- Wiring & Operation Guide
5.1 Standard Terminals
| Terminal | คำอธิบาย |
| A1 | แหล่งจ่ายไฟ (+) |
| A2 | แหล่งจ่ายไฟ (–) |
| 1 | Common contact |
| 2 | Normally closed contact (เอ็นซี) |
| 3 | Normally open contact (เลขที่) |
5.2 ขั้นตอนการดำเนินงาน
- Connect power (A1, A2) and load (1-2 หรือ 1-3).
- Turn the “Time Steps” knob to select the time range (เช่น, 10-minute range).
- Turn the “t” knob to set the precise time value (0.1-10 times the range value).
- Apply power; the time relay starts operating, and contacts actuate when the set time is reached.
- Selection & Alternatives
6.1 Key Selection Parameters
- แรงดันไฟฟ้า: Choose according to on-site power (220V AC or 110V AC).
- Timing range: Select appropriate range based on control requirements (0.1s-100h).
- Contact rating: Ensure rated current ≥ load current (5A for resistive loads; derate for inductive loads).
- Operating mode: Select on-delay or off-delay based on control logic (ERV-08M).
