ATI Q46D Dissolved Oxygen System Part 6 - Configuration
33
O&M Manual
Rev-N (4/21)
For ultrapure water applications, set this value to 0.00. For sea water
applications, set this value to 53.00.
Timer Funcs Enables the Autocleaner Logic on Relays D, E, and F. When enabled,
these auxiliary relays control the remote autocleaner enclosure. The
autocleaner enclosure provides automatic sensor cleaning using a highly
effective air-blast system (Q-Blast) that is self-contained in the AC
enclosure. When enabled the D, E, and F relay settings are not
disdplayed in the CONFIG or CNTR menus. This can also be used to
control a customer supplied external air delivery source.
Com Mode Sets digital communication mode of analyzer. Optional digital
communication card must be plugged into the power supply slot for this
function to work. Press ENTER to initiate user entry mode, and the
entire value will flash. Use the UP arrow key to modify the desired value;
selections include 1-None, 2- P-DP for Profibus DP, 3 – Modbus, 4 –
Ethernet IP. Press ENTER to store the new value.
Com Address Sets bus address for digital communication mode of analyzer. Optional
digital communication card must be plugged into the power supply slot
for this function to work.
Press ENTER to initiate user entry mode, and the entire value will flash.
Use the UP arrow key to modify the desired value. Range is 1-125.
Press ENTER to store the new value.
Iout#1 Mode This function sets analog output #1 to either track PPM or mg/L oxygen
(default), % Saturation, or enables the PID controller to operate on the
oxygen input in either PPM, mg/L, or % Saturation. Press ENTER to
initiate user entry mode, and the entire value will flash. Use the UP
arrow key to modify the desired value; selections include 1- for oxygen
tracking or 2-PID for oxygen PID control. Press ENTER to store the new
value.
*Iout#2 Mode This function sets analog output #2 for either temperature (default) or
oxygen. Press ENTER to initiate user entry mode, and the entire value
will flash. Use the UP arrow key to modify the desired value; selections
include 1-C/F for temperature, or 2-ppm for oxygen, or 3-% Saturation.
Press ENTER to store the new value.
*Iout#3 Mode OPTIONAL. This function sets analog output #3 for either temperature
(default) or D.O. Press ENTER to initiate user entry mode, and the
entire value will flash. Use the UP arrow key to modify the desired value;
selections include 1-C/F for temperature or 2-ppm for oxygen. Press
ENTER to store the new value.
*Rly A Mode Relay A can be used in three different ways: as a setpoint control, as a
fail alarm, or as a HI-LO alarm band. The three settings for Rly A Mode
are CON, FAIL and AL.
The CON setting enables normal control operation for Relay A, with
settings for setpoint, hysteresis, delay and phasing appearing in the
CONFIG menu automatically. See Figure 21 - Control Relay Example,
Hysteresis & Phase Options for further details.
