Finally. Pilz was broken inside and made that "SAFETY GATE OPEN"

The fuse was blown. After connecting my X11 all messeges dissapeared. So we have problem out of KRC2. I think problem is with FAULT on PILZ.
-
One thing I have seen ad hoc: you have connected 88 to 89 and 106 to 107, so may be you have blown a fuse.
May be you should contact a person that's used to handle with schematics and electric equipment. jm2c.
Electric guy did that mistake. When I checked after him I found that mistake. Can you explain me where I can find that fuse?
Found this in PDF.

i don't see anything on 19
I made photos before realising that I connected it wrongly. Now everything is connected like on electric diagram. Errors are still the same...

this is how jumper plug for KRC2 looks like
you can change language to English so we can read the messages
Translation : error "EMERGENCY SHUTDOWN" "EXTERNAL EMERGENCY SHUTDOWN" "Illegal operating mode (?)" - messages in english - I have polish version.
Cant switch between operating modes
This is how my jumper looks like. I dont see 4 pins there maybe this is the problem.

This is how it looks like from my side. Photo was taken before changes. Now after 3 checks im 100% sure that all cables are correct. Major problem now is that I have error "EMERGENCY SHUTDOWN" "EXTERNAL EMERGENCY SHUTDOWN" "Illegal operating mode (?)"

This is how it looks like from KRC2 side

Ok I did X11 jumper according to this
From KRC2 "Side" left everything unchagned. I will attach photos in next post because I can have only 1at post.
-
Ok nothing happened. Still have mesage "Operator Safety / Gate Open". But I guess it won't work till I solve problem with red led on FAULT PILZ.

not by you maybe, but it is obviously affected by something... circuits age and fail due oxidation, vibration, transients and so on, memory gets corrupted, fails due wear etc. there are many possible reasons even though you did not observe event at the moment it happened.
the bottom line is unit is not operational and it needs service. if it needs to be reprogrammed, you need backup of the program, correct tools and follow product instructions. if you don't have them, you need to contact equipment manufacturer (integrator that built the unit). if you want to try to troubleshoot it yourself in hope of ruling out wiring problems, check circuits. if you don't know how to do that, get an electrician that does.
equipment already tells you that problem is related to user safety and not EStop so focus on right side of the circuit, which is User Safety.
for robot to be happy these channels would need to be closed. if PILZ does not close the circuits, you can insert test jumpers.
btw. contact numbers are weird so careful there and do it at own risk:
Tried to do this but nothing happened. Still have information about "Operator Safety / Gate Open". I made jumper between those 2 channels. Should I restart everything?

This is schematic diagram

Well, the first question is, how is your Operator Safe signal pair connected to the robot? On most KRC2s, it would be through the cabinet X11 connector, but you haven't provided any details about your exact KRC2 model, or your specific safety interface.
The first quick test would be to unplug the X11 cable from your external safeties, and temporarily plug in an X11 "shorting" jumper. If this solves the OpSafe signal issue, then we know the problem is in the wiring outside the KRC. If it doesn't, then the issue is internal to the KRC.
The other check would be to disconnect the X11 plug from the KRC, and perform continuity checks on the pins for the OpSafe signals. From the KRC, your safety devices should appear electrically as simple relay contacts. OpSafe has two channels, A and B, and your safety wiring should connect one of the X11 Test A outputs to the OpSafe-A input, and one of the Test B outputs to the OpSafe-B input (only when the safety gates/barriers/scanners are in a safe condition, of course).
Exactly, KRC2 is connected to PILZ through X11. Wiring diagram
Could you explain me how can I exactly make shorting jumper?
-
Because according to their instructions :
- Insert the chip card containing the new user program into the device.
I have no idea how can I get this program and what is that program

Robot was working correctly 1 month ago. But KRC2 was shaking - cabinet was cleaned and after 2-3 weeks I tested it but batteries were completly dead. When I turned off robot it lost some informations becuase It shut down so fast. Batteries were replaced and after 2 days during test that message appeared. I can normally weld in T2 mode but I have to hold switches on KCP.
According to PILZ led error I've read that
https://www.pilz.com/en-INT/su…solutions/articles/181032
But nothing was done with PILZ and safety. I have no idea why it turned red.
-
I have 2 barriers and they are working correctly. The robotic station was equipped with a door that had been removed. I checked this place but there are no wires anywhere

Hi everyone!
Can't solve problem with message0 "Operator Safety / Gate Open". Can't move robot in AUT mode. IN T1/T2 it moves without any problem. I know that something connected with safety is not letting it work. I've already read previous topics my $MACHINE.DAT is ok
Additionaly I have red LED on PILZ on "FAULT" position. I suppose this may be connected.
Does anyone have any suggestions? -
Thanks a lot! . Today I have checked that all and robot is welding and moving without any errors.
-
Yeah actually I was changing some welding points and tried to run just that one weld and make it there. Can I run it like this?
-
I uploaded what I saw while working with KUKA. Didn't change antything in INI line. It's still on program start.
The moment when it occurs is -> robot is moving to point to make weld then it starts to weld and then stops (error shows).
