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. 2. Fill engine crankcase to full mark with clean, fresh lubricating oil per engine manufacturer operating guide. 3. Radiator coolant should be checked at the beginning of each day and filled in compliance with the engine manufacturer’s guidelines. 4. Secure the generator for operation. a. Skid mounted . the power generating system should be mounted to a smooth, hard surface suitable for supporting the system under all stress conditions. b. Trailer mounted . block wheels to prevent accidental movement. Use jack (Figure 4-1) to level the generator. c. Adequate clearance must be provided for access doors to fully open. Note: The exhaust also exits radiator end. When positioning a generator system ensure position does not cause a concentration of toxic emissions. 5. Place voltage select switch in the correct position 208/120, 240/120 or 480/277VAC and pad lock it in position if required (Figure 4-3). 6. Carefully inspect all Individual load cables for broken insulation or other signs of damage. Never use a damaged cable. Replace it before usage. 7. L1, L2, L3, Neutral and Ground cables must be brought into load block compartment through access hole in base of enclosure. 8. Ensure that wires are properly connected and connections are secure. 9. Ensure that an external ground connection is made when required for safety. 10. Ensure that the Remote Start wires are properly connected, if used. 11. Use disconnect at the load to turn off the load. Do not start engine with load switched “On”. and warm up before load is switched on. 12. Manually start the engine, allow engine to come up to speed and perform the Voltage Reconnect and Adjustment within the allotted time. 13. Stop the engine. Caution: Large “Engine Compartment Doors” on each side of enclosure must remain closed during operation. If doors remain open, engine will overheat due to insufficient air flow around engine. 14. Ensure that Engine Compartment doors are closed for proper ventilation. Note: Receptacle Panel Load cables may be routed into the receptacle compartment through the Enclosure Electrical Access Panel after generator is started and has warmed up. Operating Procedures The engine.generator controller is designed to start and stop an engine from either AUTO “Automatic” mode or Manual “NOT IN AUTO”. Refer to Figure 4-6. Manual Start Procedure 1. Press PAGE until the “OFF AUTO MAN” display is shown. 2. Press Mode until control is in MAN mode. 3. Press “Start”. 4. The controller will start the engine. Manual Stop Procedure 1. Use disconnect at the load to turn OFF the load. Allow generator cool down if needed. 2. Press “Stop”. Press Mode until control is in OFF mode. AUTO Start Procedure 1. Press Mode until control is in AUT mode. In Auto mode, the generator will start when the remote start input closes. 2. In Auto mode, the generator will stop when the remote start input opens. 4-8 Operation MN2417 Digital Engine Controller Description EM0046A21 (MRS17) Figure 4-6 Operator Control Panel Operating Modes and Horn & Fault Reset Manual Run Display Stop Menu Group LED Indicators Note: The operator control panel is equyipped with a heater element that allows the LCD display to operate to .40°C (not the entire generator set, see generator specifications). This heater operates from the main battery power. LED Indicators Alarm (red) . Alarm (shutdown) condition occurred. Annunciates & shuts down generator. Not In Auto (red) .
