Maha brake tester fault

[browny]

I have new maha brake testers installed,
We are having a problem when used in automatic mode.
What hapens, after a lock the system dosent seem to see TARGET BRAKE FORCE REACHED.

The guys at maha have been great and trying there best to solve this problem but cant seem to find the fault. They tell me they have never seen this before.
Has anyone else had a problem like this with maha brake testers ?

We have a Boston digital never given an ounce of a problem. Yours sounds like maybe a software issue???

I went with maha as i was told they were the best but, iv now been open just over 1 year and we have had this same problem from the start.

Maha have told me im the only one in the uk with this fault and it looks like there is a power problem into my building.
But wr have now had this checked by 2 electricians and northern power grid who all say my power is fine.
Allso everything els in my building works fine with now issues at all.

Its now becoming a bit of a pain as i have invested 30k on equipment thats not working properly.
This only happens on automatic mode.

I used MAHA for a few years, and I reckon it is good equipment but typical German a bit over complicated with some things. All I can suggest is that you get the engineer back to sort it out, it could have been a poor installation

[browny]

What im looking for, is to ser if anyone else is using this equipment in automatic.
Just to see if its only me with this fault.
Everyone i have spoken to runs theres on manual.

We have a german set up at our place and I can't be ars... bothered to find out the make but ours has a large sticker on it saying MOT testing must not be carried out in auto mode !!!

ps it is about 200 years old though

"TARGET BRAKE FORCE NOT REACHED"

What actually happens when the brake test is complete and the target brake force is not reached!!

[browny]

If the system Dosent see the target brake force it wont allow the test to go on.
This only happens now and again.

When I used it I was doing about 10 test a day, the brake tester was very nearly always in full auto, never had the issue that you are on about though.

Sounds like a weighing issue to me.

Your brake tester is looking for a target only after one of the axles under test has already taken both wheels to lockout

I have found with my brake tester which is fully automatic but not a MAGA that if the both wheels lock initially on the first phase but there is a very large imbalance then it can be impossible to reach the target if the lower effort brake locks when checking for bind, ovality etc on the next phase.

you can test in manual mode when this happens , I don't think you have a fault

you could try this but not as part of the test if it happens again, if you cannot reach target, start brake test over again ( both wheels running together)  but only take the lower effort brake to lockout before releasing pedal, and then see if it reaches target on the next phase .

I think we had a special notice about lower brake efforts locking out, if that occurs we are supposed to ignore the lower effort lockout as the MTS system has been setup to also ignore it.

I think there is a software problem im having as it works as ot should for some time then goes wrong now and again.
What im looking for is someone with the same roller as me working them on automatic mode, and see how they are getting on .

I used MAHA rollers for a couple of years on auto, but had no problems with it

Thats what people are telling me aswel
Maha seem to think the problem is my power coming into my building.

Maha have been great and are trying to solve the problem but cant seem to get to the bottom of it.

This is why im asking around if anyone else has ever had this problem.

Two of our centres have Maha equipment, I test on one. It stays in automatic mode and has never shown the issue you describe in 8 years.
