5. Installation
IMPORTANT: Ensure all power is disconnected before proceeding with installation.
5.1 Mounting
- The CHLT-GX2 is designed for installation on a standard 35mm DIN rail.
- Securely attach the device to the DIN rail in an appropriate electrical enclosure, ensuring adequate ventilation and clearance.
5.2 Wiring
Connect the power sources and load to the designated terminals as shown in the wiring diagram. Use appropriate wire sizes (0.5mm²-1mm²) for all connections.
- Input Terminals (IN): Connect the main power supply (e.g., public grid, generator, inverter) to the N, L1, L2, L3 terminals. The device supports three-phase input.
- Output Terminals (Output): Connect the load to the N and L terminals on the output side.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.

6. Operation
After successful installation and power-up, the ATS will display current voltage and current readings. The device operates automatically to manage power transfer.
6.1 Powering On/Off
- Once wired and power is supplied, the device will automatically power on and display readings.
- Use the power button (usually marked with a circle and vertical line) on the front panel to manually switch the device on or off if needed for maintenance or specific operational requirements.
6.2 Understanding the Display
The digital display shows real-time voltage (V) for L1, L2, L3, and current (A) for the output. Status indicators (L1, L2, L3, Fault) provide operational feedback.
6.3 Setting Parameters
The CHLT-GX2 allows customization of various parameters using the 'M' (Menu) button and arrow buttons (up/down).
- Accessing Menu: Press the 'M' button to enter the parameter setting mode.
- Navigating Parameters: Use the up/down arrow buttons to scroll through different settings such as Auto Reclosing Delay (Ton), Return Priority Stage Delay, Overvoltage Trip Delay, Undervoltage Trip Delay, etc.
- Adjusting Values: When a parameter is selected, press 'M' again to enter edit mode, then use the up/down arrows to change the value. Press 'M' to confirm and save the setting.
- Priority Setting: The device prioritizes power sources (L1>L2>L3) and allows for adjustable voltage thresholds to determine when switching occurs. Refer to the detailed parameter list in Section 4 for specific ranges.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your ATS.
- Cleaning: Periodically clean the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure no dust accumulates in ventilation openings.
- Inspection: Annually inspect all wiring connections for tightness and signs of wear or corrosion. Check for any physical damage to the device casing or terminals.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature failure.
8. Troubleshooting
If you encounter issues with your Hilitand Automatic Transfer Switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | No input power; Loose wiring; Internal fault | Check power supply; Verify all wiring connections; Contact support if power is present but device remains off. |
| ATS not switching power sources | Voltage outside set thresholds; Delay settings; Faulty power source | Check input voltages; Review and adjust delay and voltage threshold settings; Verify backup power source functionality. |
| "Fault" indicator illuminated | Overcurrent; Over/Undervoltage; Internal error | Check load current; Verify input voltages are within acceptable range; Disconnect power, wait, then reconnect. If fault persists, contact support. |
| Inaccurate voltage/current readings | Loose connections; Sensor issue | Check wiring connections; Contact support for calibration or repair. |
If the problem persists after attempting these solutions, please contact Hilitand customer support for further assistance.
