    The resistor or relay needs to be sized correctly to ensure no damage to the pump transistors. Damage incurred due to incorrect sizing or installation will not be covered by warranty. These solutions require external 24 V power. If connecting to a PLC 24 V is usually available.

  • Page 43: Automatic Control Wiring - Relay Module (Universal And Universal+ Only)

    Automatic control wiring - Relay module (Universal and Universal+ only) The pump can be connected with other devices by means of the screwless terminals connectors within the relay module situated on the side of the pump. The relay module must be removed from the pump housing to allow suitable cables to be connected to the terminal connectors via the watertight cable glands on the module.

  • Page 44: Wiring Up The Terminal Connectors

    Ensure that the relay module cover is correctly secured at all times by all four screws. Failure to do so may compromise the IP66 (NEMA 4X) protection. 14.2 Wiring up the terminal connectors It is the user’s responsibility to ensure the pump’s safe and reliable operation under remote and automatic control.

  • Page 83: Analog 4-20 Ma Mode (Universal And Universal+ Only)

    Analog 4-20 mA mode (Universal and Universal+ only) In this remote operating mode the flowrate will be proportional to the external milliamp signal input received by the pump. The Universal pump will operate at 0 rpm when 4.1 mA is received and maximum rpm when 19.8 mA is received. In the Universal+ pump the relationship between the external milliamp signal and the flow rate is determined by configuring the two points A and B as shown in the graph below.
  • Page 84 To select Analog 4-20 mA mode: Select MODE. Using the +/- keys, scroll to Analog 4-20 mA and press SELECT. The current signal being received by the pump is displayed, for information only, on the HOME screen. Pressing the INFO function key will display further information. m-qdos-allmodels-en-07...
  • Page 85 Press the INFO key again to display the 4-20 mA calibration figures. Analog Scaling Factor The Scaling Factor is a method of adjusting the 4-20 mA profile by using a multiplication factor. Press +/- from the HOME screen to access the scaling factor. Use the +/- keys to enter a multiplication factor.
  • Page 86 Press SELECT once you have chosen the required factor. Press ACCEPT to confirm the new 4-20 mA PROFILE figures. This will not alter the stored A and B points, the multiplication factor will re- scale the 4-20 mA profile. To re- set the original flow rates re-set the multiplication factor to 1.00.
  • Page 87 Flowrate % Figure 22 - 4-20 mA profile Original 4-20 mA profile Scaling factor of 0.5 Scaling factor of 1.5 The 4-20 mA profile is a linear relationship where y=mx+c the scaling factor alters the gradient m. The speed limit function in control settings will also scale the analog signal. The difference between scaling factor and speed limit is that the speed limit is a global variable applied in all modes.

  • Page 93: Contact Mode (All Universal And Universal+ Models)

    Contact Mode (All Universal and Universal+ models) In this operating mode the pump will meter a specific dose of fluid when an external pulse is received. The dose volume is a user defined value between 0.1 ml and 999 l. 23.1 Contact settings To setup contact mode, firstly you will need to define the settings.
  • Page 94 Use NEXT to move the selection bar to the next setting. Use +/- to alter the value of the highlighted setting: The contact dose is the volume of fluid the pump will dispense when an external pulse is received on input pin 2. The flow rate will determine the time taken to complete each dose.

  • Page 96: Fluid Recovery Mode (Manual, Profibus, Universal And Universal+ Only)

    Pulse dosing as an operation mode has its limitations. From an application perspective it is often not the most efficient method of achieving concentration consistency due to the pump only metering when a pulse is received, as opposed to continuously running in proportion to the flow.
  • Page 97 If the pump is already running then the following screen will be displayed. The pump must be stopped before it can be reversed to recover fluid. Press STOP PUMP. An instruction is now displayed. There is a warning to ensure that your system design permits reverse flow.

To achieve this, it is necessary to enable remote fluid recovery functionality.
  • Page 99 This operating method allows for fluid recovery from your delivery line. It should not be used for bulk fluid transfer. Once enabled, remote fluid recovery should be operated in the following sequence: 1. Send a remote stop signal (apply 5 - 24 volts to input pin 1). 2.
