to a GSR DI safety relay module configured for automatic restart and also showing an E-Stop
switch connection.
Principle of operation
When the light path on the SC300 safety camera is clear and the input conditions on the
GSR DI safety relay module are valid, the system is ready for switch on and waits for an
input signal/switch on signal. The system’s corresponding logic path is enabled by
pressing and releasing the related restart switch. The related outputs of the GSR DI carry
power. If the input conditions are no longer met, the related outputs of the GSR DI shut
down.
The restart switch/button must be used to restart the system.
