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:
1. Turn off the power supply and disconnect the AC power source. Allow five (5)
minutes to elapse to dissipate stored energy before making connections or
resetting switches. Refer to
“Configuring for Remote Programming, Sensing,
and Monitoring” on page 48 for instructions for resetting switches or making J3
connections.
2. Connect one side of the external relay to pin 15 (+15Vdc Auxiliary Output) on
connector J3. Connect the other side of the relay to pin 14 (TTL Shutdown
Input). Also connect pin 2 (Shutdown Return) to pin 6 (Auxiliary Supply
Ground). See
Figure 3.19 through Figure 3.22 .
3. Set internal switch SW1-8 to select the desired circuit logic as set out in
Table 3.4 .
