What to do if TAVRIDA ELECTRIC Circuit breakers CM “Malfunction“ LED lights continuously?
If the CM “Malfunction“ LED is continuously lit, this indicates an internal fault within the CM (Control Module). The suggested solution is replacement of CM.
What to do if TAVRIDA ELECTRIC VCB Circuit breakers ISM cannot perform close/trip operation?
If the ISM (independent switching module) cannot perform a close/trip operation, there are several potential causes: * The ISM is interlocked. Check the ISM interlock state and its actuator coil connection with connector X3 of CM. * CM failure. Check CM LED states. * Mechanical damage of ISM. Replacement of ISM is required.
What to do if none of CM LEDs lights on TAVRIDA ELECTRIC VCB?
If none of the CM LEDs are lit, this could be due to: * Absence of CM power supply. In this case, check the presence of CM power supply, its polarity and voltage level. * Internal fault of CM, which requires replacement of CM.
What does 1 blink of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC VCB?
One blink of the CM “Malfunction“ LED indicates an absence of CM power supply. Check the presence of CM power supply, its polarity and voltage level.
What does 2 blinks of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC Circuit breakers?
Two blinks of the CM “Malfunction“ LED indicates that the ISM cannot be closed or tripped. Check the circuit of the ISM actuator coil connection with connector X3 of CM, and check the state of ISM electrical interlocks.
What does 3 blinks of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC VCB Circuit breakers?
Three blinks of the CM “Malfunction“ LED indicates that the ISM actuator coil circuit is interrupted. Check the circuit of the ISM actuator coil connection with connector X3 of CM and check the state of ISM electrical interlocks.
What does 4 blinks of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC Circuit breakers?
Four blinks of the CM “Malfunction“ LED indicates a short circuit in the ISM actuator coil circuit. Check the circuit of the ISM actuator coil connection with connector X3 of CM, and check the state of ISM electrical interlocks.
What does 5 blinks of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC VCB Circuit breakers?
Five blinks of the CM “Malfunction“ LED indicates a manual trip of ISM and that the ISM is electrically interlocked. Check the ISM and its interlock state.
What does 6 blinks of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC VCB?
Six blinks of the CM “Malfunction“ LED indicates that the CM is out of the temperature range. If the temperature is above the range, stop performing CO operations until the blinks stop. If the temperature is below the range, move the CM into an environment with a higher temperature.
What does 7 blinks of CM “Malfunction“ LED mean for TAVRIDA ELECTRIC Circuit breakers?
Seven blinks of the CM “Malfunction“ LED indicates that the ISM state is open without command from the CM. Check the ISM and its interlock state.
