Analyzer Start-up
1. Turn on power source.
2. Open main process shut-off valve. Adjust sample pressure between 20 and 50 psig.
Dry Down Period
Allow a minimum of 24 hours for the analyzer to dry down and stabilize. System
alarms are normal during this period. When dry down is complete, cell frequency
will be stable and the recorded data will have leveled off.
Status LEDs and Alarms
There are three LEDs used for local indication of the system status. The green LED
indicates power is supplied to the system. The red LED is used to reflect the status
of the concentration, data valid, and system alarms. In the event of a concentration
alarm, the red LED will be on. The yellow LED reflects sample flow status. On
indicates sample gas is being measured, off indicates dry reference gas. In the event
of a system alarm, the red LED will signal the source of the problem. The red LED
will flash on for one second and off for one second with the number of flashes as
indicated in Table 3.1. Once a flash sequence has completed, the LED will remain
off for five seconds. At the end of the pause period, the sequence will be repeated.
If there are multiple system alarms then the highest priority alarm will be indicated
until it clears. The alarms are listed in order of priority with the higher priority
alarm having the fewest flashes.
