Omron STI's New G9SX-GS Safety Guard Switching Unit Protects Operators and Machines while Increasing Machine Productivity
The manual switching function is ideal for applications that require limited machine access for operations such as maintenance and cleaning. During normal machine operation the door switch monitors the door status and allows the machine to operate so long as the door is closed. When the operator switches to maintenance mode the door switch is disabled and an enabling switch is put into the safety circuit. The enabling switch allows the machine to continue to safely operate so long as the operator continues to hold the enabling switch in the 'enabled' position. Should the operator release the enabling switch to the 'disabled' position, the machine will stop to prevent danger to the operator.
G9SX-GS devices are compliant with IEC/EN 61508 (SIL3), IEC/EN 62061 (SIL3) and EN 954-1 (category 4).
