3-26 | Model 933 UV Analyzer
IMPORTANT
Performing analyzer start-up and verification procedures requires us-
ing the System 200 Configurator Software. Familiarize yourself with
the software before working on the analyzer. See Chapter 4 for details
on how to navigate through the software.
To power up the analyzer and verify it is operating properly:
1. Apply AC power to the analyzer.
Establish communication between the analyzer and the Configurator
Software. (See “Starting the Configurator Software and Establishing
Communication Between the Analyzer and Computer” in Chapter 4.)
2. Perform the following checks to ensure the analyzer starts up properly
and is ready to be commissioned into operation.
If you cannot verify the checks in this step, refer to “Start-Up Diagnos-
tic Checklist” in this chapter or the “Troubleshooting and Diagnostics”
section in Chapter 6 for information on how to correct alarms or per-
sistent problems. Resolve any problems before proceeding to the next
start-up stage.
a. Verify the operation of the status relays (Customer I/O board, Fig-
ure 3-10):
• The Alarm Invalid Relay (or Zero-CAL Problem Relay)
and the two Concentration Alarm Relays will be in the de-
energized state. Observe the green LED D406 (Alarm Invalid/
Zero-CAL Problem Relay) and the two red LEDs D407 (Con-
centration 1 Relay) and D408 (Concentration 2 Relay). These
LEDs should be ON to indicate normal operation.
• The state of the Fault Status Relay and the Warning Status
Relay depends on the current status of the analyzer. Typically,
both relays will be de-energized upon initial power-up because
the Column Block and Optical Bench temperatures have not
yet reached their respective setpoints, and are generating a
“Fault Column Temp Lo” and “Warning Bench Temp” alarm,
respectively. Verify the alarms on the Status tab (Figure 3-14).
These green LEDs D404 (Fault Relay) and D405 (Warning Re-
lay) will be OFF in this case.
