We are having some odd things happening with a system designed using DOUT HS + LS outputs.

We will start with the first group circled in Red below, but are having the same issues with the other HS + LS groups. You can also reference the schematic below for the HS + LS wiring for “Servo Power” and Front “Diff Lock”. This is with "DOUT under current detection" on.

• If Servo Power and Front Diff Lock both are False and we disconnect one or the other, the corresponding function will show “open load” as expected.
• If Servo Power is True and Front Diff Lock is False, and we disconnect either one, the corresponding function will show “open load” as expected.
• If Servo Power is False and Front Diff Lock is True and we disconnect Servo Power, no “open load” is shown
• If Servo Power is False and Front Diff Lock is True and we disconnect Front Diff Lock, both show “open load”
• If Servo Power is True and Front Diff Lock is True and we disconnect either one, no “open load” is shown

If we turn "DOUT under current detection" off, the outputs will behave how we understand they are supposed to. Although, doing so removes open load detection when the output is true. 

The instruction book recommends NOT using an MC4x for 33/75 hz Pulsar coils.

I have an application where we are using an MC43 driving PF coils, and the customer is asking for a retrofit to 75hz pulsars, for common coils with other equipment.    Is it possible to add external diodes/etc and drive these coils, or will we have to replace the controller?

What are the group numbers for these outputs? The manual doesn't list them in appendix A?

Hello,

This happens in a system with just an MC43, and no other connection than Ethernet.

Same hardware and software without problems on previous machines.

After successfully sent the project to the system (through Ethernet, and from IQAN Run or from IQAN Design ), when trying to go online the following screen appears:

(from IQANDesign 5 Latest version, after trying to go online)

(from IQANRun 5.01, after trying to get system info,or enter Adjust, or whatever)

It seems the module lights blink the following way:

4xRed,

2xYellow + 2xYellow + 1xYellow + 3xYellow

All short blinks...probably.

Any hint?

Thanks a lot.

.One of my customer receive this message , this is a MD3. I dont know why ?

I have a customer who has had 2 MD3's fail in 2 years. They are in Puerto Rico and they think this is due to the humidity. Has anyone else seen this? I personally have not seen the MD3 that they are replacing so I don't know if it is beat up or user error. 

The installation manual states an example for a 2 wire 0-20mA input into the controller, but there is no reference to a 3 wire input. Are these supported? I'm assuming it will be the same connections just the sensor ground (which does not include the signal) will go to chassis or vref -ve? Can anyone confirm?

l have an L90LS valve with proportional soleniods and would like to use a Joystick to operate which is the best choice out of parker range

where on the MC41 I connect LED lamp and how is it controlled it via the program

Is it possible to adjust the default time that Vdin buttons when pressed and held remain 'on' for?

We have a multi-master application using a MD4-10 and a MD4-7. On each we have momentary buttons commanding functions that are slow in operation meaning the button has to be pressed for some time- By default the buttons while still pressed go to the 'off' state by Iqan even though still pressed requiring the user to press again- this is not acceptable to the user. We cannot latch the buttons for safety reasons. The buttons seem to switch to 'off' after about 10-12 secs on the MD4-10 but longer (approx 20 secs) on the MD4-7.
