introduction
This section deals with electrical emergency brakes with mechanical latching and electrical and mechanical requirements for the following international standards.
Added.
---ISO 13850, which specifies requirements for the emergency braking function of the machine (in any form of energy used);
---IEC 60204-1, which sets additional requirements for emergency braking functions implemented by the electrical equipment of the machine;
---IEC 60947-5-1, which specifies the electrical characteristics of electromechanical control circuit appliances.
Low voltage switchgear and control equipment
Part 5-5. Control circuit electrical and switching components
Electrical emergency brake device with mechanical latch function
1 Scope
This part of GB/T 14048 specifies the electrical and mechanical structure and test of the emergency brake device with mechanical latching function.
Body requirements.
This section applies to electrical control circuit appliances and switching components that issue emergency brake signals. These appliances can come with their own casings or
Manufacturer's manual installation.
This section does not apply to.
---Emergency braking device for non-electrical control circuits (such as hydraulic and pneumatic);
---Emergency brakes without mechanical latching.
The emergency brake can also be used to provide an emergency cut-off function.
Since the noise generated by the electrical emergency brake device with mechanical latching does not pose a risk, this section does not involve any
Specific requirements regarding noise.
Note. See also 9.2.5.4 of IEC 60204-1.2005.
