Local operation
Hardware settings / configuration
Any device settings using the DIP switch must be made when the device is de-
energized.
Direction of action
At the device, the direction of action (operating or closed circuit current behavior) can be
selected and line fault detection can be enabled or disabled via DIP switches.
DIP switch 1 = channel 1; DIP switch 3 = channel 2
All DIP switches are set to the "I" position when the device is delivered from the factory:
• I = normal phase (operating current behavior)
• II = inverse phase (closed circuit current behavior)
DIP switch 1:
• DIP switch position I = normal function: in the event of a 0-signal at the input, the relay
output (changeover) switches to the "non-conducting" state (NO contact is open) or
"conducting" state (NC contact is closed).
• DIP switch position II = inverse function: in the event of a 1-signal at the input, the relay
output (changeover) switches to the "non-conducting" state (NO contact is open) or
"conducting" state (NC contact is closed).
Line fault detection
DIP switch 2 = channel 1; DIP switch 4 = channel 2
I = line fault detection switched off -
not permitted for safety-oriented applications!
II = line fault detection switched on
If a line fault occurs, the relay is de-energized and the red LED "LF" flashes (NE 44).
