4. Persediaan dan Pemasangan
The LC1D12EHE contactor can be mounted on a DIN rail or directly to a panel using screws.
4.1. Pemasangan
Pemasangan Rel DIN:
- Ensure the DIN rail is securely fastened within the enclosure.
- Hook the top edge of the contactor onto the DIN rail.
- Press the bottom of the contactor firmly until it clicks into place.
Pemasangan Panel:
- Identify the mounting holes on the contactor base.
- Mark and drill appropriate holes on the panel surface.
- Secure the contactor using screws of suitable size and length.
4.2. Pendawaian
Refer to the wiring diagram provided with your specific application or system. The contactor features screw clamp terminals for both power and auxiliary connections.
- Power Terminals (1L1, 3L2, 5L3, 2T1, 4T2, 6T3): Connect the main power circuit to these terminals. Ensure correct phase sequence for 3-phase applications.
- Control Coil Terminals (A1, A2): Connect the 48-130VAC/VDC control voltage ke terminal ini.
- Auxiliary Contacts (13 NO, 14 NO, 21 NC, 22 NC): Use these contacts for control circuit interlocking, signaling, or other auxiliary functions.
Always verify all connections are tight and secure before applying power.

Rajah 1: Depan view of the LC1D12EHE Contactor, showing main power terminals (1L1, 3L2, 5L3, 2T1, 4T2, 6T3), auxiliary contacts (13 NO, 14 NO, 21 NC, 22 NC), and coil terminals (A1, A2).
5. Operasi
The TeSys Deca Green contactor is designed for switching electrical loads, primarily motors, in industrial control applications. When the appropriate control voltage (48-130VAC/VDC) is applied to the coil terminals (A1 and A2), the contactor's main contacts close, allowing power to flow to the connected load.
- Memberi tenaga kepada Gegelung: Applying the specified voltage to A1 and A2 will energize the coil, causing the main power contacts (1L1-2T1, 3L2-4T2, 5L3-6T3) to close. Simultaneously, the built-in auxiliary contacts will change state (NO contacts close, NC contacts open).
- Menyahtenagakan Gegelung: Mengeluarkan voltage from A1 and A2 will de-energize the coil, causing the main power contacts to open and the auxiliary contacts to return to their original state.
Ensure the control circuit is properly designed and protected to prevent unintended operation or damage.
6. Penyelenggaraan
Regular inspection and maintenance are crucial for ensuring the long-term reliability and safe operation of the contactor.
- Pemutusan Kuasa: Always disconnect all power to the contactor and associated circuits before performing any maintenance.
- Pemeriksaan Visual: Periksa penyentuh secara berkala untuk tanda-tanda haus, kerosakan, perubahan warna atau sambungan yang longgar. Periksa pengumpulan habuk atau serpihan.
- Keketatan Terminal: Verify that all screw clamp terminals are securely tightened. Loose connections can lead to overheating and component failure.
- Keadaan Sentuhan: While the contactor is de-energized, visually inspect the main contacts for excessive pitting or erosion. Severely worn contacts may require replacement of the contactor.
- Pembersihan: Use a dry, lint-free cloth to clean the exterior of the contactor. Do not use solvents or abrasive cleaners.
Jangan cuba membaiki komponen dalaman. Jika penyentuh rosak atau tidak berfungsi, gantikan unit.
