Standby mode for MD4
Hi everyone,
We want to adding a new feature on MD4 controller. When the system locked function is true, standby mode should be active because of energy-saving.
Best regards.
Freeze of the touch screen on MD4
We are using an MD3 and MD4 as screen on our system.
They print the same info from one CAN BUS
They are on the same system than a generator quite noisy, and when the generator start we loose the touch on the MD4, only the touch.
- The screen still work good
- the Md3 act normal
Did any body experiment the same kind of issue?
I don't have a scope on site I am investigating right now on the issue. I will try to
Power supply the MD4 from an other power source
Isolate the power suply if it doesn't work
I will try to add a capasitor if I have time.
M4 Safe Mode
I have a customer who attempted to move the location of an MD4 and in rewiring has got the wiring wrong! The screen will not now complete its boot up cycle and the diagnostics bus is not available to try to interrogate the machine.
There seems to be a tiny recessed red button alongside one of the screws on the rear of the screen - is this a safe mode button?
Wrong IdTag! Error on MD4
On two separate machines now (with identical systems) we have received customer reports of an issue of the IQAN system stopping functioning during machine operation.
On the MD4, the screen will say STOP System Message: IQAN-Master Wrong IdTag! system
I have been told that power cycling will not fix the issue. The only way to resolve is to unplug the Deutsch connector from the back of the MD4 and then plug it back in.
This is an intermittent issue. The machines can run 100+ hours before the issue repeats.
The customer was advised to check resistance on the ID Tag (resistance was correct) and to check the pins and wiring condition at the MD4 for any anomalies or corrosion (nothing identified).
Do you have any guidance on this issue?
Battery for MD4
I think that inlcuding an internal battery would be interesting in order to maintain RTC values.
Thanks.
fantastic display
MD4 problems when backlight is 70% or above.
If you adjust backlight in the MD4 higher then 70% the screen brightness gets unstable starts vary in brightness up and down.
MD3 and MD4 Operating temperature
in Catalogue of MD4 for operating, ambient -30° to 70°C
What is the lcd-off range of md4 screen?
Thank you in advance for your helps.
Abnormal white screen after startup on MD4
Has anyone else experienced a completely white screen on an MD4 after start-up but application file seems to work properly? The problem is very intermittent, it happened approximately three times during a week of testing a prototype (perhaps 100 boot up cycles).
Cycled ignition key off and back on to rectify.
