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

4.3 Configuration mode
(edit mode)
On initial commissioning, the device must be adapted (configured)
to the application.
Configuration
• Press the “Mode” button to select the requested parameter.
• Press the “Data” button to set the value.
Exit Configuration menu:
Press “Mode” until “h End”, than press “Data”.
Adjustable parameters:
C active inputs: 001 = both inputs 1 and 2, 002 = only input 1,
003 only input 2
h The holding time (extension of the output signal):
001 = none, 002 =100 ms, 003 = 200 ms, 004 = 500 ms, 005 = 1000 ms
To enter Configuration menu
(see also chapter 4.4):
• Enter diagnostic menu: Press “Mode” and “Data” buttons simultaneously for 2 seconds
→
Status LED flashes orange.
• Press “Mode” repeatedly until “C” and “con” are displayed.
• Press “Data” button, “con” starts flashing.
• Press “Mode” and “Data” buttons simultaneously until “con” stops flashing.
• Release “Mode” and “Data”, “C” starts flashing, both safety outputs open.
