2) ADJUST THE SETPOINT FOR EACH RELAY
The setpoint for each relay is set by the front panel buttons marked SP1, SP2, SP3 and
SP4. When a front panel button is pressed and held down, the associated setpoint is direct-
ly changed. The direction of change will be either up or down, as indicated by the UP and
DOWN indicator LEDs. After the indicator LED lights up there is a 0.5 second delay before
any change occurs. To reverse the direction of change, release the button and then press
down again. As there are no menus or sub-menus to navigate, the programming and setup
is quick and easy.
Setpoints are indicated on the bar display by an ON segment if the bar is below the set-
point and with an OFF segment if the bar display is above the setpoint.

To comply with the latest safety requirements, the tri-color bargraph is designed like a traffic
light, to display either red, orange or green, but only one color at a time. When the bar reaches a
selected color change point, the entire bar will change to the color designated for that zone. This
eliminates any ambiguity as to the signal status, especially just after transitioning to a new zone.
However, if two or more setpoints with differently specified colors are positioned at the same
set point value, the color specified for the set point with the highest identifying number will be
displayed. When set points are set to the same value, the SP4 color overrides the SP3 color, the
SP3 color overrides the SP2 color, and the SP2 color overrides the SP1 color.
STEP A ENTER COLOR SET MODE
Hold down ALL four setpoint buttons (SP1, SP2, SP3 and SP4) and apply power to the
meter. The meter will light up in the Color Set Mode. Release all the setpoint buttons.
STEP B SELECT COLOR FOR BAR ABOVE SETPOINT 1
Hold down the SP1 button. The color of the bar segments below SP1 will cycle between red,
green and orange. Release the SP1 button when the bar is the required color. Now
Whenever the bar is above the SP1 level it will be this color. When the bar is below the SP1
level it will always be red.
STEP C SELECT COLOR FOR BAR ABOVE SETPOINT 2
Hold down the SP2 button. The color of the bar segments below SP2 will cycle between red,
green and orange. Release the SP2 button when the bar is the required color. Now
whenever the bar is above the SP2 level it will be this color.
STEP D SELECT COLOR FOR BAR ABOVE SETPOINT 3
Hold down the SP3 button. The color of the bar segments below SP3 will cycle between red,
green and orange. Release the SP3 button when the bar is the required color. Now
whenever the bar is above the SP3 level it will be this color.
STEP E SELECT COLOR FOR BAR ABOVE SETPOINT 4
Hold down the SP4 button. The color of the bar segments below SP4 will cycle between red,
green and orange. Release the SP4 button when the bar is the required color. Now
whenever the bar is above the SP4 level it will be this color.
STEP F EXIT COLOR SET MODE
Turn off the power to the meter for 5 seconds and then reapply the power. The bargraph will now work with the programmed colors.
