An alarm is acknowledged by pressing the ACK/ENT button.
- The audible alarm will be silenced.
- If the alarm situation has disappeared, the alarm lamp will be
switched off, and the alarm code will be removed from the LCD.
- If the alarm situation continues, the alarm lamp will switch from
flashing to steady light. The LCD will return to show true bearing
with flashing numbers to indicate that the bearing may have large
errors.
An alarm code for an active error may be recalled by pressing the DISP
button until the alarm display is shown. It is possible to recall any alarm
code in the LCD for as long as the alarm situation is present.
When an alarm is generated and not removed by pressing the ACK/ENT
button, further actions should be taken to correct the alarm situation.
The following pages present an overview of symptoms and corrective
actions for errors that may be corrected by the operator. If none of these
procedures correct the problem, contact the local Simrad dealer for advice
or to request on-board service.
Before any fault-finding procedure is started, the following actions should
be performed to verify a system error:
1
Shut down and restart the Gyro compass.
2
Verify that all cables are properly connected according to the
wiring diagrams, page 84 onwards.
