Operation with a defective level sensor

If the level sensor does not transfer a measured value (e.g. due to wire break, defective sensor), all pumps are switched off. Furthermore, the fault signal LED lights up and the collective fault signal is activated.

Emergency operation

• Operating mode “drain”: High water level
• If the high water level is performed by a separate float switch, the system can continue running in emergency operation. The activation and deactivation points are defined by the hysteresis of the float switch.
• Operating mode “fill”: Min. water level
• If the min. water level is monitored by a separate float switch, the system can continue running in emergency operation. The activation and deactivation points are defined by the hysteresis of the float switch.
