Installation and Start-Up | 3-31
Purged Analyzers (Hazardous Locations):
Insert the key into the Purge Bypass Switch and switch it to the
“BYPASS” position (follow company policy).
[Special Conditions for Safe Use]
The analyzer may only be energized by using the Purge Bypass
Switch with permission of the works manager or his proxy. The per-
mission may only be given when it is made sure that during the time
the system is energized by using this switch an explosive atmosphere
is not present or when the necessary protective measures against
explosion hazard have been taken (“hot permit”).
The analyzer enclosure may not be opened when an explosive atmo-
sphere is present.
Close the Analyzer fuse.
Apply main AC power to the analyzer by closing the explosion-proof
power-disconnect switch.
2. Immediately following power-up, the Host Controller board software
version number will appear on the top line of the User Interface and
the message “Reset in Progress” will appear on the bottom line.
If the “Reset in Progress” message does not appear within approxi-
mately 2 seconds, simultaneously press • and Ent.
If the “Reset in Progress” message still does not appear, take all neces-
sary safety precautions to power down the analyzer, open all of the
fuses for the temperature zone circuitry, and check the AC wiring to
ensure it is properly connected.
After powering down the analyzer, wait 5 minutes to allow the high-
voltage capacitors in the source-lamp power supply to discharge.
Review the Analyzer (AC) Power Connections drawing(s) and check
the wiring terminations from the power supply source to the analyzer.
Take all necessary safety precautions and power up the analyzer
(Step 1). Check the User Interface again to see if the message appears.
If it does, continue with the next step.
