Section 2 — Operation

Carrier Air-cooled 7 kW, 12 kW and 15 kW Generators

Servicing of the battery is to be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.

When replacing the battery, use the following type of battery: Group 26 12-volt DC, negative ground battery with a rating of 350 cold-cranking amps minimum for 7 kW; 525 cold-cranking amps minimum for 12 and 15 kW at -17.8°C (0° F) minimum. When using a maintenance- free battery, it is not necessary to check the specific gravity or electrolyte level. Have these procedures performed at the intervals specified in the “Service Schedule.” A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure the battery is correctly connected and terminals are tight. Observe battery polarity when connecting the battery to the generator set.

2.1BREAK-IN PROCEDURE

Once the unit has been installed and all electrical checks have been made, it is strongly recommended that the following “Break-in Procedure” be completed to ensure correct generator operation in the future.

1.	Set the generator’s AUTO/OFF/MANUAL switch to
	AUTO.
2.	Turn OFF the utility power supply to the transfer
	switch using the means provided (such as a utility
	main line circuit breaker).

12.Drain the oil and remove the oil filter. Replace the oil filter according to Section 3.4, “Changing the Oil Filter”. Replace the oil with synthetic oil as recommended in Section 3.3, “Changing the Engine Oil”.

13.Reconnect the battery cables as outlined in “General Hazards” (page 2) and insert the 7.5A and 15A fuses into the generator control panel. The generator is now ready for service.

2.2USING THE AUTO/OFF/MANUAL SWITCH (FIGURE 2.1)

‹2.2.1 “AUTO” POSITION

Selecting this switch position activates fully automatic system operation. It also allows personnel to start and exercise the engine every seven days with the setting of the exercise timer (see Section 2.6). This position also is used for remote starting, when it is set up.

‹2.2.2 “OFF” POSITION

This switch position shuts down the engine. This position also prevents automatic operation.

3.	The unit will start, and the transfer switch will transfer
	to standby.
4.	Using the transfer switch’s built-in emergency load
	center, turn on circuits to load the generator to
	approximately 25% rated load and run the unit for
	one hour.
5.	Run the unit for one hour at 50% rated load.
6.	Run the unit for one hour at 75% rated load.
7.	Run the unit for one hour at 100% rated load.

8.	Turn ON the utility power supply to the transfer
	switch, which will allow the transfer switch to transfer
	back to utility power. The unit will continue to run for
	one minute and then shut down.
9.	Allow the unit to cool.
10.	Set the generator’s main circuit breaker to its OFF (or
	OPEN) position.
11.	Set the generator's AUTO/OFF/MANUAL switch to
	OFF. Remove the 7.5A and 15A fuses from the
	generator control panel. Disconnect the battery
	cables as outlined in “General Hazards” (page 2).

‹2.2.3 “MANUAL” POSITION

Set the switch to MANUAL to crank and start the engine. Transfer to standby power will not occur unless there is a utility failure.

With the switch set to AUTO, the engine may

!crank and start at any time without warning. Such automatic starting normally occurs when utility power source voltage drops below a preset level or during the normal exercise cycle. To prevent possible injury that might be caused by such sudden starts, always set the switch to OFF and remove the fuses before working on or around the generator or transfer switch. Then, place a “DO NOT OPERATE” tag on the generator panel and on the transfer switch.
