6-6-4. Contents and countermeasures of the error messages
The control terminal will display eleven types of error messages according to the error content.
However, depending on the model, some are not used because of no detection, or some part of the
message may differ. For details of the messages and their countermeasures, refer to operation manuals
provided with each model.
Standard error messages and their countermeasures are as follows.
Content : Faulty crosspoint hardware
As a result of comparing the presence/absence of the crosspoint signal in the station
being displayed, this message will be displayed if the input signal was found to be
present without the output signal, and vice versa, or if the input/output board has not
been inserted correctly.
Countermeasure : The crosspoint of station * * * is faulty. Check the input/output board has been
properly installed.
Content : This message is displayed when the temperature inside of the station being displayed
has risen, or when the fan has stopped.
Countermeasure : Promptly turn off the power supply of station * * *, and check for short-circuits,
power leakage, faults of the mechanical parts surrounding the fan, etc.
Content : This message is displayed when the SYNC/ASYNC select switch on the CPU board of
the switcher has been set to the sync switching mode (SYNC), and the reference video
signal has not been input to the REF IN connector.
Countermeasure : Connect the sync signal to the REF IN connector of station * * *.
n
Set the SYNC/ASYNC select switch to “ASYNC” if the reference signal is not present. When the
reference signal is not input in the sync switching mode (SYNC), the crosspoint is switched automatically
as the async switching mode (ASYNC).
Content : This message is displayed when the power supply output during operations has
dropped and it is changed over to the backup power supply.
Countermeasure : Remove the faulty power supply of station * * *, and repair or replace it with a new
one.
