Menu Structure and Navigation

1. Classification of menu systems

AGC-3 includes two main menu systems:

View menu: For daily use, it includes 15 configurable windows and can be navigated through the directional keys

Settings menu: Used for parameter configuration, requires password access, and operators usually do not need to use it

2. Entrance window

After the device is powered on, the entrance window is displayed, which is the starting point of the menu structure. Press the BACK key three times to return to the entrance window. If there is an alarm when powered on, the alarm list will be displayed directly.

3. View menu structure

The menu is divided into three view levels: V1, V2, and V3

V1 (Manual View Selection): Contains up to 15 windows, manually selected by the up and down arrows, displaying the measurement values selected according to the configuration

V2 (Automatic View Switching): Automatically switches according to the running status, displaying in sequence:

Start preparation

synchronization

Slope lifting

View 4

Default View (Normal Running State)

V3 (Status Display View): The first line displays the running status text, the second and third lines display the measured values, and the fourth line is the selection line

4. Status Text Description

The running status text is displayed on the first line of the V3 view, and common statuses include:

Meaning of Status Text

Island MAN/Semii/AUTO island mode, manual/semi-automatic/automatic status

AMF MAN/SMI/AUTO automatic mains power fault switching mode

FIXD POWER MAN/Semii/AUTO Fixed Power Mode

PEAK SHAVING MAN/SEI/AUTO peak shaving mode

LOAD TAKEOVER MAN/SEI/AUTO load transfer mode

MAINS P EXPORT MAN/SEI/AUTO mains power output mode

Start Preparation: Relay Activation

START RELAY ON/OFF Start Relay Status

Mains Failure: mains power failure and delay ends

COOLING DOWN # # # s Cooling Delay Countdown

After GEN-SET STOPPING cooling is completed, the unit is stopping

5. Mode menu

After pressing the MODE key, the fourth row displays the mode selection menu. Use the directional keys to move the cursor and press SEL to confirm the selection. The available modes include:

Mode Function Description

The SEMI (semi-automatic) button (start, stop, close, open) is valid; The speed regulator automatically controls the speed; Automatically synchronize when closing

TEST starts, runs, and stops the unit according to the preset testing cycle; The main circuit breaker remains closed, and the generator circuit breaker remains open

AUTO automatically operates based on the selected control type (AMF, fixed power, etc.); The button is disabled

The MAN (manual) start/stop button is valid; The speed controller does not automatically adjust; Perform synchronization check before closing the switch

BLOCK prohibits activation; Password required to exit blocking mode

There are three types of test operation modes:

Simple test: Start the unit but do not close it

Load test: parallel with the mains power and load to the preset value

Full test: Transfer the load to the generator set and open the main circuit breaker

Alarm processing mechanism

1. Alarm triggering and display

When the alarm conditions are met, the controller automatically jumps to the alarm list to display the alarm information. If you do not want to view immediately, you can press the BACK key to exit. The alarm list can be accessed at any time through the INFO key.

2. Alarm List Operation

The alarm list displays the following information:

text

G000V1230Genlow-volt1UN-ACKI 2 Alarm(s) ACK FIRST LAST

The first line displays the alarm description

The second line displays the alarm status (UN-ACK indicates unconfirmed)

The third line displays the total number of alarms

The fourth action option: ACK (confirm), FIRST (jump to the earliest alarm), LAST (jump to the latest alarm)

Operation Instructions:

Use the up and down arrows to scroll through multiple alarms

Move the cursor to ACK and press SEL to confirm the current alarm

Move the cursor to FIRST or LAST, press SEL to jump to the earliest or latest alarm

3. Alarm confirmation and clearing

After the alarm is confirmed, if the alarm condition has disappeared, the alarm will be removed from the list. If the alarm condition still exists, the alarm status changes to "confirmed" but still displays in the list. All alarms that have been confirmed and the conditions have disappeared will no longer be displayed.
