the economical alternative Replacement for STRATE 1DF2 and 2DF2 pump controllers suitable for connection to all STRATE fill level recording systems: contact-based or contactless the 2DF2 plus also handles dual level measurement: Sensor/pilot tube and sensor/contactor for outstanding operational reliability the current level and operating hours are always shown on the display

2DFmaster AWAcontrol control system for STRATE sewage pumping stations with two pumps each and an installed overall motor rating of 0.75 kW to 75 kW each. Particularly suitable for building services engineering and municipal applications (twin systems), offers outstanding ease of use and functionality of the AWAmaster technology also for pumping capacities over 4 kW. LCD plain text display Thermal and electrical motor monitoring Manual – 0 – Automatic functions Pump switch-off through switch-off point with run-on time Acknowledgement button Electronic monitoring of the motor current Forced switch-on, switchover and alternation of pumps Internal acoustic alarm Collective fault message potential-free and potential-bound Backwater alarm potential-free All settings and fault messages retained after power failure Operating hours counter High resistance to interference Simple operation Level recorded either by internal pressure transducer, external 4 – 20 mA probe or float switch

Compact control systems with micro-processor technology for controlling STRATE sewage pumping stations with two pumps each and an installed motor rating of up to 5,5 kW per pump. Particularly suitable for building services engineering (twin systems) and do not require a separate control cabinet. Compact control system AWAmaster 2 in plastic housing Ready for connection with 1.5 m cable and CEE plug 16 A, 5-pole Parallel operation of both pumps to cope with increased sewage volume (e.g. during heavy rain) LCD plain text display Thermal and electrical monitoring of the motors Manual – 0 – Automatic functions Pump switch-off through switch-off point with run-on time Acknowledgement button Electronic monitoring of the motor current Forced switch-on, switchover and alternation of pumps Variable graduated start-up (switch-on delay) Internal acoustic alarm Collective fault message potential-free and potential-bound Backwater alarm potential-free
