10 Timing Functions
The FCT18-N offers comprehensive timing solutions with 10 distinct functions. Select a function to view its detailed operation:
A: Power On-Delay
Sequence:
- Power(Un) applied – timing starts
- After preset time (T) – output (R) closes
- Output (R) remains closed while power is present
- Output (R) opens immediately when power is removed
As: On-Delay with Control Signal
Sequence:
- Control signal(S) applied –timing starts
- After preset time (T) – output(R) closes
- Output remains closed until next control signal(S) applied
- Control signal can be shorter or longer than T
Aw: On-Delay with Summation Control
Sequence:
- Control signal(S) applied – accumulation starts
- Control signal(S) removed – accumulation pauses
- When accumulated time reaches preset time (T) – output closes
B: Interval
Sequence:
- Power(Un) applied – output (R) closes immediately
- Timing starts simultaneously
- After preset time (T) – output(R) opens
- Output (R) remains open while power is present
Bs: Single Interval with Control Signal
Sequence:
- Control signal(S) applied – output (R) closed and timing starts
- After preset time (T) – output(R) opens
- Output remains open until next control signal(S) applied
- Control signal can be shorter or longer than T
Bw: Off-Delay with Summation Control
Sequence:
- Power(Un) applied – output(R) closes immediately
- Control signal(S) applied – accumulation starts
- Control signal(S) removed – accumulation pauses
- When accumulated time reaches preset time (T) – output opens
Cs: Symmetrical Flashing (Starting Off)
Sequence:
- Control signal(S) applied – output (R) starts in open state
- After preset time (T) – output switches to closed state
- After preset time (T) – output switches to open state
Ds: Symmetrical Flashing (Starting On)
Sequence:
- Control signal(S)applied – output (R) starts in closed state
- After preset time (T) – output switches to open state
- After preset time (T) – output switches to closed state
Fe: Double Interval with Control Signal
Sequence:
- Control signal(S) applied – output(R) closes and timing starts
- After preset time (T) – output(R) opens
- Output(R) closes again when control signal(S) removed
- After preset time (T) – output(R) opens
Js: Pulse Delayed Relay (1s Fixed)
Sequence:
- Control signal(S) applied – timing starts
- After preset time (T) – output(R) closes for1s
- Output(R) opens automatically after 1s
- Output(R) remains open until next control signal
