Polar 115 problem

The air tables on my Polar 115 just stopped working. No error code on the display.
All other functions are working. Went through manual, no help. Any ideas??

Mike

 

Many ideas!

I am sorry but in this case the information Polar 115 does not really help. The model 115 was built from 1969 until today. And this includes six different machine generations. We should leave this for the question at the end. I am writing this, because newer machines (with CRT – with a display) have an icon on the screen (just beside the symbol of the backgauge). Using this icon you know your order (swithcing the air on or off) is understood or not. It could be the switch underneath the front table gave up. Maybe we leave test this for a local electrician. There are other things you can do. The next things I would check are:
Is the blower running, if not ask a local electrician to check the overload switch.
If the blower is working, let one person switch the air table continuously on and off and on and off. During this listen to the valve (round part with the plug) or just put your hand on it. Does it react? Can you fell or hear a clicking? If not ask a local electrician to measure the power supply at the plug. Older machines have 42V to 48 V d. c. supply and newer machines have 26 to 28 V d.c.
If there is no power supply (in case the air table is switched on) you need help. If would ask binderytech.com. This is the closest specialist I know. Maybe they know somebody in your area. A question is always free of charge.
If there is power supply (in case the air table is switched on) you may try the valve in another equivalent machine. It maid be not so easy to find a machine and somebody allowing you to try. In this case we are back to help.

And at the end it would be nice to know which type of machine you have. There is a name plate above the gearbox with the type and number of the machine stamped on it.

Good luck

I called a local cutter mechanic and they said it was an overload. Reset breaker and all is well.

Mike

 

Area cutter mechanic was able to diagnose over the phone. I had told him icon appeared on screen, hear valve click on but nothing from the blower.
He told me where to locate the breaker and to hit the reset.

Thanks for the response,

Mike

 

Well done

Good luck

The overload switch is unterneath the the front table. You don't need to open any cover.

I dont see an overload switch. All I see is the on-off switch for the air table.

 

The "ON-switch" is beside the mechanical hand fine adjustment of the backgauge. The "OFF-switch" is one of the cut bottens. The on-off switch in the grey cover is the overload switch.

Maybe they have shut it off in the program stage. Ill look again when I have more time. Thank you.

 

I would check:
Is the shaft inside the blower motor rotating?
If not, check the power supply at the motor, maybe by an electrician.
If yes, check if you have the icon on the display active, in the moment the air cushion is switched on.
If not, check the “ON-switch” underneath the front table.
If yes, check if the hoses (distributing the air to the jets) underneath the table are okay and do not lie on the floor. Just watching is enough.
If the hoses are okay maybe the valve is not working correct, or a filter is dirty (depends on the type of blower). The blower is nothing but a fan with a valve.
You wrote, you are hearing a click. This normally means the valve is working.
Maybe a technical person takes a look.

Hi sir:

Test if

1) Blower motor are running ?

2) If Not, reset the overload thermic Q92, most of them has a small potentiometer for increase the amps, see what amps position is, and increase with screwdriver 1 amps more. Tight the cables for Overload thermic Q 92, and see if the terminal of blower motor are o.k, tight very well the wires from motor too.

3) The switch S87 activate the magnet Y94, for the aire is coming to the table. see if the switch activate the Magnet valve is open, if open see if there are some hoses loses, and tight the clamp.

4) If the magnet Y94 is NOT open ,the electronic board SK, the small relais K2, can be dirty or defective, try to clean the contacts, or replace IT the relais, the magnet active with +25Vdc.

 

Q92 was indeed tripped. Reset for now. We'll watch and see if it trips again before we adjust pot. Thank you !

 

Ok sir Good , remember to adjust the POT , before to Trip, NO after.

Always happen that, to do to the Cycle of motor work.

Remember all electrical motor, the international standard, is to clean, LUBE, exchange ball bearing, is every year.
