The least significant four bits
display information on the
affected reference voltage
source.
Range of values:
0 – Internal ref voltage source 1
1 – Internal ref voltage source 2
2 – Internal ref voltage source 3
Hardware test error
detected regarding a
reference voltage
source. All outputs are
maintained in a safe
state.
The test error could indicate a hardware error at
one of the three reference voltage sources in the
outputs. As a result, until error acknowledgement
all outputs are also returned to a safe state via the
general shutdown paths. The error is displayed on
the device by the red illuminated output LEDs.
An acknowledgement of this diagnostic message,
provided there are no other relevant error
messages present, deletes the message, cancels
the red LEDs and restarts the outputs.

The least significant four bits
display information on the
affected output.
Range of values:
0: M (High side switch)
1: Zone Z1 (High side switch)
2: Zone Z2 (High side switch)
3: Zone Z3 (High side switch)
8: M (Low side switch)
9: Zone Z1, Z2, Z3 (Common low
side switch)
Hardware test error
detected regarding the
mutual interlocking of
the outputs.
During the test an error was detected by briefly
switching off via the mutual interlocking of both
channels. The test error could indicate a hardware
error regarding the mutual switching off capacity of
the channels or a cross-circuit between outputs or
between the output and external signal. As a result,
until error acknowledgement all outputs are also
returned to a safe state via the general shutdown
paths. The error is displayed on the device by the
red illuminated output LEDs.
An acknowledgement of this diagnostic message,
provided there are no other relevant error
messages present, deletes the message, cancels
the red LEDs and restarts the outputs.

The least significant four bits

Implausible signal in
the feedback
monitoring of the local
outputs via the local
inputs.
The error is displayed by the red illuminated LED
for the affected output on the device. An
acknowledgement of this diagnostic message is
possible. The acknowledgement deletes the
message and enables a restart of the affected
output.

The least significant four bits
display information on the
affected output.
Range of values:
1: Zone Z1
2: Zone Z2
3: Zone Z3
An error was detected
when controlling the
relevant valves (non-
safe outputs).
The error could indicate a hardware error regarding
the activation of the non-safe outputs using SPI
communication. The local display is executed by
the red illuminated LED for the affected output on
the device. An acknowledgement of this diagnostic
message is possible. The acknowledgement
deletes the message and enables a restart of the
affected output.
