a. Press the
STATUS
soft key to view the STATUS screen (Figure 3-5).
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).
c. Check the Aspirator Pressure (gas applications only) from the
STATUS screen; the pressure should be adjusted to the value
stated on the system drawings, or enough to see a flow on the
Flow Indicator (or meter), if used, or to achieve an acceptable re-
sponse time. Typically, a good response time is less than 30 seconds
to T90 when the sample system is clean and operating at peak ef-
ficiency – response time may vary due to Sample Line length. The
response is application-specific and will vary, depending on the
sample system.
