FGRM-222 stopped working

[petya22 0]

Hi,

 

I´m using about 6 FGRM-222 Roller shutters for approx 2 years now (with Openhab 1). Everything worked fine until yesterday one of shutters stopped working as it should do. I was surprised in the morning as roller blinds driven by this shutter were still closed. I then manually tried to open them, but they just moved about 10cm and stopped, So I had to click several times to get the blinds fully open.

I´ve disconnected the roller shutter from the power grid, but it didn´t solve the problem.

I also started the calibration process (config param 29), roller blinds just fullye opened and nothing else happened. So afterwards the behaviour is still the same: they move in 10cm steps.

I didn´t change anything, the system worked fine for 2 years.

Setting config param 10 to 1 also didn´t help.

 

Kindly help on this issue.

Thanks!

This is a long shot, I'm not a specialist of this particular module, but I think it has electronic over-current protection. I'm certain that it has power measurement, so in Fibaro tradition I'd expect it to have a limit (both for peak power and long term power) and turn off after 2 seconds in case of overload. Maybe, over the 2 years, the load increased (faulty motor? mechanical problem?). To eliminate that, I'd connect a light bulb. Specs (from the manual): 4,2 A for lamps and resistive loads 1,7 A for motors with compensated power factor (inductive loads). It's a long shot, I'd wait until other users join this topic.

Or do a swap out with one of your other working ones  to see if its the unit or blind or wiring.

If the blinds are the same size  you could start swapping them first before undoing any wiring

Its a process of elimination

Thanks all for your hints!

 

 

I´ve disconnected the module completely from the powere grid again, reset to factory settings, re-included and it works as before.

Still no idea what and why happened...

Hi,

 

Same symptons for me. My FGR worked fine for quite some times and suddenly it will only move for 0.5 sec and stops. It takes me now 15 attemps to close my shutters (it's been used for swing shutters)

 

Following the above solution I tried to reset .. press B button for ca 14 sec but .. nothing no led blinking ??!!

 

Why is that ?

Is there a way to acheive the same thing with a command_class_configuration ?

I managed to reset the device by excluding it because I couldn't do it with the B Button ..

1- Why I coudn't achieve  reset  using  the B button  .. I pressed the button  for 15 sec  .. nothing .. is this a sign of a faulty device?

2-  following the reset .. I could open and close my swing shutters but when I request the calibration it will operate for 2 sec and then stop !!

 

So it seems like a protection of some kind is stopping the process ... could be over current .. 

3- How can I verify / assess this ?

 

Help please !!

Sorry, no wise words... Measuring currents (especially short pulses of high current) is not very easy. Also, the module could be faulty, the wiring could be faulty... Maybe the button of the module is broken. After 14 seconds, do you see a yellow LED on that module? If you click again when it's yellow, the module should restart and would no longer work on your controller. If your controller can still control the module after this procedure, the reset did not work.

 

As I said I have only basic knowledge of this module.... Maybe someone else can give some better advise. For example, maybe it is possible to attach a different load and see how that behaves...
