START-UP
Prior to operation, recheck electrical connections to be sure everything is in accordance with Figure 8
and Figure 9. If everything is in order, power may be applied. When power is turned on, the display will come
up with a program and version number, which will remain on the display for a few seconds. The display will then
change to a display of the fluoride value and an indication of the status of control relays. This is the main
operating display, and should look like the display below:
D1
XX.XX ppm
o
A
MAIN DISPLAY
The XX.XX portion will be numbers. The initial values could be almost anything, depending on whether
the sensor has been connected and what the condition of the sensor is. The values are not important at this
point. The display may indicate arrows to the left or right, but this should not be of concern until sample is
flowing. The next portion of the display indicates control relay status. The letter A refers to control relay A as
marked on the back of the monitor. An open square (
o
) indicates a deactivated relay while a solid square (
n
)
indicates an activated relay. More information on the control relays is provided in a later section of this manual.
Note that if the automatic calibration feature of this system is disabled, relay B status will also be displayed.
Beyond the main display, a series of alternate displays are available to the operator. These displays may be
selected by pressing the MODE key on the front panel. It is a good idea to step through the displays to become
familiar with each one. Many of these alternate displays serve as a starting point for programming functions
described later in this manual. The alternate display sequence is as follows:
