QUIETPACT™ 75D Recreational Vehicle Generator

2.1GENERATOR CONTROL PANEL

The following features are mounted on the generator control panel (Figure 2.1):

Figure 2.1 – Generator Control Panel

2.1.1 HOURMETER

This indicates the length of time the engine/generator has operated, in hours and tenths of hours. Use the hourmeter to ensure that the periodic mainte- nance tasks for the generator are completed on a timely basis.

2.1.2 START/STOP SWITCH

To crank and start the engine, hold this switch in the START position. Release the switch when the engine starts. To stop an operating engine, press and hold the switch in the STOP position until the engine shuts off. The switch’s center position is the RUN position.

2.1.3 FUSE

The 14-amp fuse protects the engine’s DC control cir- cuit against electrical overload. If the fuse element has melted open due to overloading, the engine can- not be cranked. If the fuse must be replaced, use only an identical replacement (i.e., SFE-14).

If a fuse element melts, find the cause of the overload before replacing the fuse.

2.1.4 LINE BREAKER

The line (i.e., main) breaker protects the generator’s AC output circuit against overload and provides a method of turning OFF the generator’s 120/240-volt AC output to the vehicle circuits. The QUIETPACT™ 75D has two 35-amp breakers.

NOTE:

Refer to Section 1.4, “Generator AC Connection System,”. Individual installations will differ. If an overload occurs, the dual breakers will open the ungrounded (i.e., hot) stator leads (11 and 44 in Figure 1.1). When the generator has been con- nected for 120 volts only (Figure 2.16, Page 31), the line breakers will operate independently on the ungrounded (i.e., hot) stator leads (11 and 33 in Figure 2.16, Page 31).

2.1.5 PREHEAT SWITCH

The diesel engine is equipped with glow plugs, one for each cylinder. When the preheat switch is pressed, the glow plugs heat the engine combustion chamber, allowing for quicker starts when the engine is cold. Pressing the preheat switch also operates the fuel pump.

2.2OPTIONAL REMOTE START/STOP

This generator is equipped with a plug-in connector that can be interfaced with an optional remote panel provided inside the vehicle. This option allows for starting and stopping the generator conveniently from within the vehicle. Refer to Part II - Installation Instructions, Section 2.8, for details on the remote start/stop option.

2.3BEFORE STARTING THE ENGINE

NOTE:

Instructions and information in this manual assume the generator has been properly installed, connected, serviced, tested and adjusted by a qualified installation technician or installation contractor.

2.3.1 INSTALLATION

Generator installation must have been properly com- pleted so that it complies with all applicable codes, standards, and regulations and with the manufactur- er's recommendations.
