Basic Operation and Leakage Protection Test
Follow these steps for normal operation and to periodically test the leakage protection function of your circuit breaker.
ചിത്രം 4: This image illustrates the basic operating instructions. ഘട്ടം 1: To power on, pull up the operating handle (red switch) and ensure the 'R' button is protruding, indicating a power-on state. ഘട്ടം 2: If the handle jumps down automatically and the 'R' button bounces, it signifies a normal power-off state. ഘട്ടം 3: If the 'R' button is pressed and the handle does not jump down, it indicates a problem. ഘട്ടം 4: After a successful test or reset, the device returns to a powered-on state.
ചിത്രം 5: Detailed instructions for inspecting the leakage protection device. ഘട്ടം 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. ഘട്ടം 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. ഘട്ടം 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. ഘട്ടം 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.
വീഡിയോ 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.
