Timing Diagrams for Predefined Timer Operating Modes
NOTE: Input A is shown as a Sourcing input (active high). If a Sinking input (active low) is used, the logic levels for Input A would be inverted.

The input signal must be wired to both the Input A and
User Input 1 terminals. The Timer Input plug jumper and
the User Input plug jumper must both be set to the
same position (either both SNK or both SRC).
The input signal must be wired to both the Input A and
User Input 1 terminals. The Timer Input plug jumper and
the User Input plug jumper must be set to opposite
positions (one SNK, one SRC) and the Input signal must
be a current sinking type (i.e. pulls input to common).
