3. Karatteristiċi tal-prodott

The MARSTEK Triple Power 63A ATS offers a range of features designed for reliable power management:

• Triple-Source Automatic Switching: Seamlessly transfers loads between Primary, Backup 1, and Backup 2 power sources during outages, voltage sags/surges, or irregularities. Automatically reverts to the preferred source once stable.
• Built-in Electrical Protection: Safeguards connected equipment with advanced Overvoltage (140V max), Undervoltage (90V min), and Overcurrent (63A max) protection, preventing damage from unstable power.
• Flexible Priority Phase Setting: Designate ANY input (L1/L2/L3) as Primary—optimize for cost, reliability, or grid conditions without fixed "Main" limitations.
• Real-Time LED Voltage Monitoraġġ: Intuitive display shows live voltage levels (e.g., 120V, 108V) for all 3 sources, with instant status indicators for active source, transfer, and faults.
• Quick DIN Rail Installation & Compact Design: Space-saving unit installs in minutes via standard DIN rail mounting, rated for 63A at AC 110V with a 10⁶ mechanical lifespan.

6. Installazzjoni

6.1 Immuntar tal-Ferrovija DIN

The MARSTEK ATS is designed for quick and easy installation on a standard DIN rail.

1. Ensure all power sources are disconnected and verified as de-energized.
2. Align the back panel display of the ATS with the DIN rail.
3. Press the latch located on the bottom of the ATS.
4. Insert the ATS onto the DIN rail.
5. Release the latch to secure the ATS firmly in place. You should hear a "click" sound.

• Terminali tal-Input: Connect your three power sources (e.g., Utility, Generator, Inverter) to L1, L2, and L3 respectively. Connect the neutral lines to the N terminals.
• Terminali tal-ħruġ: Connect your load to the N (Neutral) and L (Line) output terminals.
• Importanti: Ensure correct phase and neutral connections. Incorrect wiring can damage the device or connected equipment.

7. Operazzjoni

7.1 Power-On and Initial State

Once wired and power is applied, the ATS will perform a self-check. The LED display will show the voltage levels of the connected sources. The device will automatically select the primary source (as configured) if it is stable and within acceptable parameters.

7.2 Loġika ta' Swiċċjar Awtomatiku

The ATS continuously monitors the voltage and stability of all three connected power sources. The switching logic is as follows:

• If the designated primary source (L1, L2, or L3) is stable and within acceptable voltage/current limits, the load will be connected to it.
• If the primary source experiences an outage, voltage sag/surge, or overcurrent condition, the ATS will automatically transfer the load to the next available stable backup source (Backup 1, then Backup 2).
• Once the primary source is restored and stabilized, the ATS will automatically revert the load back to the primary source after a configurable delay.

7.3 Aġġustament tal-Parametri

The ATS features a digital adjustment panel for customizing various parameters. Use the 'M' (Menu), 'Up' (Digit+), and 'Down' (Digit-) buttons to navigate and adjust settings.

• Power-on delay time (PE): Time delay before the ATS powers on after initial power application.
• Transfer time/Protection recovery delay time (rE): Delay before switching to a backup source or reverting to primary.
• Overvoltage protection value (oU): Sets the upper voltage limitu.
• Undervoltage protection value (UU): Sets the lower voltage limitu.
• Priority phase (PS): Designate L1, L2, or L3 as the primary power source.
• Overcurrent protection value (oC): Sets the maximum current limit.
• Overcurrent protection action time (CtT): Delay before overcurrent protection trips.
• Continuous overcurrent protection frequency (CC): How often overcurrent protection can trip.

Refer to the on-screen menu for specific navigation and adjustment procedures. Always ensure settings are appropriate for your electrical system and connected loads.

8. Manutenzjoni

The MARSTEK ATS is designed for minimal maintenance. However, regular checks can ensure optimal performance and longevity:

• Spezzjoni Viżwali: Spezzjona l-apparat perjodikament għal kwalunkwe sinjal ta’ ħsara fiżika, konnessjonijiet laxki, jew tibdil fil-kulur.
• Kontrolli tal-Konnessjoni: Ensure all wiring terminals remain tight. Loose connections can lead to overheating and device failure.
• Indafa: Żomm l-apparat ħieles mit-trab u l-fdalijiet. Uża drapp niexef u artab għat-tindif. Tużax prodotti tat-tindif likwidi.
• Test tal-Funzjonalità: If possible and safe to do so, periodically test the automatic transfer function by simulating a power outage on the primary source.

WARNING: Always disconnect power before performing any maintenance or cleaning.
