Error type
Brief description
Cause
Troubleshooting
E2
Error in the safety laser
scanner
The safety laser scanner has an
internal error.
b
Perform a device restart using
the display or Safety Designer or
interrupt the voltage supply for at
least two seconds.
b
Replace the safety laser scanner
and send it to the manufacturer
for repair.
E3
Error in the system plug The system plug has an internal
error.
b
Perform a device restart using
the display or Safety Designer or
interrupt the voltage supply for at
least two seconds.
b
Replace the system plug.
E4
Incompatible system
plug
The system plug is unsuitable for
the safety laser scanner.
b
Check part number or type code.
b
Replace the system plug.
E5
Dazzle error
Strong external light source, e.g.,
sun, halogen headlamps, infrared
light source, stroboscope.
b
Remove or cover the light source.
b
Perform a device restart using
the display or Safety Designer or
interrupt the voltage supply for at
least two seconds.
L8
Error in the reset input
An invalid signal is applied at a reset
input. The reset signal is applied for
too long.
b
Check the reset pushbutton, the
wiring, and any other compo‐
nents affected.
M1
Incompatible configura‐
tion of the data output
The data output is configured in a
way that the device does not sup‐
port (e.g., invalid start angle).
b
Reconfigure the data output.
M2
Data output: Data
packets lost
The data output could not transmit
all data packets (e.g., buffer mem‐
ory full).
b
Configure the data output so that
less data is transmitted.
M3
Configuration not veri‐
fied
The configuration is not verified.
b
Verify the configuration.
N2
Incorrect switching
sequence
The configured switching sequence
was interrupted by the new monitor‐
ing case.
b
Check the machine’s work proc‐
ess.
b
Change the configured switching
sequence monitoring.
N3
Invalid input signal
The input signal for switching
between monitoring cases received
via the network is invalid. The invalid
signal is applied for longer than 1 s.
b
Check the control over the net‐
work.
N4
Incorrect activation of
the control inputs via
the network
The input signal for activating
switching between monitoring cases
received via the network is invalid.
The invalid signal is applied for lon‐
ger than 1 s.
b
Check the control over the net‐
work.
N5
Invalid input signal
The input signal for switching
between monitoring cases received
via the network is invalid. The invalid
signal is applied for longer than 1 s.
b
Check the control over the net‐
work.
N6
Invalid monitoring case
number
The monitoring case number
received via the network does not
match the configuration of the
device. The incorrect number is
applied for longer than 1 s.
b
Check the configuration with the
Safety Designer.
b
Check the control over the net‐
work.
R1
Connection errors
The data connection between the
control and device is interrupted.
b
Check the connection between
the device and control.
b
Adjust the data transmission rate
in the control if necessary.
