Failure messages - external
equipment, e.g.
Gyro Fail
Log Fail
GPS/EPFS Fail
Depth Fail
The gyro input has not been detected.
The log input has not been detected.
The GPS or EPFS input has not been
detected.
The depth sensor has not been
detected.
One or more of these messages may
appear in the alarm box of the screen
if the signals are missing. Note the
messages that are shown, as this
information will assist the service
engineer.
Check the reading on the associated
gyro unit. If a gyro repeater is fitted,
check that the repeater is on and
reading accurately.
Check the reading on the associated
log unit. If a log repeater is fitted,
check that the repeater is on and
reading accurately.
Check the position information from
the GPS/EPFS is accurate.
If the position sensing equipment is
provided with a switch to
enable/disable serially transmitted
data, check that the message type
GGA or GLL is enabled.
Check that the position sensor is set
to NMEA 0183.
Check the reading on the associated
echo sounder.
If an echo sounder repeater is fitted,
check that the repeater is on and is
reading accurately.
Call the Kelvin Hughes Service
Control Centre or the agent.
Poor discrimination in range
Sea anti-clutter control not set
correctly
Adjust SEA anti-clutter control
Tuning adjusted correctly, but poor
sensitivity
Dirt on antenna radiator face,
water in antenna or waveguide,
low magnetron,
receiver failure
Carry out a performance monitor
check. If the results shows
degradation there is probably a fault
in the transceiver.
If the performance monitor is OK,
clean the antenna radiator face. Refer
to the relevant ship's manual for the
transceiver for the procedure.
Target Tracking target not tracked
correctly
Poor definition of targets in sea
clutter
Adjust the SEA anti-clutter and RAIN
anti-clutter controls to improve target
definition.
