C2
Incompatible configura‐
tion
The configuration in the system plug
does not match the device’s func‐
tionality.
b
Check device variant.
b
Replace or reconfigure the
device.
C3
Incompatible firmware
The configuration in the system plug
does not match the device’s
firmware version.
b
Check the firmware version of
the device.
b
Replace or reconfigure the
device.
E1
Fault in the safety laser
scanner
The safety laser scanner has an
internal fault.
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.
E2
Fault in the system plug The system plug has an internal
fault.
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.
E3
Fault in the system plug The system plug has an internal
fault.
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.
F1
Current too high at an
OSSD
The current is too high at an OSSD.
The limit has been exceeded for cur‐
rent allowed short-term or perma‐
nently.
b
Check the connected switching
element.
F2
OSSD short-circuit to
24 V
There is a short-circuit to 24 V at an
OSSD.
b
Check the wiring.
F3
OSSD short-circuit to
0 V
There is a short-circuit to 0 V at an
OSSD.
b
Check the wiring.
F4
Short-circuit between 2
OSSDs
There is a short-circuit between 2
OSSDs.
b
Check the wiring.
F9
General OSSD fault
At least one OSSD is showing unex‐
pected behavior.
b
Check the wiring of the OSSDs.
L2
Invalid configuration of
the external device
monitoring (EDM)
The configuration of the external
device monitoring (EDM) is invalid.
The configuration is unsuitable for
the wiring.
b
Check whether the external
device monitoring is connected
correctly.
b
Use Safety Designer to check the
configuration.
L3
Fault in the external
device monitoring
(EDM)
A faulty signal is applied at the
external device monitoring (EDM).
The allowed tolerance time has
been exceeded.
b
Check whether the connectors
are wired correctly and operating
correctly.
L8
Fault 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.
L9
Short-circuit at the
reset input
Exactly the same signal is applied at
a reset input as at another input, an
OSSD or an output. There is possibly
a short-circuit.
b
Check the wiring for cross-cir‐
cuits.
