- Undervoltage Protection Value (<U): Set the lower voltage limit (80-210V).
- Undervoltage Recovery Value: Set the voltage at which power is restored after an undervoltage event.
- Undervoltage Operating Time: Set the delay before undervoltage protection activates.
- Fault Recovery Delay Time: Set the delay (1-999 seconds) before power is restored after any fault condition stabilizes.
- Power On Delay Time: Set the delay before the device powers on after initial connection or a power cycle.
- Reset Mode Selection: Choose how the device resets after a protection event.
- Query Faults: Access a log of recent fault events.
- Restore Factory Settings: Reset all parameters to their default values.
7. Maintenance
The Marhynchus CHLT-712 Voltage Protector requires minimal maintenance. Regular inspection can help ensure optimal performance.
- Cleaning: Periodically wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Inspection: Check wiring connections annually to ensure they remain tight and free from corrosion. Inspect the device for any signs of physical damage or overheating.
- Ventilation: Ensure the device is installed in a location with adequate ventilation to prevent heat buildup.
8. Troubleshooting
If you encounter issues with your voltage protector, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No input power; incorrect wiring; internal fault. | Check main power supply. Verify wiring connections. If problem persists, contact support. |
| Output power is off, but input voltage is normal. | Device in protection mode (over/undervoltage); power-on delay active. | Check voltage display for fault indicators. Wait for recovery delay. Manually reset if necessary. |
| Settings cannot be changed. | Not in setting mode; buttons unresponsive. | Press 'M' button to enter setting mode. If buttons are unresponsive, power cycle the device. |
If the issue is not resolved by the above steps, please contact customer support.
