MS-L-2x4kW-DOL

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.

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!
