The inputs describe the status of the machine systems. Two types of inputs exist. The inputs can be either a switch type or a sensor type. Switches provide an open, a ground, or a + battery signal to the inputs of the controller. Sensors (frequency, PWM, or voltage) provide a changing signal to the sensor inputs of the controller. The controller will recognize the following types of sensor signals:
Frequency - The sensor will produce an AC signal (sine wave or square wave) that varies in frequency (Hz) as the condition changes.
Pulse Width Modulated - The sensor produces a digital signal and varies the duty cycle as the condition changes. The frequency of the signal will remain constant.
Sometimes the operator is provided a manual switch that can be used to change a condition of the machine.
There are three buttons that are part of the generator system.
The magnet control button is an operator control that is in the cab of the machine.
To ENABLE the hydraulically driven generator, UNLOCK the hydraulic system, then press the Magnet Control button. When the generator is ENABLED, the indicator light on the button will illuminate, and the engine speed will increase to high idle. Press the button again to DISABLE the magnet. The indicator light on the button will not illuminate, and the engine speed will decrease to low idle.
There are two joystick triggers that control the magnet.
Magnet disengage trigger is on the left joystick. Push this button to disengage the magnet.
Magnet engage trigger is on the right joystick. Push this button to engage the magnet.
The ECM responds to decisions by sending electrical signals to the outputs. The outputs can create an action or the outputs can provide information to the operator or the service technician.
Solenoid Valve for Generator Enable

The solenoid valve for generator enable is located above the generator motor. The solenoid valve controls signal oil to the generator pump controller. The ECM sends an electrical signal to the solenoid valve to supply discharge oil to the pump controller to rotate the generator at speed.
The IQAN control system uses CAN-buses to communicate between IQAN modules, and other systems. The CAN-bus is a robust communication protocol. The buses were configured using IQAN software to SAE J1939 defined CAN protocol. The Master Controller and Monitor (MD3) has 3 CAN buses; MD3 CAN-A, MD3 CAN-B, MD3 CAN-C. Electronic control module 4 (MC2) has a separate CAN bus, MC2 CAN-B. A personal computer with IQANrun software installed will allow communication with the IQAN machine control system for diagnostic and troubleshooting.
