4. Instalare
4.1 Schema electrică
Figura 2: Spate 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.
- Terminalele 1 și 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.
- Terminalele 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.
- Terminalul 3: Comun (COM)
- Terminalul 4: Normally Open (NO) - Contact closes when the timer is ON.
- Terminalul 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 Montare
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. Configurare și programare
Before programming, ensure the timer is powered. The built-in battery will charge when the unit is powered, maintaining settings during power interruptions.
Figura 3: Înclinat view of the TM619, highlighting the compact design and button layout.
5.1 Setarea orei și zilei curente
- Țineți apăsat butonul CEAS buton.
- În timp ce ține CEAS, apăsați ZI to set the current day of the week (Mo, Tu, We, Th, Fr, Sa, Su).
- În timp ce ține CEAS, apăsați ORĂ pentru a seta ora curentă (0-23).
- În timp ce ține CEAS, apăsați MIN pentru a seta minutul curent (0-59).
- Eliberați CEAS button. The time and day are now set.
5.2 Programarea timpilor de pornire/oprire
The TM619 allows for up to 16 ON/OFF programs. Each program consists of an ON time and an OFF time.
- Apăsați tasta TIMER Apăsați butonul o dată. Afișajul va afișa „1 ON”.
- Presa ZI to select the day(s) for this ON program. You can choose a single day, specific days (e.g., Mo-Fr), or all 7 days.
- Presa ORĂ pentru a seta ora de pornire dorită.
- Presa MIN pentru a seta minutul de pornire dorit.
- Presa TIMER din nou. Afișajul va afișa „1 OFF”.
- Repeat steps 2-4 to set the OFF day(s), hour, and minute for the first program.
- Presa TIMER pentru a trece la programul următor („2 ON”, „2 OFF” etc.) și repetați procesul pentru maximum 16 programe.
- După setarea tuturor programelor dorite, apăsați butonul CEAS pentru a ieși din modul de programare și a reveni la afișajul orei curente.
Note: If you need to clear a specific program, navigate to that program (e.g., "3 ON") and press the MANUAL button. This will clear the settings for that ON/OFF pair.
5.3 Anulare manuală
The MANUAL Butonul vă permite să anulați temporar sau permanent setările programate.
- Presa MANUAL în mod repetat pentru a parcurge modurile:
- PE: Ieșirea este activă continuu, ignorând programele.
- MAȘINĂ: Timer operates according to programmed settings.
- OPRIT: Ieșirea este permanent OPRITĂ, ignorând programele.
