5.6 Out-of-Range AC Voltage Shut Down
The XR315 has built-in line voltage monitoring and out-of-range shut down. The default limits
are 90V at the low end and 150V at the high end, and shut down begins if the line voltage
remains outside the set limits for 1 second or more. These limits are adjusted by using two menu
items, with the low limit adjustable from 90V to 110V and the high limit adjustable from 130V
to 150V. If the unit has shut down due to an out-of-range line voltage and the line voltage
subsequently returns to normal, power up will only resume if the Power Fail Restore option
(section 5.8) has been set to “Enable”.
Low-V Shut Down Set the low voltage shut down limit from 90V to 110V
High-V Shut Down Set the high voltage shut down limit from 130V to 150V
5.7 Restore Functions
There are two menu items which, when enabled, allow the XR315 to restore the original “on”
condition after shut-down caused either by loss of AC power (or out-of-range AC) or by an over-
ride. When these options are disabled, the XR315 will not power up when the condition that
caused the shut down goes away. The restore functions cannot be used in conjunction with
applied voltage or latching type remote control inputs.
Pwr Fail Restore Select “Enable” if you want the XR315 to power up after a power
failure or out-of-range AC condition and the XR315 was powered up
when this condition occurred. Select “Disable” if you don’t want this
function. Factory Defaults: v1.0: Disabled, v1.1: Enabled.
Override Restore Select “Enable” if you want the XR315 to power up again after being
forced off by an over-ride. Select “Disable” if you don’t want this
function.
6 Applications
The XR315 can be used in four types of configuration: a single unit providing eight outlets; an
expanded system where the XR315 controls remote turn-on SurgeX products; a ganged system
where two or more XR315s are connected together such that they all turn on and off at the same
time; a cascaded system where two or more XR315s are connected together such that the units
turn on sequentially from one XR315 to the next XR315. Each configuration is covered
separately in its own section, but first there are some general points which apply to all types of
installation.
6.1 General Points
Section 3.2 provides detailed information about the remote control connections. If you have not
already done so, please read section 3.2 before continuing. The information in section 6.1 applies
to all types of installations and you should also read this section before continuing further.
