6. Description of switch status display

6.1 Circuit breaker status indication (passive contact input)

The green analog bar lights up when the circuit breaker is opened

When the circuit breaker is closed, the red analog bar lights up

6.2. Hand cart position indication (passive contact input)

When the test position contacts are closed, the green simulation bar lights up

When the working position contacts are closed, the red analog bar lights up

6.3. Grounding knife status indication (passive contact input)

When the grounding knife is disconnected, the green analog strip lights up

When the grounding knife is closed, the red simulated strip lights up

6.4. Spring energy storage status indication (passive contact input)

When the circuit breaker operating mechanism is not storing energy, the spring symbol appears green

When the operating mechanism of the circuit breaker has stored energy, the spring symbol appears in red

Note: All status display input signals are taken from the auxiliary contacts of the primary components in the switchgear (passive contact type).

6.5. Voice anti error prompt (optional function)

1) When the circuit breaker is in the closed state and the handcart is mistakenly pushed from the test position to the working position, or when the handcart is mistakenly pushed from the working position to the test position, a voice prompt will appear saying "Please disconnect the circuit breaker";

2) When the grounding switch is in the closed state and the handcart is mistakenly pushed from the test position to the working position, a voice prompt will appear saying "Please disconnect the grounding switch";

3) When the circuit breaker is in the closed state and the grounding switch is in the closed state, and the handcart is mistakenly pushed from the test position to the working position, a voice prompt will appear saying "Please disconnect the circuit breaker, please disconnect the grounding switch";

4) When the handcart is in the working position and the grounding switch is accidentally operated, the voice prompt "Please disconnect the grounding switch" appears when it is closed;

7. High voltage live indication

Indicate that the starting voltage is greater than 0.08 bus voltage

Locking start control voltage>0.08 bus voltage

Lock output contact normally closed passive contact rated capacity AC220V/3A

Warning: Merely relying on a live indicator is not enough to prove that the system is no longer live; If the program requires it as a mandatory requirement, relevant voltage detectors or voltage detection devices that comply with IEC61243 should also be used.

8. Temperature and humidity control

8.1 Two channel temperature and two channel humidity

When the ambient temperature is below the lower temperature limit, the device automatically starts the heater to heat up, and the ambient temperature begins to rise. When it reaches the temperature at which heating stops (i.e. the lower temperature limit+temperature return value), the device automatically stops heating.

When the ambient humidity is higher than the set value, the device automatically starts the heater to heat up, and the ambient humidity begins to decrease. When the humidity drops to the point where heating stops (i.e. the humidity set value humidity return value), the device automatically stops heating.
