XR315
Manual de usuario
______________________________________________________________________________
The XR315 in an expanded system can be controlled by the same inputs as a single unit system.
Figure 3 shows how the two units are wired together using the aux relay contacts. The aux relay
contacts on the XR315 (terminals 6 & 7) are connected to the contact closure inputs at the back of
the RT (terminals 1 & 2). The aux relay must be programmed accordingly. The Aux Output menu
item must be set to A, B or C. This synchronizes the aux relay to the internal trigger used to turn
on the receptacles on the rear panel of the XR315. The Aux Delay On and Aux Delay Off delay
times are then set to the desired turn-on and turn-off delays.
If an over-ride is used with an expanded system do not use the Special Delay.
Figure 4 shows how to configure an expanded system using the 12V dc output instead of the aux
relay to control external units. This option allows the aux relay to be used for confirmation but it
is then no longer possible to drive external LEDs from the 12V dc output. The programming and
delay timing set up follow the same concepts as for the aux relay which is explained above.
15.4 Ganged System
A ganged system consists of two or more XR315s connected together in such a way that they all
turn off and on together. Figure 5 shows how to connect and program each unit in a three-unit
system. If only two units are to be ganged together then ignore the middle unit in the diagram. If
more than three units are to be ganged together then keep the first and last units set up as shown,
add units in the middle and set them up and connect them in the same way as the middle unit in
the diagram.
The remote control inputs should be connected to the first unit, and the same control options are
available as for a single-unit system. If confirmation feedback is required for a central controller,
use the aux relay contacts on the last unit.
If the low and high voltage shutdown points are narrowed from their defaults of 90V and 150V
this should be done on the first unit only. The other units should be left set to 90V and 150V.The
two restore options should only be enabled (if required) on the first unit.
If an over-ride is required connect it to the first unit.
15.5 Cascaded System
A cascaded system consists of two or more XR315s connected together such that they turn on and
off one after another. Connecting a cascaded system together is a little more complicated than the
other types of system because there must be feedback from each unit to the previous unit as well
as control from each unit to the next unit. The 12V dc output (terminal 4) is used as the feedback
source and the over-ride input (terminal 3) is used as the feedback input. Figure 6 shows how to
connect and program each unit in a three-unit system. Note that terminals 5 and 6 are connected
together for all units except the last one. If only two units are to be cascaded together then ignore
the middle unit in the diagram. If more than three units are to be cascaded together then keep the
