normally open SPST switch. Because this switch turns on and off the backup
system, it is must be highly reliable and also protected which would prevent acci-
dental actuation from happening. Some switches have protection covers but
this protection could be simply in where you mount the switch. It should be near
the backup Control Head and yet mounted so the it would not be accidentally
turned on (i.e. when another switch near it is being turned on.) The pilot light
should be wired as per the diagram below. It should be a 12v or 24v DC low cur-
rent light.
D. Installation Checkouts
Once the system has been installed the system must be checked for the proper operation. The basic checks are as fol-
lows:
1) Backup System in General - Once the normally EEC system is up and running and in neutral, turn the back-
up system enable switch on (NOTE: Do NOT have engines running!). At this point the Backup System light should come
on, all the LED's on the Control head should go out. You are now in Backup Mode. Shift the Control Head levers to for-
ward and reverse. You should hear the transmission solenoids "clicking" as you shift the transmission.
2) Start Interlock Operation - With the Control Head in neutral (or even put the system in Warm mode by push-
ing the WARM button) try to start the engine. NOTE: The checkout can be done at the dock, but care must be taken when
shifting gears at the dock. Make sure that dock lines are tight and adequate. (NOTE: You do not have to start it, just try
to turn over the engine with the starter.) The engine should start cranking while the Control head levers are in neutral.
Next push the Port engine control lever into forward gear. Try to start the PORT engine. You should not be able to start
the engine. Put the PORT control lever back to Neutral and then try the STBD side. Make sure you do one side at a time.
If you cannot start in gear but can start the engines in neutral then the Backup system start interlock function is working
correctly.
3) Gear Operation - NOTE: The checkout can be done at the dock, but care must be taken when shifting gears
at the dock. Make sure that dock lines are tight and adequate. Once step 1 and 2 above have been checked, you can start
the engines. Carefully move one Control Lever at a time in and out of gear. Check for proper direction and operation of the
transmissions.
4) Now bring the Control levers to neutral and stop the engines. At this point turn off the Backup System enable
switch and the lights on the Control Head should come on and the EEC system should be in normal operation.
5) At this point make sure that in normal operation , with the EEC turned on, you have proper gear operation.
Carefully move one Control Lever at a time in and out of gear. Check for proper direction and operation of the transmis-
sions.
6) You are now fully tested . Make sure that all operators of the vessel know about the Backup System's operation
and where the backup switch is located.
