Network Connection Troubleshooting

Installation Procedure

• Install the myQA Accept software on the PC (for more details concerning the install wizard etc., see myQA Accept Instructions for Use). 
• Plug one end of an Ethernet cable to local network and the other end to one of the Ethernet port on the switch. 
• For each device (CCU-X, PC), plug one end of the Ethernet cable to the device, and the other end to one of the Ethernet port on the switch. 
• Connect the mains power cables to grounded mains power outlets. 
• Attach the Drive Control Cable to the DRIVE CONTROL connector of the water phantom. Lock the connectors by tightening the two screws.
• Plug the Drive Control Cable into the DRIVE CONTROL input of the front of the CCU-X. Take care not to force it into position. 
• Attach the remote control to the REMOTE CONTROL connector of the water phantom. 
• Switch on power of the computer and the monitor. Wait until Windows has finished booting. 
• Switch on power of the CCU-X. Wait until the device has finished booting 
• Use the Z movement key on the remote control to move the servo upwards. Now remove the transportation protection.

CAUTION: REMOVING TRANSPORT PROTECTION 
Do not remove transport protections when they are jammed between parts of the servo to avoid misalignment. Use the remote control to release the protection; do not move the axis manually.

Installing TMR Probe (Optional)

The TMR probe consists of a magnetostrictive sensor likewise used for the servo axis, combined with a magnetic float within an acrylic-damping pipe. 

When the TPR / TMR option has been purchased with the water phantom initially, the TMR probe is normally already mounted in the water phantom. 

However, if the TPR / TMR option is purchased later, follow installation procedure below:

• Ensure that the TMR probe with the float is inserted into the acrylic support tube. The label on the float must be oriented upwards. 
• Mount the support tube with the TMR probe in the water phantom. 

• Tighten the two fixation screws at the top of the TMR probe.

  

• Open the front housing of the water phantom connection box to get access to the back panel bar. 
• Connect the cable from the TMR probe to the TMR input socket.
• Close the connection box housing and ensure that the cables will not be squeezed when doing so. 

• Connect the phantom to the control unit and switch the power on.

  IMPORTANT NOTICE: CCU BOOT DELAY 
  When a TMR probe has been mounted into the water phantom, the CCU will recognize this automatically and read-out all sensor calibration data first. When connected for the first time, this process can take up to 10 minutes.

• Push the Zeroing button at the remote control to enter the corresponding sub-menu. 

  

• Verify that the float of the TMR probe is at its lowest position.

• Push the corresponding zero button to define the zero position of the TMR probe.
