Microcontroller-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
- Two 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 10 error messages including the type of fault
- Operating mode “Ex” for loading preset values for “Ex” applications (please note information given under “Configuration”!)
Equipment
- Display of the current operating status and data, as well as faults via the LCD display and LEDs
- Symbol-based menu navigation
- Configuration of operating parameters and operation via operating button
- Remote access via ModBus
- Integrated alarm buzzer
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 protection monitoring with bimetallic temperature sensor - connection of PTC sensors is not possible!
- 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 individual run signal (EBM) per pump
- 1x potential-free contact* for the individual fault signal (ESM) per pump
- 1x 24 VDC output for connecting an external alarm signal
- 1x analogue output 0-10 V for the output of the actual level value
*Note: Power supply must be provided by the customer!
Configuration
- Signal transmitter 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. Zener barrier or Ex cut-off relay.
- Pumps within potentially explosive atmospheres can be directly connected.
