed tolerance
exceeded: The differ‐
ence between the
speeds measured by the
incremental encoders is
too large.
b
Check the incremental encoders.
b
Check the configuration of the incremental
encoder inputs using the CDS.
Direction of movement
output by the incremen‐
tal encoders is different
b
Check the wiring of the incremental encoder
inputs, e.g., for incorrect pin assignments.
Maximum frequency at
INC1 input exceeded
b
Check the function of the incremental
encoders.
b
Check the configuration of the incremental
encoder inputs using the CDS.
b
Check whether the maximum allowed speed
of the vehicle is exceeded.
Maximum frequency at
INC2 input exceeded
or
The monitored speed
threshold has been
exceeded.
b
Check the function of the incremental
encoders.
b
Check the configuration of the incremental
encoder inputs using the CDS.
b
Check whether the maximum allowed speed
of the vehicle is exceeded.
b
Check the speed threshold configured in the
related monitoring cases.
Sensor head faulty
b
Switch off the voltage supply for the device for
at least 2 seconds and then switch it back on.
If the display does not go out:
b
Send the sensor head, I/O module or system
plug to the manufacturer for repair.
I/O module faulty
Configuration memory in
the system plug defec‐
tive
A second device which
is connected via EFI is in
the fault state.
b
Check the connected device and the connec‐
tion.
