11.2 Display
11.2.1 Error stack entries
Up to 20 status and error messages are stored in the unit and can be called up via the dis-
play (see section entitled "Display Menu – Configuration – Menu Overview"). They can also
be called up if the error has been recovered and the unit has been restarted.
The following information is shown on the display:
} Sequential number of an error stack entry (1 ... 20).
} Error number (0 ... 65 535)
} Error category
– User-recoverable errors
are described in the following list
Remedyrecover error; if necessary contact Pilz
– Internal errors (system errors, all errors that are not described in the list)
Remedy: switch device on and off, contact Pilz
} System time
} Additional information for support
– Error source (GG A/ GG B/ EM A/ EM B)
– Error parameters 1 ... 4
Please note:
In many cases, one error can lead to subsequent errors. For this reason, start troubleshoot-
ing with the first error that occurred.
If recoverable errors and internal errors have been entered at the same system time, in-
ternal errors can be ignored because in this case, the causes of the error are always recov-
erable errors.
11.2.2 Current error messages
If an error is detected, the "Fault" LED lights up on the device and an error message ap-
pears on the display (see error stack).
Up to 8 current error messages are shown on the display.
A message is shown until the error is recovered and the device has been switched off and
then on again, the software is restarted or an error acknowledgement has been carried out.
Errors can be acknowledged via the select inputs, by configuring the special function "Error
acknowledgement". User-recoverable errors can be acknowledged via this function; the fol-
lowing errors are an exception:
Error numbers 2, 4, 5 as these are purely informative.
Error number 2000, as this is acknowledged automatically during recovery.
Error numbers 3, 5003, 10268 and 10269.
All errors with a number ≥ 30000
