4. Instal·lació
4.1 Esquema de cablejat
Figura 2: Esquena view of the TM619 with wiring terminals and specifications.
The TM619 timer switch features 5 terminals for connection. Refer to the diagram on the back of the unit and Figure 2 for proper wiring. Ensure all connections are secure and comply with local electrical codes.
- Terminals 1 i 2: Power Input (24VDC). These terminals supply power to the timer itself. Ensure a continuous 24VDC supply to keep the timer operational and maintain its internal clock and programs.
- Terminals 3, 4, 5: Switching Contact (Output). This is a single changeover switch (SPDT - Single Pole Double Throw) with 1 Normally Open (NO) and 1 Normally Closed (NC) contact.
- Terminal 3: Comú (COM)
- Terminal 4: Normally Open (NO) - Contact closes when the timer is ON.
- Terminal 5: Normally Closed (NC) - Contact opens when the timer is ON.
The output contacts are rated for 16A at 250VAC (50/60Hz) for resistive loads, and 1HP at 125VAC, 2HP at 250VAC for inductive loads. For DC loads, it supports 20A at 30VDC.
4.2 Muntatge
The TM619 is designed for panel mounting. It features mounting holes on its casing for secure attachment to a control panel or enclosure. Ensure adequate ventilation around the unit to prevent overheating.
5. Configuració i programació
Before programming, ensure the timer is powered. The built-in battery will charge when the unit is powered, maintaining settings during power interruptions.
