4. 설정 및 설치

4.1 장착

The GT3A-3AD24 is designed for plug-in mounting into a compatible 8-pin relay socket (sold separately). Ensure the socket is securely mounted in a control panel or enclosure, away from excessive heat or vibration.

1. Select a suitable mounting location for the relay socket.
2. Secure the relay socket using appropriate fasteners.
3. Align the pins of the GT3A-3AD24 relay with the corresponding holes in the socket and gently push the relay into place until it is fully seated.

4.2 배선

중요한: Disconnect all power before performing any wiring. Refer to the wiring diagram typically found on the relay's housing or in the socket's documentation for precise pin assignments. The following describes a typical 8-pin DPDT timer relay wiring configuration:

• Power Supply (Coil): Connect the 24VAC/VDC supply to the designated coil terminals (e.g., pins 2 and 7 for many 8-pin relays). Ensure correct polarity if using DC.
• 공통 연락처: The DPDT configuration provides two independent sets of contacts. Each set has a common terminal. Connect your load's power source to these common terminals (e.g., pins 1 and 8).
• 일반적으로 열려 있는(NO) 접점: When the timer is active and timed out, these contacts close. Connect the load to the NO terminals (e.g., pins 3 and 6) and the common terminals.
• 일반적으로 닫힘(NC) 접점: When the timer is inactive, these contacts are closed. They open when the timer is active and timed out. Connect the load to the NC terminals (e.g., pins 4 and 5) and the common terminals if an inverse operation is required.

5. 사용 설명서

The GT3A-3AD24 operates as a delayed timer relay. Upon application of power to the coil, the timing sequence begins. After the set time delay, the output contacts will switch state.

5.1 시간 지연 설정

The timer relay typically features two rotary dials on its front face for setting the time delay:

• Time Range Selector: This dial selects the overall timing range (e.g., 0.1s-1s, 1s-10s, 1m-10m, 1h-10h, up to 180 hours).
• Time Multiplier/Value Selector: This dial sets the specific time value within the selected range (e.g., if the range is 0.1s-1s, this dial might set 0.5s).

To set the desired time delay:

1. 회전하다 Time Range Selector to the appropriate range that encompasses your desired delay.
2. 회전하다 Time Multiplier/Value Selector to the specific time value within that range.

예를 들어ample, to set a 5-minute delay, you might select the "1m-10m" range and then set the multiplier to "5".

5.2 작업 순서

1. Apply 24VAC/VDC power to the relay coil.
2. The internal timer begins counting. During this period, the Normally Closed (NC) contacts remain closed, and Normally Open (NO) contacts remain open.
3. Upon completion of the set time delay, the output contacts switch: NC contacts open, and NO contacts close.
4. The contacts remain in this switched state as long as power is applied to the coil.
5. Removing power from the coil resets the timer, and the contacts return to their original (unenergized) state.

6. 유지관리

The Idec GT3A-3AD24 Timer Relay is designed for long-term, reliable operation with minimal maintenance.

• 정기 검사: Regularly inspect the relay and its socket for any signs of damage, discoloration, loose connections, or excessive dust accumulation.
• 청소: If necessary, gently clean the exterior of the relay with a soft, dry cloth. Do not use solvents or abrasive cleaners. Ensure power is disconnected before cleaning.
• 환경 조건: 조기 고장을 방지하려면 작동 환경이 지정된 온도 및 습도 범위 내에 유지되도록 하세요.
