Other Functions
Reading through the programming section is a good way to understand all the functions and
options available in the XQ515. Most of the functions are associated with main operation
outlined in this section above. However, there are some other independent functions that can be
selected:
The front panel button can be programmed to be operational, non-operational or operate after a
one-second delay. Choosing the last setting prevents accidental power-up or power-down. See
section 5.5 for more details.
The XQ515 has built-in voltage limits that will cause the unit to power down if the line voltage is
outside these limits. The low limit can be set from 90V to 110V and the high limit can be set
from 130V to 150V. See section 5.6 for more details.
The XQ515 has internal self-test circuitry that constantly monitors the operation of the unit and
displays the word “Good” or “Fail” on the front panel. The unit can be programmed to shut down
in the unlikely event that the self-test should fail. See section 5.7 for more details.
There are two “Restore” options. The first option allows the unit to restore to a power-on state
after loss of AC power or out-of-range AC voltage. The second option allows the unit to restore
to a power-on state after being forced off by an over-ride. See section 5.8 for more details.

Single Unit System
Most of the information necessary to install and set up a single unit system can be found in
sections 3.2 and 6.1. Figure 1 shows a single unit system controlled by momentary switches at
three different locations, and figure 2 shows a single unit controlled by a central controller.
6.3
Expanded System
A basic expanded system consists of an XQ515 in combination with a remote turn-on SurgeX
such as the SX1120-RT or the SX20-NE/RT. Such a system provides a total of four banks and 40
Amps total load capacity. The auxiliary relay inside the XQ515 is normally used to control the
second unit although the 12V dc output can also be used for this purpose. The only difference in
these remote control configurations is that, when the aux relay is used to control a second unit, it
cannot be used for confirmation feedback to a central controller, and when the 12V dc output is
used for control it cannot be used to drive LEDs.
If more current capability is required then additional SurgeX RT products can be connected to
the second unit. Connect pins 6 & 7 of the second unit to pins 1 & 2 of the third unit, and so on.
It is possible to configure a five bank expanded system by using both the aux relay and the 12V
dc output to simultaneously control two separate pieces of equipment or two racks of equipment.
In this case, refer to both figures 3, 4 & 5 and follow the instructions below.
