Changing Gas (Mass Flow Devices)
To change the gas that the device measures:
.
Select the device from the Devices module list to open
its tab.
2.
Click the drop-down menu under Selected Gas and
scroll down to the gas that you are flowing.
3.
Click the desired gas. The device is now set to measure
that gas.
!
Note: If you do not see the gas you are
flowing on the list, please contact Alicat
before proceeding to verify if your unit
is compatible with the desired gas.
▲
Caution: Do not flow gases that are not
on the gas list. Doing so voids the device
warranty and may cause permanent damage
to your flow device. Contact Alicat with
any questions about supported gases.
Setpoints (Controllers)
See figure 13
The setpoint field allows you to change the setpoint on
a controller. The type of setpoint is displayed under the
selected gas in the device tab.
• Change the setpoint by entering the desired
value in the setpoint text box, then click Apply.
• Reset the setpoint to zero by clicking Zero.
• Change the setpoint type by going into the
device’s settings. Under the Controller tab,
change the selected setpoint type.
!
Note: If your device’s setpoint source
is set to analog, the setpoint entry is
hidden. The Setpoint source is changed
to Serial/Front-Panel through the device’s
settings under the Controller tab.
Totalizer Batch (Mass Flow and Liquid Controllers)
Controllers with an enabled totalizer have the option to
dispense gas in batches of a desired volume. To do so,
perform the following:
. Reset the setpoint to zero.
2.
Enter the desired amount in the Totalizer Batch field
and click Apply.
3. Enter a valid setpoint and click Apply.
Once the desired amount of flow has passed through the
device, the valve shuts, but the setpoint remains the same.
The valve will remain shut until either the batch size is zero,
or Reset Totalizer is clicked. Clicking Reset Totalizer with
a defined setpoint starts a new batch.
The engineering units of the batch are determined by the
Total Mass Unit box in the Measurements tab of the
device settings.
!
Note: If the totalizer is not enabled,
please refer to your device’s manual
(alicat.com/manuals) on how to enable it.
