5.2.8 Run Chain 2 - Manual Stop Circuit
Run Chain 2 begins on back plane with 0 VDC.
- 0 VDC goes out X32 pin 8.
- In XS/XP20 pin “F”.
- Out to the teach pendant’s enabling device.
When the enabling device is pulled to the center position:
- 0 VDC will go out XS/XP20 pin “E”.
- In to the back plane X32 pin 3.
- 0 VDC goes out X35 pin 8.
- To the customer connection XS3/XT3 terminal B1.
This is where the customer can wire into the Manual
Stop circuitry as was done for Run Chain 1. If this is
NOT used, a jumper is placed between XS3/XT3
terminals B1 and B2.
