📝 Parameter Settings

After the installation is complete, configure the settings as follows:

Set knob: D-TIME (Delay Time)
Set two to three seconds longer than the motor starting time.

Set knob: O-TIME (Over-current run time)
Set less than the motor's endurance time with over-current.

Set knob: Load (Rated Current)
Set over 110% of the motor's rated current or under 120% of its operating current.

❓ Frequently Asked Questions (FAQ)

Q1: What protective functions does this relay provide?

A1: It provides complete protection features including Overload, Phase Loss, and Locked Rotor protection to prevent motor damage.

Q2: How do I adjust the D-TIME and O-TIME settings?

A2: The D-TIME (Delay Time) should be set 2 to 3 seconds longer than the motor's startup duration. The O-TIME (Over-current run time) must be configured to be shorter than the motor's maximum endurance time during overload conditions.

Q3: Does the device display diagnostic information when a trip occurs?

A3: Yes, the front panel LED display shows the real-time working current, and when a trip occurs, it clearly displays the cause of the trip in the LED window for troubleshooting.

Q4: Is it compatible with both single-phase and three-phase systems?

A4: Yes, it is highly versatile. You can selectively switch between single-phase (1P) and three-phase (3P) configurations using the built-in DIP switch.

Q5: What are the installation and mounting methods?

A5: The design supports dual mounting options: standard 35mm Din Rail mounting and Panel mounting, ensuring a simple and easy installation process.

Q6: What is the quality guarantee period for the product?

A6: All of our products are covered by an 18-month Quality Guarantee. If any quality issues or complaints arise, a response and solution will be provided within 5 days.
