Troubleshooting, Symptom Problem

Troubleshooting

NOTE: The system contains no user-serviceable parts. If there is a problem with your system, it must be returned to Pelco for servicing.

Symptom: Degrading video quality

Occasionally, image quality may degrade.

1.Perform a manual FFC. After manually performing this process, the camera restarts the frequency clock and resets the baseline temperature (refer to Flat Field Correction on page 15).

2.If the problem persists, perform the troubleshooting steps in Symptom: No video or poor video.

Symptom: System does not operate

1.Check the system input voltage.

2.The TI2500 Series thermal imager is protected by a resettable overcurrent protective device located in the transformer module. Whenever a fault condition happens in the system causing excessive current flow through the protective device, a change occurs that will prevent current flow. The protective device remains in this state as long as power is applied and the system fault continues. The protective device resets itself after power has been removed for a few minutes, and then operates normally when the system fault has been repaired.

3.Check the system power and video BNC connections.

4.Check that a fuse has not blown.

DANGER: Failure to disconnect power to the camera before replacing a fuse could result in accidental injury or death.

The system is fuse-protected against overvoltage. A blown fuse is an indication that either the circuit has been overloaded or that a short has occurred somewhere in the circuit. A wiring problem may be placing too much load on the circuit if a fuse blows after plugging in or turning on the camera. Before replacing the fuse it is important to identify what has caused the failure.

Prior to changing a fuse, turn off the electrical circuit or completely disconnect the camera. Make certain that no dangerous conditions exist before restoring power. Replace the fuse with a 2 A blade fuse (Bussmann® ATM-2 or equivalent). Never use anything other than a fuse of proper rating.

Symptom: No video or poor video

1.Check the system power and video BNC connections.

2.Check all coaxial BNC connectors from the camera to the monitor.

3.Make sure the controller is set for the correct camera-to-monitor viewing combination; for example, Camera 1 to Monitor 1. Refer to the controller manual for information.

4.Check for normal load termination of 75 ohms. When looping through VCRs or multiplexers, make sure the signal is terminated at the end device. Typical termination symptoms and problems are listed below.

Table E. Termination Symptoms and Problems

Symptom	Problem

Extremely bright video	No termination or high resistance

Over contrast or contrast level of monitor	Double termination (37.5 ohms)
needs to be increased to maximum for a
good video image

Symptom: Unable to view activity through glass

When the camera is pointed at a window, it cannot detect activity behind the glass. This is a limitation of thermal imaging technology. Consider repositioning the camera.
