Page 4: Health And Safety
HEALTH AND SAFETY The pump must be operated ONLY by authorized and trained technical personnel. All instructions and prescriptions in the technical manual must be strictly followed. Failure to follow these instructions can result in serious damages to the equipment and, in extreme cases, to people. - Page 5 Risk of electric shock! If the pump housing is damaged, immediately unplug the pump and power it again only after a proper repair by an authorized technician. Attention to dosed chemicals! Before any operation on the pump, discharge the liquid from the pump head and pipes.

Page 11: Electrical Connections
ELECTRICAL CONNECTIONS The pump is supplied with prewired power cable and connectors for the available inputs / outputs, depending on the desired configuration. Below is an indicative diagram of the arrangement of the connectors and pin-out of the M8 axial connector, used for pump wiring. - Page 12 FLW Connector – Input for Injection Flow Control (optional) Optional input, available on axial M8 connector, for the control of injected liquid, not to be confused with the control of water flow to the sensor. It allows monitoring the actual injection (passage of liquid) at each magnet pulse.

Page 18: Configuration
CONFIGURATION The PROXIMA PSP pumps feature two configuration levels: standard and advanced. The standard configuration is normally accessed by the end user, for editing a few parameters, as the adjustment thresholds, dosing frequency and display language. The advanced configuration instead allows to change all parameters and is normally protected by a password to prevent incorrect settings by unauthorized personnel. -
Page 19: List Of Parameters
List of Parameters In this section you can find the full list of configuration parameters, divided per pump version. The parameter P01 sets the operation mode and determines the parameters P04, P06…P11, while all the remaining parameters are common for all models. It is recommended to fill the last column with the values set for your specific application. -

- Page 23 unsuccessfully, the alarm remains active and, therefore, a user intervention is required to evaluate and solve the problem. Warning! The self-priming function is potentially hazardous! For example, in case of breakage or simply disconnection of the flow control while the pump works perfectly, the volume of 100 injections will be dosed in the system in less than one minute.
- Page 24 has been successfully completed. If, instead, the threshold is not reached within the set time, the pump stops dosing and displays the error message “Max dosing”. This condition may be caused, for example, by an under-sizing of the pump with respect to the system needs, by the dosage of a too diluted product, by empty injections due to loss of priming, etc.
- Page 25 PARAMETER 42 SERIAL LINE TYPE If the pump is provided with the “serial output” option, this parameter (and the next one) allows to set the operating mode and rate of the serial line. You can choose between Ascii communication (no protocol) and Modbus RTU protocol.

Page 30: Serial Line (Optional)
SERIAL LINE (optional) The pump may feature an RS485 serial line for communication with terminals, PC or advanced PLC. For an easier understanding, the supervisor will be called “Master”. If the pump is connected to a PC on which an “HYPERTERMINAL” (or similar) program is running, on the “Master” display appears exactly the response of the pump to the received command. - Page 31 MODBUS RTU In this case, the communication takes place through the standard protocol by Modicon (http://www.modbus.org/).

MAINTENANCE The periodic maintenance is of fundamental importance for the good functioning of the pump and its duration over time. Should be performed in a systematic and precise way, following all the indications given here below. The pump maintenance must be carried out ONLY by qualified technicians and using ONLY original spare parts! Pump Decommissioning Thoroughly clean the pump housing, dosing head and the whole dosing line (see next... - Page 36 Cleaning Service and Replacement of Wearing Parts Attention to dosed chemicals! Before any operation on the pump, discharge the liquid from the pump head and pipes. Take all necessary personal protective measures (i.e. gloves and goggles), as indicated in the SDS of the chemical, which must be always available and updated.
