stress control not working - tw 24/150ph

[cimh]

Hello

 

Recently acquired a 2002 TW 24/150PH. sn 20207004

 

Unfortunately the stress control has been bypassed and when we disconnect the bypass the rollers dont rotate.

 

The wiring connections look clean and the sensor is very close to the gear cog. The rev counter shows the engine is running > 3300rpm so I assume its going fast enough.

 

The stress electronics are in a small aluminium box in front of the hydraulic valve/switch. The box has a small green light on the top which doesnt light at any speed. the electronics inside the box look clean and dry.

 

My questions are - does this sound like the original stress unit?

What is the light supposed to do when its working properly?

Any ideas on how I trouble shoot this one? for example how do i decide if its the sensor, the stress unit or something else?

 

Any suggestions gratefully received.

Hi Cimh

 

The aluminium/grey box you have found is indeed the original No Stress unit and the green lamp should be illuminated when the ignition is switched on, it indicates power is getting to the unit.

This means either you have a power in issue or the switch itself has failed.

 

RPM for your machine at full speed should be 3400, running at 3300 will not let the rollers work, but as you have no green lamp illuminated the problem is probably elsewhere.

 

Your best route for advise will be to call Timberwolf's Technical help desk on 01449 765820, they should be able to assist you.

Many thank for you help

 

The machine is indeed running at 3400 as you say that should be OK. I'll check first to see if I can get 12v going into the unit.

 

If I am then I'll ring tech support.

 

Thank you
