3.7 Input Circuits

This page configures the usage of the input circuit's provided by the DEICE-Controller. The DEICE-Controller monitors 48 general purpose inputs. Each input may be configured as a simple state monitor, signaling its state as ON/OFF, or as alarm input signaling it' state as OK/FLT.

The following properties may be set for each individual input:

• Type --- Defines the main purpose / type of the input:

  • UNUSED --- The input is not connected / not used.
  • INPUT --- The input is used for general purpose state monitoring. It reports its state as ON/ OFF.
  • ALARM --- The input is used for alarm monitoring. It reports its state as OK / FLT.
  • LALARM --- The input is used for latched alarm monitoring. It reports its state as OK / FLT.

• Name --- When you activate an input at the 'Type' setting, the DEICE-Controller names this input as 'Ixx'. You may name the input in a more meaningful way by entering a circuit name at this place.

• Polarity --- 'NORMAL' polarity signals 'ON' or 'FLT' for a closed contact, 'INVERTED' polarity reverses this behavior.

• Delay --- If this parameter is set to a non-zero value, the DEICE-Controller requires the input signal to be stable for at least the given time before a new state is signalled. You may use the delay to prevent short fault 'spikes' from being signaled.
