Operating Modes Explained
- On Delay (M1): Activates the output after a preset delay once power is applied.
- Interval Delay (M2): Keeps the output active for a preset time after power is applied, then deactivates.
- Cyclic Off First (M3): Alternates the output between off and on states in a cyclic manner, starting with the off state.
- Cyclic On First (M4): Alternates the output between on and off states in a cyclic manner, starting with the on state.
- Star-Delta (M5): Facilitates motor starting by switching from star to delta configuration after a preset time.
- Instant & Delayed (M6): Provides immediate activation of one output and delayed activation of another.
- Engine Start (M7): Manages multiple start attempts for engines, with configurable number of attempts and time intervals.
Technical Specifications
- Time Ranges: Selectable ranges include 0.1-1 sec, 1-10 sec, 6-60 sec, 60-600 sec, 0.1-1 hr, 1-10 hr, and 10-100 hr.
- Output Contacts: Two changeover contacts (1 CO + 1 CO).
- Power Consumption: Maximum of 15VA for AC models and 3W for 24V DC models.
- Contact Rating: 5A at 230V AC resistive load.
