ISM problem - should I just buy a switch

Postby rickystyx » 30 Mar 2021, 19:10

The ISM on my R-net system doesn't seem to work - I've checked all the connections and they seem fine -there is only one actuator for the tilt so what I'm wondering is if I should spend less than £5 and simply fit a momentary DPDT switch to operate the tilt instead of paying £70 to £140 for a new ISM
Anyone got a good reason not to just fit a switch instead of replacing a rather complicated system?

Just make sure you do something to make sure the actuator can't stall at end of travel. If it doesn't have them, you will have to add limit switches and diodes husky enough to take full motor draw.

The ISM on my R-net system doesn't seem to work


Has it STOPPED working? Or is it some new configuration and not set up properly in programming? Because 1 bus lead and 2 wires for the actuator is easier than wiring up switches etc and a supply.

It has never worked since I got it but I don't know if it could be programming - when I connect the dongle it tells me that there is a module fault - it also shows that by the eight flashing LEDs.
I can't see anything obvious in the programming but it is possible because I am only guessing since I don't understand it enough.
I haven't been bothered by it but to get the chair in the car I need to lower the seat enough as it is a tight fit and hat can be done by hand but there are occasions when I am bird watching that putting a tilt on would be really helpful so I thought I would have a look.
I thought about the switch as a way of just testing the motor out and then thought why isn't it just done like that I can see when it is fully up or down or I could add limit switches.
I'd just like it to work but as you suggest it might be that it was locked out in the program and I just havent found the right thing yet.
Is there something obvious I should be looking for?
I did check the wiring on the ISM and it appears there is no choice as to where things are plugged in so I don't think it's plugged into the wrong socket as all the others are blanked off although the r-net manual shows that the tilt should be in socket 3 and it appears to be in socket 4 and 3 is blanked off

I'm tempted just to buy one but can I be sure that it is the ISM that is the problem - would a fault on the power module give the same error report or is the system cleverer than that?

If it all works normally without the module it must be the module? Might be a duff bus cable.

One thing. You seem confused by the modules. The seating module SM only works with the 90A power module so it cant be that unless you have a PM90L power module.
The Intelligent Seating Module ISM works with the 60, 80, and 120A power modules.
The CxSM is different again... And like rocking horse shit on ebay and not needed for your use. I doubt you have one. Most of these are 6 channel ISM or if used with a PM90L could be an SM and it only works on that power module - no bus cable.

Nothing cheap on eBay at the moment. But you can make an offer...

There appear to be various different model numbers of ISM being sold and none of them the same as mine which is D50919.03 can you use any of them or are there differences?

ISM with lights and ISM without on this page.

And SM, and CxSM too.

You are almost definitely only going to find ISM 6 channel with lights in europe. And maybe without lights in US. Everything but the SM will work!

Well my tilt is now working again - Thanks all
Just wondering if I need to download my settings again to be safe with this new module or if all the settings get kept on the power module.
I'll probably download it again anyway to be sure

Will do - just wasn't sure if the module settings remain in the module - if they do the current rating set may be more than my little motor will take as they are set at 2A and 3A in the original program
I'll download from the chair and see what that is set to then I might have an idea as to where the settings get stored or not if they are the same :eh:

Yes all the settings are stored in the power module. So any other modules or joysticks are just plug and play. This includes settings for modules that may be absent. So if you have no gyro, then its settings may be in the settings file, and so displayed in the software. But they are ignored if the module isnt there an or is set to "Is Gyro fitted: NO/YES" although its settings will remain. So that on a typical stock chair you can say plug in a switch box. or attendant control. All pre configured.

In other words, everything on your OEM softwares laptop screen is saved to the settings file, and then to your power module.
