just got a stream box battery and pump this morning connected everything up set calibaration to 30 .  but it wont work pump is trying but thats it  ,

de code stands for dead end has been detected ..       mike

[dazmond]

what happened to the extend2wash pumpbox you bought the other week mike?

[Mike #1]

will let you know in due course .  you got mail dazmond

[andyM]

Have you primed the pump?
If the pumpbox is above the tank it may be that there is not enough suction.

[Mike #1]

not connected into tank yet , just dropped hose in lid .  i have sucked on hose to draw water through hose into pump and then connected to inlet

Raise the cal to higher than 30. Until it pumps and only registers dead end when you shut the hose off. You get to cal by pressing the far left a right buttons together.

DE = Dead End.

You need to calibrate your variflow:

Adjustment Procedure:

With the Varistream VSD6 switched on - press up and down arrows simultaneously for three seconds to display the pressure setting.

Release the up and down arrows for 1-2 seconds - then press up and down arrows simulateously for three seconds and the digit will flash.

Use the up and down arrows to select the figure you require (you will need to increase the number).  If the pump is shutting off at too low a pressure, select a higher number, if the pump is not switching off - select a lower number.  It is recommended that you change by one increment at a time to avoid large swings in shut off pressure.

Once the desired number is displayed switch of the varistream.

When you switch the varistream on again, it will have accepted your new setting.

(The above was taken from the instructions that came from mine; the stuff in brackets was my addition.)

Hope this 'elps.

i have raised it to 99  and i am just getting a stop / start on pump,   for 2 seconds it starts then stops , first time with digital controller dont want to mess onto much incase i damage pump and controller  

[Mike #1]

its the variflo v9 ,  thanks for your advice so far lads .  MIKE

[Mike #1]

still no luck totally baffled .  MIKE

[Tom White]

I'd suggest standing by your van on Monday morning, phone the supplier, and ask them to take you through the calibration process.

I had to 'fanny about' with mine for a while before I got it right; it's well worth the hassle.  I have a lovely flow of water, and when I cut the flow, a second or two later, my pump cuts out.  It runs just how it should.

But it did take some fannying about, as I say. 

I'm pretty sure the supplier will be to talk you through the process.

thanks a lot lads for all your input i had 'nt been pressing the buttons correctly in order to set the cal correctly got it now just need to sort out the odd little leak ,   MIKE

Hi Mike

Have you been able to set the auto calibration OK now if not give me a shout and we will go through the set up.

Ian

[Mike #1]

cant seem to get auto cal on ,  had a really good flow rate today had the cal set at 55 and the flow  at 44 and it was all good                                                                                                                                                           ,  then as tank was getting towards empty it had about 70 ltrs left in a 400 ltr tank and flow rate dropped off to almost a trickle   then picked up and dropped off again even though i upped the flow rate ,

so i am hoping flow rate will be ok once i fill tank and check it over .

Thanks Ian ,  what is the benefit of auto cal .

Also pump was not cutting out when the water was low but worked a treat before

[Ian Sheppard]

Mike

The main benefit of the auto calibration feature is that once set you should not have to adjust the calibration. The DE will come up when the water flow is stopped and restart once the water is flowing again. Getting the calibration right is the key.

It is best to run auto call with your longest pole as the control will automatically adjust to a shorter pole so once the control is on and you have a water flow follow the steps below to set up auto cal

1. press the up button until the display shows 30
2. press and hold both up and enter to go into the auto cal mode (display will show Cal)
3. press down to select auto cal (display will show AUT)
4. press enter to start
The display will show AUT while the function is running this is normal once the control has found the optimum setting it will display a figure normally somewhere between 30 and 60
5. Press enter to save the setting (display shows SET)

Once this is done the control should automatically adjust to any shorter poles.

As for the flow stopping when your water level is down to 70 litres. Could it be an air block somewhere? may sound daft but is the pipe in the bottom of the tank? has the water level dropped below the feed pipe?

You may find that once the auto cal is set up the issue will solve its self. If this does not work let me know and we can try something else.

Cheers

Ian

[Mike #1]

Thanks Ian outlet for tank is at the bottom as normal .   Will try auto cal a bit later i assume the pole will need to be extended then collapsed in order to ensure everything is working correctly .

Also as i understand it when de    is displayed the pump is still trying to work and has not shut down completely as you can hear the pump  , when it shuts down i get PS showing on controller which indicates  pump stopped . and it does shut down completely if one of my connections works loose ever so slightly i will get de showing


MY mistake may have been not getting everything set up properly spoke to philip at cleaning spot and he said i need to have the cal and the water flow set at the same setting

[SherwoodCleaningSe]

dE means dead end, the controller has detected that the pump is struggling so therefor must have a dead end on a hose, so it stops the pump but tests it every 3 seconds to determine if there is still a dead end.

PS. Means pressure switch, if set up correctly the controller will keep testing the pump when it has detected a dead end, because the pump pulses a little this builds up pressure in the hose and back pressure to the pump, it then activates a pressure switch on the pump.  The controller will not test the pump at all now until the pressure is released from the hose and the pressure switch deactivates itself.

As for cal and flo settings, these do not have to be the same. My cal is 25 and my flo 70 and all works fine.

Simon.

[Ian Sheppard]

Thanks for coming in there Simon
 you are right that the Calibration and water flow rate do not have to be the same, as a general rule of thumb we would expect to see the 2 rates somewhere between 28 to 55, However each system is different and you will find the flow rates and calibration will differ system to system.

The key is getting the control set to your own system and adjusting the flow rate to suit. Mike you can extend the pole when setting up the auto Calibration as it will be more accurate.

I tend to think of DE as water flow off. The control will stop the pump when it detects DE (no water flow) Simon again spot on the control then retests approx every 3 seconds to see if the DE is still there the control send a pulse to the pump hence you will hear the pump briefly 1/2 a second usually less.

This happens when the controller detects the water flow has stopped.
1) Check there are no air bubbles in the system. Run the pump to bleed air from the system
2) The hose has become disconnected or twisted
3) The water tank is empty
4) The auto calibration needs to be set
Adjust your flow setting carefully. Repeated false dead end detection indicates that the cal value should be increased (less sensitive)

Prolonged use of the control with high calibration may lead to damage to the control or system. Do not set the Cal too high. Setting it higher than necessary places extra strain on both the pump and controller in DE situation.


PS = Pressure Switch
The controller is telling you the pumps pressure switch has been operated due to a high build up of pressure in your system.
The controller is set to work with a pump up to 5.2 litres per minute and 100PSI although it will and can work at higher ranges.
Common causes for the pressure switch operating could be
- A restriction in the system
- Blocked or small water jets (recommended 2mm)
- Grit or dirt trapped in the system
- Air blockage
- Prolonged shut off of the water flow
In very rare cases if you have disconnected the pump pressure switch and are relying only on the controller to detect Dead End when the water flow has stopped, the following can occur 
- The controller will re-test the DE every few seconds
- the Pump appears to Cycle (start then stop)
- The system pressure may build up slightly
- There is a risk of a failure of your hose connections
- The Controller and pump are still drawing current
- Risk of damage to the pump and controller

The Control is designed to work with the pump pressure switch to provide additional protection to your system. We always recommend that the controller is operated with the pump pressure switch as it will give an additional back up and in the above example will avoid damage to your system as the pressure switch will cut out before dangerous high pressure builds
This is one of the differences between our control and others available on the market.

A controller with dead end detection properly calibrated, the pump will be stopped a long time before this high pressure and high pump load. This means that because the pump is turned off earlier you are saving battery energy and hence increasing both the battery life but also the amount of time you can work on a battery charge

Soz for the long winded explanations

Let me know how you get on Mike. Where abouts are you?

[Mike #1]

Thanks to you  both lads i will turn my cal down,  I ahave had cal and flow both at 55 but will try on the same settings as you simon ,

Although i am using 100 mtrs of 6mm microbore and have 1mm pencil jets fitted to brush and have had really good flow maybe a little to much at times but after a 7hr shift still have some water left,   but do need to adjust a bit .

Ian i am in the north east 9 miles outside Durham city , I prefer the long wind explanations mate it means i virtually all my answers in one post.   Thanks again MIKE

[Ian Sheppard]

Your Welcome Mike

let me know how it settles down.

Ian
