Introduction
The EnviroRanger is intended for advanced water and wastewater applications. This device can handle virtually all of your pump control and level monitoring needs – often replacing expensive PLCs and integrating into a SCADA system for a fraction of the cost of competitive systems.
The EnviroRanger is programmable.
It can be configured for nearly any water or wastewater application and control up to five pumps, gates, or alarms – and can communicate its status by way of direct serial connection, modem, or industrial communication network.
The EnviroRanger is flexible.
It can take discrete input from pumps or other devices and modify its operation based on that input. It can also time events to maximize efficiency or minimize cost.

About the EnviroRanger
The EnviroRanger has two modes of operation:
Program Mode
Program mode allows the programmer to change parameter values and alter the way the unit operates.
Note:
If the unit has been programmed and is in normal operation then putting it in program mode will de-energize all control relay outputs. Therefore it is advisable to bypass the EnviroRanger while programming the unit to avoid overflows.
After a programming alteration, do not use the EnviroRanger to operate alarms or controls until system programming and performance is verified.
To enter Program mode from Run mode:
About the EnviroRanger
1. Press the program button on the front of the device (Rack or Panel only)
2. Look for the program icon on the display (
3. Press
If the EnviroRanger is idle in Program mode for more than 5 minutes, then Run mode is automatically entered.
For information on the individual programming parameters see the chapters Application Examples on page 23 or Parameter Reference on page 55.
and then .
) (Rack or Panel only)
Run Mode
Run mode detects material level and provides control functions. The EnviroRanger automatically starts up in the Run mode when power is applied.
To enter Run mode from Program mode, press
“----“ is displayed briefly while the measurement reading is calculated and verified. Reading level and other data is displayed and any relays are operated based on the unit’s programming.
.
While the unit is in Run mode you can view system status. This information is shown on the LCD on the front of the unit or can be accessed remotely using communications software.

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.
Rack or Panel Mount
To enter program mode on a rack or panel mount unit:
Press the program button on the front of the unit (shown at right)
This icon ( canbeplacedinprogrammode.
) appears when the unit
Wall Mount
The wall mount version has no program button, it is always ready for program mode.
Aim the hand programmer and press the program keys on the hand programmer (shown above).
Programming
The program button allows multiple units to be installed close together and still be programmed one at a time.
Program mode is confirmed by the icon ( disable programming, press again. Run mode is confirmed by absence of the icon in the display. Disable all nearby units to avoid inadvertent programming when using the infrared handheld programmer.
Note:
Unless otherwise noted, each valid key press should produce a change in the LCD, look for this when programming the unit.
PL-556 EnviroRanger Programming Reference Page 15
) appearing in the display. To
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)
discrete inputs are detected but not acted on
The Run mode is automatically re-entered if the EnviroRanger is left unattended in the program mode for an extended period (approximately 5 minutes).
Parameter Indexing
Parameters are indexed if they can apply to more than one input or output. The index value defines to which input or output the particular parameter value relates. Indexed parameters contain a value for each index, even if that index is not used.
Note:
To set all indexed values for a given parameter to the same value use index “0”.
Programming
For example, to change the Relay Control Function (P111) for relay three you must ensure that “03” is displayed in the index field before you change the parameter value.
In this manual parameter index values are shown in brackets after the parameter number. For example P111[3] refers to parameter 111 index value 3.
Note:
Transducer parameters are indexed only if Operation (P001) is set to “Difference” (value=4) or “Average” (value=5). An indexed transducer is commonly referred to as a Point (short for measurement point). The term Point Number refers to indexed transducers.

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)
1. From Run mode, press and then to put the unit into Program mode.
Note:
If Parameter Value alteration is not permitted, access the Lock parameter (P000) and enter the security code, (see Programming Security).
2. Press to select the Parameter Number field (see page 10)
3. Type the Parameter Number (e.g. 110) When you type the third digit the value for that parameter is shown
For lower numbered parameters, such as 007, you can type the number “7” and then press
4. Type the new value
5. Press
Programming
The EnviroRanger interprets the value and either accepts it, or replaces it with a valid value. See the Parameter Reference for descriptions of values.
The “?” icon indicates that the EnviroRanger has accepted the value but that it conflicts with other values entered. Double-check your programming.
By default the scroll keys ( and any that have been changed. Use P733 (G) Scroll Access on page 167
to allow all parameters to be scroll-accessed.

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. These are referred to as global parameters.
When a global parameter is accessed, the index display automatically disappears. When a non-global parameter is accessed, the index previously selected for that parameter is displayed.
In the Parameter Reference section of this manual, Global parameters are identified by a “(G)” beside the Parameter Number.
Indexed
Some parameter values relate to indexed items. Examples of this are parameters which are different for each:
Relay, shown with an “(IR)”
Transducer, shown with an “(IT)”
Discrete Input, shown with an “(IDI)”
For full descriptions of parameters and how they are indexed, see How to Read the Reference on page 55.
Parameter Reset
To set any parameter back to the factory default:
Display the appropriate parameter number
Display the appropriate index value (if required)
Press
Press
Programming
To reset all parameters to preset values, see Master Reset (P999).
Perform a Master Reset (P999) to reset all parameters to “original” values before initial system installation, following a software upgrade, or whenever complete reprogramming is required. Use Dolphin Plus to store and retrieve parameter groups.
PL-556 EnviroRanger Programming Reference Page 19
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.

Planning Considerations
Review the Application
When reviewing the application into which the EnviroRanger will be installed, note the:
Pump control system inputs and outputs
Dimensions of the wet well or reservoir (especially if pumped volume will be
used)
Maximum measurement distance required (will determine transducer requirement)
Communication type required (modem, industrial communication network)
Design the Control Scheme
Choose the most appropriate pump control strategy from those available. See Appendix C – Pump Control on page 215 for a description of the EnviroRanger pump control strategies and options.
Map the Control Scheme to EnviroRanger
Once the control scheme is designed, map its requirements to the EnviroRanger’s parameters. Be aware of the EnviroRanger’s abilities:
Number of relay outputs (5)
Number of discrete inputs (8)
Number of mA inputs (1)
Install the EnviroRanger
Mount and wire the EnviroRanger as detailed in the EnviroRanger Installation Guide (PL-557).
Program the EnviroRanger
Use the Application Examples (page 23) and Parameter Reference (page
55) to determine the best method of programming the EnviroRanger to satisfy the control scheme.
Planning
Use either Dolphin Plus or a hand programmer to set the parameter values to those required.
PL-556 EnviroRanger Programming Reference Page 21
Test the Installation
Test the inputs and outputs as shown in Testing the Configuration on page
49.
Document the Installation
Use Dolphin Plus to record your parameter values for later reference.
Planning
Page 22 EnviroRanger Programming Reference PL-556
Application Examples
Note:
When the unit is first turned on it will give distance (P001=3) in meters from the transducer face to the material surface. If the wet well or reservoir is empty then this reading is the empty distance (P006) from the transducer face to the reservoir bottom. P006 is preset to 5.0m (16.4’), so reservoirs deeper than that will read LOE until P006 is updated.
Output Limitations
The standard EnviroRanger comes with 5 relay outputs. Each relay is programmed using P111 (IR) Relay Control Function (see page 74) from a large number of options. Use these application examples as a guideline for the relay programming.

Open Channel Monitoring (OCM)
See Parameters section for complete details on specific parameter values.
There are three ways of defining an OCM installation depending on your Primary Measuring Device (PMD). See the listed examples for required parameters.
Dimensional
is provided for some common weir and flume typ es. For these PMDs the dimensions (P602) are entered directly.
Exponential
is provided for most other weir and flume types. For these PMDs the exponent provided by the manufacturer is entered. Flow is calculated using the exponent (P601) and the maximum values (P603 and P604).
Universal
is provided to accommodate any installation not covered by the first two types. For all other PMDs the head-to-flow curve can be plotted and approximated based on known breakpoints, usually supplied by the PMD manufacturer.

Universal Calculation Support
When the primary measuring device (PMD) doesn’t fit one of the standard types it can be programmed using a universal characterization. When Universal is selected as the PMD type (P600) then both P610 and P611 must be entered to define the flow.
Two curve types are supported:
P600 = 4 – linear (piecewise linear)
P600 = 5 – curved (cubic spline)
Both are shown in the following chart:
Typical Flow Characterization
Maximums (P603, P604)
linear
Flow (P611)
Application Examples
Page 42 EnviroRanger Programming Reference PL-556
curved
Head (P610)
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. A maximum of 32 breakpoints can be defined. The curve’s end point is always specified by the parameters Maximum Head (P603) and Maximum Flow (P604) for a maximum total of 33 breakpoints.
Use as many breakpoints as required by the complexity of your PMD.
See Flow Calculation on page 201 for more information.

Sets relay 2 to energize (close gate) when the level is above 55% of the span (0.77m). The timing (P114, P115) of relay 2 is set from the relay 1 setpoints.
Note:
Care must be taken to adjust P114 and P115 for proper proportional integral (PI) control without overshoot or cycling. P114 is equivalent to proportional band (P). P115 is equivalent to reset (I).
The transducer can also be placed upstream from the gate to control upstream head.

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.

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. However, if it is not possible to do a physical test, the simulation mode will ensure that all control programming is correct.
Simulation
When in simulation mode the LCD shows the EnviroRanger’s reaction to level changes but any pump or control relays are held off. Alarm relays are allowed to operate based on the simulation.
To allow pump or control relays to operate based on the simulated level, set P000 to –1.

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.).
1. Go to P270[n] where n = the discrete input to be tested
2. Set to 0 to force the input off
3. Go to P275[n] to verify that the value is forced
4. Check the state of outputs to ensure that they respond as expected
5. Go to P270[n]
6. Set to 1 to force the input on
7. Go to P275[n] to verify that the value is forced

Use P254 to test the mA input value against a true level. Use a trusted external mA source to generate the signal required for testing and verify the incoming signal with P260. As the mA level is changed ensure that the system responds as expected.
Reset for Run Mode
Once testing is complete and the unit is ready for operation it is good practice to clear any pump interlocks. Do this by setting P510[0] to 0.

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).

2. If alternate Reading units, failsafe action, or relay operation is desired,
3. If the system performance experiences problems, see Appendix B –
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.
While the level is being cycled, check the results of the discrete inputs by either closing the circuit externally (preferred) or using P270 (IDI) Discrete Input Function on page 111 to force the input on or off. Try all possible combinations to thoroughly test the setup. For each combination run a complete cycle to verify that the pumps operate as expected.
Monitor system performance carefully, under all anticipated operating conditions.

Troubleshooting on page 205.
If all operating conditions cannot be observed during the System Performance Evaluation, refer to Measurement (P920 to P927) on page 193 for simulation instructions. Perform a Reading Measurement simulation to verify programming.
Usually, when a simulation is run, alarm relays will energize based on programming but control relays will not.

P000 (G) Lock
Use this parameter to secure the EnviroRanger from changes.
WARNING Use this lock as backup security only. It uses a fixed value which can be discovered by unauthorized personnel.
Access this parameter directly (type the number 000) and enter any value (other than 1954) to secure the programming lock. To unlock the EnviroRanger, access this parameter and enter the value “1954”.
When lock is activated, the EnviroRanger may be switched from the RUN mode to the program mode and the value of any parameter may be viewed but not altered.
Normally, during a measurement simulation (see Measurement Parameters,
Parameter Reference
P920 - P926), pump or control relays remain de-energized. If desired, set Lock for “simulation controls” to have pump or control relays function based on the simulated level.
Simulation mode reverts to 1954 after the unit is idle for 10 minutes.
Simulate using P920 usually does not energize control relays. If this parameter is set to –1 then all relays will energize when the P920 simulation is run.

If “DPD” or “DPA” is entered, either 2 transducers of the same type are required, or one transducer and one mA input. If two transducers are used all transducer parameters become indexed, and a third level point is calculated:
DPD (difference) = Point 1 - Point 2
DPA (average) = (Point 1 + Point 2) / 2
For these operations any of three level points (transducer 1, transducer 2, or the calculated point) can be used to trigger relays (see P110 (IR) Level Source on page 74).

Failsafe (P070 to P072)
The failsafe parameters are used to ensure that if no valid level reading is available then the devices controlled by the EnviroRanger default to an appropriate state.
By default, if an error condition is detected then the display and relay status are held at their last "known" values and the Failsafe Timer (see below) is activated. If the Failsafe Timer expires and the unit is still in an error condition then P071 (IT) Failsafe Material Level determines the level reading.
Control the reaction of the EnviroRanger to extended error conditions by configuring parameter P071 (IT) Failsafe Material Level, described on page 70, and ensure that the fail state is optimal for your application.
If Failsafe Operation activates frequently, seeAppendix B – Troubleshooting on page 205.
P070 (G) Failsafe Timer
Parameter Reference
The time elapsed, in minutes, of invalid measurements before Failsafe State is activated.
Once activated, the Failsafe state initiates the following:
1. P071 (IT) Failsafe Material Level (described on page 70) is activated as the material level reading.
a. The unit responds to the new level as programmed (control and alarm
relays activate as defined by the programming)
b. Individual relays can have independent failsafe responses. See P129
(IR) Relay Failsafe on page 90.
2. The appropriate error is displayed:
a. LOE for loss of echo from the transducer b. Short for a shorted transducer cable c. Open for a cut transducer cable d. Error for all other problems
When modifying the preset value, use one that is short enough to protect the process but long enough to avoid false alarms. Use 0 (no delay) only for testing purposes.
This value is automatically altered when P003 (IT) Maximum Process Speed (page 58) is altered.

to display the Auxiliary Function symbol, or as required to scroll to the desired option, to enter the value.
Keep the last known material level Use the full Span (P007) as the material level Use Empty (P006) as the material level Use an arbitrary value (between 0 and 150% of span)
Alarm relays have P129 = “OFF” and so react to the Failsafe Material Level.

Relays (P100 to P119)
The EnviroRanger comes with five relays, sometimes called digital outputs, typically used to control devices and alarms. While the number of devices directly controlled is limited by the relays all control functions are accessible through software. Refer to the EnviroRanger Communications Reference for information on accessing information through software.
Each parameter is indexed to the five relays. See Special Parameters on page 19 for more information.
Preset Applications (P100)
The EnviroRanger makes standard applications easier to program by providing an extensive list of presets.
Control Functions (P111)
Each relay can be configured independently to take advantage of the flexibility built into the EnviroRanger. Configure the relays independently to
Parameter Reference
take advantage of the advanced features of the EnviroRanger. Start with a preset application and then change only the required parameters to make the task more efficient.
Setpoints (P112, P113, P114, P115)
Each relay is triggered by one or more setpoints. The setpoints can be based on absolute level (P112, P113), rate of change (P702, P703), or time (P114, P115). Each different control function specifies which setpoints are required.
P100 (G) Preset Applications
There are six preset applications which can help configure the EnviroRanger for typical use or for bench testing before commissioning.
If your application is similar to those listed here then select the appropriate one and then change only the parameters required. If none of these preset applications suits your needs then move on to P111 (IR) Relay Control Function on page 74.
Note:
Programming the relays independently is the most common method used.
For screen applications (P100=5) the EnviroRanger’s operation must be set to difference (P001=4).

The relay is activated by units of totalized flow from Pumped Volume or OCM:
Pumped Volume (P001=7)
Calculates volume based on wet well draw down and pump run times. See Pumped Volume Totalizer (P622 to P623) on page 148 for details.
Multiple Contacts
Pumped volume is calculated at the end of the pump cycle. Totalized volume given through a relay set up for “totalizer (40)” will be given in bursts at this time. Both the open and closed times for the relay contact are provided by P645 and are preset to 0.2 seconds. Partial units are added to the next pump cycle.

AWordonPumpRotation
When more than one pump is started the previously running pump is switched off. Only one pump at a time is ever running.
Fixed (50, 51)
The “on” and “off” setpoints remain static (as programmed) for each pump relay.
Alternate (52, 53)
The “on” and “off” setpoints are shared for the pump group and are rotated each time the material level cycles.
Service (54, 55)
The “on” and “off” setpoints are shared for the pump group and pumps are started in order of run time based on a user-defined ratio. Ratios are specified using P122 (IR) Pump Service Ratio on page 89.
The EnviroRanger groups pumps together based on the Relay Function and the indexed transducer.
If there are four pumps indexed to a single transducer with two pumps assigned value 52 and two pumps assigned value 54 then the EnviroRanger groups both “52’s” and both “54’s” and performs the rotation on each group separately.
If all four pumps were assigned value “52” then all four would be grouped and rotation would happen on all four. The only way to circumvent this grouping is to use P137 (IR) Pump Group on page 52).
Parameter Reference
PL-556 EnviroRanger Programming Reference Page 81
FIFO (56)
The “on” and “off” setpoints are shared for the pump group and pumps are started using the alternate algorithm but are shut off using the “first in, first out” rule.
“Off” setpoints are generally staggered.
Note:
Do not use “FIFO” pump sequencing with volume totalization because for totalization to work all of the pump “off” setpoints must be the same.

The relay contact operation is “normally closed” for alarms and “normally open” for controls. See P111 (IR) Relay Control Function for more information.
Power Failure
When power is cut to the EnviroRanger its relays fail in the following states:
Rack or Panel Mount Wall Mount
Relay Fail State Relay Fail State
1-4 Open 1-4 Open
5 Closed 5 Open or Closed
6
Relay 5 is a Form C type on the Wall mount EnviroRanger so you can wire it either normally open or normally closed. Check the wiring before programming.
6
Page 86 EnviroRanger Programming Reference PL-556
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.
Positive Logic
In software all relays are programmed the same way, with “on” setpoints indicating when to change the relay contact state (open or closed). This parameter allows the reversal of the operation so that relay contacts can be “normally closed” or “normally open.” P118 is preset to “2” which is positive logic.
Negative Logic
When P118 = 3 (negative logic) the operation for the indexed relay is reversed from normal.

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” setpoint is reached.
Use this function when there are multiple pumps which should be controlled by rate of level change rather than setpoints. Pumping costs can be less because only the highest “on” setpoint needs to be programmed and this resultsinalowerdifferenceinheadtothenextwetwellwhich,inturn, results in less energy being used to pump out the well.
Parameter Reference
When the first “on” setpoint is reached the pumps will start, one by one, until the material level is changing at a rate the same or greater than the one specified in:
P703 (G) Emptying Indicator on page 160 (pump down application)
P702 (G) Filling Indicator on page 160 (pump up application)
The delay between pump starts is set by P132 (G) Pump Start Delay on page 92.
This parameter only applies to any relays set to pump control (P111 = 50 to
56).
Notes:
All pump control relay “on” and “off” setpoints must be set to the same value.
If the level is within 5% of Span (P007) of the “off” setpoint then the next pump is not started.
Values
0 * off (pump by level) 1 on (pump by rate)

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.
Example
Pump Assigned Relay Service Ratio
112 221
This service ratio would run pump one twice as often as pump two.
Notes:
The EnviroRanger will not sacrifice other pumping strategies to ensure that the ratio is held true.
If the pump relays are set to the same value then the ratio equals 1:1 and all pumps are used equally (preset).
Parameter Reference
Use this feature to predetermine pump usage if a "Pump Service Ratio" Relay Function (P111 = 54 or 55) is selected.
When more than one pump is assigned a Pump Service Ratio value (in any time units) and a pump start is required (Relay Setpoint “on”, P112), the pump with the least running hours (with respect to the assigned ratio values) is started.
Conversely, when a pump stop is required (Relay Setpoint “off” (P113), the pump with the most running hours (as compared to the assigned ratio values), stops.

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” setpoint is reached, to force some of the solid material through. This parameter indicates how many hours should elapse between pump run-on occurrences.
Only the last pump running is allowed to run-on.

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. The methods used to achieve this are:
1. Emptying the wet well just prior to the high cost period, regardless of material level (P141, P142, and P143)
2. Changing setpoints for high cost and low cost periods (P144 and P145)

Energy Savings Example
The following example illustrates high energy cost usage reduction and/or elimination by utilizing the EnviroRanger Pump Energy Cost Reduction features on a wet well (pump down application).
Parameter Reference
Normal Operation
Uses the standard “on” and “off” setpoints (P112 / P113). Energy cost is at minimum.
Peak Lead time (P143 = 60 minutes)
Pumps down the wet well regardless of the Relay “on” Setpoints. This ensures that the wet well starts the high cost period at the pumps’ “off” setpoint. Energy cost is at minimum.
Peak Start Time (P141 = 17:30)
Starts using the energy savings setpoints (P144 and P145). Energy cost is at maximum.
Peak End Time (P142 = 21:30)
Returns to normal setpoints (P112 and P113). Energy cost returns to minimum.
Note:
When the Peak “on” Setpoint is not reached, no energy is used during the "high cost" period. If the Peak “on” Setpoint is reached, the Wet Well is only pumped down to 60%, thereby minimizing "high cost" energy usage.

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.
Relays are overridden.
See P165 (IR) Overflow / Underflow Relay Action on page 102 for details.
Control relays are tripped.
See P111 (IR) Control (values 60-65) on page 82 for details of option “61.”
Communications are updated.
See the EnviroRanger Communications Reference for details.
P169 is updated.
See P169 (V) Flow Condition on page 102 for details.
When the EnviroRanger ends a flow event the logging is stopped and all other actions are ended.
P160 (G) Overflow / Underflow Level Source
Defines the source used to detect a flow condition.
The input for the flow condition is specified as x:y where:
Parameter Reference
Input Type xvalue yvalue
Overflow :
Underflow:
For example, to configure a float to trigger an overflow event you would connect it to one of the discrete inputs, in this example 5, and the value for P160 would be 2:5.

Transducer 1
Discrete Input 2 1 to 8 – references the DI used
Transducer 3
Discrete Input 4 1 to 8 – references the DI used
1 – transducer 1 2 – transducer 2 3 – average or difference (P001=4 or 5)
1 – transducer 1 2 – transducer 2 3 – average or difference (P001=4 or 5)
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.
To enter a colon “:”, press the decimal “.” button on the keypad.
Values
x:y Preset: 0:0
P161 (G) Overflow / Underflow Setpoint “on””
The point at which the flow event is triggered.
Parameter Reference
This setpoint is used only if the level source (P160) is a transducer or mA input. If a discrete input is used to detect overflow or underflow then this parameter is ignored.
Notes:
For overflow events the “on” setpoint must be above the “off” setpoint or no events are logged.
For underflow events the “off” setpoint must be above the “on” setpoint or no events are logged.
Values
0.000 to 9999 Preset: 0.000
P162 (G) Overflow / Underflow Setpoint “off”
The point at which the flow event is reset.
This setpoint is used only if the level source (P160) is a transducer or mA input. If a discrete input is used to detect overflow or underflow then this parameter is ignored.
Notes:
For overflow events the “on” setpoint must be above the “off” setpoint or no events are logged.
For underflow events the “off” setpoint must be above the “on” setpoint or no events are logged.
