Unusual speed variation OF 2200

[naushad]

[unsure]
Hello,
This is my first post- brief intro- My name is NAUSHAD BUROKUR I am from Mauritius Island, 41 years old, married and two children, Customs Officer as profession but woodworking as passion, came first in my country in woodworking studies during school days- could not pursue further studies in that field and a lack of this tradesmen-ship demand forced me to opt for another profession for a living.

I am in a position now to use my spare time to fulfill my dream of becoming a professional woodworker and by GOD's willing  may be to put my country on the map by presenting some of our talents on an international basis at the AWFS FAIR who knows..........
Bought all my Festool products from UK and some Incra Jigs from US-
Actually working on a project incorporation my CMS ROUTER and my INCRA LS SYSTEM on a movable table will post some photos upon completion.

Problem:
I have noticed while operating my OF 2200  an unusual variation of speed- the router will runs normally on a preset speed at initial but suddenly variates to a higher speed after 2 to 3 seconds of operation and returns back to its initial preset speed this is repeated constantly in 2- 3 min a lap interval. Could anyone assist this new comer please.
Thanks
Naushad

Hi and welcome sounds like the speed sensor in the electronics is shot, I had something similar on my CS 70.

This may sound silly, but simply exercise the speed control dial by rotating it back and forth quite a few times. If the problem goes away, then it was just dirt on the variable resistor used for the variable speed control.

If that doesn't affect anything, then it is probably the speed sensor. That is more complex and would require service.

Hi and  [welcome]

Is your local power stable and are you certain the circuit you're running the router on supports the current draw? ... Have you tried running the router from a different supply point?

Are you using an extension cord? ... Is it powered via a DC?

(just trying to eliminate variables)

Also, sometimes electric motors require a little "run in" time. How many hours has the router been operational?

If you exercise the speed dial as suggested, your power is adequate and stable and you've given it some run in time - you'll need to get service involved.

Thanks for all the tips will try and revert back for feedback.
By the way I've tried to connect the router to another outlet but with the same result.
Will have to check for any variation in the electric supply itself I think a volt meter will ideal to detect any variation?
I try to avoid using extension cord as possible and the router is always connected through my CTL- DUST EXTRACTOR

Hi and welcome

Without getting too technical, a few pointers.

I assume you got the 240V versions of your tools, if not my numbers wont be right but...

If you're running the router thru your CTL you have to consider the load on your circuit/fuse will be 2200W + 1200W = 3400W
Your circuit needs to be able to take that load, so a 10amp fuse would probably trip. An easy way to work it out is to divide the load (Watts) by (volt) that will give you a number of 14,2 (Amps) in your case.
Don't know anything about the electrics in your country but in my case a 16 Amp fuse would be the least for the circuit. You also have to consider weather you got more stuff connected to the same circuit like lights, fans or other tools running at the same time.
The easiest way to rule parts of this out is to try running the router thru some wood (not just idle) but without the CTL.
Another thing is to check weather you got 240V in your outlet (use your voltmeter), many times the power can differ a lot, if that's the case you have to recalculate my example above.
One other thing to mention even if you're not using an extension lead is that if you where, the extension lead HAS to be rolled out off the wheel. A rolled up extension cord can most of the time only take half the load without risking the cord to melt or burn.

Hello,
Seem to have found the problem( SILLY MISTAKE), the CTL 55E power outlet have a max capacity of 1800 watt while the OF has a 2200 Watt capacity, thus connecting the OF 2200 with the CTL will overload the circuit.....I think???.
Well I have tried to connect them separately and it works no variation but the only problem now is that I do not have an automatic dust suction when working with the OF.
Can the power outlet on the CTL 55E be upgraded?
I think Festool no longer have his model//

 

[fdengel]

I think the outlet max capacity thing is due to certification issues more than actual limits on what the CT can handle - but I could be mistaken...

Regardless, there are external boxes that you can get to hook things up to make this work.

A quick search turned up this one: http://www.amazon.com/M-Bright-iVac-Automated-Vacuum-Switch/dp/B0035YGLZG

I suspect you should be able to find something similar that would work for you (the link above is an example which obviously won't match your outlets).

Would like to share what Festool said about this problem, here is a copy of there mail: 

Hi
  I am the Technical Trainer for the U.K and your enquiry has been passed on to me.
From the information that you have provided it appears to be one of three possible issues.
·        Input supply
For smooth continuous running the input supply needs to be constant with no variation in power supply. If this is not provided then the electronics can be ‘confused’ as they need a smooth continuous supply of power.
·        Cable
Check the condition of all the cables and connections for any damage.
·        Electronics
It may be that the electronics are faulty. If this is the case then a variation in speed can be an indicator of this.

I hope that this is of some help.

Hello,
Have made some test case with the CTL cable rolled up partly and speed variation occurs and with the cable completely unrolled no variation at all??????
What is the rational behind this??
