8 Operation and Configuration Menus
This section contains information on all of the controller’s modes and the configuration
menus.
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/options fitted and the way in which it has been configured.
The Base screen is the usual screen displayed durin g operation. It provides “at a glance”
information about the process. The Profile Status screen shows similar information when
using profiles.
Subsequent screens allow the display and selection/adjustment* of the setpoints. From
display configuration, a selection of other parameter screens can be made available for
operator selection/adjustment*. These include: profile control; cascade open/close;
auto/manual control; setpoint ramp rate; setpoint source; control enable; clear latched
outputs; data recording & status trend views. Optional operator mode screens are marked
◘
in the screen lists.
Some screens will persist until the user navigates away, others will ‘time-out’ back to the
base screen.
* If required, all Operation Mode parameters can be made read only (see Display
Configuration on page 59Error! Bookmark not defined.). Otherwise parameters such as
setpoints can be adjusted within their configured limits.
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.
Navigating and Adjusting Values in Operator Mode
Press R to move forward or L to move backwards through the available screens.
When a displayed value can be adjusted, use D or U to change its value.
The next/previous screen follows the last parameter. If no further changes are needed,
hold down R or L for >1sec to skip straight to the next/previous screen accepting
ALL values shown.
In Trend Views, pressing D or U moves the cursor line back and forward through the
last 240 data points.
