14 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).

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.

14.1 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

14.2 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.

Over-Ride Input

Over-Ride Func

XR315

Select the option as per section 3.2.1

Select "Contact Closure" if a relay or switch is used, or

"5-30V dc" if a DC voltage is used.

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.
