    Characterization is achieved by entering the head (P610) and corresponding flow (P611), either from empirical measurement or from the manufacturer's specification. The more breakpoints that are defined, the more accurate will be the flow measurement. Breakpoints should be concentrated in areas exhibiting the higher degrees of non linear flow.

  • Page 46: Rake (Screen) Control

    Rake (Screen) Control Screens or rakes are mounted on the inflow channel of the wastewater treatment plant to prevent debris from clogging the equipment. When material builds up on the screen a level differential is created with the water level higher in front of the screen than behind it. When this differential reaches the programmed setpoint the EnviroRanger activates a relay to run mechanical rakes to clean the screen and ensure a steady flow into the treatment process.

  • Page 49: Testing The Configuration

    Testing the Configuration Once you’ve programmed the EnviroRanger you must test the device to ensure that it performs to your specifications. This test can be run in simulation mode or by varying the level in the wet well. The latter is preferred as it more accurately represents running conditions.

  • Page 51: I/O Checkout

    I/O Checkout Once the EnviroRanger is installed a test is usually performed to verify the wiring. Relays Use P119 (IR) Relay Logic Test (page 87) to force a state change and verify that the results are as expected (pump starts, alarm sounds, etc.). Discrete Inputs Use P270 to force the input value and verify that the results are as expected (pump removed from rotation, overflow event, etc.).
  • Page 52: Application Test

    Application Test If the application is being tested by varying the material level (preferred) then ensure that none of the control devices are connected (or at least there is no power available to them). If the application is being tested in simulation mode (and P000 is not -1) then control relays are not energized and they can remain connected.

  • Page 197: Appendix A - Technical Reference

    Appendix A – Technical Reference Transmit Pulse The EnviroRanger transmit pulse consists of one or more electrical “shot” pulses, which are supplied to the Transducer connected to the EnviroRanger terminals. The transducer fires an acoustic “shot” for each electrical pulse supplied. After each shot is fired, sufficient time is provided for echo (shot reflection) reception, before the next (if applicable) shot is fired.

    Unless altered, the sound velocity used for the distance calculation is 344.1 m / s (1129 ft / s).

    When echo processing is complete, (if more than 1 vessel is monitored) the scanning relay changes state to supply the transmit pulse to the other transducer after the Scan Delay (P727). Scan Delay is automatically set by Maximum Process Speed (P003). When high speed scanning is required (sometimes the case for equipment position monitoring), the Scan Delay may be reduced.

  • Page 216: Discrete Inputs

    Discrete Inputs Some pumps can tell the EnviroRanger through contacts that they are running (confirmation) or experiencing a fault. Pumps can be removed from the rotation if they are not pumping efficiently or they are reporting a failure. Failures are reported using the discrete interlocks provided on the EnviroRanger.

  • Page 219 Alternate Duty Backup (P111 = 53) Alternates the lead pump each time the material level cycles and runs only one pump at a time. Relay Operation (for P118 = 2) The setpoints associated with the relays are grouped so that they can be rotated.
  • Page 220 Relay Operation (for P118 = 2) The setpoints associated with the relays are grouped so they can be redistributed based on pump run time ratios. The next pump to start or stop is the one with the required time to actual time ratio. Over time the number of hours demanded of each pump will conform to the ratios specified.
  • Page 221: Other Pump Controls

    Other Pump Controls There are a number of other controls available to modify pump behaviour. Pump Run-on (page 91) Extends the run period for a pump based on the number of pump starts. This allows for the wet well to be pumped lower than usual and reduces sludge build-up on the well bottom.

Use P270 (IDI) Discrete Input Function (page 111) to force the input “on” or “off” and verify that the unit responds as expected. Testing the interlocks is part of a complete system test as described in Testing the Configuration on page 49.
