14-seconds signal
(function CLr)
This function is used to delete critical error messages.
For an overview of possible error messages, see page 29.
After the end of the control signal, the internal micro-electronics
carries out a self-test. If the internal check is successful, the output
signal changes from a LOW level to a HIGH level. This clears the
error and the device is ready for operation. If the internal check is
unsuccessful, the device continues to transmit the LOW level as
an output signal. In this case, further troubleshooting steps must be
taken, see page 29.
Output signals at PIN 4
The possible output signals that may be present at PIN 4 are
described in,
Figure 17
to
Figure 19
, page 28.
These signals can be used for diagnosis of the operating status.
