How it works

In automatic mode, the pumps are switched on and off depending on the water level. Once the first activation point has been reached, pump 1 switches on. Once the second activation point has been reached, pump 2 switches on after the activation delay has elapsed. During operation, a visual indicator appears on the LCD display and the green LED lights up. Once the deactivation point has been reached, both pumps are switched off after the deactivation delay has elapsed. To optimise pump running times, pump cycling is carried out every time the pump is switched off.

An alarm signal is shown on the LCD display in case of a fault. If more than one pump is connected, automatic changeover to a fully-functional pump occurs. Additionally, the internal buzzer can emit an audible alarm signal. Furthermore, the outputs for the collective fault signal (SSM) and individual fault signal (ESM) are activated.

Upon reaching the dry run or high water level, the following occurs depending on the operating mode:

An alarm signal is also shown on the LCD display. Additionally, the internal buzzer can emit an audible alarm signal. Furthermore, the output for the collective fault signal (SSM) is activated.
