Diagnostics alarm
Short-circuit to ground
Invalid/inconsistent firmware
present
Channel failure acknowl-
edgment
F-address memory not ac-
cessible
Frequency too high
Undertemperature
Supply voltage too high
Supply voltage too low
Supply voltage outside the nominal range
If the supply voltage L+ is outside the specified value range, the DIAG LED flashes and the
module is passivated.
When the voltage is then recovered (level must remain within the specified value for at least
1 minute (see Technical specifications (Page 47) Voltages, Currents, Potentials)), the DIAG
LED stops flashing. The module remains passivated.

Fault Meaning
code
262 Short-circuit to ground can mean:
D
The output cable is short-circuited to
•
ground.
The output signal is short-circuited to
•
ground.
The capacitive load is too high.
•
You must eliminate the error within 100
hours; otherwise, the F-module is perma-
nently passivated and an acknowledg-
ment is no longer possible.
283 The firmware is incomplete and/or firm-
D
ware added to the F-module is incompat-
ible. This leads to errors or functional
limitations when operating the F-module.
779 A channel fault was detected. Confirma-
D
tion is required to enable the channel.
781 The F-source address and F-destination
D
address stored in the coding element
cannot be accessed.
785 The maximum switching frequency of the
D
F-module has been exceeded.
786 The minimum permissible temperature
D
limit has been violated.
801 The supply voltage is too high.
D
802 The supply voltage is too low.

Solution
Correct the process wiring.
•
Increase the test times (dark, light).
•
Check the actuator.
•
Perform a firmware update for all
•
parts of the F-module and note any
error messages.
Use only firmware versions re-
•
leased for this F-module.
Confirm the channel fault.
Verify that the coding element is pre-
sent or replace the coding element.
Reduce the switching frequency (see
Technical specifications (Page 47))
Operate the F-module within the speci-
fied temperature range (see Technical
specifications (Page 47))
Once the temperature has increased
and returns to the specified range, the
F-module must be removed and in-
serted or the power switched OFF and
ON.
Check the supply voltage.
Check the supply voltage.
