Notes For Level Probe Backup Functions:
For status of Level Probe inputs see Coils 583 - 592 in SCADA Register 40037.
1. When the controller is set up to follow a 10 Electrode Conductance Level Probe as the primary level input source (Parameter F.19
= 2 or 3), the backup functions described here are not needed and will not operate.
2. If a Function (such as Pump Control – 3RD On Level) is not desired set the respective parameter equal to zero.
3. An effective Backup Pump Control would involve having a 3 point Level Probe placed high in the wet well. The Level Probe would
be connected to Connector J25 terminals 1, 2, and 3. The Off Level should be made to operate from the bottom Electrode by
setting Parameter b.02 = 3. The 1ST On Level should be set to operate from Electrode 2 by setting Parameter b.03 = 2. The
2ND On Level should be set to operate from Electrode 1 by setting Parameter b.04 = 1. If pump three is present set the 3RD On
Level to operated from Electrode 1 by setting Parameter b.05 = 1.
4. If a Backup High Level Alarm is desired, set Parameter b.06 to the number of the Electrode Input that the High Level Probe is connected to. This feature is for alarm and telemetry only and will not function as a redundant pump call. See SCADA notes page 31.
5. If a Backup Low Level Alarm is desired, set Parameter b.01 to the number of the Electrode Input that the Low Level Probe is connected to. This feature is for alarm and telemetry only and will not function as a redundant pump off. See SCADA notes page 31.
6. Whenever the Backup Pump Control is active the Fault indicator will be on and Fault Code of 30 will be present in Parameter FLC,
and set Coil 15 in SCADA Register 40001.

Pump Stop Mode - Parameter P.17
This Parameter establishes which pump is the next one to be stopped, when there are two or more pumps on.
The Controller has a corresponding “Pump Off Level” setting for each of the “Pump On Level” settings. For the
“Pump Stop Mode” feature to operate, the “Pump Off Level” settings must be set on different levels. If all the
“Pump Off Level” settings are set on the same level it does not matter what Parameter P.17 is set on.
First On Last Off - In this mode, as the level reaches one of the “Pump Off Level” settings, the pump that was
most recently turned on is turned off, leaving the one that was call to run first still running.
First On First Off - In this mode, as the level reaches one of the “Pump Off Level” settings, the pump that was
most recently turned on is left on and the pump that has been on the longest is turned off. This results in a longer
cool down period for each pump between starts. This mode works the best in stations where one pump is required
to run for a long period of time, with an occasional need for an additional pump.

Automatic Alternation - Parameter P.18
This Parameter is provided so that normal automatic alternation may be disabled (turned off). Typically, normal
alternation is disabled only in applications that have an external Time Clock used to alternated the pumps.
(The Time Clock would be connected to a Discrete Input programmed for “External Alternation” , Function 5.)

Forced Lead Pump Position - Parameter P.39
This Parameter is provided so that a fixed sequence may be established with the selected pump always as lead.
For example setting Parameter P.39 on 1 will cause a fixed pump call sequence of 1-2-3. Parameter P.39 may
also be changed by writing a 0,1,2, or 3 to SCADA Register 40022.

This feature may be used to ensure that alternation periodically occurs even in applications that tend to run one
pump for a long period of time. The internal Time Clock starts and runs whenever at least one pump is called to
run. When it times out, it forces the alternation of the pumps and then resets the Time Clock. The Time Clock is
also reset each time a Normal Alternation Occurs.

Parameter P.16 = 3
Notes:
1. This sequence is used when it is required that pump 1 always be lead, and
when it must be turned off when another pump(s) comes on. When a pump
from the second group is required, pump 1 is first turned off, then after the

sequence.
7. The External Alternation feature will not function when using this sequence.
8. If connected to a SCADA system, the lead pump position may be set by
writing to Register 40022 (Same as Parameter P.39).
9. Time Based Alternation using Parameter P.51 will not function when using
this sequence.
STEPPED ON/OFF SEQUENCE
Only One Pump Runs at a Time
Parameter P.16 = 6
Notes:
1. This sequence is used in stations where there is a significant difference in
the size of the pumps, and when only one pump is to be allowed to run at a
time. When there is a need for more pumping, the smaller pump is turned
off and the next larger pump is called to run. As the need for pumping decreases, the larger pump is turned off and a smaller pump is called to run in
its place (provided the Off Levels are staggered).
2. The Lag Pump Delay operates to give the check valve of the pump being
turned off time to close before another pump is called to run.
3. Discrete Inputs programmed as Pump 1-3 Disable inputs should be used to
disable pumps that are not able to run. It is critical that the largest pump in
the group, have some type of pump fault logic connected to the respective
Pump Disable discrete input.
4. Discrete Inputs programmed as Sequence Inputs 1-3 will not function when
using this sequence.
5. Parameter P.39 has no effect on this sequence.
6. The Pump Stop Mode (Parameter P.17) has no effect on this sequence.
7. Automatic Alternation Enable/Disable (Parameter P.18) has no effect on this

DISCRETE INPUT FUNCTIONS
The following is a description of the Functions that may be assigned to the Discrete Inputs using Parameters F.01 - F.12:
Notes: 1. All Discrete Inputs are originally programmed with default Functions, but they may be changed at any time using
Parameters F.01 - F.12.
2. Each of the Functions may only be assigned to one Discrete Input. If assigned to more than one input, the Fault
indicator will come on and Fault Code 8 will be generated.
Pump 1 (2, 3) Disable - Functions 1 - 3
With Parameter P.52 = 0 (Normal Mode)
When a Discrete Input programmed as a “Pump 1 (2, 3) Disable” is closed, the respective pump will be
disabled (not allowed to run) and skipped over in the pump call sequence.
With Parameter P.52 = 1 (Logic Inverted Mode)
When a Discrete Input programmed as a “Pump 1 (2, 3) Disable” is open, the respective pump will be disabled (not allowed to run) and skipped over in the pump call sequence.
Whenever a pump is disabled the next available pump is called in its place when needed. The one exception to
this, is the Alternation Sequence - Pump 1 Always Lead (Parameter P.16 = 3), where disabling pump 1 will not
result in another pump taking it’s place.
Level Freeze - Function 4
When a Discrete Input programmed for “Level Freeze” is first closed, the Wet Well Level is held steady or frozen
so that a bubbler system’s bubbler tube may be purge without causing the Level to jump up or down. The external
logic that performs the bubbler tube purge must provide the Discrete Input closure prior to a significant change in
the 4-20mA analog Level input. The Level Freeze logic keeps the Level frozen for 10 seconds and then releases
it, regardless of whether the Discrete Input had re-opened or not. It does not matter how long the input remains
closed, but it must be opened to reset the logic.
External Alternation - Function 5
Each time the Discrete Input programmed for “External Alternation“ transitions from open to closed, alternation of
the pumps will occur. It does not matter how long the input remains closed, but it must be opened to reset the
logic. If no pumps were running when the Discrete Input is closed, the alternation of the designated lead pump will
still occur. Typically this input is connected to contacts from an external Time Clock.
On Generator - Function 6
In cases where the Emergency Generator is not sized large enough to run all the available pumps, closing a Discrete Input programmed for “On Generator” will limit the number of pumps called to run to the number preset using Parameter P.15. Typically a contacts from the Transfer Switch are connected to this input.
All Pump Disable - Function 7
When a Discrete Input programmed for “All Pump Disable” is closed, all the pumps are disabled (not allowed to
run), the Fault indicator will come on, the Power indicator will flash, and Fault Code 18 will be generated. This
Function also disables pump operation from Float Backup using Functions 24 - 29, or Level Probe Backup using
Parameters b.01 - b.06. The Discrete Input is typically connect to Phase Monitor contacts.
When the Discrete Input opens, the Lag Pump Delay must expire before the first pump is allowed to run. If any
additional pumps are required, the Lag Pump Delay must expire between each one called to run.
Sequence Input 1 (2, 3) - Functions 8 - 10
When a Discrete Input programmed as a “Sequence Input 1 (2, 3)” is closed, it disables normal alternation and
forces one of the pumps to always be lead pump. For example, closing “Sequence Input 1” forces pump 1 to be
lead and sets the sequence of 1 - 2 - 3 (assuming Parameter P.16 = 1). See page 35 for connection diagrams.
14
DISCRETE INPUT FUNCTIONS
Low Level Alarm - Function 11
When a Discrete Input programmed for “Low Level Alarm“ is closed, the Low Level indicator will come on and the
Low Level Alarm relay contacts will close. This Function is for alarm and indication only and will not disable pump
operation. Also see Function 24.
High Level Alarm - Function 12
When a Discrete Input programmed for “High Level Alarm“ is closed, the High Level indicator will come on and
the High Level Alarm relay contacts will close. This Function is for alarm and indication only and will not affect
pump operation. Also see Function 29.
Telemetry E - D - Functions 13 - 22
When the Discrete Input(s) programmed for “Telemetry E-D” are closed, no control Function in the Controller is
performed, only the status of the Discrete Inputs is placed in predetermined Coils in SCADA Registers 40001 and
40008. These Functions are use to assign any of the available Discrete Inputs to a specific Coil. See Page 27.
Normal Pump Operation Disable - Function 23
When a Discrete Input programmed for “Normal Pump Operation Disable” is closed, all the pumps are disabled
(not allowed to run), the Fault indicator will come on, and Fault Code 15 will be generated. However, this Function
does allow pump operation from Float Backup using Functions 24 - 29, or Level Probe Backup using Parameters
b.01 - b.06.
This Function is used when it is required that a backup system have complete control of the pumps. The Discrete
Input must be connected to contacts that closes when external logic determines that switching control of the
pumps to the backup system is necessary.
Float Backup - Low Level - Function 24
When a Discrete Input programmed for “Float Backup - Low Level“ is closed, the Low Level indicator will come on
and the Low Level Alarm relay contacts will close. Also see Function 11.
Pump Down Mode (Parameter P.19 = 1)
All pump operation will be disabled when the “Float Backup - Low Level“ input closes.
When the “Float Backup - Low Level“ input opens the “Pump Re-enable Delay” (set using Parameter P.37),
must expire before pump operation is allowed.
Pump Up Mode (Parameter P.19 = 2)
All available pumps will be called to run when the “Float Backup - Low Level“ input closes, assuming that the
“Float Backup - Off Level“ input is closed.
See Page 38.
15
DISCRETE INPUT FUNCTIONS
Float Backup - Off Level - Function 25
When a Discrete Input programmed for “Float Backup - Off Level“ closes, the Float Backup logic will be armed
and made ready to latch in one pump call for each of the “Float Backup - 1st , 2nd, 3rd On Level“ inputs that
close.
As the “Float Backup - 1st , 2nd, 3rd On Level“ inputs open, the pump calls remain latched until the Off Level input also opens, then the latch is broken on all the pump calls, and the pumps are turned off.
Note: For a two float backup system, the “Float Backup - 1st , 2nd, 3rd On Level“ inputs may be replaced with the
High Level input for the Pump Down mode, or the Low Level input for the Pump Up mode.
See Page 38.
Float Backup - 1st On Level - Function 26
When a Discrete Input programmed for “Float Backup - 1st On Level“ closes, the Float Backup logic will issue one
pump call assuming that the “Float Backup - Off Level“ is closed. See Page 38.
Float Backup - 2st On Level - Function 27
When a Discrete Input programmed for “Float Backup - 2nd On Level“ closes, the Float Backup logic will issue
one pump call assuming that the “Float Backup - Off Level“ is closed. See Page 38.
Float Backup - 3rd On Level - Function 28
When a Discrete Input programmed for “Float Backup - 3rd On Level“ closes, the Float Backup logic will issue
one pump call assuming that the “Float Backup - Off Level“ is closed. See Page 38.
Float Backup - High Level - Function 29
When a Discrete Input programmed for “Float Backup - High Level“ is closed, the High Level indicator will come
on and the High Level Alarm relay contacts will close. Also see Function 12.
Pump Down Mode (Parameter P.19 = 1)
All available pumps will be called to run when the “Float Backup - High Level“ input closes, assuming that the
“Float Backup - Off Level“ input is closed.
Pump Up Mode (Parameter P.19 = 2)
All pump operation will be disabled when the “Float Backup - High Level“ input closes.
When the “Float Backup - High Level“ input opens the “Pump Re-enable Delay” (set using Parameter P.37),
must expire before pump operation is allowed.
See Page 38.
Start Flush Cycle - Function 30
When a Discrete Input programmed for “Start Flush Cycle“ closes, the Flush Cycle will start (assuming that the
Flush Cycle Mode Parameter P.40 = 2). It does not matter how long the input remains closed, but it must be
opened to reset the logic. Typically this input is connected to contacts from an external Time Clock. See Page 21.

A Low Level float will activate the alarm. The Discrete Input used must be assigned Function 11 or 24.
A Low Level from a Level Probe input will activate the alarm. See Parameter b.01.
The Low Level Alarm will not function as a redundant pump off, except for the Low Level Alarm from
Float Backup using a Discrete Input programmed for Function 24, which will turn off the pumps.
With the Level Input Source set for the Level Probe (Parameter F.19 = 2 or 3), if not already on, the Low
Level Alarm will be activated when Electrode 10 is uncovered, unless it is disabled using Parameter
P.50.
Low Level Alarm operation may be disabled by setting Parameter P.50 = 0. This disables Low Level
Alarm operation from either the Analog Level Input (Parameter F.19 = 1) or from a Level Probe
(Parameter F.19 = 2 or 3). However, it will not disable alarm operation from a Low Level float input using a Discrete Input (Function 11 or 24), or from the Backup Low Level Probe input (See Parameter
b.01).
Fault Indication
The Fault indicator shows when there is something wrong with the system, and that there is a non-zero
Fault Code present in Parameter FLC. Please see the Fault Code Table on pages 18 - 19.
Fault Code - Parameter FLC
The current Fault Code may be viewed at Parameter FLC. Fault Codes 20 - 29 latch into memory but are
reset when the power is cycled, or may be reset by pressing the down push-button while viewing the Fault
Code. The Fault Code may also be reset remotely by setting Coil 31 in SCADA Register 40002.
Last Fault Code - Parameter LFC
The Last Fault Code (Parameter LFC) is a copy of the last non-zero Fault Code that was present in Parameter FLC. Parameter LFC is reset when power is cycled, or may be reset by pressing the down pushbutton while viewing the Last Fault Code. The Last Fault Code may also be reset remotely by setting Coil
31 in SCADA Register 40002.

ANALOG LEVEL INPUT (4-20mA Input) – CALIBRATION PROCEDURE
The following calibration is for the 4-20mA Analog Level Input (Parameter F.19 = 1) and does not apply when a 10 Electrode
Level Probe is used (Parameter F.19 = 2 or 3).
Parameters P.24 and P.25 show the Wet Well Level, while allowing the Up & Down push-buttons to be used to change the
internal numbers involved in calculating the displayed level. Therefore, the appropriate 4-20mA signal must be applied to the
Level Input during each step of the calibration procedure.
If Parameters P.24 and P.25 show 77.7 feet in the display, then Parameter F.19 is setup to follow the Level Probe input. To
calibrate the level display when using the Level Probe, the distance between the electrodes must be set on Parameter F.20,
and Parameters P.24 and P.25 are not used.
The 4-20mA Analog Level Input signal conditioning may be slowed down or speeded up using Parameter P.49.
LEVEL INPUT ZERO - Parameter P.25
This parameter is used to make the display read zero feet of water with a Wet Well Level input of 4.0mA.
Calibration Procedure:
1. Apply a 4.0mA signal to the Wet Well Level Analog Input.
(Alternate Procedure - Pull the pressure transducer or bubbler tube out of the water.)
2. Scroll to the place in the System Setup Sub-Menu where Parameter P.25 is displayed.
3. Press the Scroll / Change mode push-button. (The Wet Well Level will be displayed.)
4. Use the Up / Down push-buttons to make the display read zero feet. Note: It is slow to change at first.
5. Perform the procedure below to calibrate the “LEVEL INPUT SPAN” Parameter.
LEVEL INPUT SPAN - Parameter P.24
This parameter is used to establish the Wet Well Level (in feet) that corresponds to an analog input of 20mA.
Calibration Procedure:
1. Apply a 20mA signal to the Wet Well Level Analog Input.
(Alternate Procedure – Subject the pressure transducer or bubbler tube to a known depth of water.)
2. Scroll to the place in the System Setup Sub-Menu where Parameter P.24 is displayed.
3. Press the Scroll / Change mode push-button. (The Wet Well Level will be displayed.)
4. Use the Up / Down push-buttons to make the display read the level (in feet of water) that your 20mA signal represents. Note: It is slow to change at first.
(Alternate Procedure – Use the Up / Down push-buttons to make the display read the number of feet of water
that the pressure transducer or the end of the bubbler tube is submerged under.)
5. Repeat the procedure above for the “LEVEL INPUT ZERO” Parameter.

FLUSH CYCLE
The Flush Cycle feature is provided to periodically maximize the lift station’s discharge flow rate, to flush the
sludge build up from the bottom of the wet well and from the discharge pipe.
Flush Cycle Steps:
1. The “LEVEL” indicator begins to flash to indicate that the Flush Cycle has started.
2. Normal pump operation is suspended. Any pumps currently running are turned off.
3. Waits for the level to rise to the “Flush Cycle Start Level” set on Parameter P.43.
4. Turns on all available pumps with the Lag Pump Delay between each additional pump call.
5. Pumps the level down to the “Flush Cycle Stop Level” set on Parameter P.42.
6. Turns off all pumps.
7. The “LEVEL” indicator returns to normal to indicate that the Flush Cycle has ended.
Automatically Starting Flush Cycle:
A. Internal Time Delay - Expiration of “Delay Between Flush Cycles” set on Parameter P.41.
B. External Time Clock - Closure of a Discrete Input that is programmed to perform Function 30.
C. Programming the SCADA system to momentarily set Coil 139 in SCADA Register 40009.
Manually Starting / Stopping Flush Cycle:
Start - Press and hold the LEVEL Push-Button until the “LEVEL” indicator begins to flash.
(Momentarily set Coil 139 in SCADA Register 40009.)
Stop - Press and hold the LEVEL Push-Button until the “LEVEL” indicator returns to normal.
(Momentarily set Coil 140 in SCADA Register 40009.)
(Ends Flush Cycle even if it was started by the Time Delay or External Time Clock.)
Notes:
1. The Flush Cycle Feature only works in the “Pump Down” mode, (P.19 = 1). If Parameter P.19 is
changed to “Pump Up” mode (P.19 = 2), then Parameter P.40 will be set to “0”.
2. Use of an External Time Clock to start the Flush Cycle may be preferred, because it would provide
control over when the Flush Cycle occurs.
3. The number of pumps called to run by the Flush Cycle logic is always limited by the following:
A. Parameter P.14 - Number of Pumps Allowed to Run At the Same Time.
B. Closed Discrete Inputs that are Programmed for Pump 1 (2, 3) Disable, or All Pump Disable.
4. All backup systems must be setup so that they do not activate within the Flush Cycle operating
range set on Parameters P.42 and P.43.
5. The Low Level Float Backup (Discrete Input programmed for Function 24) will turn off all pumps upon
low level. Therefore, the Flush Cycle Stop Level must be set higher than the Low Level Float.
6. The Flush Cycle Status (Active or Inactive) may be read from Coil 141 in SCADA Register 40009.

FLOW CALCULATOR
Latest Inflow Rate - The Most Recently Determined Flow Rate into the Lift Station
The Flow Calculator determines the “Latest Inflow Rate” of liquid flowing into the lift station by observing
how long it takes for the wet well level to rise a “known distance”, while all pumps are off. Knowing the surface area of the wet well (Parameter P.46), the volume of liquid per minute flowing into the wet well is calculated. The “known distance” used in the calculation is a change in level of one foot when a Pressure Transducer is used (F.19 = 1), or the distance between electrodes (Parameter F.20) when using a Level Probe
(F.19 = 2 or 3). The “Latest Inflow Rate”, in Gallons Per Minute, may be viewed from Parameters FLH &
FLL, and is also available for SCADA at Register 40080.
Average Daily Inflow Total - The Flow Totals from the Last 7 days Averaged Together
The Flow Calculator uses the “Latest Inflow Rate” to keep a running total of how much liquid flows into the
lift station during a 24 hour period. This is done for each 24 hour period. The flow totals from the previous
7 days are all kept stored. These flow totals are added together and divided by 7. This value is displayed
as either “Gallons Per Day” or “Thousand Gallons Per Day” (See Parameter P.45). The “Average Daily
Inflow Total” may be viewed from Parameters FdH & FdL, and is also available for SCADA at Register
40081. The 7 days of flow data are also available for SCADA at Registers 40086 - 40092.
Pump Outflow Rate - The Most Recently Determined Outflow Rate of Each Pump
The Flow Calculator determines and updates the “Pump Outflow Rate” of each pump whenever it completes a pumping cycle by itself. This is done by first calculating the volume of liquid in the wet well between the “1st On Level” and the “1st Off Level”, and adding to it what flows in while the pump is running
( “Latest Inflow Rate” multiplied by the “Pump Run Time” ). This total volume of liquid is divided by the
“Pump Run Time” to arrive at the “Pump Outflow Rate”. The most recent “Pump Outflow Rate” of each
pump in Gallons Per Minute, may be viewed from Parameters F1H & F1L, F2H & F2L, F3H & F3L and is
also available for SCADA at Register 40082 - 40085.
Notes:
1. The Flow Calculator operates for “Pump Down - Empty a Tank” applications only, (Parameter P.19 = 1).
2. The “Average Daily Flow Total” is not valid until after 7 days of operation with Parameter P.44 = 1.
3. In order to have an accurate flow measurement the Flow Calculator must have recently acquired the “ Latest
Inflow Rate”. Since this is only acquired while all pumps are off, the station must periodically pump all the
way down, and turn off all pumps. Therefore, Parameter P.47 is provided to set the “Delay Before Forcing
On Another Pump (s)”. When this delay expires an additional pump or pumps are called to run, and the wet
well is pumped down. After calling the first additional pump, there is a 4 minute delay before another is
called.
4. While attempting to update the value of the “Latest Inflow Rate”, if the level rises too fast (faster than 1 foot
in 15 seconds, with Parameter F.19 = 1, or faster than one Level Probe Electrode spacing in 15 seconds,
with Parameter F.19 = 2 or 3, the logic aborts the measurement, and keeps the previously determined
value.

Notes:
1. Each controller in a SCADA system using the Modbus protocol, is assigned a unique Slave Address
so that it can be polled by the SCADA system Master using that unique Slave Address. However, if
communication is through the optional Ethernet Port, each controller will already have a unique IP
Address. When the Slave Address Parameter P.28 is set on zero, the controller will not reject messages based on the Slave Address, and it will copy the incoming Save Address for use in the Response.
2.
The Register Access Mode Parameter (P.33) is provided to prevent (when set on Read Only) malicious attempts to remotely control the pumps, or change setup parameter values. Unless greatly
needed, the Register Access Mode should be left on Read & Write.

RS232 SERIAL PORT
The RS232 serial port allows a SCADA system to communicate with the Controller using the Modbus
RTU protocol.
Setup of RS232 Serial Port
The controller’s RS232 serial port must be setup to communicate with the device it is connected to. The
Baud Rate, Parity Mode and Stop Bits Parameter values of the two devices must be set to match.
The Delay Before Response Parameter (P.32) is provided for cases where the modem needs additional
time to prepare itself before receiving a response back from the controller.

SCADA FEATURES
Level
Level Monitoring
The Level may be monitored by reading SCADA Register 40011. The value will be just what is displayed on the front
of the controller but with no decimal point. If an operator has the Controller in the Level Simulation Mode, Register
40011 will show the simulated level.
Remote Level Input
In cases where the pumps empty or fill a remote tank, the SCADA system Master may be programmed to collect the
level data from the remote tank and write the level to SCADA Register 40025 in the Controller. For the Controller to
follow the value in Register 40025, Parameter F.19 must be set on 4. Also, the value written to Register 40025 must
already be scaled into feet as it would be displayed on the front of the Controller, but with no decimal point. The
decimal point is artificially inserted by the Controller based on Parameter P.36. For example, a level of 8.6 feet
would be written as 86 (assuming that Parameter P.36 = 1).
If SCADA communication is lost, Register 40025 will no longer receive current level data. With the loss of communication the Controller will turn off all pumps and turn on the Fault indicator and place Fault Code 37 in Parameter FLC.
The Level Display will also flash and show the last value written to Register 40025. Loss of communication is established when the delay set on Parameter P.38 expires. The time delay setting on Parameter P.38 must be set long
enough so that it will not time out during the interval between normal communication events.
Discrete Inputs
The status of all the Discrete Inputs may always be read from Coils 545 - 552 in Register 40035, and Coils 561 - 564
in Register 40036, regardless of what function may be assigned to the inputs.
Discrete Inputs assigned Functions 13 - 22 (Telemetry A - L) place their status in predetermined Coils, but do not perform any other function. The status of these inputs may be read from Coils in Registers 40001, and 40008.
Discrete Inputs assigned with Functions 6 - 7, 11 - 12 and 24 - 29 perform their respective function and place their status
in predetermined Coils. The status of these inputs may be read from Coils in Registers 40001, and 40008.
Pump On / Off and Alarm Levels
The Pump On, Pump Off, High Alarm, and Low Alarm levels may be viewed and changed at Registers 40012 - 40021.
Disabling Pump Operation
To Disable a Pump set Coil 149, 150, or 151 in Register 40010. To return a pump to normal operation, clear the respective Coil.
Upon a loss of serial communication, the Pump Disable Logic will be automatically reset, and any pump that had been
remotely disabled will be re-enabled after the delay set on Parameter P.38. For this feature to work properly, the master
must poll the Controller at intervals shorter than the time set on Parameter P.38. However, if Parameter P.38 is set on
255 the pumps will remain disabled until power is lost.
Forcing a Pump On
To Force a Pump On set Coil 17, 18, or 19 in Register 40002. To return the pump to normal operation, clear the respective Coil.
Upon a loss of serial communication, the Force Pump On Logic will be automatically reset, and any pump that had been
remotely forced on will be turned off after the delay set on Parameter P.38. For this feature to work properly, the master
must poll the Controller at intervals shorter than the time set on Parameter P.38. However, if Parameter P.38 is set on
255 the pumps will remain on until power is lost.
30
SCADA FEATURES
Forcing Pump Alternation
To force Pump Alternation, momentarily set Coil 136 in Register 40009. When alternation is to be regularly performed
through the SCADA system, automatic alternation should be disabled by setting Parameter P.18 to equal 2.
Forcing Lead Pump Position
The Forcing of the Lead Pump Position may be accomplished by writing a 1,2, or 3 to Register 40022. To return to normal alternation, write a zero to the register. Setting Register 40022 does not guarantee that the pump selected will be
lead. If the pump selected as lead is disabled (by a pump disable Discrete Input), then the next available pump will be
made lead. A lead pump selector switch connected to Discrete Inputs, programmed as sequence inputs, will also override what is written to Register 40022. The setting may also be changed at Parameter P.39. The content of Register
40022 is saved in non-volatile memory. The current lead pump position may be read from Register 40023.
Remote Control of Relays
Relays that are not needed for pump control or alarm outputs, may be controlled remotely by setting their Output Function (Parameters F.31 - 35) to 2 .
Remote control is accomplished by setting or clearing Coils 25 - 29 in Register 40002.
Upon a loss of serial communication, Coils 25 - 29 will automatically be cleared after the delay set on Parameter P.38.
For this feature to work properly, the master must poll the Controller at intervals shorter than the time set on Parameter
P.38. However, if Parameter P.38 is set on 255 the relays will remain as commanded, until power is lost.
The HI Relay operates differently from the others. It has a normally closed contact, with the logic inverted. Setting Coil
25 in Register 40002 de-energizes the HI Relay closing the contact. When power is lost to the Controller the HI Relay
contact will close.
Flush Cycle
To Start Flush Cycle, momentarily set Coil 139 in Register 40009.
To Stop Flush Cycle, momentarily set Coil 140 in Register 40009.
Flush Cycle Active / Inactive status may be read from Coil 141 in Register 40009.
Flow Calculator Data
Flow Calculator Data may be read from Registers 40080 - 40092. See Pages 22 - 23.
High Level Telemetry
The High Level Alarm is generated from a comparison of the displayed Level with the High Level alarm setting. This
alarm works when Parameter F.19 is set on either 1, 2 or 3. The status of this alarm may be read from Coil 129 in Register 40009. This alarm will also set Coil 1 in Register 40001.
The High Float Alarm is generated by the closure a float switch connected to a discrete input programmed for either
function 12 or 29. The status of this alarm may be read from Coil 120 in Register 40008. This alarm will also set Coil 1
in Register 40001.
The Probe Backup High Level Alarm is generated when liquid covers the High Level Electrode of a Level Probe Input.
Parameter b.06 must be setup with the number of the Level Probe Input used to read the High Level. The status of this
alarm may be read from Coil 122 in Register 40008. This alarm will also set Coil 1 in Register 40001.

SCADA FEATURES
Low Level Telemetry
The Low Level Alarm is generated from a comparison of the displayed Level with the Low Level alarm setting. This
alarm works when Parameter F.19 is set on either 1, 2 or 3. The status of this alarm may be read from Coil 130 in Register 40009. This alarm will also set Coil 2 in Register 40001.
The Low Float Alarm is generated by the closure a float switch connected to a discrete input programmed for either
function 11 or 24. The status of this alarm may be read from Coil 128 in Register 40008. This alarm will also set Coil 2
in Register 40001.
The Probe Backup Low Level Alarm is generated when liquid uncovers the Low Level Electrode of a Level Probe Input. Parameter b.01 must be setup with the number of the Level Probe Input used to read the Low Level. The status of
this alarm may be read from Coil 121 in Register 40008. This alarm will also set Coil 2 in Register 40001.
Fault Codes
The Fault Code (Parameter FLC) may be read from Register 40047.
The Last Fault Code (Parameter LFC) may be read from Register 40048.
The Fault Code and the Last Fault Code may be reset by setting Coil 31 in Register 40002.
Elapsed Time Meters
Pump 1-3 Elapsed Time Meters may be read from Registers 40003 - 40005. The values read from these registers are
intended for use in comparing the pump run time of one pump with the run time of the other pumps at the station, for the
purpose of checking for uneven run times. (Uneven run times is an indication of a maintenance problem with one of the
pumps.) Periodically the comparison of run times should be made and the registers should reset to zero. The ETM data
is stored in non-volatile memory just prior to a total loss of internal 5V power, so the data is not lost during a power outage. (However, if the serial port is being polled as a power outage occurs, the most recent data may occasionally be
lost.) To reset one of the ETMs to zero, momentarily set the respective Coil (21 - 23) in Register 40002.

SCADA TROUBLESHOOTING
Communication Activity Indicator
The Communication Activity Indicator (Parameter d.07) may be used to help troubleshoot communication issues.
It typically pulses from “0” to “1” momentarily to indicate that the master is sending a message. It may stay “1” if there is
very little time between messages.
It does not indicate that a valid communication has occurred, only that there is activity on either the RS232 port or the
Ethernet port.
When using the Ethernet Port, the Ethernet Board logic will block messages with the wrong IP Address, or when there
are setup issues with the Ethernet Port. For the Activity Indicator to be pulsed, the message must be accepted and
passed through the Ethernet Board to the Main Controller Board.
Address of Last Slave Polled by Master
The Address of Last Slave Polled by Master (Parameter d.08) may be used to help troubleshoot communication issues.
When using the RS232 port, it shows the address of the last slave that was polled by the master.
When using the Ethernet Port, the Ethernet Board logic will block messages with the wrong IP Address, or when there
are setup issues with the Ethernet Port. For Parameter d.08 to show the slave address, the message must be accepted
and passed through the Ethernet Board to the Main Controller Board.
Record of Last Modbus Message
If the Slave Address is acceptable and the message does not have an Overrun Error (FLC = 1), Time Out Error (FLC =
2), Framing Error (FLC = 13), or Noise Error (FLC = 14) then the entire Modbus message will be present in data Parameters d.08 - d.86. If the Slave Address is not acceptable or if any of these errors are encountered, the rest of the
message is rejected and does not show up in Parameters d.08 - d.86. If the entire message is received (present at Parameters d.08 - d.86), it may fail the Checksum Test (FLC = 4), have an Invalid Modbus Function Code (FLC = 5), or
have one of 7 other faults (FLC = 6, 7, or 31 - 35). Failing any of these tests will cause the logic to not perform the Function and not send out a Response.
Communication Fault Codes
Communication Faults will often generate a Fault Code (Parameters FLC and LFC) that may be used to help determine
the cause of a communication problem. When this occurs the Fault Indicator will come on.
A valid communication after a Fault will zero Parameter FLC, and will make the Fault Indicator turn off, but the Fault
Code will still be available at Parameter LFC. See the Fault Code Table for the description of the communication Fault
Codes 1 - 7, 13 - 14, 31 - 35 and 37.

FLOAT BACKUP EXAMPLE - Pump Down
Notes:
1. Pump Down Applications (Parameter P.19 = 1)
Two Float Backup - A simple two float backup system can be made using an Off float and a High float.
High Level Input - Closure of the Float Backup High Level input will cause all pumps to be called to run, provided the
Off float input is closed. The Discrete Input used for the High Level must be set on Function 29.
Low Level input - Closure of the Low Level input will disable all pump operation. When the Low Float input opens, a
delay prevents the immediate calling of the pumps. This delay is set on Parameter P37. The Discrete Input used for
the Low Level must be set on Function 24.
Float Type - For Pump Down applications the Off, 1st , 2nd , and 3rd On, and High floats must be normally open float
switches that close as the level rises above the float. The Low Level float must close as the level drops below the
float.
2. Pump Up Applications (Parameter P.19 = 2)
Two Float Backup - A simple two float backup system can be made using an Off float and a Low float.
Low Level Input - Closure of the Float Backup Low Level input will cause all pumps to be called to run, provided the
Off float input is closed. The Discrete Input used for the Low Level must be set on Function 24.
High Level Input - Closure of the High Level Float Switch will disable all pump operation. When the High Float input
opens, a delay prevents the immediate calling of the pumps. This delay is set on Parameter P37. The Discrete Input
used for the High Level must be set on Function 29.
Float Type - For Pump Up applications the Low, Off, 1st , 2nd , and 3rd On floats must be normally closed float switches
that close as the level drops below the float. The High Level float must close as the level rises above the float.
3. The FAULT light comes on and Fault Code 16 is generated, when a pump is called to run by the Float Backup system.
