    CapDRIVE can be installed directly on the fan cover of the motor or mounted on the wall. Motor mounting kit In this application CapDRIVE is cooled by the motor fan. Motor kit (available upon request) allows a solid coupling of the two units and it is composed of:...
  • Page 11 Make sure to properly attach the grid of the auxiliary cooling fan. Make sure to remove the auxiliary cooling fan if CapDRIVE is coupled to a motor. Failure to do so creates a high risk of overheating the motor and CapDRIVE unit.

    If the set-pressure of the system is 60 psi, the pre-charge pressure of the tank should be 48 psi 5.1.2 Pressure sensor CapDRIVE requires a pressure sensor with a linear output signal within the range 4 – 20 mA. The pressure transducer can be powered by any range of DC Voltage which includes the value 15 V dc.

    Screen is a back-lit LCD displaying 2 rows of 16 digits each. Alarms are indicated by an audible signal. Initial configuration When CapDRIVE is switched on for the first time, the initial setting menu is displayed for the initial setting of parameters to configure pump characteristics, pressure sensor range, and system characteristics.

    A first method consists of a single pump driven directly by CapDRIVE and another 1 or 2 pumps directly connected to the mains DOL (Direct On Line); DOL pumps are controlled by CapDRIVE and connected to the mains through 1 or 2 contactors.

    2. If pressure at the point 2 is (set value – delta control), CapDRIVE will run the DOL by relay DOL1. The DOL pump will run at its nominal speed while the pump 1 will drop it speed equal to the P1 pattern to maintain set pressure.

  • Page 27: Combo Function

    To achieve the COMBO function in a system consisting of several interconnected CapDRIVEs, use a pressure sensor connected to each CapDRIVE. The value of the set pressure is communicated to the slaves via the serial port. To prevent the shutdown of the system due to pressure sensor failure, connecting a 2nd pressure sensor to the CapDRIVE; make sure that the two pressure sensors are identical.
