5 NX2 FAULTFINDING AND TESTS ON BOARD
The Silva NX2 System can easily be tested on board a vessel. Always start by
confirming that the “Maintenance and fault finding” in the Operation Manuals has
been checked by the customer. Also be convinced that all system and calibration
settings are not causing the problems.
5.1 BLANC DISPLAY - POWER TEST
Check connection terminal at the back of the Instrument: Green(+) to Screen(-) you
should have 12 Volt (10-16 V), if not: check wires, fuse and battery. If the
Instrument do not run the starting up procedure in spit of 12V OK power, it has to be
replaced and sent to Silva for further tests.
5.2 NO OR WRONG VALUE ON NX2 INSTRUMENTS
Al transducer inputs on the NX2 Server are equipped with signal sensors indicating
incoming signals by blinking LED’s.
Log transducer will shift the LED on log input from on to off and vice versa for every
half turn on the impeller.
Depth LED will blink on every received Echo.
Compass LED’s will blink on each channel receiving signal, with constant frequency.
Wind LED’s will blink on each channel receiving signal, with a frequency related to
the actual wind speed.
If lack of signal indication on LED’s, check wires, connections and transducer.
