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), 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 con-
nected to. This feature is for alarm and telemetry only and will not function as a redundant pump call. See SCADA notes page 26.
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 con-
nected to. This feature is for alarm and telemetry only and will not function as a redundant pump off. See SCADA notes page 26.
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.

L.01 Electrode 1 Status Value
Level Probe Electrode Status Values
Normal Range when Un-Covered: 240 - 255
Normal Range when Covered by Typical Sewage: 55 - 70
Notes:
1. The Controller compares each of the Electrode Status Values with what is set on
Parameter F.22. When the value drops below the setting on Parameter F.22, the
Controller logic considers the Electrode to be covered by liquid.
2. Parameters L.01 - L.10 are also used to diagnose Out of Sequence Faults (Fault
Codes 21 - 29).
3. For the status of the Level Probe inputs see Coils 583 - 592 in SCADA Register
40037.

Level Probe Test Signal Status Normal Range: 230 - 254
Note: This is a Measure of the ±8V, 60Hz Square Wave Sent Out to Each Electrode to read the level. If the value is below
210, a malfunction has occurred in the circuit that provides the Square Wave used to read the level. In this case the wet
well level display will show zero, the Fault indicator will be turned on, and Fault Code 20 will be generated.

Notes:
1. Unless there is some special circumstance that requires a more complicated
pump call sequence, this is the sequence that should be used.
2. Parameter P.17 must be used to select either First On Last Off or First On
First Off.
3. Discrete Inputs programmed as Pump 1-3 Disable inputs may be used to
disable pumps.
4. Discrete Inputs programmed as Sequence Inputs 1-3 may be used to set
the lead pump.
5. Parameter P.39 may be used to set the lead pump.
6. A Discrete Input programmed for External Alternation (Function 5) may be
used to force alternation. When this feature is used, Automatic Alternation
would normally be disabled by setting Parameter P.18 to Disabled.
7. If connected to a SCADA system, alternation may be initiated by momentar-
ily setting Coil 136, or by forcing the lead pump by writing to Register 40022
(Same as Parameter P.39).
Notes:
1. This sequence is used when it is required that pump 1 always be lead pump.
This sequence keeps pump 1 on, when the other pumps are called to run.
2. Parameter P.17 must be used to select either First On Last Off or First On
First Off.
3. Discrete Inputs programmed as Pump 1-3 Disable inputs may be used to
disable pumps.
4. For Triplex applications Discrete Inputs programmed as Sequence Inputs 2
-3 may be used to set the lead pump.
5. For Triplex applications Parameter P.39 may be used to set the lead pump
among pumps 2 and 3.
6. If pump 1 is disabled another pump will be called in its place.
7. A Discrete Input programmed for External Alternation (Function 5) may be
used to force alternation. When this feature is used, Automatic Alternation
would normally be disabled by setting Parameter P.18 to Disabled.
8. If connected to a SCADA system, alternation may be initiated by momentar-
ily setting Coil 136, or by forcing the lag pump by writing to Register 40022
(Same as Parameter P.39).

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
Lag Pump Delay, the other pump is turned on.
2. For Triplex applications Parameter P.17 must be used to select either First
On Last Off or First On First Off.
3. Discrete Inputs programmed as Pump 1-3 Disable inputs may be used to
disable pumps.
4. For Triplex applications Discrete Inputs programmed as Sequence Inputs 2-
3 may be used to set the lead pump.
5. For Triplex applications Parameter P.39 may be used to set the lead pump
among pumps 2 and 3.
6. If pump 1 is disabled, another pump will Not be called in its place. The 1ST
Pump On/Off Level parameters are dedicated to pump 1 and will not call
another pump.
7. A Discrete Input programmed for External Alternation (Function 5) may be
used to force alternation. When this feature is used, Automatic Alternation
would normally be disabled by setting Parameter P.18 to Disabled.
8. If connected to a SCADA system, alternation may be initiated by momentar-
ily setting Coil 136, or by forcing the lag pump by writing to Register 40022
(Same as Parameter P.39).
Notes:
1. This sequence is used when it is required that pumps 1 and 2 alternate
among themselves and pump 3 must always be called last.
2. For Triplex applications Parameter P.17 must be used to select either First
On Last Off or First On First Off.
3. Discrete Inputs programmed as Pump 1-3 Disable inputs may be used to
disable pumps.
4. Discrete Inputs programmed as Sequence Inputs 1-2 may be used to set the
lead pump.
5. Parameter P.39 may be used to set the lead pump. Setting Parameter P.39
on 3 has no effect.
6. If either Pump 1 or 2 is disabled, then Pump 3 will be called to take its place.
7. A Discrete Input programmed for External Alternation (Function 5) may be
used to force alternation. When this feature is used, Automatic Alternation
would normally be disabled by setting Parameter P.18 to Disabled.
8. If connected to a SCADA system, alternation of Pumps 1 and 2 may be initi-
ated by momentarily setting Coil 136, or by forcing the lead pump position
by writing to Register 40022 (Same as Parameter P.39).

1. This sequence is used when no alternation is required and when pump 1
should normally be lead pump. Other pumps may be made lead by setting
Parameter P.39.
2. Discrete Inputs programmed as Pump 1-3 Disable inputs may be used to
disable pumps.
3. Discrete Inputs programmed as Sequence Inputs 1-3 may be used to set the
lead pump.
4. Parameter P.39 may be used to set the lead pump.
5. The Pump Stop Mode (Parameter P.17) has no effect on this sequence.
6. Automatic Alternation Enable/Disable (Parameter P.18) has no effect on this
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).
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 de-
creases, 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
sequence.
8. The External Alternation feature will not function when using this sequence.
9. The On Generator (Parameter P.15) has no effect on this sequence.

High Level Alarm
• Upon a High Level Alarm, the indicator will come on and the relay contacts will close.
• A High Level Alarm is delayed for ten seconds after power is applied.
• The High Level Alarm relay contacts will be closed when there is no power on the controller.
• The moment electrical power is applied to the controller, the High Level Alarm relay contacts open.
• The High Level Alarm relay contacts will close if there is a complete failure of the controller.
• The High Level Alarm will be activated as the level rises to or above the High Level Alarm level setting.
• A High Level float will activate the alarm. The Discrete Input used must be assigned Function 12 or 29.
• A High Level from a Level Probe input will activate the alarm. See Parameter b.06.
• With the Level Input Source set for the Level Probe (Parameter F.19 = 2), if not already on, the High
Level Alarm will be activated when Electrode 1 is covered with liquid.
Low Level Alarm
• Upon a Low Level Alarm, the indicator will come on and the relay contacts will close.
• A Low Level Alarm is delayed for 90 seconds after power is applied.
• The Low Level Alarm relay contacts will be open when there is no power on the controller.
• The Low Level Alarm will be activated when the level is at or below the Low Level Alarm level setting.
• 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), 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). 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 13 - 14.
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.
The Last Fault Code (Parameter LFC) is a copy of the last non-zero Fault Code that was present in Pa-
rameter FLC. Parameter LFC is reset when power is cycled, or may be reset by pressing the down push-
button 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).
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 repre-
sents. 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.
Notes:
1. Level Display Span is what is displayed with a 20mA Level Input.
2. Parameter P.36 is used to set the decimal point position.
3. To find the Level Input Span Setting for other transducers use the following equation:
Pressure (psi) x 2.309 = Level (feet of water)

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 may be started by one of the following ways:
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. Pressing and holding the LEVEL Push-Button until the “LEVEL” indicator begins to flash.
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.
Manually Starting / Stopping Flush Cycle:
Start - Press and hold the LEVEL Push-Button until the “LEVEL” indicator begins to flash.
Stop - Press and hold the LEVEL Push-Button until the “LEVEL” indicator returns to normal.
(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 1-3 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.

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 sur-
face area of the wet well (Parameter P.46), the volume of liquid per minute flowing into the wet well is calcu-
lated. The “known distance” used in the calculation is a change in level of one foot when a Pressure Trans-
ducer is used (F.19 = 1), or the distance between electrodes (Parameter F.20) when using a Level Probe
(F.19 = 2). 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 com-
pletes a pumping cycle by itself. This is done by first calculating the volume of liquid in the wet well be-
tween 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), 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 mes-
sages based on the Slave Address, and it will copy the incoming Save Address for use in the Re-
sponse.
2. The Register Access Mode Parameter (P.33) is provided to prevent (when set on Read Only) mali-
cious attempts to remotely control the pumps, or change setup parameter values. Unless greatly
needed, the Register Access Mode should be left on Read & Write.
