Functional Tests
To test the CCD Camera cooling function, proceed as follows:
1. Verify power at the TEC.
A. If no power available, go to Step 2.
B. If power present, replace cooler assembly.
2. 5VDC at output of Fluoro Functions PCB
A. If power is present, verify good connections between Fluoro Functions PCB and TEC.
B. Check power at input to Fluoro Function PCB. If power present, replace the Fluoro Functions PCB.
3. Verify presence of +12VDC at output of Power/Motor Relay PCB.
A. If no voltage present, verify voltage at the input of PS1. If voltage present, replace PS1.
B. If voltage present, verify cables and connectors between Power/Motor Relay PCB and Fluoro Function PCB.
