MD4 temperature

AxelC 4 years ago in Master modules / MD4 • updated by Gustav Widén (System support) 8 months ago 3
We are in Thailand where average temperature is 35 degree Celsius.

We have 2 MD4 on 2 project, they are hot when running, internal sensor tell 52 degree Celsius minimum most of the time. It is really hot on the finger, our customers are a little worried.

We also have MD3, they are also at more than 50 degree but we don' t feel it on the buttons.

Does all the MD3/4 get hot like this? Is there recomendation to reduce that?

MD4 10" screen

Richard 3 years ago in Master modules / MD4 0

Does anyone know how the 10" version of the MD4 is coming along. The last information I had was the unit was not released for production yet due to screen fogging issues. I hope that is resolved as I may well have an application for the unit.

Is the unit available for sale?

MD4 user inputs

Richard 4 years ago in Master modules / MD4 • updated 2 years ago 2
I want to use multiple MD4 units on a new project but the problem is in our application the user may be wearing gloves so I am not sure a touch screen is useful. My first idea was to put a CAN open tactile button pad by the side of the MD4 unit but have come up with a blank.
I have tried - Grayhill - Graf-Syteco and powerkey so far who do have keypads but they do not have a size or shape currently in production that fits nicely alongside the MD4 (7").
Does anyone have any ideas?

Speaker

Metalfor 3 years ago in Master modules / MD4 0
Hello. I've found in MD4 displays that the only way to handle sound is with one low side digital output for buzzers. The displays have very good screen definitions, excellent images design tools but need internal speaker to give to end users an auditory experience according to the others senses involved when use Parker's displays. I suppose that the only negative point is the IP degree of display will decrease. Bet regards. Diego.

Faulty/broken MD4

L.P.C 2 months ago in Master modules / MD4 • updated by Cole Koster 2 weeks ago 4

We have had multiple MD4 units (7 and 10 inches) no longer powering up.

Do you have any idea what could cause that?  We're using fuses to protect the units, but sometimes they still seem to fail on normal operation.

MD4 touch screen not responding

Jean-Marc Zanni 3 months ago in Master modules / MD4 0

We use the MD4-7 for all our systems.  I have one of my customer with a Fairly new(3 years) but rarely used unit for a test bench.  He complains and I witness that is touch screen is often not responding.  It is mounted on an aluminum test bench.  Sometimes if he moves the unit away from the bench it seems to respond better but not always.  We tried to ground the unit but it did not improve.  Do you think this is an hardware issue or is there mounting issue we need to look at?

MD4 Graphical Error?

Kevin Arscott 6 months ago in Master modules / MD4 • updated by Matthew Herzig 5 months 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:



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?
