Wiring mandatory
Connected sensors with a terminating resistor of 8.2 kOhm are monito-
red for a change in current.
In the idle mode
• all safety outputs are conductive
• the LED lights up green
• both dots on the display flash
When one or more sensors are
actuated
• the total resistance of the sensor system drops towards zero ohm
• the defined switching threshold is not reached anymore
• the corresponding Safety output opens
• the LED lights up orange, P appears on the display
In the event of a
fault
in the sensor circuit (for example cable breakage)
• the total resistance of the sensor system increases
• the defined switching threshold is exceeded
•
both
Safety outputs open
• the LED lights up red, E appears on the display

Function test
• Press sensor 1, check LED (orange), display (P
,
1). Check if output 1 is open.
• Release sensor
• If present, press sensor 2, check LED, display (P
, 2). Check if output 2 is open.
• Release sensor
After successful testing, the system is ready for operation.
