Installation DL2 Doppler Speed Log System
sysTem diagnOsTics
The Diagnostics screen allows the user to test the system, activating alarms and outputing set
speeds. It is also possible to perform self test of the system and check the status.
Self test will perform the following actions:
• Check internal voltages and compare them to defaults and installation references.
• Check connectivity and connected items.
• Disconnect NMEA ports and loop back to check circuit function.
• Measure function of the sensor (pinging between channels and analyse returning signals).
To test other systems connected to this system, a data test is available, allowing output parameters
to be entered and given out on all the activated outputs. In addition, an alarm condition can be
simulated and acknowledged. For demonstration, a simulator can be activated to show a recorded
data set over time. This function will turn off automatically after 6 hours or on power reset.
Speed simulation is a full check of the system. The speed information is set to the sensor and the
sensor produces frequencies corresponding to the desired speed. In this way all parts of the system
are in use, and this in itself is a good diagnostic check.
available OpTiOns in The diagnOsTic page
• Simulators
• Speed
In this page it is possible to set a xed speed and send this to the sensor. This will result in the
speed being presented on all displays and outputs. This mode is a full simulator and will verify that
all electronics and processing in the system are operational. When active an orange ‘S’ will show
on screen.
• Alarm
By pressing the alarm simulator a typical alarm will become active. this can be acknowledged as
normal, and will disapear when the simulator is removed.
errOr messages
The following error cases are accounted for.
