7. While working from the User Interface Panel, perform the following
checks to ensure the analyzer temperature-control zone circuitry is
operating properly and the system pressures are set appropriately.
Record the temperature value for each zone and the system pressures
to use as a reference later while comparing the values.
Instructions for working from the “User Interface Panel”, refer to
Chapter 4 page 4-5.
If changes need to be made to any of the parameters settings, a pass-
word must be entered to allow the changes to be made. For details
about entering a password, refer to “Login/Set Passwords Screen” in
Chapter 4 page 4-30.

HOME ALARMS STATUS SETUP
a. Press the
STATUS
soft key to view the STATUS screen (Figure 3-6).
Check and record the current operating temperature readings.
This will help you determine if the signal wiring is properly termi-
nated and if all of the circuitry is operating properly.
Pay close attention to the temperatures of the (Oven) Heater (if
used), (Optical) Bench , and Cell (if used) readings. If these tem-
peratures do not increase, check the wiring for proper connec-
tions. If the wiring is properly connected, it may indicate a shorted
RTD for that temperature zone.
The Oven Heater temperature parameter is available only for applica-
tions with a heated Oven.
b. Check the pressure of the pilot valves – Manifold block and Zero
fluid (if used) pressure. Adjust the Actuator/Zero pressure regula-
tor to obtain a minimum pressure of 490 kPag (70 psig / 4.8 barg).
