OAK LOW AIR ALARM

Post by Titleiiarms »

Another stupid question Im sure but Ive read and searched and cant find an answer. Sorry..


Oak with PlC add pin 18 input . Low air input , high when has air, low when I take off the hose. Monitor led for input 18, is green when air on, red when air off. NO ALARMS. I ran a simple gcode program ( multi drill ) for several minutes and while running I pulled the air off and still no mention of LOW AIR. The input turned red. I inverted the LOW AIR input but makes no differerence and LOW AIR wont display. I DID see it a couple times about a week ago and my logs indicate it DID work. Not sure what makes that come up.. MY HAAS goes nuts when I take the AIR off :) THANKS !

If you search your PLC program for "AirPressureOk_I", you might find the following block:

Code: Select all

IF !AirPressureOk_I && (ToolUnclampOut_O || M80_SV || M81_SV)
  THEN FaultMsg_W = LOW_AIR_FAULT_C, SET OtherFault_M
... which says that low air pressure is a Fault, only when you are trying to unclamp a tool or move the carousel in or out.

If you want low air to trigger a fault immediately and unconditionally, just change the logic condition to something like:

Code: Select all

IF !AirPressureOk_I
  THEN FaultMsg_W = LOW_AIR_FAULT_C, SET OtherFault_M
