Can any tell me if its possible to use a PT100 Type S temperature sensor on a voltage input in a MC43?

Hi everyone,

I have been working on a quite complex system. When using XC10 all relay coils (or valve solenoids) controlled by DOUT(LS) have been powered from +BAT and it has been working fine. However checking program, for no reason, have found in the the Instruction book that one or more DOUT should be used to power these coils or solenoids. Is there any risk with what I am doing ? I have checked that for MC43 and MD4, that I have been using on the same system, it is allowed to use +BAT for power. I can of course do it by book but the program would become a little bit awkward and messy.

Any comments will be much appreciated

Hello,

I have a situation where need to get data from a weigh system with RS485 modbus onto the canBus and in to a MD4.

Can you suggest a gateway that I can use for this?

Cheers,

When using the MD4-5 in portrait mode are the large C1 & C2 connectors at the top or bottom of the module?

has anyone experience this issue before, got an MD4-5, it will not go pass the start up screen with the parker logo on it.

have load a new blank app to try and reset it, but issue remains. any ideas

I am designing a new system where the customer has to send me a 2 wire 4-20ma signal to monitor. I can add a resistor to convert it to a voltage input, but I would prefer not to. The manual shows a 3 wire hook up, if I were to not use the Vref pin, would this still work? I am not concerned about the output getting out of scale, and when we do a startup I can calibrate it to the PLC actual range... 

Should this work?

This is a two part question regarding the criticality of VREFs for IQAN Modules.  We use an MD4 and XA2 in our system.  On the XA2, we use VREF to support a three axis joystick and one pressure transducer (4 VINs).

We received a report from the field that a short circuit between VREF and ground caused the XA2 module to fail completely resulting in "I/O No Contact" IQAN Error Message on the MD4.

Is this a typical or expected failure mode for an XA2 with a damaged 5V reference voltage regulator?  Or is it more likely there was a mis-diagnosis from the field?  I can't think of a way to validate this without destroying an otherwise healthy XA2.

Would this also be the case in an MC42?

I'm having an issue where the PWM outputs jump in voltage to battery voltage seemingly randomly and with no change in the displayed output on IQAN run. Anyone know what is going on?

We had a XC42 where we use a hall effect analog device that was mapped to pin 8 and configured as an analog input. The device was connected to Vref A so uses a supply voltage of +5v and provides 0.5-4.5v thru 180 deg of rotation. We first started to see it only indicating from 2.5-4.5v and then eventually we got fixed values that fluctuated based on if the hall effect magnet was present or not. After some trouble shooting we removed the wire from pin at a connector and were getting a fixed voltage of around 4v at pin 8. With this removed the magnet rotated gave us 0.5-4.5v at the output of the sensor.

A data sheet of the sensor is attached. Model # is RTP180LVNAA

We ended up remapping the input to pin 52 and it all worked fine again.

It almost seems like the pull up resistor in the channel was "turned on"???Honeywell RTP Sensor
