SECTION 6: TROUBLESHOOTING

This section provides useful information and solutions for some troubleshooting scenarios. If you have an issue

that you are unable to rectify using this section, please contact Andor Technical Support for further advice.

6.1  Camerabuzzerdoesnotsoundonstart-up

1. Thecamerabuzzershouldbeaudiblemomentarilywhenthecameraisswitchedon.

2. Ifthisdoesnotoccur,ensurethatpowerisconnectedtothecameraandtheOn/OswitchissettoOn

6.2 CameraisnotrecognizedbyPC

1. Ensure the camera is switched on

2. Check the Camera to PC connection. For Camera Link models, check that the cable is connected

between the CL1 connector position and the PCIe card in the PC. (For 10-tap variants, check that the

CL2 cable is connected). For USB 3.0 models, check that USB 3.0 cable is connected between the

camera and the USB 3.0 slot on the PC.

3. Check that the frame grabber card and drivers have been correctly installed (see Sections 3.4 and

3.5)

6.3  Buzzersoundscontinuously

This indicates that an “over temperature” condition has occurred within the camera. Follow the instructions

below to rectify this situation:

1. Powerthecameraoandallowittocooldown

2. For air-cooled models, ensure fan vents are not obstructed

For water-cooled models, ensure that water coolant supply is connected and that chiller/re-circulator

is operational

3. Checkthecameraisoperatingwithinthespeciedenvironmentalconditions(seeAppendix A)

6.4 Fan not operating as expected

• To protect the internal electronics, the fan defaults to full speed if the camera heat-sink temperature

exceeds 50°C.

NOTE: The fan will continue to run even if the user has switched it o via software, until the correct heat-

sink temperature has been reached.

6.5 Camera does not cool to the required temperature

1. Check that the operating ambient temperature is within allowable limits (see Appendix A) when

cooling the sensor to 0°C.

2. Checkthatthecameraventsarenotblockedandhavesucientclearancetoallowairow.

3. Check that the fan is switched on (or for water cooled models, the coolant system is operating

correctly).
