Basic Operation and Leakage Protection Test
Follow these steps for normal operation and to periodically test the leakage protection function of your circuit breaker.
Billede 4: This image illustrates the basic operating instructions. Trin 1: To power on, pull up the operating handle (red switch) and ensure the 'R' button is protruding, indicating a power-on state. Trin 2: If the handle jumps down automatically and the 'R' button bounces, it signifies a normal power-off state. Trin 3: If the 'R' button is pressed and the handle does not jump down, it indicates a problem. Trin 4: After a successful test or reset, the device returns to a powered-on state.
Billede 5: Detailed instructions for inspecting the leakage protection device. Trin 1: With the operating handle pulled up and the 'R' button not protruding (power-on state), press the 'Test' key to test the leakage protection device. Trin 2: If the handle jumps down automatically and the 'R' button bounces, the device is in a power-off state, indicating the leakage protection device is functioning normally. Trin 3: If the 'Test' switch is pressed and the handle does not jump down, and the 'R' button does not automatically pop up, the device is in an energized state, indicating a problem with the leakage protection device, and it cannot provide protection. A new leakage device needs to be replaced. Trin 4: After a normal inspection (handle automatically jumps down, 'R' button automatically pops up), the device is in a power-off state. Press the 'R' button that just popped up, and then pull up the operating handle to power on the appliance normally.
Parameter Setting (Adjustable Voltage and Current Protector)
The EARU Circuit Breaker allows for adjustment of various protection parameters. The following video demonstrates how to set these parameters.
Video 1: This video demonstrates how to adjust the protection parameters on an EARU Adjustable Voltage and Current Protector. It shows setting the overvoltage (P-1, range 240-300V), undervoltage (P-2, range 140-200V), overcurrent (P-3, range 1A-40A/63A/80A), reset/start delay (P-4, range 1s-300s), and relay recovery delay (P-5, range 1s-300s) settings. The video also shows the overcurrent recovery delay (P-6, range 1s-300s). This process involves pressing the 'SET' button to enter programming mode and using the up/down arrows to adjust values.
