1. Make sure the individual relays are properly connected to the output terminals. 2. The WRS-2224 Scanner will usually be in NORMAL mode. If left in PROGRAM mode, it will revert to NORMAL mode after 2 minutes. If the NORMAL MODE indicator LED is OFF, press its select button to exit the PROGRAM mode.

Another method of interconnecting load centers/relay panels is to use the Douglas WNX-2624 Network Node. With the WNX-2624 Node, you can network the WRS-2224 Programmable Relay Scanner with a non- polarized data signal to other WRS-2224 Relay Scanners. Up to twenty-four WRS-2224/WNX-2624 scanner/node combinations can exist within a self-configured system.
