The switch acts as the set point for voltage.CB3L DC Breaker Trip Lamp (33) - The "CB3L DC Bkr Trip" lamp will illuminate if circuit breaker 3 (CB3) has tripped.Fuel Level Gauge (34) - Displays the level of fuel in the fuel tank of the power module. The level is displayed as a percentage.Fuel Control Switch (35) - With this switch in the left position, the fuel pump will unload fuel from the tank. In the right position, the fuel pump will load fuel into the tank. This switch works with the fuel mode switch.Fuel Mode Switch (36) - The position of the fuel mode switch determines if the fuel pump will automatically transfer fuel to or from an external tank. The fuel transfer is determined by the fuel level in auto mode. If the fuel mode switch is manually held in the left position, then the fuel pump will operate regardless of the fuel level. The left position is the manual mode. The fuel mode switch is a three position switch.Fuel Overfill Lamp (37) - The fuel overfill lamp will illuminate if the fuel tank of the power module is above 98 percent full. The fuel overfill lamp will illuminate if the pump has been locked out from pumping more fuel into the tank.Electronic Modular Control Panel 3 (EMCP 3)

Rated positionThe "Idle/Rated" switch will prevent the radiator motor from turning when in the idle mode for only 3516 engine applications.
Do not load the generator when running in the "IDLE" mode.
