INITIAL POWER UP
Allow adequate time (approximately 60 minutes) for the heaters to begin
operation and for the OCX 8800 to reach normal operating temperature on
power up. Normal operating temperature for the O
2
cell is 736°C. Normal
operating temperature for the combustibles cell is 300°C. The normal sample
line temperature is 170°C. During this time the eductor air solenoid will remain
closed so no sample is pulled through the analyzer. When the OCX reaches
operating temperature the solenoid will energize, eductor air will begin to flow,
and the unit will begin normal operation.
