9V valves

Theleo De Bruyn 6 years ago updated by Gustav Widén (System support) 6 years ago 0

Dear reader,


I need for an aplication a proportional  9 Volt output. is this possible with the system running on 24 Volts? Because if i would use a COUT the voltage would be 24 V.


Is it maby possible to use a PWM output? 

if so, how do i use PWM?

Another option is to run the system on 9V, is this stable to use?

over voltage possible?

Theleo De Bruyn 6 years ago updated by Gustav Widén (System support) 6 years ago 3

Dear reader


we need for an aplication 4 Voltage inputs on one of the MC4x serie, those voltage inputs aren't a problem but we need to have voltage inputs for 0-7 Volts. is it possible to connect those sesors on the voltage in for 0-5 Volts ,0-5 Volts will do the job in our program. this 7 Volts on the input isn't continuous, these are just peaks.


Thanks for the help!

MD4 Graphical Error?

Kevin 6 years ago in Master modules / MD4 updated by Matthew Herzig 6 years ago 4

We have a customer that is experiencing graphical errors with an MD4. S/N 1535280044. Customer is complaining that the display sometimes is black, sometimes white and sometimes multicoloured lines:


Image 1324


Does anyone know why this could be happening? It appears to be happening sometimes at startup, but also when machine is running (randomly dropping out). Im not sure if its the hardware issue that was changed a couple of years ago on the MD4?

Connectivity Question - MDL2 and MD4

Nick Pridham 6 years ago in Gateways updated by Gustav Widén (System support) 6 years ago 1

I would like to define a common remote connectivity solution that works across MDL2 and MD4 machines. 

Will G3 work on both?

I can open up an MDL2 application file in IQAN Design 5.03,  add a G2/G3 modem, connect them both to a diagnostic bus and save the file.  

Will IQAN connect work properly ?

XA2 DOUT problem

Stefan Hedlund 6 years ago in Expansion modules / XA2, XS2 updated by Gustav Widén (System support) 6 years ago 1

I have encountered a problem with DOUT on XA2 modules. We operate several Parker D1VW (NG6) valve, with multiple XA2 modules. Some DOUT (from different XA2) does not activate the magnet coil, although it looks completely correct when I'm connected to IQAN Design . DOUT = Tru.

We use valve contacts with zener diodes, it works on most DOUT otherwise. I had to change the output to PWM instead and then it works without a problem. Is there any problem with the XA2 modules, or are the Zener diodes that do not work against XA2?

xa2 voltage drop

Ed Schippers 6 years ago in Expansion modules / XA2, XS2 updated by Gustav Widén (System support) 6 years ago 1

Due to a voltage drop in the system, because of an electric fan switching on, all the voltage inputs give a low error.

The strange thing is that the voltage drop is not so big. it drops from 27 to 22 for only a sec due to the high start current of the fan.

Is this normal, I thought the modules could be used in 12 VDC system also. So the voltage drop should not be a problem.


regards,

Ed

MD3 on borrowed time?

Forrest 6 years ago in Master modules / MD3 updated 6 years ago 2

I was told some months ago, the the MD3 would be obsoleted sooner rather than later, but I have not seen anything further on this.

Any idea how far out is the timeline on obsoleting the MD3?

CIN Problems sensing on MC41

James Howland 6 years ago in Master modules / MC4x updated by Codie 2 years ago 12

I am using an IFM Efector 4-20mA 2 wire sensor on the MC41 inputs capable of sensing current.  Their hookup diagram is what I expected connecting one side of the sensor to high and one side to the sensor port.  The input shows a high error when I'm in a neutral state and I can confirm with an ammeter in line that I am sending 4mA to the controller.  My best guess is there is too much impedance and internally it is not correcting for it so I tried adding a 5k resistor to ground externally to split the current.  It now senses 3.8mA but is no longer accurate over the range.

Password protect projects

James A 6 years ago in Gateways / G11/G12 updated by Gustav Widén (System support) 6 years ago 2

When the G11 Bluetooth Modem was still in BETA one major limitation was that you could not flash a password protected project.  


Has the limitation been resolved?

IQAN-DG Display failure

David Kiu 6 years ago updated by Lennart Hedlund 2 years ago 5

Hello admins  & all,

I bounced into this forum while searching for information pertaining to IQAN-DG instrument.

My problem is that the display is distorted or rather damaged. On the printed circuit board, it stateds DMF5001NY-LY  Org_DMF5001NY-LY.jpg . I managed to acquired a new display unit DMF5001NY-LY-ATE-BBN . After installing, this display unit seems not compatible! The resolution of the text seems

weird, enlarged, cut-off and shifted to the right side Text_res1.jpg Text_res2.jpg.

As i am lack of technical information regarding the screen resolution, i am lost here. I assume this is a resolution problem with the new display unit.

Any information, help or solution to this problem is greatly appreciated.

Regards

David
