Air-cooled 11 kW Generators

‹3.6.5 LOW BATTERY

The microprocessor will continually monitor the bat- tery voltage and turn on the Low Battery LED if the battery voltage falls below 11.0 volts for one minute. Low battery voltage is a non-latching alarm, which will automatically clear if the battery voltage rises above 11.0 volts.

The control system will not attempt to start the engine if there is a low battery condition, however, if the engine is already running when the low bat- tery condition occurs, the engine will continue to run as long as possible.

Battery voltage is NOT monitored during the crank cycle.

4.1SYSTEM FUSE

The generator panel’s 15 amp fuse (Figure 4.1) pro- tects the DC control circuit against overload. The fuse is wired in series with the battery output lead to the panel. If the fuse element has melted open, the engine cannot crank or start. Replace the fuse using only an identical 15-amp replacement.

‹4.1.1 7.5 AMP FUSE

The generator panel’s 7.5 amp fuse protects the accessory outlet against overload. If the fuse element has melted open, there will not be power at the acces- sory outlet. Replace the fuse using only an identical

7.5amp fuse. To remove fuse, push cap down and rotate counterclockwise.

4.2CHECKING THE ENGINE

OIL LEVEL

For oil capacities, see “Specifications,” Section 1.5. For engine oil recommendations, see Section 4.3.1. To check the engine oil level, proceed as follows (Figures 4.2):

1.Start the generator by moving the AUTO/ OFF/ MANUAL switch to the MANUAL position. Allow it to run for a short while and then shut it down by moving the switch to the OFF position.

2.Remove the dipstick and wipe it dry with a clean cloth.

3.Install the dipstick; then, remove it again. The oil level should be at the dipstick “Full” mark. If nec- essary, add oil to the “Full” mark only. DO NOT FILL ABOVE THE “FULL” MARK.

Never operate the engine with the oil level below the “Add” mark on the dipstick. Doing this could damage the engine.

4.Install the dipstick.

5.Reset the AUTO/OFF/MANUAL switch to its origi- nal position.

4.3 CHANGING THE ENGINE OIL

‹ 4.3.1 ENGINE OIL RECOMMENDATIONS

Use oil of American Petroleum Institute (API) Service Class SG, SH or SJ. Use all season SAE 5W-30 Synthetic oil. Organic break-in oil is required before using synthetic oil.

NOTE:

The unit is supplied with “break-in” oil. See the “Break-in Procedure,” Section 3.1, for the first required oil change.
