SurgeX XR315 - Manual (Page 10)

Over-Ride Input Select “Contact Closure” if a relay or switch is used, or
“5-30V dc” if a DC voltage is used.
Over-Ride Func This selects the functioning of the over-ride. Select “Disable” if you do
not need an over-ride. If you want the over-ride to force the unit on
select “Force On”, and if you want the over-ride to force the unit off
select “Force Off”. If you are cascading two or more XR315s together
then select “Master” for the first unit in the chain, and “Pass-Thru” for
all other units in the chain except the last one.
Over-Ride Option This option allows a special delay to be selected for use only when
there is an over-ride. This can be useful, for example, to power-up
equipment faster than normal if there is an emergency and a PA is
required. If the special delay is required select “Special Delay”, or if
not, select “Use Main Delays”.
Over-Ride Delay This is the special delay (in seconds) for use only during an over-ride.
The previous menu item must have been set to enable this delay.
5.3 12V dc Output
The programmable 12V dc output provides a nominal 12 volts at up to 40mA of direct current
and is available at the rear of the unit. The 12V dc output can be used to provide confirmation to
a central controller, to control another power distribution product, to drive LEDs, or to provide
feedback to the previous XR315 in a cascaded chain. Please see the applications section for full
details on setting up an expanded system. There are three menu items to control the 12V dc
output: one to select the mode of operation and two to set the delay times. The two delay times
are only applicable when option A, B, or C is selected for 12V dc Output. There is additional
information on the 12V dc output in sections 3.2.3 and 3.2.4. If the DC output is not used it can
be left at any setting.
12V dc Output Select “Confirm” if you are using the DC output for confirmation or
to drive a relay. Options “A”, “B or “C” synchronize the operation of
the relay to the same internal trigger as the receptacles on the rear
panel of the XR315. Choose A, B, or C when the output is used to
control an “RT” type SurgeX. Select “LED” if you are driving LEDs.
(This causes the unit to flash the LEDs during power-up and power-
down.) Select “Cascade” only when setting up two or more XR315s
in cascade. All these options are covered in detail in the applications
section.
12V Delay On
Set the delay time in seconds for the 12V dc output activation. This
delay time begins with the same internal trigger as the receptacles on
the rear panel of the XR315.
12V Delay Off Set the delay time in seconds for the 12V dc output deactivation. This
delay time begins with the same internal trigger as the receptacles on
the rear panel of the XR315.
