Each electrical installation is instructed to be completed by the Pre Set up Procedure. We
recommend to double check these points before supplying power to the unit:
Remove any possible particles from the cabinet(s)
Carry out a visual inspection of the installed components and cables referring to
the layouts of the unit and to the interconnection drawings
Check that cable terminations have a firm grip of the cable wires
Check that cable glands have a firm grip around the cables
Check that the Transducer cable shield is firmly grounded in the cable gland of
the ELC.
Check for proper cable bends to assure a proper amount of slack
Check that ground connections are duly tightened.
Carefully check the main power voltage and the integrity of the fuses.
Also check that the transducer is correctly installed down in working position and
longitudinally aligned.
Set the SAL R1a Speed log to power, follow the procedure below and act accordingly. If
a fault occurs or is detected, use the Trouble-Shooting Guide to analyse and eliminate the
reason.
Check that the default settings, (LED 2) on the WTU-Assy board is turned on.
Check that the red Alert LED on the WTU-Assy board is turned off.
Use the Speed Log Master Display, SD4-3 to communicate with the WTU-Assy
by going into the R0 REMOTE DEV menu.
Go to Menu T0
Change to WRITE ACCESS ON
Move down to T1 and use default speed 8 knots or use speed as desired
NOTE: Now the SAL R1a will stop measuring ship’s speed and instead it is showing
the simulated speed on all users connected.
Check that all connected users show the same speed.
Change to and check at least two more speeds within the ship’s speed range,
including one speed astern (minus).
Enable menu T2 – noise test, using sub menu T2.1 and read the two values.
Both displayed values shall preferably be below 700 over time (values will vary).
Higher values may degrade the measuring performance of the log.
Enable menu T3 – signal balance, using sub menu T3.1 and read the value.
The readings shall be in the interval 50% – 200% and state OK, but if the ship is
not moving the values may vary a lot over time and be outside the allowed
interval during short periods. Check the reading for a couple of minutes before
any conclusions are drawn. A faulty TRU will seldom hit the correct interval.
Enable menu T4 – loop test, using sub menu T4.1 and read the three values.
First and last value shall be below 2, middle value in the interval 40 to 120.
Move to T6 menu and simulate Log Failure Alarm.
Check that connected alarm is activated (if any).
Leave the T menu by pressing Menu and Enter simultaneously two times.
Check that simulated speed has been replaced by actual speed.
