Introduction:

GU320a is a kind of intelligent controller of generator which adopt high grade CMOS chip. It can configure the control procedure and protection parameters of the generator, including lots of function such as measuring, controlling, protection, three remote and so on, which completely satisfied the automatic controlling requirement of different generator sets for the generator user or factory. The controller measure and display all parameters the generator output, and the rotating speed, oil pressure, temperature, DC source voltage, running time of the engine and so on. All of the voltage measured in real virtual value to ensure the accuracy of the data. Including big LCD display and menu selection for Chinese and English. The keys on the control panel are used to select the control mode, start the running procedure, display data, and modify the running protection parameters. The LED indicates the operating mode of the controller and the running state of the generator sets. LCD display each measured parameter and state. The controller is integrated closely by aluminum alloy panel and steel shell which has been spurt powder. All connection of the controller are connected by pin-like terminal with lock, such device can be connected 、moved 、maintained and replaced easily easil y and conveniently. conveniently.

This manual is available for the generator intelligent controller cont roller GU320a GU320a only, which you should carefully read before use 2

Operation panel

The whole Operation panel is divided into three parts: LED display for measuring parameters 、operating keys and runningstatus LED indicate。 3.1 LCD and its controlling keys

LCD with 128×64mm lattice can display multiple multiple lines of data information simultaneo simultaneously usly and additive background-light function which make operators read information whenever day or night. To turnoff the background-light, just keep pressing any key for a while. LCD and its control keys provide a friendly operating interface for operators, operators can read information and setting running parameters conveniently. conveniently.

3.3 Operating keys and LED Name

Function

AUTO key/LED The key is used for “auto-operate mode”. Running in this mode, the LED above the button will illuminate. According to the “remote control startup input signal”, the controller determines whether the generator startup or not.

MAN Key / Indicator Light The key is used for “manual-operation mode”. Running in this mode, the LED above the button will illuminate. By pressing “START” and “STOP” key, the controller will start or stop the generator.

TEST Key/ Indicator Light The key is used for testing operation mode settings. Running in this mode, the indicator light on the key on. Here, when the

remote control startup input

“

signal” simulated by the controller is valid, the generator startup. When it switch other mode, the generator stops.

START Key/LED The key is used for generators manually startup. And when the controller is in manual-operation manual-operation mode”, press this key to start the generator. Till the controller

“

performing the start procedure to the Gen set run in normal, the LED above the key on. After the Gen set running normally, the LED above the key on.

Ma n u a l

STOP/RESET key /LED Used to stop the generator by hand, when the controller set in “MAN” mode, this key could stop the generator. Press this key more than 2 seconds can release the fault stop lock if there is fault output. (When the controller performing the stop procedure, the indicator light above the key illuminate. If failed to stop, the light flash.)

LAMP TEST / MUTE key Alarm mute and lamp test key. Press the key more than 2 seconds, all LEDs on the panel will light. It used to test all LEDs on the panel. When Pre-alarm Pre-alarm or fault alarm occur, press this key can mute the buzzer. At the same time the light above the key illuminate. Press it again will cancel mute. If the controller still in fault, the buzzer will keep alarm.

Installation guide

4.1 Hatch size for for panel installation as the figure attached. Four special screws fix the controller. If the shell of the controller is installed on the body of a generator directly or other violent vibratory device, preventing device must be installed.

4.2 Connection for control line line please refer to the diagram attached and the typical wiring diagram 2.3 above. 4.3 Oil pressure and temperature sensor installation of the engine:
