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 all banks are powered up
and will be zero when all banks are powered down. Program 12V dc Output for “Confirm”. Note
that the XQ515 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 all banks are powered up and open when all
banks are 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.
4 Quick Start
This section is intended to allow users with a simple straightforward system incorporating a
single XQ515 to get up and running with the minimum of effort. If this is not the case then skip
this section and go directly to the section on detailed programming (section 5). If you are going
to follow the quick start instructions, you only need to perform the following steps since the unit
has been shipped with default settings suitable for basic operation.
