WARNING
If these screens do not appear, check the AC wiring to ensure it is
properly connected.
To check the AC wiring, take all necessary safety precautions to power
down the analyzer and open the Main AC Power and DC Power
fuses.
Wait 2 minutes to allow the high-voltage capacitors to discharge.
Review the Customer Connections drawing and check the wiring
terminations from the main AC power supply source to the analyzer.
Take all necessary safety precautions and reapply power to the ana-
lyzer by closing the Main AC Power and DC Power fuses. Check the
User Interface Panel again to see if these screens appear. If so, continue
with the next step.
4. Perform a leak (pressure) check to ensure there are no leaks in the sys-
tem, then return to this procedure and complete the remaining start-
up and verification tests.
To perform the leak check, follow the procedure under “Sample Sys-
tem Leak Check,” later in this chapter.
5. After the leak check has been performed and has passed, close the
Bench Heater fuse and Oven Heater fuse (if Oven/Sample System
Enclosure is heated) to apply power to the Measuring Cell and Oven
Heater temperature-control zone circuitry. Ensure that the sample
system door has been closed and latched.
Watch the purge controller until the indicators turn green (left) and
black (right). Install the key in the bypass valve and place it in the AC-
TIVE position. Remove the bypass and enclosure keys and keep them
in a safe place.
No alarms will be displayed on the HOME screen or entered into the
Alarm Log until AFTER the system has left the Not Ready state
for the first time after power-up, which occurs after the entire sample
system has reached normal operating temperature and has stabilized
(2–3 hours).
6. While performing the remaining start-up tests, close the analyzer
doors to allow the sample system to warm up to normal operating
temperature (necessary only if Oven/Sample System Enclosure is
heated).
