How is the performance proportional pressure control devices, such as a Parker RE06 without on board electronics, using Parker MC4* current output channel? The Parker industrial driver, PCD, uses a 10kHz PWM frequency to drive an RE06 coil. The Parker MC4* has a current output PWM frequency limit of 500 Hz. I have driven an RE06 coil using Iqan products in the past without noticeable performance issues, but wanted to see if others have done the same.

Thanks

For future projects I need a touchscreen display with a size of 12 ".

Is something planned in this size?

4 red flashes, followed by a yellow flash sequence of 2-2-1-3

This continues to happen when trying to start the engine of the machine. As if maybe the battery voltage is going too low momentarily.

Once in this state, the IQAN module cannot be communicated with using IQANRun 5 and is not operational until powered off then on, but will deliver the above flash sequence. 

Any help would be appreciated.

Dear Gustav.

Could you please tell me if the MD4 is ISO 26262? 

Regards

We have a customer with a MD3 that sometimes works fine and other times just displays this error message. Its running a IQAN Version 2 program.

+AT+IPR?$dAT+IPR?$D

We will replace the display, just curious what is going on.

Thanks

I have an MC2 that will not accept a new date/time.  It's stuck on 01/01/2001 - 00:00:00.

I connected to it, and used IQANrun to set date/time, it says it was successful, but the date/time didn't change.  I rebooted the system, did not help.

J1939 TDA is disabled for this machine, RTC is enabled.

Wondering if anyone has seen this before....

Hi all,

I'm currently testing an MC43 on our HIL bench and notice some issue with the low side driver at startup.

On our system, all the low side driver of the MC43 at pulled up to supply voltage with a 10K pull up resistor.

The problem is that when we switch on the ECU, it's going into error with the code 4:2.

We find out that by waiting 1.5 sec at startup before pulling up the low side driver fix the problem. 

The problem is that on the vehicle we will probably end up in this situation as some low side driver are going to be pulled up throw some relay coil. 

Is the unit is going into error if any low side driver is pulled up or only some of them trigger it ?

Thanks for your support,

Grégoire

I am trying to read a NTC thermistor with a resistive output ranging from 810 - 76.9 ohms on the MC43. 

In the past we have used a voltage divider circuit to read the sensor value on a VIN channel, but if the MC43 could introduce a bias current to the thermistor then the output voltage could read without the need for a second resistor in the mix. 

I did not seeing any mention of this in the MC43 manual but was wondering if anyone has faced this challenge before. 

Thank you.
