To Next PageTo Next PageHow to troubleshoot a blank ACU display on a Sea Tel 9711-92 Antenna?
If the Sea Tel Antenna ACU display is blank, first ensure the front panel power switch is ON. Check the AC line voltage on the power cord and the cable connections on the rear panel of the ACU. If the voltage is okay, disconnect the cables plugged into J1 Gyro Compass, J2 NMEA, and J3 M&C one at a time to check if any are shorting the ACU.
What to do if Sea Tel 9711-92 ACU Status displays 'REMOTE NOT RESPONDING'?
If the Sea Tel Antenna ACU status displays 'REMOTE NOT RESPONDING', check the antenna control cable connections at the J4 “Antenna” jack on the rear of the ACU and at the antenna pedestal inside the radome. Ensure these connections are secure.
Why doesn't the Ship's Heading display follow ship movement on my Sea Tel Antenna?
If the Ships Heading display on your Sea Tel Antenna does not follow the ship's movement, first determine the type of gyro compass used. Then, ensure that the GYRO TYPE parameter is set correctly.
Why doesn't the Ship's Heading display change when the ship changes direction on my Sea Tel Antenna?
If the Ships Heading display on your Sea Tel Antenna does not change when the ship changes direction, use a multimeter to measure the voltage between R1 and R2; it should read 115 VAC. If not, a fuse may be blown at the gyro repeater, or there is an open circuit between the repeater and the ACU. Also, measure between S1 and S2, S2 and S3, and S3 and S1; these should all read between 0 and 90 VAC.
What to do if Sea Tel Antenna display changes in the opposite direction of the ship's movement?
If the display changes in the direction opposite of the ship's movement on your Sea Tel Antenna, switch the secondary leads S1 and S2 (Caution: there is 90 VAC between them!). Then, verify that the display changes in the same direction as the ship's movement.
Why is the ship's gyro compass input noisy on my Sea Tel 9711-92 Antenna?
If the ship's gyro compass input is noisy, occasionally inaccurate, or occasionally unavailable on your Sea Tel Antenna, ensure that Satellite Reference Mode is ON.
What causes phase failures during initialization on a Sea Tel 9711-92 Antenna?
Re-configure the PCU of your Sea Tel Antenna. If initialization still fails, this indicates a drive or sensor problem.
What happens if DishScan is OFF and the Step Integral parameter is set to 0000 on Sea Tel 9711-92 Antenna?
If DishScan® is OFF and the Step Integral parameter is set to 0000 on your Sea Tel Antenna, you will get a constant ERROR 0016 (DishScan® error), and you will see zeros flashing in the lower left of the Azimuth and Elevation ENTRY menu displays.
