    Refitting the relay module cover Ensure the sealing strip is undamaged and positioned within its channel on the side of the drive housing. Hold the module cover in place, taking care not to disturb the sealing strip. Starting with the top left screw, tighten the four retaining screws to 2.5Nm.
  • Page 32 For convenience of wiring more than 8 conductors per cable may be awkward to handle. 1. Use a suitable 21mm spanner to unscrew the sealing plugs. 2. Screw in the supplied ½” NPT cable glands complete with new sealing washers in place of the plug, ensuring that the retaining nut is properly seated.

For example if the qdos20 4-20mA profile is 0% flow at 4mA to 100% flow at 20mA and a speed limit of 33 rpm is applied, followed by a scaling factor of 0.5, then the output will be 30%. If a scaling factor of 2 is applied in the same scenario then the output will be 33 rpm or 60%, as the speed limit takes precedence over the scaling factor.

    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 81 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.
