MultiSmart Pump Station Manager & RTU

Every Time the Pump Starts I see a Contactor Auxiliary Fault on the MultiSmart iPSM

The default wiring diagram for the Pump Controller usually includes feedback from the contactor to indicate that the pump has started.  If you have followed the wiring diagram correctly, then the MultiSmart unit is indicating one of the following:

  • That the contactor has failed - check contactor
  • The pump output relay is not wired to the contactor - check wiring
  • The output relay has been reconfigured 
  • The output relay has a problem - check the System Log Info screen

There is No Level Displayed on My MultiSmart iPSM 

First, check that the I/O module is reading the input(s) correctly. From the main operator screen, press Info, I/O, choose a board (typically Top Board), then select the relevant input type.

Analog level device

If you are using a 4-20mA level device, choose Analog Input. If the input is at 0mA, then one of the following is the case:

  • the level device is not properly connected

  • the level device is not properly configured

  • there is a problem with the MultiSmart I/O card - Problems with I/O cards can often be seen in the system log in Info, System Log

If the input is reading between 4-20mA, the pump control module is not configured to use this level device.  From the main operator screen, press Settings, I/O Faults & Level, Level Devices.  The primary level device will probably show a different analog input or a Multitrode Probe (i.e. it has not been correctly configured).  You can go back through the Setup Wizard which will give you a completely new configuration, or you can simply configure the level device using this Level devices screen.  

Probe

If you are using a Multitrode Probe, choose Digital Inputs.  Check that some of the sensors are covered (the value should be showing as ON).  If none of the Probe sensors are reading ON, then one of the following is the problem:

  • You have not connected the Probe

  • The Probe is not covered with conductive liquid

  • There is no ground (earth) return for the Probe

  • There is a problem with the MultiSmart I/O card - Problems with I/O cards can often be seen in the system log in Info, System Log

If the DINs are showing an ON status, then the pump control module is not configured correctly.  From the main operator screen, press Settings, I/O Faults & Level, Level Devices.  The primary level device needs to be changed to Probe - or the correct sensors needs to be assigned (e.g. when the Probe is made the level device, by default, DIN2-11 are configured for the 10 sensors.  If you have wired the Probe to different sensors you can rewire or change the sensor configuration).

You can also go back through the Setup Wizard which will give you a completely new configuration, or you can simply configure the Probe using this Level Devices screen.  

How Do I Set Up Communications for the MultiSmart iPSM?

The RTU module of the manual has information on setting up Communiations.

Note that, in some default configurations, DNP3 Slave and MODBUS Slave would point to the same channel (channel 1). v1.4.1 onwards creates a Fault and disables MODBUS if both are pointing to the same channel.

You can navigate to the configuration for MODBUS to activate/deactive the Slave or to change the comms channel:

Activating/deactivating MODBUS Slave:  Settings - Advanced - MODBUSSlave - Slave01 (or the correct slave if more than one configured) - Session - Slave Active.

Similarly for DNP3 (choose DNP3 slave instead of MODBUS Slave).

Changing the channel: Settings - Advanced - MODBUS Slave - Slave01 (or the correct slave if more than one configured) - Session - Comms Channel.

Similarly for DNP3 (choose DNP3 slave instead of MODBUS Slave).

Please contact us if you have a specific problem that you cannot resolve.

How Do I Clear a Probe Error on the MultiSmart iPSM?

I/O Probe Error won't go away (v1.0-v1.1)

The I/O Probe Error occurs when one or more of the Probe segments appears faulty.  This happens when a sensor higher in the well is covered (conductive to ground), but one or more sensors lower down are not covered (conductive to ground).

The MultiSmart unit sees this as an error. You can check which segment is faulty by looking at the raw I/O data. From the main operator screen, press Info - I/O - Top Board (or whichever board your Probe is connected to), Digital Inputs. You can see which Digital Inputs are ON and which are OFF.

v1.0 - v1.1 do not clear the fault condition when the level goes below the faulty sensor.

Although this is logical - because the fault condition is probably still there - it is a difficult problem to clear in the field (i.e. If you have found a simple wiring problem and rectified it, you have to wait until the level in the well rises above the previously faulty sensor before the fault is verified as cleared, which can be inconvenient.)

v1.2 onwards - when the level drops below the fault sensor, the fault will go inactive (i.e. awaiting a reset). This means that you should verify the fault has gone away, which will make for an easier situation in the field.

IO Unit 1 Probe 2 Error When Using Analog as Level Device

I/O Unit 1 Probe 2 Error when using Analog (not Probe) as level device

If you have v1.4.0 through to v1.5.2 with analog configured as the level device, it is possible to see I/O Unit 1 Probe 2 Error. This occurs because a bug configures a Multitrode conductive Probe and assigns to the default Digital Inputs 2-11.

It is likely that this bug will only be seen occasionally if the inputs wired to DIN 2-11 are Normally Open (N/O). The fault activates because MultiSmart interprets a closed contact as a sensor being covered with liquid - and if the sensors below are not covered, there is clearly a faulty Probe or faulty wiring.

How do I fix it?

Upgrade to the most current firmware. Contact Multitrode technical support if you need assistance. 

I Can't Upgrade Firmware Using the Compact Flash Card

Try the following steps:

  1. Ensure that the file system on the flash card is FAT or FAT32.  The MultiSmart unit cannot read any other types of file system. You should be able to view this (using a Flash card read/writer) in Windows Explorer under the properties.
  2. Ensure the file is called update.img.
  3. Check MultiSmart can read the compact flash card. This can be done by going into the Settings screen, page 3,  Backup Options screen.  When the compact flash card is in the slot, the bottom right of the screen should say the compact flash card is Present.  Note: this screen does not refresh, so you will need to put the compact flash card in and then go back into this screen.
  4. Check if the MultiSmart can write to the compact flash card.  This can be done by going into the same screen as above and pressing the Backup Current button.  By pressing New, an additional line should appear in the table showing a new file on the flash card.  Press Save to save the file and continue with the prompts.  Press Back when you're done and make sure you are in the Backup Options screen again.  Press Restore Backup and you should see a list of files, one of which should be the file that you saved in the previous step of saving the configuration.  This indicates that the file wrote correctly.

If any of the above has failed, then the flash card is corrupt.  There are two things that can corrupt the flash card:

  1. Ejecting the flash card from a MultiSmart unit WITHOUT PRESSING THE YELLOW "SAVE CF DATA" button and
  2. Writing/formatting to the flash card using a dodgy flash card reader/writer.

The most common is not pressing the yellow button.  By not pressing this button, the flash card has a chance of being ejected while it is writing data.  This will corrupt the flash card.  The problem is the bad file systems that flash cards use.  Almost all digital cameras will have this problem.

In either of these cases, the flash card will need to be reformatted using the FAT/FAT32 file system using a Windows machine.  In fact, this is another step that can be done if all else fails.

I Have a Problem with Configuring DIN1 as Motor Overtemp or Inverted

Problem with configuring DIN1 as Motor Overtemp or Inverted

Problem

Versions prior to v1.4.0 sometimes had issues with configuring DIN1 in certain modes.

Solution

Upgrade to the latest firmware and you will have no problems with DIN1. Alternatively, assign your Motor Overtemp Fault (or Inverted DIN requirement) to another digital input.

How Do I Restore Backup Screen Requests Upgrading to the Latest Firmware

Restore Backup screen asks me to upgrade firmware to the latest version

Reason

Backwards and forwards compatibility are well supported in MultiSmart.However, when a configuration has been created in a newer firmware version, it is possible that some aspects of this configuration will not work - or not work as planned - when loaded into a unit with an earlier version of firmware. As a result, the user interface flags up a warning to the user to give them the option of upgrading firmware first.

Problem in v1.4.0 - v1.4.2

Versions v.1.4.0 - v1.4.2 had a bug with this functionality. When the configuration was older than the firmware, the user interface would also prompt for an upgrade of firmware.This is incorrect. All the user needs to do when asked Do you want to continue is choose Yes on the user interface.

Solution

Upgrade to a version later than v1.4.2 and the warning will only be displayed when appropriate.

            [170 / 320]

            [170] No Pump Running light and the Auto, or Manual, LED is on continuously.

            What’s the status of the pump “Available” light (under the Select button)?

On continuously / Flashing / Off

            [180 / 330 / 400]

            [180] The pump is available, but not running.

First, we have to check the level sensing device. Is the bargraph flashing?

Yes / No

[1000 / 190]

             

            [190] The pump is available, but not running, and the level sensing is working.

This probably means that the pump is outside of the required levels to pump. We will need to check some settings to verify the Pump Controller programming.

Check EDS 1. (See the interactive pump controller demo if you have not used the configurable parameters – called EDS’s – before). As a quick guide, EDS 1 is very simple.

Press the key combination marked in GRAY as “Switches”. This gets you into the EDS selection menu. EDS 1 is the first EDS selected. The bottom left LEDS, marked “Switch On/Peak Levels”, indicates the status.

If the bottom left LED is OFF, it is a discharge application which is the default; if the bottom left LED is ON, it is a charge application. Exit by pressing ALARM RESET.

Is the application a discharge (empty) or a charge (fill) application?

            [200 / 260]

            [200] The pump is available in a discharge application.

Check the set points by pressing the key combination marked “Set Levels”. Then press “Pump 1” to check the set points for the Duty (Lead) pump, “Pump 2” to check the Standby (Lag) pump, etc.

The bargraph will now be flashing with the high and low set points for that pump. Make a note of the setpoints and press the EXIT key. What is the current level in the well?

Higher than the high set point / Between high and low set point / Below/span>  or at the minimum set point.

            [210 / 250 / 240]

            [210] The pump is above the high set point in a discharge application.

Are you checking the Standby (Lag) pump when the Duty (Lead) pump is already running?

Yes / No

[220 / 230]

            [220] The pump is above the high set point in a discharge application and another pump is running.

Check that EDS 15 – Maximum pumps to run at one time is not limiting you to one pump, and that you have already checked the Standby (Lag) set points. If the current level is above the Standby (Lag) set points and is not ON, note the number for this paragraph and contact Multitrode support.

            [230] The pump is above the high set point in a discharge application and no other pumps are running.

Are you sure that the “Available” light is ON, but not flashing? And that EDS 1 is OFF? And no other pumps are ON? If so, please note the number for this paragraph and contact Multitrode support.

             

            [240] The pump is below the minimum set point in a discharge application.

The pumps should be OFF. The well is empty. The pump controller is acting exactly as programmed.

Return to pump controller main menu

             

            [250] The pump is between the two set points in a discharge application.

The pump controller in its most basic form is providing a latching circuit. The level rises to the high set point and the pump(s) switches ON. This draws down the level until the low set point is reached, at which point the pump(s) stops. Then the level will rise again due to inflow. If the level in the well is between the two set points, there is nothing wrong with the pump being OFF.

            Return to pump controller main menu

            [260] The pump is available in a charge application.

Check the set points by pressing the key combination marked “Set Levels”. Then press “Pump 1” to check the set points for the Duty (Lead) pump, “Pump 2” to check the Standby (Lag) pump, etc.  The bargraph will now be flashing with the high and low set points. Make a note of the set points and press the EXIT key.

What is the current level in the well?

Below the low set point / Between high and low set point / Above or at the maximum set point.

            [270 / 300 / 310]

            [270] The pump is below the low set point in a charge application.

Are you checking the Standby (Lag) pump when the Duty (Lead) pump is already running?

Yes / No

[280 / 290]

             

[280] The pump is below the low set point in a charge application with other pumps running.

Check that EDS 15, maximum pumps to run at one time, is not limiting you to one pump, and that you have checked the Standby (Lag) set points. If the current level is below the Standby set point and is not ON, then please contact Multitrode support.

            [290] The pump is below the low set point in a charge application with no other pumps running.

Are you sure that the “Available” light is ON, but not flashing? And that EDS 1 is ON? And no other pumps are ON? If so, please contact Multitrode support, quoting the number on this section.

                        

            [300] The pump is between the two set points in a charge application.

The pump controller in its most basic form is providing a latching circuit. The level falls to the low set point and the pump(s) switches on. This fills the reservoir until the high set point is reached, at which point the pump(s) stops. Then the level will fall again due to outflow. If the level in the reservoir is between the two set points, there is nothing wrong with the pump being off.

Return to pump controller main menu

            [310] The pump is above the high set point in a charge application.

The pumps should be OFF. The reservoir is full. The pump controller is acting exactly as programmed.

Return to pump controller main menu

                        

            [320] The Pump Auto light is flashing - the maximum station starts or max pump starts has been exceeded.

EDS 17 and 18 control the “Maximum starts per hour” to improve station efficiency. EDS 17 sets the desired station starts per hour. For example, with EDS 17 set to 10, if the Duty pump is required to start within 6 minutes (10 starts per hour), the Pump Controller will flash the “available” light and increase the range in the well dynamically. It keeps doing this until the value set in EDS 18 is reached.

EDS 19-21 control maximum starts for each pump. See the manual for more details.

            [340] The Pump Available light is flashing slowly – Power Fail input present.

            The pump “Available” light flashes slowly when the Power Fail (PF) /Hold Out input is closed and the pump is not available. Is the input short circuit?

Yes / No

            [350 / 360]

            [350] The Power Fail input is preventing the pump from being available.

The pump controller is operating correctly.

Return to pump controller main menu

            

            [360] The Power Fail input is faulty.

If you are convinced that the PF input is not short-circuit, then the Pump Controller is faulty. Note the number at the start of this heading and click here.

            [370] The Pump Available light is flashing quickly – LAN or MonitorPro fault.

            This indicates that either the LAN is faulty between a MonitorPro and Pump Controller. The fault lights under the “Available” light will also be flashing. Is there a MonitorPro connected to the Pump Controller?

Yes / No

            [380 / 390]

                        [380] LAN or MonitorPro Fault and MonitorPro connected.

Check EDS 44. It will be set to 2. This is a configurable parameter on the Pump Controller which locks out the pumps when the comms fails between it and the MonitorPro. It is a failsafe mode.

The pump controller is doing what has been requested. If you want to make the pumps work regardless, change EDS 44 to 1. This enables comms, but takes out the failsafe.

            

            [390] LAN or MonitorPro Fault, but no MonitorPro connected.

Check EDS 44. It will be set to 2. This is a configurable parameter on the Pump Controller which locks out the pumps when the comms fails between it and the MonitorPro. It is a failsafe mode. As there is no MonitorPro, you need to set EDS 44 back to 1 (default) or OFF. The pumps will now become available again.

Return to pump controller main menu

             

            [400] The pump is not available.

There can be many reasons why the pump controller has made the pump unavailable. Are any fault lights flashing below the “SELECT” button?

Yes / No

            [410 / 420]

            [410] The pump is not available and fault lights are flashing.

There is a fault. See the fault light guide on the website.

             

            [420] The pump is not available. Everything was checked except grouping of pumps.

If pumps have been put into more than one group, the current pump may not be in a group. If you have an MT3PC with 2 groups setup, or more than one MT2/3PC connected together for a 4-9 pump application, you will need to carefully check that the pump is in a group.

            [660] The keypad is faulty.

Note the number at the start of the heading and click here.

             

            [800] There’s no level in the well according to the pump controller.

First, we need to check the display.

Press Select Two and Reset Two simultaneously (simulation mode). The Select One and Reset One lights should be flashing alternately (as in the picture below).

Press Select One (increase simulated level). There should be some level displayed on the bargraph. Then press “Duty Select” (exit).

Did the lights come on as described?

Yes / No

[830 / 810]

            [810] No lights came on, even in simulation mode.

Is the faceplate connected to the main unit?

Yes / No

[815 / 820]

[815] No lights came on and the faceplate is connected.

Please cycle the power. Whenever the keypad has been disconnected, the unit should be restarted. Is the display responding now when you try the Level Simulation test?

Yes and there is level on the bargraph/ Yes, but no level/ No

[Main menu / 830 / 660]

            [820] No lights are on, because the face plate is disconnected.

Reconnect the face plate and cycle power to the unit. Is the display responding now when you try the Level Simulation test?

Yes and there is level on the bargraph/ Yes, but no level/ No

[Main menu / 830 / 660]

            [830] The bargraph is working, but no level is displayed.

Is the main level sensing device a Probe or a 4-20mA transducer (e.g. pressure transducer or ultrasonic device)?

Probe / 4-20mA

[840 / 940]

            [840] No level is being displayed with a probe input.

Check the level in the well or reservoir. It is very likely that the level is below the level of the bottom probe sensor (i.e. the well is empty).

If this is difficult to check, or the liquid level is above the lowest sensor, check the input of the Pump Controller by disconnecting the Probe and shorting input P1 to ground.The bottom LED of the bargraph should light up. If it does, the Pump Controller is working correctly.Is the pump controller bargraph working with a short circuit to ground?

Yes / No[850 / 900]

            [850] No level display, but the pump controller is working.

The Probe relies on an earth return being present, usually via the pumps or other metal in the well. If there is not a natural earth return, you need to install an earth return rod approximately 300mm from the Probe.

Is there an earth return?

Yes / No

[860 / 890]

            [860] No level display and the earth return has been checked.

Take away the short circuit and reconnect the Probe. The Pump Controller has a sensitivity setting. On the face plate, you will see “Sensitivity” in GRAY showing a key combination to be pressed. Press both keys together and a single segment will light up on the bargraph. Read across to the Sensitivity value. Adjust it by using the Select One and Reset One buttons.

Change the value to 1.5k Ohms. Does the bargraph register the level in the well now?

Yes / No

[870 / 880]

            [870] Sensitivity adjustment needed.

The default Pump Controller setting is 20k Ohms. This is suitable for most liquids, but can be incorrect for water with high salt concentrations or other chemicals. Try adjusting the sensitivity up and down to find the best point for your installation.

            [880] Possible faulty Probe.

Please note the number at the start of the heading and click here.

            [890] No earth return.

If there is not a natural earth return, you need to install an earth return rod approximately 300mm from the Probe.

            [900] Probe inputs to the Pump Controller are not working.

It looks as though the Pump Controller may be faulty. Note the number at the start of the heading and click here.

                                    [940] No level is being displayed with a 4-20mA input.

If the 4-20mA device goes below 3.5mA, the whole bargraph will flash. If the whole bargraph is not flashing, it means that the device has not totally failed. Check the actual level in the well or reservoir. The device may be reading the correct  calibrated reading. Otherwise, you may have a faulty device.

It is possible, but very unlikely, that the Pump Controller input has a faulty calibration. Check by feeding in 12mA.  The display should read 50%.

If it is a faulty Multitrode device, please note the number at the start of the heading and click here.

            [1000] The bargraph is flashing.

The Pump Controller flashes the bargraph when it detects level device faults, or conflicts between primary and backup level devices.

[1050] [1010]

            [1010] One or more segments of the bargraph is flashing.

If some segments are flashing, but the highest segment lit is solid, it means that some Probe inputs are faulty, or not what the Pump Controller was expecting.

EDS 5 is set to OFF, which means that a Probe input is expected. If you are using single sensor Probes or ball floats instead of a 10-sensor Probe, EDS 7 needs to be set to ON. This tells the Pump Controller that not all sensor inputs need to be covered sequentially. That is, liquid rising in a well should first cover sensor 1, then sensor 2 and so on. If, for example, sensor 3 is covered first, then there is clearly a contact problem to the Probe.

            [1050] The whole bargraph is flashing.

The primary level sensing device should be a 4-20mA signal. The bargraph flashes the input current is outside the range 4-20mA. Check your level sensing device. If you have a current source, you can feed in a 4-20mA signal to the Pump Controller to determine whether the level device or Pump Controller is faulty.

[1060] The bargraph is flashing with one segment solid.

The bargraph flashes in this way when there is conflict between level sensing devices or an analog input has failed when a Probe is the backup device. The solid segment is the level the Probe is reading. The display is flashing to show you that the analog input is outside 4-20mA.

To determine if the Pump Controller or 4-20mA device is faulty, check the device with a current meter.

Why are there no lights on the display?

            [1200] There are no lights are on the Pump Controller face plate at all.

Press Select Two and Reset Two simultaneously (simulation mode). The Select One and Reset One lights should be flashing alternately (as in the picture below). Press Select One (increase simulated level). There should be some level displayed on the bargraph. Then press “Duty Select” (exit).

Did the lights come on as described?

Yes / No

[1210 / 1220]

            [1210] The lights come on in simulation mode.

This means the display and keypad is working correctly. All pumps may be decommissioned (check EDS 35-37) and there may be no level in the well.

            [1220] No lights come on in simulation mode.

Is the face plate connected to the main unit?

Yes / No

[1230 / 1240]

                        [1230] No lights came on and the face plate connected.

Please cycle the power. Whenever the keypad has been disconnected, the unit should be restarted. Is the display responding now when you try the Level Simulation test?
