12.2.4 Confirmation Connection

The XR315 offers two ways to provide confirmation feedback to a central controller: a 12V dc

output and isolated relay contacts. Confirmation tells the controller that the XR315 has indeed

powered up or that it is fully powered down. If the 12V dc output and the aux relay contacts are

not used for any other function, you will be free to choose whichever provides the best interface

for the application. However, if one of these outputs is used for another function you will have to

use the one that is available.

To use the 12V dc output for confirmation, connect "12V dc output" to the positive input of the

controller and "common" to ground. The output will be at 12V when the XR315 is powered up

and will be zero when the XR315 is powered down. Program 12V dc Output for "Confirm". Note

that the XR315 common terminal is shared between the inputs and the 12V dc output. If you need

relay contacts for confirmation and you are using the aux relay for another function you can

connect a small relay between the 12V dc output and common. The relay coil current must not be

more than 40mA, and you must connect a diode such as a 1N4148 or 1N4002 across the relay coil

(cathode to +12V dc) to suppress the back-EMF from the coil. If you need assistance with this

please contact our technical support department.

Connecting a 12 volt relay to the 12V dc output

To use the auxiliary relay contacts for confirmation, connect the contacts to the input of the

controller. The relay contacts will be closed when the XR315 is powered up and open when the

XR315 is powered down. The default for menu item "Aux Output" is "Confirm" so you do not

need to program this item unless you previously changed it. The contacts are rated for 30V dc at 1

amp.
