Switchgear with microcontroller for level-dependent control of two submersible pumps with float switch for level measurement. The parameterisation is carried out using DIP switches and potentiometers. For connection to the mains without neutral conductor (3~400 V) only!
Functions
- “Drain” operating mode: For draining sewage chambers in water disposal
- Configurable overload protection
- Thermal motor monitoring
- Pump kick function for 2 sec
- Adjustable follow-up time up to 120 sec
- Pump cycling after every run
- Direction of rotation monitoring
- High water alarm with forced switch-on of the connected pumps
- Fault memory of the last fault
Equipment
- Lockable main switch
- Control panel with buttons
- Display of the current operating or fault conditions via LED
- Configurable electronic motor current monitoring
- Setting of individual functions using DIP switches and potentiometers
- Integrated alarm buzzer, mains-independent via 9 V battery (optionally available as accessory)
Inputs
- 2x digital inputs for float switches (pump on/off)
- 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!
Outputs
- 1x potential-free contact for the collective fault signal (SSM)
- 1x potential-free contact for the high water alarm
Notice: Power supply must be provided by the customer!
Scope of delivery
- Switchgear
- Installation and operating instructions
Configuration
Attention: Signal transmitters are to be provided on-site. Switchgears are not protected against explosions and may only be used outside hazardous areas.
Signal transmitters within hazardous areas must be connected through an intrinsically safe circuit, e.g. a Zener barrier or Ex cut-off relay. The direct connection of pumps within hazardous areas is not possible!
