The red light on my LIFA control unit is on

Is there an overexposure detected? There is an anode current limiter inside the control unit; an error is reported when the current of the anode of the image intensifier is above a certain threshold preset in the factory. A high anode current normally indicates that a high instantaneous light level is entering the camera. Please make sure there is no light illuminating the camera and press the ‘Reset’ button. The photocathode of an image intensifier becomes less sensitive with increased total light dose. The anode current limiter protects against the highest instantaneous light doses. Note that there is no automated protection against somewhat lower light levels.

Is there a LED failure reported? If the control unit detects a LED failure, the LIFA will also report an error. Is the LED cable connected correctly to the LED? If so, the LED could be broken.

When using LI-FLIM through Active-X there is a watchdog function which can be used inside your scripts. It is a timer that can help to protect your image intensifier when running long series of automated measurements. To prevent entering an error mode one needs to reset the watchdog timer or set it to zero before it is zero, to turn it off.

Is there a high temperature and humidity in the operating room? Sometimes this can give a false positive overexposure.
