7 Configuration and Use
Operation Mode
This is the mode used during normal operation of the instrument. It can be accessed from the
Main Menu, and is the usual mode entered at power-up. The available displays are
dependent upon the features and options fitted and the way in which it has been configured.
WARNING:
DURING NORMAL USE, THE USER MUST NOT REMOVE THE CONTROLLER FROM ITS
HOUSING OR HAVE UNRESTRICTED ACCESS TO THE REAR TERMINALS, AS THIS WOULD
PROVIDE POTENTIAL CONTACT WITH HAZARDOUS LIVE PARTS.
CAUTION:
Set all Configuration parameters as required before starting normal operations. It is
the responsibility of the installing engineer to ensure that the configuration is safe
for the intended application.
Base, Trend & Profile Operating Screens
The Base screen is the usual screen displayed during operation. It provides “at a glance”
information about the process. The Profile Operating screen shows similar information when
using profiles. Trend View is a graphical representation of recent process conditions. Its
scale adjusts automatically for the best resolution for the visible data.
Note:
Trend data is not retained at power down or the Sample Interval is changed.
