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 – 4TH 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 additional pumps are present set the
3RD On and 4TH On Levels, to operated from Electrode 1 by setting Parameter b.05 = 1, and b.06 = 1.
4. If a Backup High Level Alarm is desired, set Parameter b.07 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 32.
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 33.
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.

Parameter Data Description
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.
L.02 Electrode 2 Status Value
L.03 Electrode 3 Status Value
L.04 Electrode 4 Status Value
L.05 Electrode 5 Status Value
L.06 Electrode 6 Status Value
L.07 Electrode 7 Status Value
L.08 Electrode 8 Status Value
L.09 Electrode 9 Status Value
L.10 Electrode 10 Status Value
L.11 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.

PUMP CALL SEQUENCE - Setup Parameters
9
The following is a description of each of the Setup Parameters used to establish the Pump Call Sequence:
Note: Discrete Inputs programmed with Functions 1-4, 6-7, 9-12, and 13-16 are also available to establish or modify the
Pump Call Sequence. See the description of these Discrete Input Functions on pages 14-16.
Number of Pumps Present - Parameter P.13
This Parameter establishes how many pumps are available at the Lift Station to perform level control.
Simplex (1 pump) Duplex (2 pumps) Triplex (3 pumps) Quadraplex (4 pumps)
Number of Pumps Allowed to Run at the Same Time - Parameter P.14
In cases where there is an inadequately sized discharge pipe, or inadequate electrical power, running all available
pumps at the same time may be a problem. This Parameter is used to set an upper limit on the number of pumps
called to run at the same time. If there is no need for this feature P.14 may be left on it’s default value of 4.
Parameter Default Value Setting Definitions
P.13 4 Number of Pumps Present
1 = 1 Pump 2 = 2 Pumps 3 = 3 Pumps 4 = 4 Pumps
Parameter Default Value Setting Definitions
P.14 4 Number of Pumps Allowed to Run at the Same Time
1 = 1 Pump 2 = 2 Pumps 3 = 3 Pumps 4 = 4 Pumps
Number of Pumps Allowed to Run On Generator - Parameter P.15
In cases where the Emergency Generator is not sized large enough to run all the available pumps, this Parameter
is used to set an upper limit on the number of pumps called to run on the Generator. There must be a contact from
the Transfer Switch connected to one of the Controller’s Discrete Inputs and it must be programmed for Function 7.
If there is no need for this feature Parameter P.15 may be left on it’s default value of 4.
Parameter Default Value Setting Definitions
P.15 4 Number of Pumps Allowed to Run On Generator
1 = 1 Pump 2 = 2 Pumps 3 = 3 Pumps 4 = 4 Pumps
Alternator Sequence Mode - Parameter P.16
This Parameter is provided to allow the Controller to accommodate a variety of special sequence requirements.
Parameter Default Value Setting Definitions
P.16 1
Alternator Sequence Mode
1 = Standard Alternation See Page 11.
2 = Pump 1 Always Lead - Stays On With Other Pumps See Page 11.
3 = Pump 1 Always Lead - Turns Off With Other Pumps See Page 12.
4 = Split Alternation - Pumps 1&2, and Pumps 3&4 See Page 12.
5 = Fixed Sequence - Pump 1 Always Lead See Page 13.
6 = Stepped On/Off - Only One Pump Runs at a Time See Page 13.

10
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 6.)
Parameter Default Value Setting Definitions
P.17 2 Pump Stop Mode 1 = First On Last Off 2 = First On First Off
Parameter Default Value Setting Definitions
P.18 1 Automatic Alternation 1 = Enabled 2 = Disabled
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 1-2-3-4. Parameter P.39
may also be changed by writing a 0,1,2,3 or 4 to SCADA Register 40022.
Parameter Default Value Setting Definitions
P.39 0 Forced Lead Pump Position SCADA Register 40022
0 = Normal Alternation 1(2,3,4) = Pump 1(2,3,4) as Lead
Time Based Alternation - Parameter P.51
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 Default Value Setting Definitions
P.51 0 Time Based Alternation Time Clock Range: 1 - 255 1/6 hour
0 = Disabled 1 = 1/6 hour 6 = 1 hour 48 = 8 hours 144 = 24 hours

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.

6. For Triplex and Quadraplex applications Parameter P.39 may be used to set
the lead pump.
7. 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.
8. A Discrete Input programmed for External Alternation (Function 6) may be
used to force alternation. When this feature is used, Automatic Alternation
would normally be disabled by setting Parameter P.18 to Disabled.

ily setting Coil 136, or by forcing the lag pump by writing to Register 40022
(Same as Parameter P.39).

should normally be lead pump. Other pumps may be made lead by setting
Parameter P.39.

this sequence.
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 1-4 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 Call Pump 1-4 Last will not function when
using this sequence.
5. Discrete Inputs programmed as Sequence Inputs 1-4 will not function when
using this sequence.
6. Parameter P.39 has no effect on this sequence.

11. 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

14
Pump 1 (2, 3, 4) Disable - Functions 1 - 4
When a Discrete Input programmed as a “Pump 1 (2, 3, 4) Disable” is closed, the respective pump will be dis-
abled (not allowed to run) and skipped over in the pump call sequence. If the respective pump had been running
when the input closed, it would be turned off immediately.
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.
External Alternation - Function 6
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.
Sequence Input 1 (2, 3, 4) - Functions 9 - 12
When a Discrete Input programmed as a “Sequence Input 1 (2, 3, 4) ” 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 - 4 (assuming Parameter P.16 = 1). See page 37 for connection diagrams.
The following is a description of the Functions that may be assigned to the Discrete Inputs using Parameters F.01 - F.18:
Notes: 1. All Discrete Inputs are originally programmed with default Functions, but they may be changed at any time using
Parameters F.01 - F.18.
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.
DISCRETE INPUT FUNCTIONS
On Generator - Function 7
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.
Level Freeze - Function 5
In cases where the Emergency Generator is not sized large enough to run all the available pumps, closing a Dis-
crete Input programmed for “On Generator” will limit the number of pumps called to run to the number preset us-
ing Parameter P.15. Typically contacts from the Transfer Switch are connected to this input.
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 32 - 38, or Level Probe Backup using
Parameters b.01 - b.07. 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.
All Pump Disable - Function 8

15
DISCRETE INPUT FUNCTIONS
When a Discrete Input programmed for “Call Pump 1 (2, 3, 4) Last” is closed, it assigns the respective pump to
standby status, where it will always be called to run last.
If more than one but not all of the pumps are assigned to standby status, they will all be available to run if needed,
but in a fixed order, and always after the pumps not assigned standby status.
If all the pumps are assigned to standby status, then alternation will occur normally, as though none of them were
assigned standby status.
Telemetry E - D - Functions 19 - 30
Low Level Alarm - Function 17
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 32.
High Level Alarm - Function 18
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 38.
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 28.
Call Pump 1 (2, 3, 4) Last - Functions
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 32 - 38, or Level Probe Backup using Parameters
b.01 - b.07.
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.
Normal Pump Operation Disable - Function 31
Float Backup - Low Level - Function 32
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 17.
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 42.

16
DISCRETE INPUT FUNCTIONS
Float Backup - Off Level - Function 33
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, 4th On Level“ inputs that
close.
As the “Float Backup - 1st , 2nd, 3rd, 4th 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, 4th 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 42.
Float Backup - 1st On Level - Function 34
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 42.
Float Backup - 2st On Level - Function 35
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 42.
Float Backup - 3rd On Level - Function 36
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 42.
Float Backup - 4th On Level - Function 37
When a Discrete Input programmed for “Float Backup - 4th On Level“ closes, the Float Backup logic will issue
one pump call assuming that the “Float Backup - Off Level“ is closed. See Page 42.
Float Backup - High Level - Function 38
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 18.
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 42.
Start Flush Cycle - Function 39
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 22.

SYSTEM STATUS
17
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 18 or 38.
• A High Level from a Level Probe input will activate the alarm. See Parameter b.07.
• With the Level Input Source set for the Level Probe (Parameter F.19 = 2 or 3), 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 17 or 32.
• 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 32, 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 17 or 32), 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.
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.
Last Fault Code - Parameter LFC
Power Indication
The Power indicator is normally on, but it will alternately flash with the Fault indicator, when the All Pump
Disable Discrete Input (Function 8) is closed. Fault Code Parameter FLC will also show Fault Code 18.

must be at least 0.5 feet apart with P.36 = 1, or 5 feet with P.36 = 0, or 0.05 feet with P.36 = 2.)
12 VFD Speed Reference Setup Fault - Level at Minimum Speed and Level at 100% speed are backwards.
13 Communication Fault - The UART detected a Framing Error reading the incoming message. It did not find Stop

One of the Pump On or Pump Off level control Parameters (or Parameters P.21, P.22, P.42, or P43) is set too
low. One of them is set in the part of the display range that is artificially created by the Level Offset Parameter
F.21. See page 5 for a description of Parameter F.21. All level control Parameters must be set higher than what
is set on Parameter F.21.
20 Level Probe Fault - Test Signal Status Below Normal Range. See Parameter L.11 on page 7.
Notes:
1. Level Probe Fault Codes 21-29 must be present for at
least 60 seconds for the fault to be latched into memory.
2. To reset the fault, scroll to and view Parameter FLC. Re-
cord the Fault Code, then press the Down push-button
while viewing the Fault Code. Cycling power to the con-
troller will also reset the Fault Code.
3. The analog value associated with each of the Level Probe
Electrodes may be viewed from Parameters L.01 - L.10.
