Fault Code Fault Code Description Steps to resolve
3.2 EDMxx Fault
EDM contact(s) failed to close within 250 ms after the Safety Outputs turned Off:
• Check for a slow or stuck On contactor or relay
• Check for an open wire
3.3 EDMxx Fault
EDM contact(s) opened prior to turning On the Safety Outputs:
• Check for a stuck On contactor or relay
• Check for an open wire
3.4 EDMxx Fault
EDM contact pair mismatched for longer than 250 ms:
• Check for a slow or stuck On contactor or relay
• Check for an open wire
3.5 EDMxx Fault
• Check for an unstable signal on the input
3.6 EDMxx Fault
• Check for a short to ground
3.7 EDMxx Fault
• Check for a short between inputs
3.8 AVMxx Fault
After this Safety Output turned Off, an AVM input associated with this output did not close before
its AVM monitoring time expired:
• The AVM may be disconnected or its response to the Safety Output turning Off may
be too slow
• Check the AVM input and then perform a System Reset to clear the fault
3.9 Input Fault
The AVM input was open, but should have been closed, when the associated Safety Output was
commanded On:
• The AVM may be disconnected. Check the wiring to the AVM
3.10 Internal Fault Internal failure
— Contact BERNSTEIN AG (see
Repairs and Warranty Service on p. 191)
4.1 Supply Voltage Low
The supply voltage dropped below the rated voltage for longer than 6 ms:
• Check the power supply voltage and current rating
• Check for an overload on the outputs that might cause the power supply to limit
the current
4.2 Internal Fault
A configuration parameter has become corrupt. To fix the configuration:
• Replace the configuration by using a backup copy of the configuration
• Recreate the configuration using the Software and write it to the Safety Controller
4.3
– 4.12

Repairs and Warranty Service on p. 191)
4.13 Configuration Timeout
The Safety Controller was left in Configuration mode for more than one hour without receiving
any commands from the Software.
4.14 Configuration Unconfirmed
The configuration was not confirmed after being edited:
• Confirm configuration using the Software
4.15
– 4.19
Internal Fault Internal failure

Repairs and Warranty Service on p. 191)
4.20 Unassigned Terminal in Use
This terminal is not mapped to any device in the present configuration and should not be active:
• Check the wiring
4.21
– 4.34
Internal Fault Internal failure
— Contact BERNSTEIN AG (see
Repairs and Warranty Service on p. 191)
4.35 Overtemperature
An internal overtemperature condition has occurred. Verify that the ambient and output loading
conditions meet the specifications of the Safety Controller.
4.36
– 4.47
Internal Fault Internal failure
— Contact BERNSTEIN AG (see
Repairs and Warranty Service on p. 191)
4.48 Unused output A voltage was detected on an unconfirmed terminal.
4.49
– 4.59
Internal Fault Internal failure
— Contact BERNSTEIN AG (see
Repairs and Warranty Service on p. 191)
4.60 Output Fault An output terminal detected a short. Check output fault for details.
5.1
– 5.3
Internal Fault Internal failure
— Contact BERNSTEIN AG (see
Repairs and Warranty Service on p. 191)
6.xx Internal Fault
Invalid configuration data. Possible internal failure:
• Try writing a new configuration to the Safety Controller
10.xx Internal Fault Internal failure
