2 Alarms
2.1 General
The diagnostics of errors are given by the issued alarms. The troubleshooting is based
on the proposed fault tracing and corrective actions given in the alarm descriptions.
The first part of the alarm describes which thruster it concerns, example PORT MP NC
(port main propeller normal control).
Equally it exists alarms for STBD MP NC, BOW1 NC, STERN1 NC etc.
All these alarms will be shown on the alarm page on the touch screens.
Alarms from the mechanical part of the thruster and the optional frequency converter
also appears on the the alarm page. For more information about these alarms see the
manual for the trusters mechanical parts or the manual for the frequency converter.
Every alarm in the alarm list (1) appears with red text. These alarms will flash red until
the Ack button (3) is pressed or the problem ceases to exist. An alarm that has been
acknowledged will remain red until problem ceases to exist and then disappear. An
unacknowledged alarm will turn blue when the problem ceases to exist, remain blue
until it has been acknowledged and then disappear.
See chapter 12 Design Drawings for wiring diagrams for the Helicon X3 system and
