Bennett Marine EIC5000 Electronic Indicator Control - Manual (Page 5)

Calibration and Operation
Calibration – NOTE: If you have Upper and Lower Helm EIC displays installed,
calibration must be done at the Lower Helm EIC display.
Check trim tab system to ensure it is operational, then put both trim tabs in the FULL UP position
by holding down the “Bow Up” position.
The port and starboard 1. red LEDs will flash alternately, indicating that the system is not
calibrated.
Press and hold the sun and moon buttons on the EIC Display simultaneously for 2.
approximately 3 seconds. Both the port and starboard lower yellow LEDs will begin to
flash. Release the sun and moon buttons.
Using the EIC Display, run both trim tabs to the full down position (Bow Down on the control). 3.
Make sure the tabs go all the way dOWN by holding the buttons down for at least
15 seconds or until the lower yellow LEDs stop flashing. (Holding the buttons after the tabs
are down will not harm the system).
A few seconds after the tabs are all the way down the port and starboard 4. upper yellow
LEDs will begin flashing. Again, using the EIC Display, run both tabs to the full up position
(Bow Up on the control). Make sure the tabs come all the way UP by holding the
buttons down for at least 15 seconds or until the upper yellow LEDs stop flashing.
The upper and lower yellow LEDs will then light up solidly, indicating that the EIC is 5.
calibrated and ready to operate. If you wish to recalibrate the EIC at any time, simply bring
the tabs to the full up position, press and hold the sun and moon buttons down and repeat
the calibration instructions.
Operation
The brightness of the display may be adjusted by pressing the sun button to brighten and the
moon button to dim the display.
diagnostic Information
Port and starboard red LEds alternately flash: EIC requires calibration. Follow steps above.
Upper yellow LEd flashes on port or starboard side: Indicates the EIC Display is not receiving
a sensor signal. If the port upper yellow LED flashes, the fault is in the port (red) sensor or wires. A
flashing yellow LED on the starboard side would indicate a fault on the starboard (green) sensor or
wires. Switching the sensor connections on the EIC Relay Module will confirm the diagnostic code
if the flashing LED switches sides. If the problem switched sides, check the suspected faulty actuator
with an Ohm meter at the EIC sensor cable plug. The reading should be in the 220-260 Ohm range.
If the sensor readings are good, check for faulty connections (corrosion or broken wires).
