  • Page 15: Good Pump Installation Practice

    Good pump installation practice General recommendations It is recommended that the pump is sited on a flat, horizontal, rigid surface, free from excessive vibration, to ensure the correct lubrication of the gearbox and correct pumphead operation. Allow a free flow of air around the pump to ensure that heat can be dissipated. Ensure that the ambient temperature around the pump does not exceed the recommended maximum operating temperature.

  • Page 16: Dos And Don'ts

    If in any doubt about the compatibility of a tube material and the duty fluid, request a Watson-Marlow tube sample card for immersion trials. When using Marprene or Bioprene continuous tubing, do re-tension the tube after the first 30 minutes of running.

    Connecting to a power supply A well regulated electrical mains supply is required along with cable connections conforming to the best practice of noise immunity. It is not recommended to site these drives alongside electrical devices that may generate mains-borne noise, for example 3-phase contactors and inductive heaters. Set the voltage selector to 115V for 100-120V 50/60Hz supplies or 230V for 200- 240V 50/60Hz supplies.

  • Page 59: Analog Mode

    Analog mode In this remote operating mode the flow rate will be proportional to the external milliamp or voltage signal input received by the pump. The relationship between the external analog signal and the flow rate is determined by configuring the two points A and B as shown in the graph below. The rate of flow can be proportional or inversely proportional to the analog input.

  • Page 60: Analog Calibration

    19.1 Analog calibration The pump must be stopped before attempting to calibrate the values. High and low signals must be within range. If the signal sent is out of range you will not be able to set the signal input value and progress to the next step in the process. Select MENU, then select MODE menu.
