Key to the designation
Code DescriptionCervomatic Type seriesE Single-phase ACD Three-phase currentP Electrical protection.2 Product version
Function
Ensures gentle system operation by:
▪ Pressure-dependent pump start
▪ Pressure-dependent or flow-dependent stop of the pump
▪ Integrated dry running protection
▪ Integrated overload protection
Operating modes
The unit offers two different operating modes which can beselected during parameterisation:
On/off mode:
▪ The pump set is started when the pressure in the pipedrops
▪ The pump set is stopped when flow in the pipe isinterrupted
Pressure-dependent mode:
▪ The pump set is started when the pressure in the pipedrops
▪ The pump set is stopped when the set pressure in the pipeis exceeded
Further functions:
▪ Integrated dry running protection of the pump
▪ Integrated overload protection
The lift check valve required for pressure maintenance isnot integrated in the automatic control unit. It must beinstalled in the pipe in addition. (⇨ Page 6)
Pressure curve
The start pressure is set to 3 bar at the factory and can bedecreased to 1 bar or increased to 6.5 bar if necessary. For further information, refer to the operating manual.

Product benefits
▪ The pump is started and stopped automatically bysimultaneous monitoring of pressure and flow rate.
▪ Constant pressure depending on the flow rate bysimultaneous monitoring of pressure and flow rate
▪ Dry-running protection by stopping the motor
▪ Digital indication of (actual and set) pressure
▪ Extremely straightforward menu-controlled setting ofparameters
▪ Pressure-dependent pump start
▪ Pressure-dependent or flow-dependent stop of the pump

1) The pump set is stopped when the actual flow is lower than the minimum flow.2) The control unit must be protected at all times against excess pressure (incl. system-induced surge pressures) exceeding the
permissible maximum burst pressure of pB = 40 bar. If in doubt about the maximum suction-side pressure, either add asafety margin of 5 bar to the nominal pressure, or install a pressure reducer between the pump set and the unit or on thepump set's suction side. In addition, a lift check valve must be installed on the pump set's suction side.
