CHAPTER 5: DIAGNOSTICS
The DL2 is a Doppler speed log system with 4-6 PCBs (depending on option choices), a significant
amount of cabling, an acoustic sensor and a hull mounting. All of these elements can fail, and
SKIPPER has strived to make the system detect as many problems with these units as possible
automatically. If the system does show signs of measuring wrongly, do the following:
•
Recycle the power (The DL2 has no power switch, use power input switches)
•
Check the calibration
•
Check the self diagnostics
The diagnostics will test the following parameters:
•
NMEA outputs
• Communication to the sensor
•
Sensor Receiver functionality
•
Internal voltages
• Temperature
•
Other internal parameters
If it finds an error, . Press the SKIPPER Logo on the left of the test with error and check which
parameters are not approved. If this gives no help, contact SKIPPER service or your local dealer. A
full list of SKIPPER dealers is available on www.skipper.no.
This page allows diagnostic testing, a speed simulation (forcing the sensor to simulate a speed. an
alert simulation and some parameters adjustments), If the sensor is not attached, the source can be
changed to the JB70 electronic unit , or to an input GPS. When active an S will be shown on screen.
The diagnostics page is under continuous development and may change in software upgrades.
