The MD4 documentation states to use 1.5K ohm resistor on the +RTC circuit. Is the 1.5K ohm the only type that is usable, or is there a range that will work?

The MC43 documentation states to use a single 40A external fuse to protect the module. Is it sufficient to run two single 20A fuses, one on each +BAT connection?

Hi,

We have installed a speed sensor (PNP, 15000Hz) onto a MC42 frequency input (pin C1:28, PD).

The problem we have is that the raw value only goes up to about 2800Hz then zero's out with no further reading and we need to get a reading up to at least 5500Hz.

I have configured the input settings to: Max HZ -> 15000 and also the Scaled Maxed-> 15000 to mach the sensor's capabilities and then use the raw reading to scale a RPM value.

We tried adjusting the sensor closer to the ring gear, but no improvement.  

So I did a test to see if it might be the sensor that is faulty by connecting the sensor to a different type/brand of controller. It immediately worked and gave the correct reading constantly.

The question is now... What am I doing wrong on the IQAN side? 

What can be the cause of this error ?

I have a MC43 with the following blink code 4 red, 2 yellow, 1 yellow, 1 yellow, 1 yellow. What do the 3 yellow blinks at the end mean? This happens intermittently when the module first gets power.

I am considering using an MC41 with PWM signals as inputs. These signals come from joystick thumbwheels on excavators made by a large multi-national OEM. My problem is the spec on the frequency of the PWM signal from the thumbwheel is 500Hz +/- 50Hz. I see the max allowable frequency from the MC4x catalog is 500Hz. Wondering if the MC41 will work with 550Hz PWM frequency input.

How this can be done? Did not find from channel properties.

I am using MC41FS in non safety application. During cranking voltage drops, but not low enough to reset module.

Module hangs up and stays that way until power recycle. Can I restart application back up with SW?

Anyone have more information about the error 1:20 on a MC31 master module ?

I didn't find anything related to this error.

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.
