ATI A15/66 Residual Sulfite Monitor

O&M Manual

Rev-W (8/10)

START-UP

Prior to operation, recheck electrical connections to be sure that everything is in accordance with

Figures 5 & 6 on pages 12 & 13. If everything is in order, power may be applied to the instrument. 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 sulfite concentration and an

indication of the status of control relays. This is the main operating display, and should look like the

display below:

D1 X.XXPPM A B MAIN DISPLAY

The X.XX portion will be numbers. The initial value could be almost anything, depending on

whether the sensor has been connected and the condition of the sensor. The value is not important at

this point. The next portion of the display indicates control relay status. The letters A and B refer to

control relay A and control relay B as marked on the back of the monitor. An open square () indicates a

deactivated relay while a solid square () indicates an activated relay. More information on the control

relays is provided in a later section of this manual.

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:

D2 X.XX PPM SO3 DISPLAY WITHOUT RELAY INDICATION

D3 TEMP: 20.0 C TEMPERATURE DISPLAY

D4 SA X.XXPPM O L RELAY A SETPOINT AND FUNCTION

D5 SB X.XXPPM O L RELAY B SETPOINT AND FUNCTION

D6 CLEANING OFF STATUS OF CLEANING FUNCTION
