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
“
ACTIVE ” 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 stabilized (2–3 hours) and reached normal operating
temperature.
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).
The Oven and the rest of the sample system will reach normal oper-
ating temperature in approximately 2 hours, however (application-
specific) analyzers may take up to another hour to stabilize.
To minimize the time it takes for the entire sample system to warm
up to normal operating temperature, be sure to close the doors after
performing the checks that require them to be open.
