5.2 Manual (Reduced or Full) Speed Mode Circuit
5.2.1 Run Chain 1
Begins on the back plane with 24 VDC. Then:
- 24 VDC comes off the back plane AP80, through
plug X32 pin 5, then goes through plug XP/XS20
pin G to the Enabling Device in the Teach pendant.
- When the Enabling Device is pulled to the center
position, 24 VDC goes out of the teach pendant
back to XP/XS20 pin D.
- It then goes back to the Back Plane through X32
pin 2.
- From the Back Plane, the 24 VDC goes through
X35 pin 24 to the System board AP41 XP1 pin A12.
(This tells the computer that the enabling device
has been pulled to the center position.)
- 24 VDC will also go through a fuse FU3, (1.6 amps
on the back plane) out connector X35 pin 23 then
to customer connections XS3/XT3 pin A1.
