The MARSTEK transfer switch offers both automatic and manual operation modes.
Ipo Aifọwọyi

In automatic mode, the switch prioritizes the primary power source (L1). If L1 fails or experiences voltage fluctuations (undervoltage tabi overvoltage), the switch will automatically transfer the load to the backup power source (L2). When L1 is restored and stable, the switch will automatically transfer the load back to L1.
Ipo Afowoyi

The transfer switch can be manually operated using the buttons on the front panel.
- To close L1: Press the button labeled "L1" (often indicated by an up arrow or similar icon). Press again to open L1.
- To close L2: Press the button labeled "L2" (often indicated by a down arrow or similar icon). Press again to open L2.
In manual mode, the automatic transfer function is overridden. Ensure you understand the implications of manual switching before use.
LED Display and Indicators
The LED display provides real-time information about the system status.
- The main display shows voltage readings for the active power source.
- L1: Indicates L1 output is active.
- L2: Indicates L2 output is active.
