Heidelberg SM74 T Error S-EAK 1 F3FF

Dear All

I have recently encountered a T Error on my Heidelberg SM74-4+LX 1999. After running a diagnostics test it indicates it as error S-EAK 1 F3FF. Please find attached pictures.
Please let me know how i could resolve this issue as i can't seem to find an origin.

 

Hi sir
Will be a good idea to Test the device IWH.eath leake Monitor Module.
Since this device control and monitor all Eart leaKE, electronic board,Flat cables,cables to push buttons, limit switch, and motor of the printing press with a DC voltages[120. Raise in efficiency of the press...!!
In normal operation the green led is On.
If there occurs and earth leake, it will be indicated by a Red led diode after about 20 seconds.
The button LT has to be pressed at The IWH. Red light goes out.
The operation of the press will Not affected.The yellow malfunction light at the contro console indicate(f60=> paper run not possible)
However the module can be tested in other way.
Disconnect B1+B2 andpushing the check button PT about 2o seconds= green ligth diode goes out ,the red light Led goes on.
Press the LT button afterwards for operation.

Hi

Can you please advise what i can do in regard to the T Error & the error displayed " Fault Detected During Operation".

I am in the process of checking the earth leakage but my major concern is the T error.

Please advise.
