Cayenne D / Chili D question,

[ffokazak]

Do you guys run either flash with proximity sensors when you use the substrate temperature control?

I mean if you set it to 230 degrees, the flash is controlled by the Prox sensor and not the control panel on the automatic? We can set the timer on the control panel of our press, but I don't see a way to have the flash turn off when the substrate temp reaches 230 degrees....

Is that how you run them when you use that feature?

Thanks!

I generally only use substrate temperature control.

when you set to say 230, once the substrate gets to 230, the flash turns off.

I set the 'timer' on the flash to 10 seconds

and initially the press 'flash' time to around 4-5 seconds.

once I see the flash turning off before the flash timer on the press control panel expires, I start lowering the time...

[ffokazak]

Thanks for that!

Is that the Chili or Cayenne?

Chili D

OK I've got to start poking around to see how to get the Cayenne D to work in this manner!

Thanks!

On our Cayenne D, you set the temp at the flash, not at the control panel. As far as flash time, its press controlled so we just bump it down in time as we go in the run often reaching 2 seconds or less in flash time pretty quick. Those Cayenne D's heat up quick.

I found the Cayenne D would make for much quicker flashes for medium to long runs but slower for the short runs, and the temperature sensor didn't operate like it did with the Red Chili D, couldn't be used as the cutoff reliably because it would delay the initial flash on the next garment, it wouldn't be consistent.

The temperature cutoff works with either the PLC setting or sensor setting, it just keeps reading the temp and cuts off the flash when set temp is reached.  The temp cutoff overrides the other settings whether at the press or on the flash (assuming flash time is long enough to reach cutoff, which it always should be...)

Essentially it's possible to set the flash for say 250 degrees, but the press is indexing more
rapidly then the flash can reach that temp, and the trigger for the next pallet can be missed because
the flash is still trying to get to temp from the first pallet? Is that correct?

[jvanick]

at least in the case of the red chili, the press signal 'resets' the plc in the flash on each index.

for those that care... the logic of the press and flash is actually such that the press is just 'holding' a switch on the flash for whatever time the flash timer is set to.

you can actually verify this yourself by hooking up a foot pedal to the switch, setting the flash to plc mode.  hold the foot pedal for 1 second, flash goes off in one second.. hold for for longer, the flash turns off when you release the pedal.

other than that it's really "stupid"... (inside the press there's just a relay that the press PLC is triggering).

Got it, that's good.

It would be super cool if the flash "held" the press until temp was reached, you could watch
the press heat up and start indexing faster and you wouldn't have to eff with the timing at all during a run.
Seems like it would be simple enough.

The press doesn't wait on temp (at least that I know how to do). I agree that would be a great feature. I will say for what ever its worth by the time you heat up the pallets and get the first few shirts loaded at a slower pace as the operator gets in his rhythm that our flashes are already flashing very quick. I am sure some operators are ready for 1000pcs per hour the second the first shirt goes on our guys seem to warm up to speed so first round or 2 is generally at a slower pace. So the flash is ready to rock by then.

[ffokazak]

Thanks Brandt, I will set it up like that!

[jvanick]

I asked about the waiting feature and was told that since there's no "return" signal designed into the flashes or plc that at the current time it's not possible.

When I built ours for our Calmat flashes I had it open the footpedal circuit while on, essentially stopping the press until temp is reached.
Only issue is cooling of the sensor itself to get an accurate reading, which remains to be done...

This is how I thought these worked....kinda seems like the whole point, set temp, fire up the press and print.  Press speeds up for you as temp is reached more quickly- nothing under flashed, nothing over, no running over to check the flash or indexing shirts back, etc.  That's what has attracted me to temp sensing flashes.  We don't burn shirts up too often but my crew has a hard time staying on top of the flash and reducing it as we go.  I've been having them use the control panel for this as it has 1/10th of a second bumps you can make.

I get that if you preheat or start out slower with the temp sensor units and work up to speed it shouldn't be a real issue though.

The SRoque flashes have a cooling mechanism on the sensors I hear, I think it's just a little compressed air.  It sounds like that's what caused most other iterations to fail or not work 100%, heating of the sensor during print runs.
