NOTICE!
Only switch the DIP switch when the device is de-energized.
By default upon delivery, all DIP switches are in the "I" position.
4.1 Effective direction
Switch DIP 1 = channel 1, DIP 3 = channel 2
The effective direction is set using the DIP switch DIP 1 (for channel 1) and DIP 3 (for channel 3).
4.2 Line fault detection
Switch DIP 2 = channel 1, DIP 4 = channel 2
The line fault detection is set using the switch DIP 2 (for channel 1) and DIP 4 (for channel 2).
If line fault detection is enabled, the relay is de-energized when there is an interruption or short-circuit of
the line to the sensor, meaning that the output is put into the safe, not-conductive state.
The red LED (LF) flashes (NAMUR NE 44).
The response range according to EN 60947-5-6 for the line fault report:
(7) DIP switch
Channel 2 Channel 2
DIP 1 DIP 3 normal phase (I)
DIP 1 DIP 3 inverse phase (II)
Relay output normal phase (I) inverse phase (II)
switched if I > 2.1 mA I < 1.2 mA
in rest position if I < 1.2 mA I > 2.1 mA
I = Line fault detection disabled.
Not admissible for safety-related applications!
II = Line fault detection enabled.
Line break 0.05 mA < I
IN
< 0.35 mA
Short-circuit 100 Ω < R
Sensor
< 360 Ω
