3-30 | IPS-4 Dual Bench (UV / IR) Analyzer
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).
