Programming the EnviroRanger To meet the needs of any given application the EnviroRanger must be correctly programmed. The EnviroRanger is programmed by changing parameter values. The available parameters are described in detail in the Parameter Reference on page 55 and sample applications are given in Application Examples on page 23.
Starting Program Mode Entering program mode has the following effects: • all operating data is retained in memory • alarm relay status is held at last known values • control relays are de-energized (unless affected by parameter alteration or is pressed) •...
To access the index of a particular parameter: • Press once • Enter the parameter number • Press twice • Press the number of the required index, or • Press to scroll through the available values Note: When dealing with indexed parameters it is critical to ensure that you set the values accurately.
Dolphin Plus is the primary method of changing EnviroRanger parameters. Most examples in this manual use the icons from the hand programmer but nearly all functions are also available through Dolphin Plus. The Dolphin Plus software is available separately from Milltronics. Changing Parameters (Hand Programmer) From Run mode, press and then to put the unit into Program mode.
Special Parameters View Only Some Parameter Values are for display purposes only and cannot be altered. These are referred to as view only parameters. In the Parameter Reference section of this instruction manual, view only parameters are identified by a “(V)” beside the Parameter Number. Global Some parameter values must be common for all inputs and outputs on the EnviroRanger.
Security All operator programming is retained in non-volatile memory, immune to power interruptions. When programming is complete, the programmer may be locked away to prevent inadvertent programming alteration. As well, the Lock (P000) parameter may be used. Displays The following displays are shown when the EnviroRanger cannot display a number.

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.
Gate Control See Parameters section for complete details on specific parameter values. This technique can also be applied to some types of valves.

Set Relay 1 (Open Gate) Relay 1 is wired to the “open” connections on the gate control. When relay 1 is energized the gate moves up. Parameter Index Value Description P111 Sets relay 1 to energize (open gate) when the level is below 45% of the span P112 (0.63m).
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.

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.

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.).
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.

For normal operation, return to the Run mode. The EnviroRanger will perform reliably, requiring little or no maintenance. Connect (or enable) process control/alarm equipment to the EnviroRanger only after satisfactory performance is verified for all possible operating conditions.

Overflow (61) Use the "Overflow Control" Relay Function to activate a device based upon high levels associated with Overflow conditions. e.g. Open gate (valve) to divert overflow into a holding vessel and optionally turn off pumps. See Overflow / Underflow (P160 to P169) on page 99 for details.
Page 84
P112 (IR) Relay “on” Setpoint The process point at which the relay changes from its “normal” state. For most applications this is the point at which the relay is tripped. For “in- bounds” and “out-of-bounds” alarms it is the high point in the specified range.

To use relay 5 as a general alarm indicator, set P118 to value “3 – negative logic” and wire the alarm for normally open operation. When an alarm event occurs (described below) or when power is cut to the EnviroRanger the circuit closes and the alarm sounds.
Pump Setpoint Modifiers (P121 and P122) These parameters provide alternate ways of starting the pumps in the pump group. See Appendix C – Pump Control on page 215 for descriptions of the pump control algorithms. P121 (G) Pump by Rate Sets the pump relays to accept control by rate of level change once the first “on”...
Page 89
P122 (IR) Pump Service Ratio Selects pump usage based on the run time ratio rather than last used. This parameter only relates to relays with P111=54 or 55. To make this parameter useful, assign it to all of the pump relays. The number assigned to each pump relay represents the ratio that is applied when determining the next pump to start or stop.
Independent Relay Failsafe (P129) P129 (IR) Relay Failsafe Sets the failsafe operation per relay to allow for more flexible programming. Use this feature for relay failsafe operation independent from the Failsafe Material Level (P070). Relay Failsafe is only available for the following relay functions (P111).

Advanced Pump Control Modifiers (P130 to P136) These parameters affect only relays set to pump operation (P111 = 50 to 56). P130 (G) Pump Run-On Interval Sets the number of hours between pump run-on occurrences. One technique of clearing sediment in a “pump-down” wet well is to occasionally run the pump, after the normal “off”...

Page 94
P137 (IR) Pump Group Assigns pumps to groups to allow for multiple pump rotations on one transducer. Use this feature to group pumps (relay points 1 - 5) into group 1 or 2. The feature is applied to pump rotation and occurs independently within each group.
Pump Energy Cost Reduction (P140 to P145) These parameters affect only relays set to pump operation (P111 = 50 to 56). Using these parameters you can configure an EnviroRanger to maximize its operation during periods of low energy cost and minimize its operation during periods of high-energy cost.

P146 (IR) Time of Day Setpoint Use this feature to set the time at which a relay set for time day alarm (P111=9) will trip. Enter the time in HH.MM (24 hour) format. Values 00:00 to 23:59 Page 98 EnviroRanger Programming Reference PL-556...
Overflow / Underflow (P160 to P169) The overflow / underflow parameters allow the EnviroRanger to react to flow conditions caused by storms or other unusual events. When the EnviroRanger enters a flow event the following actions are taken: • Logging starts. See Overflow (CSO) Records (P313 to P316) on page 119 for details.
Page 100
Note: You must specify the correct overflow or underflow settings for your “on” and “off” setpoints. If these values don’t match (for example, Overflow set as 1:1 and “on” setpoint below “off” setpoint) then no action is taken. Use 0:0 to disable overflow logging. If either value is set to “0” then no overflow or underflow action is enabled.

Values 0.000 to 9999 Preset: 0.000 P163 (G) Overflow / Underflow Time Delay Defines the time, in seconds, used to calm (debounce) the flow condition inputs. The time delay is used only when the level source (P160) is a discrete input. Otherwise, the “off”...
Page 102
P165 (IR) Overflow / Underflow Relay Action Determines how relays operate during a flow condition. When a flow condition is detected each relay can be forced on, forced off, or left in its normal state. Use this feature when you want a control device to activate on an overflow or underflow condition.
Flush Systems (P170 to P173) Use this feature to control an electrically operated flush valve on a pump. When a flush valve is run it usually diverts some pump output back into the wet well to stir up sediment. Note: The settings of these parameters affect the operation of all relays with P111 set to “64 –...
Page 104
P172 (G) Flush Interval The number of pump cycles which occur before flush control is enabled. To start a new flush cycle every ten times the pumps are run use the value “10” in this parameter. Values 0 to 9999 Preset: 0 P173 (G) Flush Duration The length of time for each flush cycle that the flush control is active.
Pump Efficiency (P180 to P186) The efficiency of the pumps is calculated on volume change in the wet well or reservoir. Any application using pump efficiency must have accurate values in the Volume (P050 to P055) parameters starting at page 62. Pump faults can also be indicated by input from pump interlocks.
Page 106
P182 (V)(IR) Pump Measured Capacity Displays the value of the actual Pump Capacity as calculated over the Pump Capacity time (P181). This parameter can be used to estimate the Pump Rated Capacity (P183) by running a pump cycle, then viewing this parameter. The units used depend on whether the volume parameters are configured.

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.
Scope Display (P810) Span (P007) + Range Extension (P801) Echo Lock TVT Curve Window Echo Profile Near Blanking Echo Marker (P800) msec x 100 Dolphin Plus Display echo marker echo profile TVT curve Distance Calculation To calculate the transducer to material level (object) distance, the transmission medium (atmosphere) sound velocity (P653) is multiplied by the acoustic transmission to reception time period.
Unless altered, the sound velocity used for the distance calculation is 344.1 m / s (1129 ft / s). Variable air temperature is automatically compensated when a Milltronics ultrasonic / temperature transducer is used. If the transducer is exposed to direct sunlight, use a sunshield or better yet, a separate TS-3 temperature sensor.
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.
Universal, Curved (P050 = 10) This calculation creates a cubic spline approximation of the level/volume curve, providing best results if the curve is non-linear, and there are no sharp angles. Select at least enough breakpoints from the curve to satisfy the following: •...

Enter a Head Breakpoint at each point where the head/flow curve bends sharply (2 minimum). For combination curves (mostly linear but include 1 or more arcs), enter numerous breakpoints along the arc, for best flow calculation accuracy. See also: Checking OCM Flow Characterization on page 50. Universal, Curved (P600 = 5) This calculation creates a cubic spline approximation of the head/flow curve, providing best results if the curve is non-linear, and there are no sharp...
Maximum Process Speed The EnviroRanger’s ability to respond to material level changes is designed to exceed even the most demanding installation requirements. The Maximum Process Speed setting automatically presets various parameters affecting the EnviroRanger response to material level changes as follows: Parameter Values Dependent on Maximum Process Speed (P003)
Appendix B – Troubleshooting Note: Many of the parameters and techniques described here require extensive knowledge of ultrasonic technologies and Milltronics echo processing software. Use this information with caution. If the EnviroRanger setup becomes too confusing use P999 to reset the parameters and start again.

On Milltronics transducers the white wire is negative and the black wire is positive. If the extension wire is colored differently, make sure that it is wired consistently.
Reducing Electrical Noise • Ensure that the transducer cable does not run parallel to other cables carrying high voltage or current. • Move the transducer cable away from noise generators such as variable speed drives. • Put the transducer cable in grounded metal conduit. •...

Standpipe Mountings If the transducer is mounted on or in a standpipe, grind smooth any burrs or welds on the inside or open end, (the end that opens into the vessel). If the problem persists, install a larger diameter or shorter length standpipe, bevel the inside of the bottom end, or cut the open end of the standpipe at a 45 angle.
If the material monitored is a liquid, check for splashing in the vessel. Enter a lower Maximum Process Speed (P003) value to stabilize the Reading, or install a stilling well. (Contact Milltronics or your local distributor). Adjust the Echo Algorithm Use Dolphin Plus to view live sonic profiles and make adjustments to the P820 (G) Algorithm parameter found on page 183.
Should a stable measurement still not be attainable, contact Milltronics or your local distributor. Transducer Ringing If the transducer is mounted too tightly, or if it is mounted so that its side touches something, its resonance characteristics change and this can cause problems.
Appendix C – Pump Control The EnviroRanger has the pump control strategies to solve nearly any water / wastewater application. This section details these strategies for engineers requiring in-depth knowledge of the system and how it operates. Pump Control Options The various methods of pump control are made up of a combination of two control vectors: Pump Duty...
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 217
Fixed Starts pumps based on individual setpoints and always starts the same pumps in the same sequence. Alternate Starts pumps based on the duty schedule and always leads with a new pump. Service Ratio Starts pumps based on user-defined ratio of running time. Fixed Duty Assist (P111 = 50) Ties the indexed pump relay directly to the indexed setpoint.
Page 218
Relay Table The following table shows relay status when each setpoint is reached. Relays index on 3 on 2 on 1 off 0 Alternate Duty Assist (P111 = 52) Alternates the lead pump each time the material level cycles and runs all pumps together.
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.
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.
Appendix D – Discrete inputs The discrete inputs on the EnviroRanger allow the unit to be more flexible by interlocking control functions with external conditions in the wet well. To configure a discrete input on the EnviroRanger, follow these steps. Wire the Discrete Input The discrete input contacts are either normally-open or normally-closed when the system state is normal.
Program the Interlock Logic The interlock can take one of three forms, detailed below. Overflow or Underflow Event Used to detect an unusual flow event such as a storm overflowing a wet well. Determine the Source Set P160 (G) Overflow / Underflow Level Source as described on page 99. Determine the Action Set P165 (IR) Overflow / Underflow Relay Action as described on page 102.
Page 225
Pump Status Used to confirm that a pump is operating correctly and to remove it from the duty schedule if it is not. The interlock events that can remove a pump from the duty schedule are Failure to Start Use P503 (IR) Pump Run Status Allocation and P504 (IR) Pump Run Status Time Delay as detailed on page 131.
Test the Interlock Once wired and programmed test the interlocks to verify operation. 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.
