SICK nanoScan3

Error type Brief description Cause Troubleshooting
E5 Dazzle error Strong external light source, e.g.,
sun, halo
gen headlamps, infrared
light source, stroboscope.
►
R
emove or cover the light source.
►
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
in
put. The reset signal is applied for
too long.
►
Chec
k the reset pushbutton, the
wiring, and any other compo‐
nents affected.
M1 Incompatible configura‐
t
ion of the data output
The data output is configured in a
way that the device does not sup‐
port (e.g., invalid start angle).
►
R
econfigure the data output.
M2 Data output: Data
pac
kets lost
The data output could not transmit
all data packets (for example, buffer
memory full).
►
C
onfigure the data output so that
less data is transmitted.
M3 Configuration not veri‐
f
ied
The configuration is not verified.
►
V
erify the configuration.
N1 Invalid input signal The signal applied at the control
in
puts is not assigned to a monitor‐
ing case. The signal is applied for
longer than the set input delay +1s.
►
Chec
k the configuration with
Safety Designer.
►
Check the working process of the
machine.
N2 Incorrect switching
seq
uence
The configured switching sequence
was interrupted by the new monitor‐
ing case.
►
Chec
k the working process of the
machine.
►
Change configured switching
order.
N3 Invalid input signal The input signal for switching
be
tween monitoring cases received
via the network is invalid. The invalid
signal is applied for longer than 1s.
►
Chec
k the control over the net‐
work.
N4 Incorrect activation of
t
he 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.
►
Chec
k the control over the net‐
work.
N5 Invalid input signal The input signal for switching
be
tween monitoring cases received
via the network is invalid. The invalid
signal is applied for longer than 1s.
►
Chec
k the control over the net‐
work.
N6 Invalid monitoring case
number
The monitoring case number
r
eceived via the network does not
match the configuration of the
device. The incorrect number is
applied for longer than 1s.
►
Chec
k the configuration with
Safety Designer.
►
Check the control over the net‐
work.
R1 Connection error The data connection between the
c
ontroller and device is interrupted.
►
Chec
k the connection between
the device and controller.
►
Adjust the data transmission rate
in the controller if necessary.
T1 Temperature error The operating temperature of the
s
afety laser scanner has exceeded
or fallen below the permitted range.
►
Chec
k whether the safety laser
scanner is being operated in
accordance with the permissible
ambient conditions.
W1 Warnings exceed toler‐
ance t
ime
The combination of multiple warn‐
ings has resulted in an error. The
tolerance time of 1s has been
exceeded as there are multiple
warnings.
►
Use S
afety Designer to check
what warnings exist.
