This procedure outlines how to use the mass flow controller using the ethernet control. This will eventually be integrated with Epics, making this procedure obsolete.

Step-by-step guide

Open the control panel on the web browser:
  1. Connect power and ethernet:
    1. Connect power cord to 120V outlet 2PK102E2 2 (on east side of penetration 20-12)
    2. Connect the 15-pin connector to the MFC device
    3. Connect ethernet from MFC to computer
      1. This can be patched through to 244 using the VQM channel in FKG20-30, port 12 on patch panel
      2. The status light should be blinking when connected
  2. Set up the ethernet port on your PC (Page 108-112 of manual). This should only have to be done once.
    1. From "Network and Sharing center", select the ethernet channel to open the LAN status
    2. Select properties
    3. Select Internet Protocol Version 4
    4. Select use IP address: 192.168.2.2 and subnet mask 255.255.255.0
    5. Select use the following DNS sever, but leave the entry empty
    6. Select OK to close the window
  3. Open a web browser and go to 192.168.2.155
To set the flow rate:
  1. Go to the "Plot" subpanel
  2. Switch from "Analog" to "Digital" (above Flow Setpoint)
  3. Enter a value between 0 and 1400 (for He gas)
  4. Press "Set"
To change the gas species:
  1. Go to the "Configuration" subpanel
  2. Enter the password "config" and press "Change settings"
  3. Go to the "Device" subpanel
  4. Change the "Selected Gas", press set
  5. Use the manual to learn how to add a new gas if your gas is not an option.
To monitor the flow rate setting:
  1. Connect a voltmeter to the pig tails labeled "FLOW SIGNAL"
  2. 0 V = stopped, 5V = Full scale flow rate
To use analog flow control:
  1. Connect a 5 volt variable voltage source to the pig tails labeled "FLOW SETPOINT"
  2. 0 V = stopped, 5V = Full scale flow rate
Approximate setpoints (in readout volts):
GasIP pressureFlow rate (est.)Input/Output voltage
Helium10 Torr8403 V
Helium5 Torr4201.5 V
Argon10 Torr2650.95 V
Hydrogen5 Torr5802.9 V
