Any technical reason for using both +BATT pins on MC43?
We have specified an MC43 over the lesser modules in the range because of the additional inputs we need to monitor in the controller. We are not using any outputs on the module therefore current draw is minimal.
Is the only reason there is a second power supply pin (+BATT) to drive the additional outputs that can be configured on the MC43? Because we are not using any outputs (therefore current draw is hardly anything) can we connect only one of the +BATT pin to the supply, is there any technical reason why this cannot be done? I don't have a module to hand but I assume they are internally connected? is there a current limit on the module outputs if we only connect one pin?
I have had a look through the manual, the diagram on page 58 suggests we need to connect both pins on MC43 module only.
Used MDL2 modules
I have 4 used MDL2 modules (one with sim port, three without). If you are looking online and can't find them, let me know.
Reading value of a PWM valve with a PWMIN
Hello
A stand alone system have 4x PWM proportional valves in 24VAD. I use a MC43.
I like to ready this PWM value so that my system can give the right amount of oil from the variable pump.
I like to use the PWMIN. IN_33 and IN36 are for 5Volt sensors. Can I still use this INputs?? or do I need to use IN-37 and IN_38 because they are the only one rated to 24V. Can I somehow use a resistor so that I can use the 5Volt PWMIN.?? Sorry: I am not sure even reading you documentation.
50 kbps Component on 250kbps J1939 Bus
Will connecting a 50kbps component to a 250kbps J1939 bus cause the bus to shut down. I can change the baud rate to 250kbps later, but will I even be able to send the message to change the rate? The messaging would be from a MC4x series is that matters.
Terminal Resistors
Are terminal resistors needed when programming MD4's or do they already have an internal termination resistor?
MD4 Display Controller Certification
Hello,
Our company is using the MD4 Parker Display for the logic of the exterior lights system on a electrical vehicle. We are currently in the process of certifying the system for the FMVSS 108. In said certification, there is a minimum amount of cycles that the lighting system has to respect. Usually however, the system contains a module that does the logic and in our case that logic is in IQAN. So is there an equivalent for the MD4 module, like the MTBF(minimal time before failure) for example, to prove that the exterior lighting system can support 175,000 cycles.
Thanks for your help.
CIN
Hello. I am testing my MC41 application using a Eurtherm G-438 ( https://www.farnell.com/datasheets/1658070.pdf?_ga=2.178838692.143399012.1654225772-1786236872.1616697046&_gac=1.2754052.1650585147.EAIaIQobChMIlfWcop-m9wIVTsLCBB0Krwa-EAYYBiABEgKL5PD_BwE) signal conditioner to generate a 0-20 mA to simulate one of my inputs. The MC41 is latching onto a high error and I am puzzled as to why. I checked the output of the unit and it is in the proper range. I made a work around using a trim-pot but I want to be sure that I won't have problems when the controller is connected to its real current source. I noticed that the voltage compliance of the signal conditioner is 12 VDC max whereas my controller is receiving 28 VDC power currently. Could this be the error?
MD4-7 re-boot can't handshake
Hi
The situation happened after flashing software for MD4-7. I can't link to MD4-7 via CAN or Ethernet now that means i can't flash software again. The system still appears images but it will enter blue screen state like photo if i sent some commands to MD4 by any CAN channels. I try to shortly connect address PIN to enter safety mode but seems no influences. Who has any suggestions for me to solve this issue ? How to re-flash software MD-7 ?
Connector packed with di-electric grease
Got this photo from a colleague who works in after-sales, an MC41 connector packed with di-electric grease.
The Molex MX123 is a sealed connector when properly assembled, so adding di-electric grease does nothing to improve protection against water and dust. Instead, it can only cause problems by getting in the way for the pins and prevent contact.
I do not know how widespread this problem is.
Do you guys also have problems with people putting grease inside the connectors?
