Transmitting the Alarm Signal
The alarm signal is transmitted from pin 14 (ALARM) of the remote control connector when
the LV 5380 internal temperature reaches or exceeds a specific value, when the fan is
broken, or when an error occurs in one of the items set to ON in the menu that appears
when you press F•4 ERROR CONFIG in the status menu.
The alarm signal is a 3.3-V LV-TTL level signal. You can set the alarm signal polarity by
setting ALARM POLARITY in the system settings.
You can set the channels whose errors are indicated by the alarm signal by setting ALARM
SELECT in the system settings.
