SECTION 1 : SAFETY PRECAUTIONS
Ensure all necessary procedures have been completed correctly.
Failure to follow the correct procedures may lead to permanent damage to the equipment.
Failure to follow the correct procedures may result in personal injury or death.
This manual contains information on the installation, wiring, application, operation, and maintenance of the GCU-5K
Auto Start Control & Ptorection Module for Generator. It should be thoroughly read before operation.
The installation, wiring, and parameter settings of the GCU-5K Auto Start Control & Protection Module
should be performed by qualified professional technicians. Improper installation, wiring, or parameter
settings may lead to personal injury or equipment damage.
Use fine fiber cloth with clean water or neutral screen cleaning liquid for gentle wiping DP-
70G LCD
display panel. Do not use organic solvent cleaners (ex. alcohol, toluene, or acetone) to wipe the LCD
display panel, or it may cause the panel to become fogged, yellowed, or rough.
SECTION 2 : GCU-5K Component Overview
Upon arrival of the product, it should be immediately unboxed and inspected for any external damage caused by
impacts during transportation. Also, check if the standard accessories (listed in Table 2.1) are complete. If any items
are missing or damaged, please contact us or the distributor from whom you purchased immediately.

3.1.3 Precautions for Assembly Wiring
The GCU-5KC control unit is equipped with wiring fixture on both sides. After the assembly wiring of the unit is
completed, all control wires should be securely fastened to the wiring fixture using cable ties. This reduces the
possibility of poor contact or failure due to vibrations.
3.2 Wiring Installation of the GCU-5KC and DP-70G
The GCU-5KC control unit and DP-70G display panel are connected by a standard DB9 connector cable.
1. If the DB9 cable is not properly secured, severe vibrations from long periods of generator operation
may lead to poor contact or loosening of the connectors.
2. A loose DB9 connector will result in a disconnection between the GCU-5KC and DP-70G. The
DP-70G will not function properly and remote monitoring operations cannot be performed.

3.3 Wiring Assembly of the GCU-5K and Generator
Follow wiring connection steps below
1. Complete all wiring connection (except the battery cables).
2. Check whether all wiring connections are correct.
3. Connect the battery power.
4. Set the GCU-5K to the "STOP" position.

SECTION 5 : GENERATOR OPERATIONAL TEST
5.1 Main Menu Introduction
Pressing the multi-function knob to enter the Main function menu. The operation mode are detailed as follows:
●STOP: 1) Generator shutdown immediately without engine cooling down delay
2) If there's a shutdown alarm due to a fault, pressing STOP can clear the fault alarm message and sound.
●START：Manually force the generator to start. (Unless the fault alarm message is not cleared)
●AUTO：Press "AUTO". The word "AUTO" blinking at the bottom left of the screen indicates standby mode. Once
the genset enters the operation mode, the word "AUTO" will stay lit. In “AUTO” mode, the Start / Stop of
the genset will be controlled by remote start signal.
●Ethernet Enable/Disable: This setting enables or disables the Wi-Fi connection feature of the device.
●Event Log：Selecting the Event Log option allows access to the history list of the generator events, which aids
in fault diagnosis, (refer to section 6.1.3).
●System Setting：Before executing On-Site system parameter setting, the setting permission must be unlocked
by pressing and holding the Owner button in STOP mode.
●J1939 Paramater：This option provides the SAE J1939 parameter list for the electronic engine, but only appears
when the engine type is set as an electronic engine. (Refer to section 6.1.4).
●Other Setting: This option includes the following settings.
✽Meter Setting: This item allows the execution of the graphical needle meter display replacement function.
✽Wi-Fi WPS Setting: Execute the Wi-Fi network MAC address and SSID setting, (refer to section 6.3.1.1).
✽Wi-Fi AP Setting: Execute the Wi-Fi setting on GenOnCall®App (refer to section 6.3.1.2).
✽Firmware Update Execution: Execute firmware update when displayed at Information Bar.
✽Zero Correction for Ammeter: Click this item to perform ammeter zero calibration.
●About This Device: The content includes information related to GCU-5K firmware version, product serial
number, currently connected Wi-Fi MAC / SSID, and location coordinates.
Be sure "Emergency Stop Button" must be pressed before working on genset maintenance to avoid of
personal injury. The generator will be locked in at OFF state until the “Emergency Stop Button” is
pressed again to unlock it.
When Ethernet control is activated, GCU-5K will execute STOP / START / Auto modes based on the most
recent command received (through Ethernet or On-Site).
5.2 Trial Run Operation
Once the generator unit has been fully assembled and wired, and all system parameters have correctly set, the user
should execute generator operation in START and AUTO, this is to ensure that the assembly wiring and control
module parameter settings meet the unit's control and protection requirements.
5.2.1 Inspection Items
1. Emergency Stop Button Function
4. Low Oil Pressure Protection Function
2. Over Speed Protection Function
5. All display screen
3. High Collant Water Temperature Protection Function
5.2.2 Start-Up Procedure
Select START on the operating panel. GCU-5K will immediately execute the start-up procedure according to the
system settings until one of the following conditions occurs:
Starter motor operation interval stop Starter motor operation interval stop Starter motor operation.
●Engine oil pressure reading established (Must be set to detect engine start with oil pressure reading)
●Engine oil pressure switch action (Must be set to detect engine start with oil pressure switch)
●AC voltage builds up
●AC frequency reaching a rated value of 18 Hz or above
●MPU frequency reaching above the start standard (Must be set to detect engine start with MPU)
