power back on. If Fuse F1 still blows then change out the
analog module. If F1 fuse does not blow, turn off power and
check wiring on connector for any shorts to ground.
Unplug all MAS connectors from the
back of the machine at the quick disconnects. Insure you
reconnect them to the proper location to avoid start up
problems. Replace fuse and turn power on. If fuse still blows
go to 5.2. If fuse does not blow then check for a short in one
of the MAS and repair as needed.
F6 ties into a lot of
components and is the
most difficult to
troubleshoot. The
process of elimination
will be used so please
follow each step
before moving on.
To isolate which leg is causing the problem pull the following
relays from the board. R1, R2, R3, R6, K6, K9 AND K5. Turn on
power and see if F6 fuse blows. If F6
fuse blows then go to 8.2 If F6 fuse does not blow then go to
8.3
Mag Starter, Green
Start Push Button,
Buzzer in the P.C
control Cabinet, Non
conductive Key Switch,
Safety Switch, or
the stepper motor for
the upper tooling is
shorted.
To isolate the components to find the cause of the short
please follow closely. Replace all relays from step 8.1.1 Next
remove wires T-63, T-60, T-86, T-62, T-67& T-61 Turn on power
and if F6 fuse blows then reconnect all the wires back and
Change out mag starter. If fuse does not blow then
reconnect T-15 and turn power back on. If fuse F6 blows,
change out green start push button. If the fuse does not
blow, reconnect wire T-62. If F6 Fuse blows, disconnect all
MAS plugs at back of machine and reconnect them one at a
time with turning the power on and off after each one is
connected to find the one causing the outage. If the F6 does
not blow after wire T-62 is connected, reconnect wire T-67. If
fuse F6 blows, change out the conductive key switch. If F6
Fuse does not blow, reconnect wire T-86. If F6 fuse blows,
change out the buzzer inside the P.C console. If F6 fuse does
not blow, Reconnect wires T-60 and T-63. If F6 Fuse blows,
change out the stepper Driver Board.
Pull Relays R1, R2, R3, K5, K6, K9. Insert one really at a time
and turn on power to see if the fuse F6 blows. Until you find
the relay or path causing the short. Then Change out they
relay.
Check to ensure that wire T-3 is connected to the grounding
strap on the safety switch.
Pull fuse F-10 and turn on power. If F9 fuse blows, change
out P.C Board or replace the 6 volt rectifier on the board.
