SurgeX XR315 - Manual (Page 9)

5 Programming
The XR315 is a very versatile product and has 16 menu items that control its operation. Some
menu items allow predetermined options to be selected and others allow time delays or voltage
limits to be adjusted. All adjustments are made via the front panel and are achieved by turning
the two screwdriver-accessible rotary encoders labeled Select and Adjust. Turning Select steps
through the menu (shown on the first line of the display), and turning Adjust allows each menu
item to be changed (shown on the second line of the display). The accessory kit contains a
screwdriver suitable for making adjustments.
To enter the programming mode, first turn Select one click clockwise. The display will then tell
you to press the power button. This puts you into the programming mode. All the options, delay
times and voltage adjustments are set using this mode. When you have completed the set-up turn
Select counter-clockwise until the display tells you to press the power button again. Doing so
saves the new set-up information in non-volatile memory and puts you back into normal
operation.
The instructions and notes that follow are in the same order as the actual menu items.
5.1 Power Control
The following menu item must be set before the XR315 can be used in a system. This determines
the type of control input: DC voltage, contact closure or switch. Please see section 3.2.1 for
details.
Up & Down Inputs Select the option as per section 3.2.1
5.2 Over-Ride Control
The XR315 has an optional over-ride and there are four menu items that control this function. If
you do not require an over-ride, you can skip the next four menu items since units are shipped
with this function disabled. The over-ride can be used for such purposes as fire safety over-ride,
and can be set to either force the unit on or force it off when an over-ride signal occurs. The
over-ride input is also used for feedback when two or more XR315s are cascaded together. This
is covered in the applications section.
