Design a Control-Reliable Safety System
In any risk
reduction plan, it is necessary to minimize the level of risk as far
as is practicable. This requirement is specified in all
international safety standard and strictly adhere to.
A control-reliable
safety system is a part of total machine control which prevents a
hazardous condition from occurring. It can be a separate dedicated
system or it may be integrated with the normal machine control
system.
An Unsafe Control
Circuit
Safety is unsure if faults happen:
• Short circuit/earth fault
• Break in wiring
• Switch contact/motor contactor weld
• Switch manipulation
A Control-Reliable
Safety Circuit
Safety is ensured because of fault detection and
prevention.
