PROBLEM: Error Code “E93/E94" No data transfer to and from console.  

START 

Make sure that the eproms are plugged into the correct socket and  orientated. 

Refer to EPROM replacement procedure.  

Correct? 

No 

Place EPROM in correct socket. 

Yes 

Check crane supply voltage for console in central unit at connection board X: 33 (ground) and X1:30 

(+12V). Make sure external and internal power supply is correct. Refer to Section  4. 

Refer to system wiring diagram. 

Correct? 

No 

Replace main board and reset pressure channel. Refer to 

system wiring diagram and transducer replacement 

procedure . 

  Bad Data Transfer Between Console & Central Unit 

 

 

 

Yes
