What are the group numbers for these outputs? The manual doesn't list them in appendix A?

Hello,

This happens in a system with just an MC43, and no other connection than Ethernet.

Same hardware and software without problems on previous machines.

After successfully sent the project to the system (through Ethernet, and from IQAN Run or from IQAN Design ), when trying to go online the following screen appears:

(from IQANDesign 5 Latest version, after trying to go online)

(from IQANRun 5.01, after trying to get system info,or enter Adjust, or whatever)

It seems the module lights blink the following way:

4xRed,

2xYellow + 2xYellow + 1xYellow + 3xYellow

All short blinks...probably.

Any hint?

Thanks a lot.

.One of my customer receive this message , this is a MD3. I dont know why ?

I have a customer who has had 2 MD3's fail in 2 years. They are in Puerto Rico and they think this is due to the humidity. Has anyone else seen this? I personally have not seen the MD3 that they are replacing so I don't know if it is beat up or user error. 

The installation manual states an example for a 2 wire 0-20mA input into the controller, but there is no reference to a 3 wire input. Are these supported? I'm assuming it will be the same connections just the sensor ground (which does not include the signal) will go to chassis or vref -ve? Can anyone confirm?

l have an L90LS valve with proportional soleniods and would like to use a Joystick to operate which is the best choice out of parker range

where on the MC41 I connect LED lamp and how is it controlled it via the program

Is it possible to adjust the default time that Vdin buttons when pressed and held remain 'on' for?

We have a multi-master application using a MD4-10 and a MD4-7. On each we have momentary buttons commanding functions that are slow in operation meaning the button has to be pressed for some time- By default the buttons while still pressed go to the 'off' state by Iqan even though still pressed requiring the user to press again- this is not acceptable to the user. We cannot latch the buttons for safety reasons. The buttons seem to switch to 'off' after about 10-12 secs on the MD4-10 but longer (approx 20 secs) on the MD4-7.

Has anyone had any experience whereby they have used a single IQAN PWM out with a 5A load ?  The data sheets say "no" but I am just wondering if this is possible if the number of outputs used simultaneously, is controlled.

I have a MC41 setup where I need to use a bidirectionnal CAM output in PWM mode to drive a bidirectional valve (2 coils). There is a mention to not use a flyback diode in closed loop control but is it ok to add diodes on coils if the outputs are used in PWM mode, not in current output? I tried it and it seems to work just fine.

I want to add diodes as there will be an emergency operation switch installed to directly power the coils. We want the diodes to prevent high voltage spikes to the MC41 module and the switches.

Found on the forum:

With IQAN-MC3 and IQAN-MC43, -MC42 and -MC41, the internal clamping diode is not disconnected when COUT pins are used as open control PWM.

Does that mean that we do not need to add diodes?
