Hi to all

Is it possible to connect the terminal W of the engine alternator to terminal C1:24 "Frequency In" of the XA2?

The diesel engine work at 24V , it is an old engine and don't has the J1939 bus.

XA2 No contact error. The led indications on the XA2 module are fine. All XA2 modules  after this module on the expansion bus has status OK. Could Anyone point out what is going on here Please?

Can I know the XC10 POWER CONTROL input consumption or input resistance?

I cannot find this data in the iqan-xc10_uk_instructionbook 2016...

Thanks in advance and best regards.

On the XC4x serie there are multiple Vref+ and Vref- and on both C1 and C2 

Are these interaly connected in the module? 

Or are they seperate from eachother and serve only dedicated Vin's?

Best Regards Ed

I'm using the expansion module XC43 to control valves, usually, I use Cout to control proportional valves but I run out of current output pins " I have 13 valves" I'm wondering if I can use PWM OUT HS to control D1FBE01HC0NJJ3 " Proportional directional valves in general " also L90LS, P70? Because it seems for me that PWM is only to control pulsar valves that have some frequency working value.  

I'm being asked to mount modules external to the main enclosure, XC41's to be exact. So there will be an enclosure to mount the MD4 to but everything else will be mounting on the rock crushing machine. The power and ground for the modules will come from within the main panel and be fuse protected. The issue I'm having is trying to solve the ground and power that is supplied to the DIN's and DOUT's. Is there a way to cleanly create a ground line and power line to run along the machine and tie into for each necessary I/O? I was thinking of a isolated buss bar, or perhaps a two to one butt splice. Any ideas will help.

Our usual setup is an MD4 with an XC4X expansion module. But we end up using an MC4X because we need the CANBus available on the master module. It would be nice if the expansion module provided access to additional CANBus the same way it provides access to its IO.

What sort of symptoms might I expect with an expansion module failure?

Will D-outs become intermittent? 

would anything else become sporadic?

Are the modules smart enough to realize something is wrong?

I have an MD3 running a small program and an XA2 expansion module.   When connecting only power , GND , Can-H, Can-L and ID tag #3 to the expansion module I get a four red LED blink with no Orange/ Yellow.

No connection message on the MD3.    

The ID code in Iqan Deisgn is the same as ID tag. 

Hello,

I have an H-Bridge that drives a DC brushed motor on 12V. I need to determine the PWM ratio being supplied to this motor by the H-Bridge. There is no other signal that could get me this information so I am contemplating hooking both sides of this motor to PWM inputs on the XC-23. Before doing such a thing, I looked at the signal using an oscilloscope. Basically, the signal is 0-12V most of the time but dips below 0V when the ON time finishes. The lowest voltage read with the scope is -11V for a short period of time.

There are no Absolute Requirements for negative voltages on inputs in the datasheet of the XC-23. What is the absolute minimum voltage that can be applied to a PWM input of the XC-23 without damaging it ?
