Problems and Possible Remedies
No communication between CyScan Dashboard and the Sensor
•
The Dashboard screen turns grey, the Primary Status Display reads “Communications
ERROR” and the Secondary reads “Unable to communicate with the sensor”. Click the
Disconnect button then the Connect button.
•
Check the power and client connections to the sensor.
•
Check that the unit is displaying the current time on the sensor information display. If it
is showing any errors then power cycle the sensor.
•
Check that the data feed converter is powered (yellow LED on) and that the outer
transmit/receive lights are flashing once every couple of seconds (i.e. the Dashboard is
trying to establish communications with the sensor unit). Under normal conditions the
outer LEDs should flash first followed by the inner two LEDs flashing in response (the
sensor unit answering with data).
Rotor does not rotate
•
Check the temperature of the unit is above -15°C degrees. Below this the rotor is
prevented from spinning to protect the sensor mechanics.
•
Check that the Dashboard is not showing a ‘Motor Stall’ alarm, if so suspend and then
resume the unit to restart the motor.
•
The sensor rotor might be prevented from rotating due to mechanical
blockage. Investigate and remove blockage.
•
Check the sensor information display on the system unit. Ensure that there are no
errors displayed. Otherwise power cycle the unit and observe the messages on the
display.
•
Check for ice build up under the rotor. Remove any ice which may be present.
System appears to be operational but no reflections are displayed within
CyScan Dashboard
•
Check that the dynamic and static blanking zones are configured correctly.
•
Clean the CyScan sensor window. (See
Cleaning the Sensor and Targets
on
page 48).
•
Check whether there are any reflections listed on the Reflections menu and that
the Zoom control on the main screen is set appropriately.
•
Check that the Tilt controls are set appropriately.
•
Check that the Power controls on the Reflections menu are set appropriately.
•
Check that the Range Filters on the Reflections menu are set appropriately.
System is operational but is not tracking
•
Check that the sensor has a clear view of the targets.
•
Check that the blanking zones are not blocking targets from view.
•
In the case of Multi-Target tracking, check that a suitable set of targets has been
selected (see
Selecting Targets for Multi-Target Tracking
on page 33).
System tracking but no data is received at the DP system
•
Check the DP Feed connection from the sensor.
•
Check that the DP Message Format matches the configuration of the vessel’s DP
system.
System operates correctly but in cold weather loses targets.
•
Check for condensation or ice on targets. Clean if necessary.
•
Check for condensation or ice on the window of the sensor. Clean if necessary.
