on wire 25 to energize the coil of the YV3-12 Directional
Valve. LED 9 will be lit.

IMPORTANT!
Each of the “Safety Input,” “Safety Output” and “Safety Power”
Modules has a specific address that must be set on the DIP
Switches on the side of each module! (Illustration 80) When
replacing any of these Safety Modules, refer to the Electrical
Schematic and make sure the “Address” DIP Switches are set
correctly for that module. If they are not set correctly, a “System
Fault” will occur and the module will not work!
