Failure state

The device is in the safe state following an inter-

nally diagnosed device error.

Possible causes are:

–Operating temperature over or underrange

Remedy: check the ambient conditions

(e.g., sufficient ventilation in the control

cabinet) and operate the safe PROFINET

gateway within the range specified.

– Temporary EMI above the permissible

compatibility limits.

Remedy: check ambient conditions (e.g.,

equipotential bonding and grounding

concept). Detect and remove sources of

interference.

This operating state can only be exited by

switching the supply voltage of the safe

PROFINET gateway off and on again (power up).

If a power up does not solve the problem, please

contact Phoenix Contact.

Flashing

The safety-related function of the safe

PROFINET gateway is incorrect, incomplete or

not even parameterized.

OFF

Operating state; the device is parameterized, no

errors present.
