SunSport 2021 Turning Off Early

[imported_Suntanz]

I have SS 2021 that is turning of in the middle of sessions. It does it quite unpredicably. Sometimes it runs fine, others it will end the session at random times. When it turns off the "on bed" timer will be at zero and the canopy will raise just like a normal end of session. However the tmax timer will still have time on it. This just started happening recently -- worked fine for ever.

I have checked the exhaust fans and limit switches - all look good. Any idea on where to start trouble shooting would be appreciated.

loose wiring and/or plug on the back of the control circuit board or one of the wires connected to the board

[imported_Suntanz]

Thanks for the fast reply. I found a connection that appeared kind of loose. Fixed it and now time will tell :-).


Thank you.

I know this thread is really old, but we are having the same problem with our ss 2021. We purchased this salon about a year ago, and have had nothing but problems with ours. We replaced the control board about 500 hrs ago and it still shuts off early every now and then.
Any other good ideas on what to look for?

[sparky]

D.tails..... D.tails.........

D.scribe the situation when it happens.

within first minute or less ?

towards middle or end of session ?

what does the display board show/do ?

does t-max continue to count down ?

does the canopy open or stay closed ?

Input! more input! Johnny Five needs Input!

sometimes after 2 mins the half bell dings, sometimes 4 min into it.
sometimes after 19 mins or so, it will shut down like session is over she talks about next apt. but the fst timer still reads 5 min or so.
could it be the emerg. button malfunctioning.

[tbtan]

does this machine by chance have a way to produce error codes on display to help find out why it is shutting down. Also it seems to act up more when you mess with the flip time, for the people who only want 10 min on each side. ( thats when it seems to ding at an odd ball time) hope this helps and thank you.

keep thinking of stuff with this bed, there is a ballast or tranformer that hums( i was told nothing to worry about- loose coils vibrating) and there for a while it was going thru the 30uF caps in a matter of hours. When we got the place they had it hooked up to run off of 208V and where sending 240V to the bed, switch all transformers to 240V, worked for a while and now it is acting up again.

Things that can cause it to shut off.

The switches on the trays that fold down so you can acess your lamps.Tape them shut or jump them out.The slightest opening of these switches will turn off your bed.

The air flow switches in the base of the bed.If these shut for a microsecond ,your bed will shut off.

A lamp that is showing signs of arcing or is making a buzzing sound can cause your bed to shut off.So look at your lamps and listen to them.If you notice buzzing ,change that lamp.Or if you see one that starts a little late change that lamp as well.If it still starts slow ,change the ignitor.

Check your fst connections and make sure they are tight.


There are some things you can try.This is a solvable problem.Like sparky says ,more info ,as many details as possible.

Will the bed stay on if you don't lower the canopy?

Are you sure that when you hear the chime at various times the customer is not trying to lower the bed before starting it.This will change the flip over time.

Try turning off the breakers in the bed and see if it will run with no problems.This will tell you if it is in the lamps or the switches.

and finally order a new set of lamps from tan tech and speak to patryk.If you are his customer he will talk you thru this.

UV2021--May I just say thank you in advance!!

Yes the bed will run if you don't put the canopy down.

Not sure about the customers touching the arrow down button before starting the bed. (We try to ask, but they look at you like you are from mars!) Same thing when it shuts off early. We ask if they by chance hit the emergency shut off when trying to mess with radio. (Again Mars)

We shut breakers off on lights and ran the bed for 20 min, then flipped them back on one at a time all light came on, and ran fine.

However we have noticed on breaker 15, 1/2 of it is jumped to breaker 17, and this is done on about 7 of the breaker, but NOT ALL. Have asked our repair guy several times about this--he says no worries??

In checking FST connections, we noticed wall switch is run through the emergency shut off, is this correct?

Will give more info as we go.

[uv2021]

I mean will it run without turning off with the canopy up? I know that this is an intermitent problem,but when you lower the canopy it allows gravity to kick in .And if you have a loose switch in one of the trays this would cause it to open slightly and turn off your bed.So tape up the switches on the trays.There is also a switch under the top skin.Tape that up as well.These switches are not needed ,so you are not comprimising safety.

As far as the jumpers on the breakers...I have never seen that before.Those breakers are just square d 15 amp breakers which are commonly available and cheap.Just for the process of elimination ,replace them.(the jumped ones) You can very easily do this yourself.Or unjump them.That is not right.

Just kill the main power to the bed before you mess with it.The worst that will happen when you put the power back to the bed if you wire a breaker wrong is that it will trip.

Turning the breakers on one by one will identify a circut when it is broken,but with an intermitent problem it will not always say"hey it's me I'm the problem".That is why you nees to listen to the lamps for a buzzing sound ,or with a strong light examin the ends of the lamps ,looking for scorch or arching marks.

Wall switch going into the emergency shut off is fine,just as long as all connections are tight.Did the previous owner have these problems.

[tbtan]

Uuuummm yea. The previous owners bought the bed knowing it had problems and had every tom, dick, and harry trying to work on this bed. Of course none of this was disclosed at the time of purchase, we found this out by talking with ex employees. The first time our repair guy opened the bed, I thought he was going to fall over. Masking tape and paper clips holding things together everywhere!!! (No joke) Alot of the beds were like this! 13 blown caps and such.

Anyhow, we un-jumped the breakers and when we turn the bed on certain lights do not fire up.

[uv2021]

Try changing the breaker that won't light with one that will.You could have some bad breakers.


Just so you know ,your bed is like a map.If you start at the foot on the outer colum and count in towards the bed across the feet and those are lamps 1,2 ,3 the second group which will go across your shins are 4,5,6 ect ect until you get to the face which going from the outside(closest to you as stand in front of the bed) are 19,20 (direct over the face) and 21.

Now if you look at your breakers ,you have 2 rows ,the row closest to you are all the "odd numbers" 1,3,5,7 going from the foot of the bed towards the head of the bed.

The second row are the even numbers 2,4,6,8, ect.This way you can easily identify the right breakers in conjunction with the lamps.

That is assuming that nobody messed with all of them too badly.

But with the intermitant type of problem you are having I would want to get everything back to normal.

Steve
Again, thank you so much for helping people you don't even know from po dunk BFE. I love this hp bed, but sometimes I want to throw her in the trash! We will keep plugging away at your advice from above.

[uv2021]

It's a great bed.I once was running six of them.I now care for 4 .

[tbtan]

Hi, it's us again. So here is where we are: we re-wired the breakers, changed heat sensor, re did the lift motor circuit, cleaned out paddles, replaced the filters, and new limit switches.

Ran the bed 2x's and each time it is shutting off right before 1/2 time. She says thank you please make another appt, but time is still on the timer.

Now we have noticed the top is so hot you can't even touch it. The outside top of the bed. How hot is normal hot for this bed?

[uv2021]

There is a heat sensor built into the top of the machine.And it works.Is the air being vented out of the room?

Do you have make up air going into the room?

Do you have backdraft dampers? One may be stuck closed.

If they vent outside,did the roofers use a fine mesh on the outlet which could collect dust and reduce the air flow?

Does it shut off consistently?

[tbtan]

Back to the emergency shut off...the wire that goes to the safety switches. Can anyone tell me where they are? I do not see them in my wire diagrams.
