3.7 Electrical safety

SYIL 7 Series machines contain a range of electrical components that must be properly configured and monitored to ensure a safe working environment.

This section provides important electrical safety considerations and instructions for preventing potential electrical hazards.

3.7.1 Electrical hazards and prevention measures

The human body is highly prone to harm from electricity, and the risk of injury or death increases with voltage levels. While people have suffered fatal accidents from as little as 35 volts, many mistakenly believe they can withstand contact with 100 volts or more.

Though the human body has strong capacity for resisting electrical currents, even low current levels can have a significant impact. The following chart compares different current levels and their impact on the human body:

Current Levels and Impacts
Current Impact on the Human Body Current Impact on the Human Body
Less than 1mA Feeling of weakness and tingling Higher than 50mA Pain and physical injury
Less than 5mA Painful shock Higher than 100mA Fatal injury
10~20mA Pain accompanied by uncontrollable muscular spasms    

3.7.2 Overcurrent relays

When the voltage in an electrical circuit exceeds its rated value, overcurrent relays can limit the current and protect the circuit, making their installation in the machine’s electrical system essential.

Overcurrent relays can be categorized as electric relays, thermal inductance relays, and magnetic inductance relays. Among these types, thermal inductance relays are used most widely.

Thermal inductance overcurrent relays are manufactured with dual-layer metal plates. When the current exceeds the circuit’s rated value, the dual-layer metal board will receive an electrical signal to shut down the current due to overheating.

Thermal inductance overcurrent relays come in several varieties, as shown in the following comparison chart:

Overcurrent Relays
Type Description
Direct heating Directly conducts the current to the dual-layer metal board, with a high sensitivity to movements; however, its resistance level results in some loss of current.
Semi-indirect Features a dual-layer metal board with asbestos insulation and thermal component coils; one side of the thermal component connects to the dual-layer metal board, enabling it to conduct the current.
Thermal release Thermal release Does not transmit current signals to the dual-layer metal board; instead transmits signals to thermal components to generate activation gradually.

3.7.3 Switch control faults and possible diagnosis
