FANUC ARC MATE 100i ,RJ2 controller .
cannot reset servo 003 dead-man switch alarm.i off teach pendent and can reset fault.press cycle start button in cabinet cycle start normally.
after on teach pendent press dead-man switches and press reset button again come servo 003 alarm dead-man switch release.
please help fix this alarm

I imagine you have a bad Teach Pendant, it might be time to get a replacement. Or if you have another robot, you could swap them to see if that fixes it.... then spend the money on a new one.

but teach pendent other function is ok.
two dead-man switch in pendent.I press these.but not fix error -

please help fix this alarmMy first guess is bad TP/TP cable. Make sure BOTH are good. After that, there are 3 relays on the mcc on the B size controller that work with the TP deadman. Not sure where they are on the i. If you have another working i cabinet see if you can find any moving as you press deadman in and out, then see if they are moving on the non-working cabinet.

how to find dead-man relay
thanks for yours answers.

There is a control cabinet right behind your robot and you have a remote unit extended with a cable. On both, there is a cable entry for the Teach Pendant. First of all, if you are wearing a remote boom of your cable, replace it and put it in the cab behind the robot. If there is no change, you need to test the Teach Pendant and your cable on another system.
If the cable is defective, it must be repaired. If the pendant is defective, the "smd M7" diode is probably on the electronic card inside. You can repair someone who understands electronic repair. The duty of this diode is to protect the card in case of a short circuit in the cable.
The same protection robot is also present on the cable entry card and must be checked. "AML1994" you can see in the lower right corner when you open the door of the cabin behind the relay robot my friend said. You can even check the fuse plug on the same relay board. Remember that the "M7" diode change is the last digit.
According to the Pendant version, you can also see another protection diode. I wish that if the defects of my robots can be solved so much ... -
first I thanks for your answer.
OK.I checking it -
thank you.
"byrol" correct.2 diode are broken.
correction : not m7.it is a7
i checked my connectivity.its ok.
after check internal circuit of teach pendent.i see 2 diodes broken.
whats the reason damaged this diode? -
The duty of this diode is to prevent the short circuit voltage from damaging the Pendant board when any short circuit occurs in your cable. Some kind of short circuit protection. There is probably a short circuit on your cable. If you check with a gauge, even if it looks normal, the cable is short-circuited when there is a small movement. As a result, the board in the control cabinet of the short-circuit diodes burns out.
-
you say cabinet control board have same protection diode.they are broken? i doesn't checked cabinet.
-
I did not say it exists from the same diodes on the controller side. "If the diodes in the pendant are burnt, it is probably faulty on your cable." I say.
-
ok.thank you "byrol".
after replace diode and say my problem condition.thank you.
-
thank you "byrol" and others.
my problem is OK.
teach pendent A7 diode is broken.
teach pendent wire have small damage.
after repair problem is OK.i not press some buttons in pendent.but pendent give the these button signal to the cabinet.i think this problem is noises.because wire shield are damaged.
again thank all of you help for me.
-
i correct my problem.
thank you for help to me.
your solution are good -
Hi Byrol and AML1994,
Thanks for sharing the info. I'm having the same issue that while I keep pressing the deadman switch, the robot gives me the error that the switch is not pressed. I'm using SpotTool software, with C305 pendant. When I use a more advanced pendant like C370, which obviously does not work on RJ2 and gives me SRDY OFF (TP), surprisingly the deadman switch works and the robot throws the alarm of deadman released, only when I actually release the switch. This makes me think that the cable and the internal circuitry of RJ2 is working fine in terms of detecting the status of the DM Switch. Therefore, the issue should be the C305 pendant. I searched a lot for the smd diode M7 or A7, but couldn't find it. Any help would be much appreciated.

You tested the cable and you wrote that the cable is intact. As a rule, in cases where the cable is short-circuited, there may be a malfunction of the electronic card in the control, for your information. I'll still try to answer the question I asked. The short circuit protections on the card you sent your picture to are not made with a diode, but with the smd transistors I marked. Although the fact that they are three-legged does not necessarily mean that they will be transistors, they can also be three-legged smd diodes. You need to check their strength with a measuring instrument. According to the version and year of the controller, there may be changes in the design of the electronic card, but the basic logic remains the same. All of the smd's that you see on the card in this way and that carry the same code are usually put in for short circuit protection. There is even protection for the on-off or Emergency stop or Shift buttons that remain pressed.

Many thanks for your comments. I will go through these to see if I can find any inconsistencies.
