8 Troubleshooting
Hand Controller Calibration Failed
• e luer connections on the hand controller may not be rmly connected to
the control panel. Rotate the control panel upwards for a better view of the
luer connections.
• If the hand controller becomes disconnected during a case or needs to
be replaced, connect a new hand controller and recalibrate by pressing
CALIBRATE HC on the control panel.
• Make sure to press OK on the control panel to start calibration before
pressing the contrast (C) button on the hand controller.
• Make sure the tubing for the hand controller is not kinked.
• e contrast (C) button on the hand controller must be pressed within
4seconds of starting the hand controller calibration. Calibration can fail if
too much time elapses.
• Insucient pressure may have been applied to the contrast (C) button
during calibration.
• Press OK and then press CALIBRATE HC on the bottom of the control panel
screen to retry the calibration procedure.
Pressure Limit Exceeded
• e stopcock may be closed.
• e pressure, ow, or rise time parameters may be congured incorrectly.
If the Pressure Limit message appears, it means the congured pressure limit
was nearly reached. e CVi system automatically adjusts to keep injection
pressure beneath the congured limit by reducing or stopping the ow rate.
Standby!
e Standby button on the right side of the control panel has been pressed.
1. Press the Standby button again.
2. Press OK.
Manifold Valve Open
e manifold valve normally opens during an injection, which may cause this
message to appear during normal operation. If this message appears while an
injection is not in progress, check the following items:
• e manifold is not fully secured in the manifold valve sensor.
• Push the Standby button to pause the CVi system to allow the manifold
valve to return to its home position.
• Continued pressure from the syringe may be keeping the valve open. A
short purge may cause the manifold valve to return to its home position.
• e white slide clamp above the contrast sensor may be closed.
• e manifold may need to be replaced.
Important
If patient bodily uids are observed in the patient tubing, or if the system
displays both the Manifold Valve Open and Syringe Valve Open indicators along
with any error message, replace the syringe when prompted at the end of the
case.
