Generator Function component connectionsNote: The Generator attachment can only be installed on the M318D MH and the M322D MH machines.When the Generator attachment is set to the "Installed" status on the machine, the ECM will energize the Generator Solenoid to disable the Generator. The Generator must be selected as the active tool for the ECM to enable the operation of the Generator using the Generator Enable Switch. The Generator Enable Switch is located on the right switch console.When the Generator is enabled, the ECM will de-energize the Generator Solenoid in order to enable the Generator.When the Generator is selected as the active tool, a minimum engine speed must be maintained. A minimum engine speed is maintained to provide enough power to drive the Generator. For the M318D MH, engine speed must be at least 1500 rpm or more. For the M322D MH, engine speed must be at least 1300 rpm or more. The next higher speed dial position for these speeds should be the minimum setting.When the Generator is installed on a machine, a Magnet Lockout Relay will be installed on the machine. The Machine ECM will use the relay to prevent the magnet from being deactivated when the Implement Lockout function is ON.When the Generator is selected as the active tool and enabled with the Generator Enable Switch, the ECM will turn ON the sinking driver circuit. The sinking drive circuit energizes the Magnet Lockout Relay. The energized relay will enable the operation of the left joystick trigger switch for the control of the magnet.When the Implement Lockout function is ON, the ECM will turn OFF the sinking driver for the relay to disable the left joystick trigger switch.
