1. Set the Voltage Select Switch to 240/120V position. 2. Start the engine. 3. Immediately adjust the Voltage Adjust for 240VAC nominal before the 20 second timer expires. 4. The new 240V nominal voltage is now locked in. This procedure must be performed whenever the nominal voltage is changed. MN2417 Operation 4-7 Pre.Start Procedure Before attempting to start the generator set, several things must first be verified or performed. These are: 1. Fill system fuel tank with clean, fresh diesel fuel

After these checks have been performed and the system operation is verified to be good, refer to Section 5 Maintenance for periodic checks that must be performed at scheduled intervals to ensure continued operation with minimal problems. WARNING: Disconnect the battery’s ground terminal before working in the vicinity of the battery or battery wires. Contact with the battery can result in electrical shock when a tool accidently touches the positive battery terminal or wire. The risk of such shock

WARNING: A battery presents a risk of electrical shock hazard and high short circuit current. Electrical shock can cause serious or fatal injury. Never wear jewelry, watch or any metal objects when in the area around the battery. WARNING: Check fuel tank, fuel line, and connections monthly for fuel leaks. Diesel is flammable and can cause fire, explosions, injury or death. If a leak is found, replace only with approved pipe or components. Continued on next page. MN2417 Product Safety Information

Operation in any manner not described in this manual should be considered unsafe and should not be attempted. Never start the engine unless you have first verified that the installation and operation of the generator are as described in this manual. WARNING: Be sure that you are completely familiar with the safe operation of this equipment. This equipment may be connected to other machines that have rotating parts or parts that are controlled by this equipment. Improper use can cause serious or

For improved output accuracy, Model 80 employs a built-in counter. This counter is incorporated in an internal loop which constantly monitors the output frequency. Even the slightest deviation from the programmed frequency is detected and corrected by the microprocessor circuit. Model 80 features self-calibration and self-diag-nostic functions that can be operated anytime from the front panel or GPIB command. The self-calibration function compares the output signal parameters to built-in interna
