Construction
Microprocessor-controlled switchgear for level-dependent control of one, two or three submersible pumps with float switch for level measurement. The parametrization is carried out using dip switches and potentiometers.
Inputs
1x…2x digital inputs* for float switch (pump on/off)
1x digital input for high water signal with float switch (high water alarm)
1x…2x inputs* for thermal winding 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 (for switchgear for 2 pumps)
*Depending on the number of pumps that can be connected.
Configuration
Caution! 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. The direct connection of pumps within potentially explosive atmospheres is not possible!
