Input card defective?

To check out if a misconduct originates from an input card, you have the possibility to mute/deactivate single input cards.

To do this, please connect static 24V at IN2, so the monitoring on  this card is deactivated 

See also page 12 off „Disable monitoring - If one monitoring system should be disabled, this could be done by connecting the input IN2 to 24V“
