Bennett Marine Auto Tab Control - Manual (Page 7)

BE PRUDENT — IF IT APPEARS THE ATC SYSTEM IS CAUSING YOUR BOAT
TO REACT IN AN UNDESIRABLE MANNER, STOP THE BOAT –
THEN INVESTIGATE THE PROBLEM.
Trim tabs and the ATC system have a significant effect on the operation and
versatility of your boat, and nobody knows your boat better than you. The best
learning method is to spend time getting familiar with your boat’s reaction to the
trim tabs and ATC system. Always operate your boat with safety first in mind.
SECTION 6
TROUBLESHOOTING THE SYSTEM
1. Activating the ATC system causes the boat to list (lean).
Trim tab tubing or wiring may be crossed. See the “Before Installing the •
Auto Tab Control” section of this manual.
ATC system Zero Point may be incorrectly set. •
2. The boat slows or is hard to steer.
It is likely that the boat is in an overtrimmed condition. The Zero Point
should be reset with the bow slightly higher.
3. All LEDs on the ATC Keypad flash simultaneously.
Control Unit signal is interrupted. Check Keypad cable for breaks and
check firmness of connection into ATC Control Unit.
4. “SET ZERO” light flashes.
No Zero Point has been set. Refer to Section 3 of this manual.
5. ATC system shuts off by itself.
Control Unit may be receiving low voltage (less than 7 volts). •
If the boat is in a severe list (greater than 26 degrees), the trim tabs will •
fully retract and the ATC system will automatically turn off.
6. The ATC attempts to make a particular attitude correction several times
and is unable to affect the boat’s attitude.
The boat may be going too slow or the trim tabs may be undersized.
NOTE: The ATC attempts to make a particular attitude correction
several times. It forces the trim tabs to remain in a particular
corrective position until the attitude changes. If it appears the trim
tabs frequently cannot correct an out-of-trim position, the trim tabs
may be undersized or boat speed too low.
