3-28 | IPS-4 Dual Bench (UV / IR) Analyzer
After the start-up screen, the system defaults to the HOME screen
which allows you to view the current status of up to nine factory-con-
figured parameters. These parameters are displayed on the left side
of this screen. The right side of this screen displays the current op-
erational status of the analyzer. Descriptions of these parameters and
states are described under “HOME Menu Screen” and “System Status
Messages (HOME Screen),” in Chapter 4.
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.
After powering down the analyzer, wait 5 minutes to allow the high-
voltage capacitors to discharge.
Review the Interconnect Wiring drawing (part of the analyzer Final
“As-Built” drawings package) 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
System Leak Check,” later in this chapter.
