An external relay, whether normally open or normally closed, may be used to activate the
Shutdown circuit. Either positive or negative logic may be used.
To activate the Shutdown function using an external relay:

2. Connect one side of the external relay to pin 15 (+5 VDC Auxiliary Output) on connector
J3. Connect the other side of the relay to J3-pin 14 (Remote Shutdown Input). Also
connect pin 2 (Shutdown Return) to pin 6 (Status Indicator Return). See Figure 4–13
through Figure 4–16.
3. Set rear panel DIP switch S1 to select the desired circuit logic as defined in the following
table.
