Good Morning,

I have completed my first project in IQAN Design and while looking at the project documentation, I noticed what would seem to me like an error. Please see the attached screenshots on how the one pin list  shows pin C1:4 under the Master Module as being ADDR-L and under the Gateway module it shows C1:4 as being CAN-H. What am I missing?

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 just updated from IQAN 3.19 to IQAN 4.06.

We are now seeing over load errors on several solenoids being controlled with PWM out signals.

The overloads only occur when the outputs are off. When they are on (90% Duty cycle) the errors go away.

I believe I remember reading something about circuit failure detection being active even when outputs are off as part of an IQAN 4 update.

Any recommendations on how this could be resolved?

Is there a way of detecting how much current draw there is on the VREF supply on an MC3?

I have experimented with a SIL2 pressure transducer connected to an MD4 (don't have an MC3 to hand) and noticed that disconnecting the -VREF and leaving +5V supply and VIN signal wires connected to the controller will generate 2500mV signal into the MD4 VIN. This is not desirable as it simulates a pressure in the system which is not true. I can only imagine its how the internal electronic circuit is manufactured inside the transducer causing the false signal, but its not unique to one manufacture of pressure transducer. The current consumption of the sensor drops from 6mA to zero when the -VE is removed, wondered if this would be a good way to detect disconnected -VREF connection?

Aside from the method above or monitoring for a sudden change in VIN signal within the software, can anyone suggest any other solution to this issue?

One of our field units is getting the an "Error" on start-up. It occurs on every startup.

After the error is cleared, everything is working fine. The solenoid(s) showing the error function with no issue.

In the past we have seen open load and overload output errors but not just a generic error message. We replaced the MC3 module and the problem was resolved.

Just curious on what this means? Thanks

Hello,

I have a drill rig (Geoprobe 6712DT) which has an MC3 Module installed. Recently, the hydraulic pump would intermittently would stop building operating pressure, and the only workaround I can find is to bypass the MC3 Module and manually force the pump to build pressure. The Module is giving me a 1:2 error code, or "Input" error. Could someone help elaborate what this error could mean in the general sense? Any info would probably help with my troubleshooting. I'm guessing it could be something as simple as a loose wire, but I can't seem to find any so far.

The drill rig comes with the MC3 Module installed, and has worked fine up until recently. The manufacturer doesn't really provide any troubleshooting in regards to said module, so I'm kind of just winging it. The manual for the module tells me that it is an Input Error, but I'm not really sure what could be causing that.

Thanks in advance for anyone who can help me out. My apologies for being somewhat ignorant as to this thing... I'm just a humble driller.
