FlexTest IIm Controller Connections 194
The interlock connectors require jumpers under the following conditions:
• If you do not use the external hydraulic/program interlocks on any of the D-
15S connectors (J3A Sta 1, J3B Sta 2, J3C Sta 3, and J3D Sta 4). Use an
external jumper plug (PN 052-750-501) on each connector not used.
• If you use the system digital I/O as a stand-alone unit. That is, if you do not
connect the System Digital I/O Module to a 497.xx Chassis, you must use an
external jumper plug (PN 050-774-701) on the J5 497 Intlk connector.
This shows how to connect an external switch or set of relay contacts to one of
