  • Page 6 The operation of the second channel contacts (25-28) is similar to the operation of contacts 15-18 described in Table 3. Table 3 On-delay. After the relay is energized, a count- down (T) is started. Once the countdown is fin- ished, relay is switched on (contacts 15-18 close) and remains on as long as the relay is energized.
  • Page 7 Table 3 continued Delay Off (Leading edge) After the relay is ener- gized, it remains in a steady state until a signal (S) is detected. As soon as the signal is detected, contacts 15-16 open, contacts 15-18 close, and the countdown timer (T) is started. Once the countdown is finished, contacts 15-18 open, and contacts 15-16 close.
  • Page 8 Table 3 continued One-shot Bi-stable. After the relay is energized, it remains in a steady state until a signal (S) is detected. As soon as the signal is detected, con- tacts 15-16 open, contacts 15-18 close, and relay remains in this state. As soon as the second signal is detected, contacts 15-18 open, and contacts 15-16 close.
  • Page 9 Table 3 continued Delay On (Leading edge) After relay is energized, it remains in a steady state until a signal (S) is detected and disap- pears.As soon as the signal disappears, con- tacts 15-16 open, contacts 15-18 close, and relay remains in this state.
  • Page 10 Table 3 continued One-shot (T1) / Delay On (T2) After the relay is energized, contacts 15-18 close, and contacts 15-16 open and remain in this state for the dura- tion of countdown (T1). Once the countdown (T1) is finished, contacts 15-18 open, contacts 15-16 close, and a new countdown (T2) is started.

  • Page 12 Table 3 continued Alternating pulse generation. After the relay is energized, it remains in a steady state until a signal (S) is detected. As soon as the signal is detected, contacts 15-16 open, con- tacts 15-18 close, and the countdown timer (T1) is started.
  • Page 13 Table 3 continued Delayed On T2 Leading Edge ≥T1 After the relay is energized, it remains in a steady state until a signal (S) is detected.. After the sig- nal S is detected, the countdown (T1) begins. Once the countdown (T1) is finished, contacts 15-16 open, contacts 15-18 close, and a new countdown (T2) is started.
