The restart command element must be installed outside the hazardous

area in a position where the hazardous area and the entire work area

concerned are clearly visible�

The device may also be installed within the hazardous area since handling

is not required during operation�

When the device is waiting for the restart command, the yellow LED [ENA]

flashes�

Manual operation (circuitry of the inputs Y5 and Y6)

Manual operation is implemented when during initialisation input Y6 is on the

pulsed test signal of Y1 and input Y5 is open�

The start-up delay of 10 seconds is active after each restart command

3�6 Start-up delay)�
