- 配線 & 操作ガイド
5.1 Standard Terminals
| ターミナル | 説明 |
| A1 | 電源 (+) |
| A2 | 電源 (–) |
| 1 | Common contact |
| 2 | 常閉接点 (ノースカロライナ州) |
| 3 | 常開接点 (いいえ) |
5.2 操作手順
- Connect power (A1, A2) and load (1-2 または 1-3).
- Turn the “Time Steps” knob to select the time range (例えば, 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.
- 選択 & 代替案
6.1 主要な選択パラメータ
- Supply voltage: Choose according to on-site power (220V AC or 110V AC).
- タイミング範囲: Select appropriate range based on control requirements (0.1s-100h).
- 接点定格: 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).
