Cary 50 Spectrophotometer Hardware Manual
No green light indicating that the Cary 50 is powered
The Cary 50 is powered directly from the computer power supply. A
green power indicator light on the front of the Cary 50 indicates
when the instrument is powered.
Problem
The power indicator on the Cary 50 does not light when the computer
is switched on.
Solution
Check the connection of the main instrument cable connecting the
computer to the Cary 50.
If the power indicator on the front of the Cary 50 is still not on, check
the connection of the computer power supply connector to the Cary
50 card inside the computer. Instructions for the connection of the
power supply connector are listed in the installation guide supplied
with your Cary 50 (and in the ‘Hard disk power supply connection
section’ on Page 31 if you need to use a Y connector).
Start button replaced with Connect button
Problem
I have a ‘Connect’ button instead of a ‘Start’ button.
Solution
Only one Cary WinUV at a time can communicate with the
instrument. If you want to change to another application, you can
click the ‘Connect’ button to bring this application online.
When you turn on the computer, the Cary 50 calibration program
initializes the Cary 50. If you start another application, for example,
Scan, before this initialization has finished, the application’s ‘Start’
button will be unavailable. Wait for the status line at the bottom of
the application to display ‘Idle’ and the ‘Start’ button will become
active.
