Page 4: Safety Standards
Operating instructions 3 SAFETY STANDARDS It is recommended to follow the instructions below in order to avoid damage to the system, the device, or injury to the technician, or to other people during operation. Throughout this manual, the following symbols are used to indicate the possible danger levels if the installation instructions are not followed. - Page 5 PCP VOLUMETRIC PUMP DRIVE DANGER Read the following instructions in their entirety before checking the products at the time of delivery, before transport and storage, installation, wiring, operation, inspection, and disposal. Make sure you have correctly connected the connectors and fixed the cables.
- Page 6 Operating instructions REQUIRED During installation, protections must be provided for over-currents, for electricity leakage, for over-temperatures, as well as emergency stop devices. Failure, in the absence of protection, can cause electrical shock, injury or fire. Strictly follow the instructions and procedures contained in this manual to verify the correct installation.
- Page 7 Failure to observe this warning can cause deterioration of the internal components with consequent fires or malfunctions. DAV Tech products are precision equipment. Avoid violent shocks during transportation, installation, and operation. Failure to observe this warning can cause malfunctions.
- Page 8 Operating instructions Securely connect the power terminals. Use cables with a section suitable for their use. Failure to observe this warning can cause a fire. Keep the power and signal lines at a distance of at least 300mm. Use twisted pairs or shielded cables.
- Page 9 • This manual is subject to change due to product improvements, specification changes or improvements to the manual. • DAV Tech srl is not responsible for damage to things and / or people caused by incorrect installations and / or unauthorized modifications of the product.

- Page 12 Operating instructions 4.1 Panel installation If installed inside an electrical panel, leave a free space of at least 50 mm around the module in case of the installation of a single drive. If more drives are installed, respect the minimum space, as shown in the following figure, between two contiguous drives, in order to guarantee air flow and cooling of the modules.
- Page 13 The trend of the thermal dissipation in relation to the supplied current is shown below. Watts Amperes The electric current required to control the PCP pumps is 2.5 A. 4.3 Electrical connections Below is the trend of the thermal dissipation in relation to the supplied current.
- Page 14 The maximum absorption for a PCP pump is about 2.5 A while the drive logic is about 200-300mA.
- Page 15 PCP VOLUMETRIC PUMP DRIVE To reduce EMI disturbances, it is required to install a ferrite filter at a maximum distance of 150 mm from the drive on the motor cable. The filter is composed of low-grade ferrite which has high radio frequency losses; in this way the filter works as a high impedance at those frequencies.

Operating instructions ATTENTION The digital outputs are protected against overloads (Max 500mA) and short-circuits; in case of overload the output will switch off until the anomaly is removed. If inductive loads, such as relays, solenoid valves, etc. have to be driven, connect a flyback diode in parallel to the load. - Page 17 PCP VOLUMETRIC PUMP DRIVE 2 3 4 5 6 7 8 9 Components identification 2 3 4 5 6 7 8 9 Power supply and motor Service input connector (M2) connector (M1) PIN Signal name Description PIN Signal name Description...
