Feedback Controller Support

I have just been told that Richard, one of our group's founder members has suffered from a serious motoring accident in the Highlands of Scotland and he is now permanently paralyzed.  He asked his wife to send his resignation to me as he knows deep down he will not be able to do any more work for our group.

The group's constitution says that while two founder members are active members of the group we can't close the group down.  I am the only surviving founder member of our group and with Richard's accident, it places a great burden on my shoulders.  I relied on Richard's advice on Group matters and now I am sad to say I feel I am on my own in the middle of what seems like a massive crossroads with no signposts to help me choose the right direction.

I will seek legal advice as it seems I am the only one who can make a decision as for the future of the group.  Whatever I decide to do I will announce it on this website

I am in the middle of several controller repairs but I need a little time to pull myself together and go to see Richard.  My apologies if I am working on any reader's controllers for the accident will be the cause any delays in repairing any reader's controllers. 

I will get back to the repairs after I go to visit Richard in Scotland and return home.





Before we heard about Richard resigning we decided to put the production of back EMF feedback controllers on hold for the foreseeable future and concentrate on providing a repair, upgrade and support service for users of back EMF Feedback controllers.




Why  have  we changed the name of our
previously made Feedback Controllers?


The answer is simple. The controllers we previously called feedback controllers are in fact back EMF Feedback Controllers.  A term that some DCC users may be familiar with. The change in name is to distinguish them from a new controller we are developing which are best described as voltage feedback controllers. 

These new controllers that are under development samples the controller output voltage and not the back EMF generated by the motor.  The regulator circuitry then compensates for any drop in voltage that was not determined by the controls. Modern highl efficient can and coreless motors do not like the pulsed output of the standard KPC feedback controller and these motors will run better on a pure DC output that is not pulsed. 



Controller Recycling Service

To keep in line with current UK recycling trends we are introducing a new service to owners of KPC equipment, regardless if we manufactured it or not.  Owners of electronic controlled model railway power units, hand held controllers and other items such as power supplies and station stop units who wish to dispose of unwanted equipment need not fill their refuse bins and bags with these items.  We are offering a free recycling service where KPC equipment will be dismantled, and sorted out into groups of unusable items and items that can be used once more in repairing faulty controllers and other units.  Some items will be refurbished and sold on.  The profits going to pay for our web site and any surplus going to a local Cumbrian charity.





Storm Desmond Hits KPC Support Workshops

In the later part of 2015 while many parts of Cumbria were again under flood waters when KPC Support, situated very near to the northern banks of the swollen River Derwent missed the floods but were hit by a freak storm of near hurricane proportions.  Our new workshops, a sturdy timber build structure was torn apart like a Superquick model building.  The workshop was a tongue and groove. shiplap garden shed donated to us by a local businessman.  It was errected on a plastic subframe and had been in use for a couple of years.  Storm Desmond ripped off the roof and despatched a dozen or so yards away in an empty car park.  The storm ripped the side panels apart and scattered them around Tom's garden. 

Alerted by an intruder alarm screaming its head off Tom began to gather up the contents of the workshop and move them into his home.  We lost to the torrential rain a Dell laptop computer that contained the info about our customers we were providing support for.  It was connected to a further pair of Dell computers by a wi-fi network but it was the one we used for our day to day email work. 

We were very lucky to rescue all the feedback controllers we were working on for customers and with the exception of one unit, they appear to not have been damaged by the storm.  The problem one was one of our own stock controllers. It was a 1 amp version we were converting to a 3 amp version to provide a replacement for a burnt out 0 gauge controller belonging to a customer.   We are stuck in our tracks until we can source a suitable donor controller we can upgrade. 

Saying that we are definitely stuck in our tracks for providing physical support for our customers until we move back into our workshop.  We hoped to use the living room as our workshop but it didn't work out like we hoped.  Progress is very slow in rebuilding our workshops as the foundations for our workshop were almost washed away, not by floods but the sheer amount of rain over the last three months.  The rain we have endured since November had prevented us constructing a new base for our workshop.  The ground is still waterlogged after three months and four of the eight paving slabs we used on top of the hard core to support the sub frame base have sunk into the ground with the weight of the new base and the re-erected workshop.  We had to strip down the side panels and pack the timber base to make it level but these last few days after we once again assembled the workshop we discovered it is again sinking slightly.  The group took the decision to continue working on the building and at the moment we are half way through wiring out the workshop.  We have fitted two new fluorescent light fittings and these have been tested. Now we can work on the workshop outfitting after dusk.  Next will be the fitting of more locks, the security alarm, an intercom and landline phone.  Once we are happy with the electrics we will build new benches and storage cupboards.

Last years storm feels like a minor issue when we think of how we were flooded out of our workshops and offices in Carlisle back in 2012.  We hope to get back to normal soon and when we do continue work in developing our new none feedback controller that is designed for the most recent N Gauge models from Dapol and also for the slightly larger precision motors like the latest coreless and can motors.




In 2011AD, Tom Jenkins the driving force behind the WMR-Group was advised to retire because of ill health and a leg injury.  He never saw the business move from Workington to a new location in Carlisle. We moved to an office near to the River Eden in Carlisle and in the basement and part of the ground floor we set up our stores, manufacturing workshops and main offices.  Tom was fortunate not to experience the disaster that was to follow a few months later.  We were unaware that Carlisle had a history of flooding with flood events recorded as far back as the 1700s. In recent years there have been significant floods in 1963, 1968, 1979, 1980, 1984, and recently in 2005. 

Our landlord never told us that in 2005 he was advised to make alterations to his property so that it would be covered by insurance in the event of another flood.  He ignored the advice and as a result The flood section of our business insurance policy was void.  Disaster struck Carlisle again in 2012 for the weekend of June 24th 2012 there was another flood but thankfully not as bad as it was in 2005. Bad enough for it terminated our manufacturing facility in Denton Holme, Carlisle.

After winding down our manufacturing subsidiary in Carlisle, paying all our creditors we find that there are not enough funds to invest in opening a new manufacturing facility.  We were let down by our insurers when they pointed out we were not covered against flooding.  This arose because our landlord had not taken precautions to prevent flooding to his premises.   A point he failed to tell our group when he granted us a "Caretaker Tenancy" with a token rent.  Attempts to recover our losses from the landlord has failed miserably because he passed away while visiting his family in Spain.  He died from a massive heart attack following a stroke.  Apparently, according to gossip in Carlisle he was fleeing from bailiffs who were trying to serve a bankruptcy summons.  That scuppered any chance of us getting compensation for our loss.

After a long period of inactivity following the flooding of our manufacturing facility in Carlisle we have decided to operate a part time support section to repair only the Feedback controllers supplied by Kent Panel Controls or the recently reformed New Kent Panel Controls. In order not to disappoint past customers we decided to provide a support section that dealt with issues only related to the range of KPC Feedback controllers.

We are pleased to announce support is available once again under the direction of Tom Jenkins, who many of you will remember, retired due to illness followed by an accident prior to our move to Carlisle.  We have managed to talk Tom to head this NEW support section.  He will be perform repairs to any version of KPC Feedback controller be it ones made in Kent; Nairn - Scotland or Cumbria. Naturally any controller manufactured in Cumbria is covered under our ten year guarantee and there will not be any repair charges within the first ten years.  At the moment we are unable to build controllers of any kind but that position could change sometime in the future.
