TROUBLESHOOTING

9.2.6 MMI fails to power 
on 

PLC not powered  
 
 
 
 
 
 
PLC ok but MMI to PLC 
connections  
 
MMI cable connection ok 
but still not powered on  
 
 

Check fuse F4 if blown 
then change & check 
power on indication on 
PLC if not rectify by the 
help of help of wiring 
diagram, if wiring ok then 
PLC faulty contact AMF 
Reece for new & replace 
Check MMI cable 
connection 
 
 
Chance of MMI faulty or 
PLC to MMI connection 
Port is faulty contact AMF 
Reece for new & replace 

9.2.7 DC motor for jig 
movement fails to 
functional 

DC motor card in cabinet 
is not powered  
 
 
 
 
Necessary command 
signals for function is 
missing  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
DC card faulty  
 
 
 

Check Fuse F5 if Blown 
then Change if still not 
functional then check 24 
V DC power at input 
terminals, rectify by the 
help of wiring diagram 
 
Go to MMI System Check 
Menu – Output test- DC 
drive speed 1 screen & 
give command for test.  
While test command is 
on check 24 V DC 
between P24 sleeve wire 
terminal & Y31,Y33 
sleeve wire terminals. If 
no voltage rectify by 
wiring diagram, if signal 
is ok then check DC 
voltage at M+ & M- 
sleeve terminals turn the 
speed potentiometer on 
card to anticlockwise DC 
voltage at M+ & M- 
should increase. if it 
increases check the DC 
motor power cable & 
rectify by wiring diagram.
