Fallback Arrangements
If the top priority sensor (for example EPFS1) cannot be used, this equipment auto-
matically uses the second priority sensor (for example, EPFS2) when multiple sensors
(EPFS1 and EPFS2 for example) are installed. When there is no fallback sensor avail-
able, each function is limited as follows:
Sensor
Heading
sensor
Speed
sensor
COG/SOG
sensor
Position
sensor
6-14
The [HDG] indication reads "***.*°"
The orientation mode is automatically set to [HEAD-UP].
TT, AIS, radar map and echo averaging are disabled.
When [LOG(WT)] is selected:
The sensor used is automatically switched in the following priority order:
EPFS(BT)
LOG(BT).
The SPD indication reads "***.* kn" when both EPFS(BT) and LOG(BT)
cannot be used.
When [LOG(BT)] is selected:
The sensor used is automatically switched in the following priority order:
EPFS(BT)
LOG(WT).
The SPD indication reads "***.* kn" when both EPFS(BT) and LOG(WT)
cannot be used.
When [EPFS(BT)] is selected:
The sensor used is automatically switched in the following priority order:
LOG(BT)
LOG(WT).
The SPD indication reads "***.* kn" when both LOG(BT) and LOG(WT)
cannot be used.
When the EPFS sensor cannot be used, the values of COG and SOG
are calculated from HDG and LOG(BT).
Additionally when the heading sensor cannot be used, the values of
SOG is calculated from LOG(BT). The COG indication reads "***.*°".
The POSN indication reads all asterisks.
AIS and radar map are disabled.
