15. Connect to external devices
This icon lights up when the connection mode is UART connection.
This function should be effective when connecting to the optional
interface converter.
The function of connecting to the external devices enables to switch
the relay contact output of the interface converter according to the
measured WBGT reading. The threshold of WBGT reading can be set
from level 1 to 4.
(Setting range of threshold level: 15.0 -
40.0°C)
WBGT reading will be monitored every minute immediately after
completing the setting when the function of connecting to the
external devices is enabled.
The relay contact of the interface converter is turned on when it is
confirmed that the measured value is more than the preset threshold.
If the threshold interval is narrow, the relay contacts may switch
continuously depending on the measured WBGT reading. It is
recommended to set the threshold value with enough margin.
* Refer to page 18 for the setting of the connection mode.
