Latching and Self-clearing Alarms
Depending upon how your EMS-D10 was set up, some of the sensors’ alarms may be set to be latching, while others
may be self-clearing. The distinction is described below. See the EMS-D10 Installation Guide for more information on
configuring this setting for each alarm.
LATCHING ALARMS
If an alarm occurs on a sensor configured to be latching, the alert displays on screen until the ACK button is pressed,
even if the alarm condition goes away. This means if, for example, your oil pressure momentarily gets too high but
returns to normal, the instrument continues to alarm on the condition until that alarm is acknowledged. Latching alarms
let you to know if an alarm happened momentarily, when you might have otherwise missed it.
SELF-CLEARING ALARMS
If an alarm occurs on a sensor configured to be self-clearing, the alert displays on screen until either the ACK button is
pressed or the alarm condition goes away. Consider the example where you have configured your fuel pressure alarm to
be self-clearing. If your engine’s fuel pressure momentarily rises too high but then returns to normal, the EMS-D10
alarms for that brief instant, but stops as soon as the alarming condition has ceased; no acknowledgement is needed.
DSAB Alerts
When multiple Dynon Avionics instruments are networked together via DSAB, there are a few error messages
designed to warn you of failures or reduced functionality.
NETWORK CONFIGURATION ERROR: This error can only occur within a short period of time after the system is
turned on. This error indicates that a unit that was expected to be on the DSAB network was not found. For example, if –
in a system consisting of a FlightDEK-D180, EFIS-D100, and an HS34 – all three units are not present, this error
appears. This error is displayed when any part of the system is not working, including backup EDCs or OATs.
