V. SYSTEM FAILURE WARNING MESSAGES..

  • Last update: 03 July 2013

There are six (6) SYSTEM FAILURE WARNING MESSAGES that flash on the key pad whenever the Auto Glide loses any of the required engine or GPS data, loses communication with the Key Pad, if the Auto Glide Control Box becomes loose from its mounting location or if one of the trim tab actuators draws too much current. 

NOTE: While in LIMP HOME MODE, you can press all four (4) of the UP/DN Buttons on the Key Pad and the Auto Glide will display the SYSTEM FAILURE WARNING MESSAGE on the Crosshair LED Indicators.

A. DATA LOSS FAILURE:

There are three types of data loss scenarios that could cause the Auto Glide to flash a SYSTEM FAILURE WARNING MESSAGE: GPS DATA LOSS, ENGINE DATA LOSS, OR KEY PAD COMMUNICATION LOSS.

The following illustrations outline the sequence of flashes that occur on the Key Pad when the Auto Glide loses either GPS or Engine CANBUS data.

Once the Auto Glide completes the initial LED sequence of flashes, it will display the corresponding SYSTEM FAILURE WARNING MESSAGE. 

B. GPS DATA LOSS:

 

C. ENGINE DATA LOSS:

Once the trim tabs have fully retracted or you have pressed an UP/DN Button to override the GPS OR ENGINE

DATA LOSS - SYSTEM FAILURE WARNING MESSAGE, the Auto Glide will default to LIMP HOME MODE. You can read more about LIMP HOME MODE on pages 29 thru 32.

 

D. KEY PAD COMMUNICATION LOSS:

 

The Auto Glide Key Pad is a CANBUS based device that communicates with the Auto Glide Control Box via NMEA 2000 protocol. The Key Pad is in constant communication with the Control Box as it sends and receives boat control messages.

 If the Key Pad fails to communicate with the Control Box, the Auto Glide will stop all automatic boat control decisions and retract the trim tabs in short bursts. The Key Pad will also go blank and none of the Key Pad buttons will respond.

 

E. REACQUIRED DATA LOSS:

The Auto Glide will remain in LIMP HOME MODE (or blank when the Key Pad loses communication) until either the lost GPS or engine data is reacquired, the Key Pad regains communication with the Control Box or you turn “OFF” your motor(s). Once the Auto Glide reacquires the lost data, it will flash a REACQUIRED DATA – SYSTEM FAILURE WARNING MESSAGE and then default to MANUAL MODE.

Once the Auto Glide defaults back to MANUAL MODE, you can either continue to control the trim tabs manually or you can select any of the four (4) AUTOMATIC SETTING BUTTONS.

 

F. ACTUATOR OVER-AMPERAGE:

The Auto Glide constantly monitors the amp draw of each actuator in the trim tab system. In the event that an actuator draws too much current and begins to malfunction, the Auto Glide will flash an ACTUATOR OVERAMPERAGE WARNING MESSAGE, default to LIMP HOME MODE and lockout the failed actuator in whichever direction it was moving at the time of the failure (extending or retracting).

The ACTUATOR OVER-AMPERAGE message will indicate which actuator has failed and in which direction it failed. Once the Auto Glide defaults to LIMP HOME MODE and locks out the failed actuator, you will not be able to move it in the same direction that it was moving at the time of the failure. However, you will be able to move the failed actuator in the opposite direction.

An example of an ACTUATOR OVER-AMPERAGE failure would be when the Auto Glide is attempting to extend the trim tabs during an automatic boat control decision, but the starboard actuator fails due to high current draw. The Auto Glide will flash an ACTUATOR OVER-AMPERAGE – SYSTEM FAILURE WARNING MESSAGE, default to LIMP HOME MODE and lock out the actuator from extending any further. You can manually retract the failed actuator by pressing the corresponding UP BUTTON. The following illustration outlines this example:

EXAMPLE: ILLUSTRATION OF ACTUATOR OVER-AMPERAGE FAILURE

STEP 1 – AUTO GLIDE SENSES OVER-AMPERAGE FAILURE

STEP 2 – AUTO GLIDE DISPLAYS SYSTEM FAILURE MESSAGE AND DEFAULTS TO LIMP HOME

Once the Auto Glide defaults to LIMP HOME MODE and displays an ACTUATOR OVER AMPERAGE FAILURE MESSAGE, you will have to turn your motor(s) “OFF” and then “ON” again to reset the Auto Glide.

 

G. CONTROL BOX OUT OF OPERATIONAL TOLERANCE:

The Auto Glide Control Box contains sensors that measure roll angles, pitch angles and yaw (rate of turn). When the Auto Glide Control Box is attached to the boat, the sensors measure the boat’s roll angles, pitch angles and yaw. If the Control Box becomes detached from its mounting location, these measurements would become inaccurate.

To protect from these potentially inaccurate pitch and roll readings, the Auto Glide constantly monitors the maximum pitch and roll angle changes the boat makes at any given time. If the changes in roll or pitch angle exceed a predetermined threshold for more than 10 seconds, the Auto Glide will flash a OUT OF OPERATIONAL TOLERANCE WARNING MESSAGE, stop all automatic boat control decisions and default to LIMP HOME MODE.

Once the Auto Glide defaults to LIMP HOME MODE and displays an OUT OF OPERATIONAL TOLERANCE FAILURE MESSAGE, you will have to verify the Auto Glide Control Box is installed properly (See Section 2.3 in Owner’s Manual A) and then reset the Auto Glide by turning your motor(s) “OFF” then “ON” again.
