ParametersThe default parameter settings are enough for starting the pump station. The settings canbe fine-tuned for applications that require additional performance. For more information,see Adjust the parameters to fine tune the process (page 27).Parameters regarding the motor can be set independently of application while parametersregarding the process are application-dependent.

Start the systemThe system require that the pumps are equipped with FLS, thermal contacts and aasynchronous motor that have been installed using screened cables.1. Energize the drive.2. Start the drive by pressing the on key.

The system runs and pumps water in the auto mode, locally, and using pre-set values.

To start systems that use LSPM motors, see Start the system with LSPM motors (page 41).

Operating modeAuto

The drive controls the process using the current settings in the unit.The drive alternates between energy efficient operation and sump cleaning operations.The drive regulates the pump so that the water level always follows the parameter values inboth operations.

HandThe operator controls the process manually using the user input keys. The pump does notuse the level sensors in this mode and does not perform cleaning functions.



21

The operator control the pump by setting the speed by increasing or decreasing the motorfrequency.

The drive automatically switches back to auto-mode after 10 minutes.

Energy efficient operationThis is the mode that SRC 311 uses as default. During this mode the SRC 311 is constantlyconducting calculations to find the best optimal speed for the pump so that it is used in themost energy efficient way.

The pump starts pumping when the start level is reached. The pump runs at maximumspeed for a few seconds, then it slows down to optimal speed. The pump stops at the stoplevel and waits until the start level is reached again.

The optimal speed can be set to a fixed value manually. This value have to be calculationafter an analysis have been performed of the system.

High inflowDuring high inflow conditions such as rain the pump might not manage to empty the sumpusing the optimal speed settings. The SRC 311 will then raise the speed until the outflowmatches the inflow.



Very high inflowIn extreme cases the pump cannot empty the sump by itself even at maximum capacity. Ifthere are other pumps in the system then this is when they also start pumping. If the level isstill increasing SRC 311 sends an alarm when the level reaches the high level sensor.

ValuesSetting Value Description

Start level (P1–15) Varies depending on size, see tablebelow.

Sump level where the pump willstart. Cannot be lower than the stoplevel or higher than the high levelsensor.

Stop level (P1–16) Varies but must not be lower than thepumps suction inlet.

Sump level where the level sensor ishung and pump will stop pumping.

High level 20 cm above the Start level. Level for the high level sensor.

High level alarm level Varies but must be installed 250 mm(9.84 in.) above the start level.

The sensor is hung at the desiredtriggering height.

Energy efficient speed settling time Variable time (6 – 10 seconds). The time between pump start andwhen it reaches optimal speed.

Start flush time Variable time (6 – 8 seconds). The time when the pump runs atmaximum speed. Varies dependingon varied inflow, sump size etc.

This function is used to spread the wear evenly over several pumps. The function starts thepumps every other time, in a two pump station, selects a random start level with in the 20cm range once every 24 hours. The pump with the lowest start level will be the one thatstarts and the other pumps will be inactive during this 24 h period.



23

When there is a high inflow and the one pump does not manage to empty the sump, noteven when it is working at maximum capacity the other pumps will also start pumping.When the water level increases to the next pump's start level, that pump will start, and thenthe next, and so on, until the water level stops rising.

During normal operation two or more pump can get the same or very similar startinglevels. Both pumps will run simultaneously during the next period. This happens during 3 –5% of total running time.

Pump blocking and I/O alternation

I/O alternationThe pumps alternate and do not run simultaneously. The other pumps only starts duringhigh inflow situations that the one pump cannot handle by itself.

To enable I/O alternation, connect "Pump running" output of pump 1 to "Pump blockinput" to pump 2, and vice versa. Set parameter P1-17 Cleaning mode to 0-3.

Pump blockingIt is possible to block pumps that are used for backup from running at the same time as themain pump.

If one or more pumps have been installed for redundancy purposes, but cannot runsimultaneously due to electrical or mechanical issues, then block the backup pump.

The run signal from one pump is connected to the block terminal of another pump,together with the feature "Full pump block" in parameter P1–17.Cleaning mode Whenthese settings are made, only one pump can operate at the time, even if the inflow ishigher than one pump can handle. The pumps will alternate over time.

CleaningThe cleaning setting are changed in the P1–17 parameter.

Setting Value Description

All off 0 (default) No cleaning functions are active

Sump cleaning on 1 Only sump cleaning is active

Pump cleaning on 2 Only impeller cleaning is active

All cleaning on 3 Both cleaning functions are on

F.P.B and Sump on 5 Sump cleaning and full pump blockis active

F.P.B and impeller on 6 Impeller cleaning and full pumpblock is active

Everything on 7 All cleaning and full pump block isactive

Sump cleaningThis function cleans the sump by pumping down the water level until the pump is snoring.If the snoring detection is malfunctioning the function will stop after a predetermined time.Sump cleaning occurs ones every 24 h , if the sump cleaning function is activated inparameter 1-17.

Pump cleaningThis function will clean the impeller. The function is triggered when continuous currentexceeds the nominal current or on peak current much higher than the nominal current.



The ramp times for the pump cleaning function are shared with other ramp times in thesystem, meaning the pump cleaning function will not have its own ramp times.

Pipe cleaningThe pump cleans the pipes by increasing the flow through the pipes to avoidsedimentation and pipe clogging. There is no dedicated function for this but the pipes arecleaned during every new cycle the High-low level sump pump control (page 22) starts andduring sump cleaning.

Energy efficient speed finderThis function calculates the optimal speed that is used by the High-low level sump pumpcontrol (page 22).



25

The function slowly calculates the optimal speed and depending on the system thecalculations may take weeks before the optimal speed is found. The optimal speed willchange with 0.5 Hz per day if the pump is pumping.

The optimal speed is controlled by the parameter P1-18 “Optimal frequency”. To changethe optimal speed, simply set parameter P1-18 “Optimal frequency” to the desired positivespeed, between parameter P1-01 ”Maximum frequency” and parameter P1-02 ”Minimumfrequency”. To deactivate the energy efficient speed finder function and set a fixed optimalspeed, set parameter P1-18 “Optimal frequency” to a negative speed. For example, settingparameter P1-18 “Optimal frequency” to -38.0 Hz would mean that the pump always wouldrun at 38.0 Hz during energy efficient operation.

TroubleshootingAlarm and monitoring functions

The monitoring functions are active in Auto mode and when an alarm is active it is visible inthe SRC 311 display. The alarm shows as a sum alarm on a open relay (Relay 1, terminal 14and 15) and as an alarm register accessible through fieldbus, Modbus RTU.

Alarm codeThe alarm code in P1-19 “Alarm state” is a sum of all active alarms. The alarm valuesare shown in following table.

Table 2: Pump and process alarm

Alarm Bit Value

No error - 0

High level (reset) 0 1

Pump over temperature (reset) 1 2

Pump leakage (reset) 2 4

Sensor error 3 8

Alarm active 4 16

Activation and resetAll alarms stay active until they are reset. When SRC 311 do not show any alarms itremember the highest sum of all alarms that has been active without being reset. Allalarms have a 4 seconds delay to avoid nuisance alarms.

If an alarm is reset but still active, then the alarm disappears from the sum alarm anddisplay but available in the alarm state register. The alarm state register shows that thealarm is reset. Each item in the alarm register corresponds to one alarm, and the lastinformation in each item shows if the alarm is reset or if it is a new alarm.

For example, if the alarms "Sensor error" and "High level" are active, the alarm code will be8 (Sensor error) + 1 (High level) + 16 (Alarm active) = 25. If the errors are gone and thealarm is reset, the alarm code will be "0". If the "High level" alarm still is active, the alarmcode will be "1" after reset.

The alarms are reset by:

• Digital input signal (Terminal 3, 8-30V DC)• Pressing the OFF key• Writing 3456 to the alarm state register P1-19 “Alarm state” using Modbus RTU

Sump and pump monitoringThe drive monitors the pumps two sensors FLS and thermal contactor.

The high sump level alarm is triggered by the digital level switch sensor or by the analoglevel sensor. The pump automatically starts pumping at maximum speed for 30 secondsbefore it returns to normal operation.

The sensor error alarm is triggered if the digital level switch triggers at the same time asthe analog level sensor reports that the water level is below the start level. This indicatesone of the following:

• The analog level sensor is not connected.• The analog level sensor is connected but does not work.• The analog level sensor is connected but not in the sump.• The digital level switch is hung to low in the sump.

CommunicationPump and process alarms are communicated externally using fieldbus (Modbus RTU) anda sum - alarm on relay 1, terminal 14 and 15.

For details regarding alarm codes, registers and terminals, see Fieldbus communication(page 40). When a process alarm, from the pump or the sump, is triggered the relevantregister contain the Modbus alarm code and the sum alarm on the relevant relay terminal.

If several alarms are active at the same time, then the Modbus register contain the alarmcode for that combination of alarms. The panel also displays the relevant alarm code. If analarm is reset and the alarm is no longer triggered the alarm output also goes back tonormal. No additional reset is required.

Fault codesThe fault codes are displayed when the drive has tripped. A log of the last 4 trips is storedin P0-13 .

Cable connections• The motor cable must be screened and earthed (grounded) at both ends to prevent

undesired electrical interference from the variable frequency drive (range between1MHz and 10MHz).

• Ensure that all control conductors are twisted together until they reach the connectionpoint. Make sure that they stay twisted together after the cable have been peeled atthe connection point.

• If possible place the control conductors in a separate cable channel in the controlpanel to avoid coupling to other interference sources.

• Separate signal and protective earth (ground) from each other. The two earth (ground)connections must be connected together at the main supply point since parallel earth(grounding) is not allowed.

• If ground loops, current or magnetic disturbances occur in the cable screen, then openthe screen connection in the control panel and connect a capacitor in series betweenthe screen and ground (for example, 0.5μf, 1kV).

• The ground system must have one system ground, where all ground connections areconnected from the control panel and various control units. Avoid earth (ground) loopsthrough gland plates and cable gland bonding and ensure that there is no potentialdifference in the ground system.

• Monitor cables must be segregated from all mains cables by at least 30 cm (11.8 in) byuse of separate metal conduits and/or cable trays earthed (grounded). Monitor cablesmust be segregated from all motor cables by at least 50 cm (19.7 in) by use of separatemetal conduits and/or cable trays grounded. Monitor cables must not cross powercables unless necessary and then only at 90 degree angles.
