MAINTENANCE

Cleaning

• Start cleaning after turning off the detector.
  Test

• Carry out a regular test before use to ensure stable and normal operation of the detector. If the problem occurs, contact the manufacturer.

• Please perform tests based on items listed in the checklist below.

TROUBLESHOOTING

If you encounter problems when using the detector, use the guide provided in the corresponding section to solve the problem. If the problem persists, please contact the manufacturer.

properly.

•    Disconnect and reconnect the main cable.

When the detector is suddenly turned off

during the use

| •    Check if the main cable is connected properly.
When the LEDs of /          parts on

the control box blink in orange

| •    Check the status of the power cable connection of the Control Box.

•    Check if the Control Box is properly connected to the X-ray generator or detector.

When the detector is not connected to the PC| •    Check if the power is on. If the power is on, check the following items.

•    Check if they are connected in accordance with the instructions in the manual. Try connecting again.

•    Go to   ****> [DXD] > [Connection & File Save] in and run a [Ping Test] to check the connection. Alternatively, open a browser window and enter an IP in the address bar to check if a page is loaded properly.

•    Check if the PC’s network IP uses the same IP as the detector.

•    In some cases, a connection issue may occur especially because of the firewall rules that block all ICMP packets coming from Win 8 OS. Please refer to the Troubleshooting Firewall Issues.

When there is a problem with the status of the acquired image| •    Make sure that there is no foreign matter on the surface of the detector.

•    If an image is acquired immediately after turning on the detector, a poor image may be acquired due to an unstable panel. Open the [Calibration] menu in and acquire a couple of Dark Images first, or wait for a while and try again.

•    If the image is still unstable, run a [Calibration] and apply the result before proceeding.

acquiring images in the [Validation] after creating the [Calibration] result file in the Calibration menu, an abnormal image may be acquired. Check the issues below and follow the guide.

1 When some areas appear in black or light bleeding occurs in the acquired image

– Go to the [Calibration] menu > [BPM Analysis] on the left bottom corner and check if [Rows] and [Columns], [Class] 5 ~ [Class] 8 have more than dozens of values. If so, follow the steps below to run a new [Calibration] and acquire [Validation] images.

1. Adjust the X-ray generator’s position so that the detector is within the X-ray irradiation range before running a [Calibration].

2. Keep the distance at least 120 cm between the detector and the X-ray generator tube.

3. If the distance cannot be more than 120 cm in Step 2), change the detector settings as follows before proceeding with the [Calibration].  Go to > [Calibration SW] and enter a value 0.05-0.1 higher than the existing value for [     ] and [Save].Go to > [Calibration SW] and enter a value 1.5-2 times greater than the existing value for [      ] and [Save].

NOTE

•    Due to the heel effect of the X-ray generator, if the distance is short, less X-ray irradiation may be applied to the edge of the detector. This difference makes it necessary to adjust the [Gain] and [Offset] values. The [Gain] adjustment is a required process, but the [Offset] adjustment may be skipped depending on the situation.4) Go to the [Calibration] menu and acquire Dark Image and Bright Image to run a [Calibration]. If the [BPM Analysis] result is not improved, repeat Step 3).

2  When some areas appear in black in the form of the straight or curved line

–  Check if the problematic area is within the X-Ray irradiation range.

–  Check if foreign matters or other objects are on the detector.

3 When white or black pixels appear in the image

–  Run a [Calibration] again to create a new Calibration result, and, with the result, acquire [Validation] images.

–  It the problem persists even after the new Calibration, set the pixel as a Bad Pixel in the [User BPM] and go to [History] > [Open] on the top right corner to load the newly created calibration result and perform a [Validation] again.

PROGRAM NOT LAUNCHED DUE TO ACCESS PRIVILEGE ISSUES

1.  When the program is not launched with the following pop-up after going to”Launching Program”> “IP Address Check and Ping Test”> “Save Location Check”> “Apply”, check the following items.

2 Right-click the launching icon of and select [Properties].

3 In the [Properties] window, enter into the [Compatibility] tab and select the Run this program as an administrator checkbox under the [Privilege Level].
