9 Troubleshooting and Diagnosis Options
9.1 Optical displays
For assignment and position of the status LEDs see chapter "Bus status display,
series 75" on page 31.
9.1.1 Device Status, LED1 Bicolor

Cause
Remedy
OFF
Power supply absent
Check power supply, wiring
Hardware error,
measuring system defective
Replace measuring system
3x 5 Hz
repeating
−
Measuring system could not
synchronize with the F-Host in
the start-up phase and
requests an operator
acknowledgment
−
An error in the safety-oriented
communication or a
parameterization error was
detected, and has been
eliminated
For the operator acknowledgment of the measuring
system an acknowledgment about the safety
program at the corresponding variable is required
ON
Measuring system ready for
operation

red
Cause
Remedy
ON
A safety-relevant error was
detected, the measuring
system was put into fail-safe
status and is outputting its
passivated data:
In order to restart the measuring system after a
passivation the error must generally be
eliminated first of all and then the supply
voltage switched OFF/ON.
−
Error in the safety-oriented
communication
−
Try to localize the error with the aid of diagnosis
variables (dependent on the control unit)
−
Check that the set value for the
F_WD_Time
parameter is suitable for the automation task,
see chapter "F_WD_Time" on page 42
−
Check whether the PROFINET connection
between F-CPU and measuring system is faulty
−
The set value for the
Window
increments
parameter was
exceeded
−
Check that the set value for the
Window
increments
parameter is suitable for the
automation task, see chapter "Window
increments" on page 43
−
The permissible ambient
temperature range, as defined
under the corresponding
article number, was fallen
below or exceeded
−
Suitable measures must be taken to ensure that
the permissible ambient temperature range can
be observed at all times
−
The measuring system was
supplied with >36 V DC for
longer than 200 ms
−
The measuring system must be shut down
immediately and checked in the factory. When
sending the measuring system to the factory, the
reasons and circumstances relating to the
overvoltage must be specified
−
The internally calculated
PROFIsafe telegram is
defective
−
Power supply OFF/ON. If the error persists after
this measure, the measuring system must be
replaced
−
Scanning system, double
magnetic: the electrically
permitted speed which is
defined in the safety manual
was exceeded
−
Bring speed into the permissible range. Error-
acknowledgement about power supply OFF/ON.
