Need Help!- Gecko 540 and Coolant Help

[SpeedsCustom]

I got working tonight on my enclosure and more wiring. After many many months! I finally have a relay board again that is controlled by my computer, M8 and M9 here we go! I really get annoyed with the unplugging and plugging in of the coolant cord and having coolant run when a file is done


ANYWAY! I got my Hal file set-up in EMC2 for the coolant to run. The coolant does turn on now with EMC!!!! The relay works, the 540 controls it, it's great.


However, When I disable the Gecko with the E-Stop, the coolant comes back on?

I have Pin 1 in EMC2 as E-Stop and Pin 17 as Coolant- Pin 17 is really Terminal 5 on the Gecko. I don't have the E-Stop wired to Terminal 6 on the 540 but rather terminal 10 (Which the manual says). I'm in no real rush as I need to wire everything accordingly.


Any ideas?

Your'e likely going to need to provide a little more info. Are you using the EMC2 screen E-stop or do you have a physical E-stop switch? How is your pump and relay wired into the Pos 5 output? How closely does your wiring match the suggested drawing in the g540 manual?

[SpeedsCustom]

I have a physical E-Stop, when I push it to stop the 540 the pump goes on. I'm using a relay board from CNC4pc. It tuns the signal to Terminal 5 on the 540 and the GDN to GDN on the 540, a separate 5 vdc supplies the the relay. It's really straight forward.

The pump is wired directly to the relay (one wire) and plugged into the wall.

If it matters, I disabled the charge pump on the geck540 by using the switch.

when the estop is pressed, does the g540 go into a fault mode? if it does, then would it not be correct to assume that all the functions of the g540 stop working? Which would in turn reset the relay board?

I do not know, Im thinking out loud.

it could be youhave the Hal backasswrd. Relays have normally open, and normaly closed terminals. You could have it wired to a normally closed part of the selinoid and when the 540 loses power though Estop, the coil of the selinoid de-energizes turning the coolant on. The Hal will allow the pin to either be hot or cold as a normal state. Change the Hal, and rewire the selinoid.

This of course is just a WAG as I haven't started playing yet with my own 540, but sure seems like the right answer from what I've read so far and know about selinoids.

If the information he first posted is correct, HAL won't have any effect on his E-stop loop. Yes he could have the HAL configured high or low (-xx or -xx-not) but if it is linked to parport pin 1, this controls g540 output 2 (Pos 6). With nothing hooked to terminal 6, can't be a player.

But I do agree that it is highly probable that the pump is wired through the NC contacts of the relay. To work as described (improperly) the HAL would need to be configure to be NC or high and when activated, Flood selected on Axis screen, transition open or low and the pump turns on. E-stop would do the same, drop the output low and close the relay's NC contacts.

But more info needed to be sure. Which cnc4pc board are you using and what do your HAL entries look like related to output to parport pin 17. Can you reference or post a pick of the cnc4pc wiring diagram?

The G540 has a DB25 and BOB built in no additional breakout board is needed.

"The G540 has a DB25 and BOB built in no additional breakout board is needed."

True, but it sounds like he using a simplified cnc4pc board to provide him DC relays, and switching a 110 or 220 Vac line to his pump.

123CNC,

SpeedCustom has one of these

Joey,

Thanks. If using the C15R1WD and the pump is wired as depicted here http://cnc4pc.com/Tech_Docs/C15R1WD.pdf (heavy/darker line is Line and lighter Neutral)

Then it shouldn't have the problem as described. If the pump's hot or Line is instead connected to NC (pos 1), then the wires need to be swapped and the HAL output reconfigured.

PS, Personally I wouldn't wire as they depicted, but rather as the terminal notation suggests. Run L to V-in (Pos 2) and the pump's hot leg to NO (Pos 3). This would allow you to use the other contacts (NC/PO 1) for alternate indication or use (what?.. be creative).

PSS, Rereading upthread, I realize I just said what MrWild had said earlier. Not bad for WAG, and apology for sounding like I was disagreeing. Was focused on the aforementioned HAL mode regardng pin 1. Hope to hear from SpeedCustom, to confirm how wild for MrWild.

Looking at my manual, something doesn't make sense with your explanation. Pin 1 on the 540 is "output 2."

G540 Terminal 10 is E-stop in my manual so that part looks correct.

I'm lost on your Pin 1 E-stop though. Unless Mariss says output 2 can also be an input, I don't think I'd use PP pin 1 for an e-stop. I need a monitor for my EMC computer before I can start playing with Hal files though.

First page of the manual says this, " ...While disabled, the motors freewheel, and the OUTPUT terminals "shut off." So you do have the coolant wired to the wrong terminals on yoiur selinoid. Change the wire hooked to "NC" over to "NO." Change the Hal file accordingly.

[SpeedsCustom]

I will make some changes and report back. Should I then maybe leave Pin 1 as unused, cause in theory I'm using the E-Stop for Terminal 10 on the 540 which does not link to Pin on the parallel cable.


I think I got this, will make changes. Thank you !
