Operating information
automatically change these fields to the maximum value possible. If
you are not using a control equation, touch
Next
to continue. If you
would like to enter pH or conductivity parameters using a control
equation, follow the steps below before touching the
Next
button.
• Slide the on/off button for “Control Equation” and “Hysteresis”
to the “On” position.
• Touch the field next to “Control Equation” to enter the setpoints
for pH or conductivity, and the action that should be taken
(either
Pause
or
Stop
).
• Touch the field next to “Hysteresis” to enter the pH or
conductivity value that should be reached, and the length of
time that value should be held, before the pump resumes.
Touch
Next
.
4. On the screen that appears, the following will be displayed at the
top of the screen: remaining amount of fluid to be delivered, current
pH or conductivity reading, and the total amount of fluid to deliver.
The time remaining will be visible in the center of the screen. If you
have entered a control equation, the equation will be shown at the
bottom of the screen. If a control equation has not been entered,
“Control Equation Disabled” will be shown at the bottom of the
screen, instead.
6.6.3 Adjusting temperature
The Touchscreen Console allows you to monitor the temperature of the
solution while it is mixing. On the Touchscreen Console Home screen,
the Temperature module shows the current temperature in degrees
Celsius (°C) as read by the system.
To adjust the temperature of the imPULSE S.U.M. using the
Temperature module on the Touchscreen Console, your system must
have an integrated temperature control unit (TCU) set up. Follow the
instructions below to adjust the S.U.M. temperature.
1. Before adjusting the temperature, ensure that the probe you are
using has been correctly inserted into the thermowell.
2. On the Touchscreen Console Home screen, touch the top of
the
Temperature
module. Touch
Select Active Sensor
on the
Temperature Settings screen.
3. The following screen will prompt the you to select a temperature
sensor to use. You may choose either
Temp1
or
Temp2
. After
selecting a sensor, touch
Done
. Touch
Close
to return to the
Touchscreen Console Home screen.
