WBA2503 Air Control Box Tecmark WBA2503 230v SPNO 10 Min. Delay

Manufacturer Part Number: WBA2503

Upon actuation of the PCB mounted air switch, the timer is started and the load relay is energized, applying line voltage to the output terminal. The load relay will de-energize when the time delay period expires or if a second air switch actuation occurs during the time delay period. If the latter occurs, the load relay is immediately de-energized and the timer is reset. This control is equipped for connection to an optional Level Sensor Module which will prohibit load relay actuation until the proper fluid level is satisfied. If the level drops below the sensor activation point during normal operation of the timer, the load relay will immediately de-energize and remain in this state until proper level is reached.
