Diagnostics via Status Output Z1
Overview
The pulsed output Z1 provides diagnostics information in the form of a bit pattern.
Refer to the chapter Electrical Installation
(see page 55)
for additional information on wiring the Z1.
Diagnostics Codes
The device encodes diagnostics information into sequences of 10 bits with a total of 2 s (each bit
200 ms).
The first four bits (0010) represent the beginning of a bit sequence. The next six bits contain the
diagnostics code itself.
The following table lists the bit sequences of the diagnostics codes, the description of the
corresponding status as well as correctives, if applicable.
WARNING
INCORRECT USE OF OUTPUT
Do not use the additional output Z1 for safety-related purposes.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Bit sequence Description Correctives
Type
(1)
0010101101 Supply voltage out of
tolerance.
Verify correct wiring.
Use a suitable power supply.
E
0010000011 General error detected. Verify correct wiring.
Perform a power cycle.
If the error persists, replace the device.
E
0010000110 General error detected in
expansion module.
Verify correct wiring.
Perform a power cycle of the base safety module and the
connected extension module.
If the error persists, replace the extension module.
E
0010000111 Configuration error
detected. The position of
at least one of the
selectors has been
modified during
operation.
Verify that the position of the selectors is appropriate for
the application to be implemented.
Perform a power cycle.
If the error persists, replace the device.
E
(1) Type of message: E = Error detected, A = Alert, S = Status information
