N40469 Chapter 3 Keyswitch panel overview The keyswitch panel shown in figure 4 is used in conjunction with the digital panel. The switches are protected from the entry of water, but if the control panel is in an exposed location, it should be protected by a cover when not in use. Below is a description of the lamps and switches on the keyswitch panel. 1. Engine crank - turns the engine over. 2. Warning lamp - indicates a problem. 3. Diagnostic lamp - indicates active diagnostics codes. 4. Engine stop switch - stops the engine. 5. Panel on/off switch - energises the panel. Caution: If the audible warning device operates, the warning light(s) on the panel will indicate the engine affected.
Reduce the speed of the engine affected to idle and, if necessary, stop the engine. Throttle synchronization and slow vessel mode panel Figure 4 The function of this switch in figure 5 is to have one of the throttles designated as the master throttle. 1. Engine selection switch. 2. Slow vessel mode switch. 3. Spare switch location. When the switch is not activated, each engine will respond to the appropriate throttle. When activated, all the engines will respond to the master throttle. Slow vessel mode operation This reduces the low idle of the engine to 600rpm. This allows the operation of the vessel at slow speeds with engines in gear for manoeuvring. Figure 5 Page 13
