Microprocessor-controlled switchgear for level-dependent control of two submersible pumps with analogue or digital signal transmitters. Individual parameters are entered via symbol-based menu navigation and an operating button.
Functions
- Three different operating modes for a broad field of application:
- “Drain” operating mode: For draining sewage chambers
- “Fill” operating mode: For filling water tanks and rainwater storage tanks
- Configurable overload protection
- Thermal motor monitoring
- Pump kick function
- Adjustable follow-up time
- Automatic pump alteration
- Service life optimisation
- Standby pump
- Automatic fault-actuated switchover
- Direction of rotation monitoring
- High water alarm with forced switch-on of the connected pumps
- Dry-running protection
- Fault memory for 16 error messages including the type of fault
- Maintenance monitoring
Equipment
- Display of the current operating status and data, as well as faults, using the LCD display and LEDs
- Elapsed time indicator
- Symbol-based menu navigation
- Configuration of operating parameters and operation via operating button
- Main switch
- Motor protection switch in the “DOL” version
- Fuse and motor protection relay in the “SD” version
- Operating mode selection switch per pump: Emergency/test mode, off, automatic mode
- Remote access via ModBus RTU, BACnet and optionally GSM
Inputs
- 1x analogue precision input 4 – 20 mA for level control with level sensor
- 3x digital inputs for level control with float switch
- 1x digital input for low water level with float switch (dry-running protection)
- 1x digital input for high water signal with float switch (high water alarm)
- 2x inputs for thermal winding monitoring for bimetal or PTC temperature sensor
- 2x inputs for connecting moisture sensors (e.g.: Motor compartment leakage or sealing chamber monitoring)
- 1x digital input for External On/Off for remote activation and deactivation of automatic mode
Outputs
- 1x potential-free contact* for the collective run signal (SBM)
- 1x potential-free contact* for the collective fault signal (SSM)
- 1x potential-free contact* for the high water alarm
- 1x potential-free contact* as a signal to start a pump-dependent submersible mixer (when idle)
- 1x analogue output 0-10 V for the output of the actual level value
*NOTICE: Power supply must be provided by the customer!

Configuration
Attention: Signal transmitters are to be provided on-site. Switchgears are not protected against explosions and may only be used outside potentially explosive atmospheres.
Signal transmitters within potentially explosive atmospheres must be connected through an intrinsically safe circuit, e.g. breakdown barrier or Ex cut-off relay.
Direct connection of pumps and/or signal transmitters is not possible within potentially explosive atmospheres!
