PART TWO
Technical Section
The SureFlow monitor is ready to use after being properly installed. The pressure sensor
is factory calibrated prior to shipping, and should not need adjustment. The Digital
Interface Module (DIM) is programmed with a default configuration that can be easily
modified to fit your application.
The
Technical section is separated into five parts that cover all aspects of the unit. Each
section is written as independently as possible to minimize flipping back and forth
through the manual for an answer.
The
Software Programming section explains the programming keys on the DIM. In
addition, the programming sequence is described, which is the same regardless of the
menu item being changed. At the end of this section is an example of how to program the
DIM.
The
Menu and Menu Item section lists all of the software items available to program and
change. The items are grouped by menu which means all calibration items are in one
menu, alarm items in another, etc. The menu items and all related information is listed in
table format and includes programming name, description of menu of item, range of
programmable values, and how the unit shipped from the factory (default values).
The
Calibration section describes the required technique to compare the pressure sensor
reading to a thermal anemometer, and how to adjust the zero and span to obtain an
accurate calibration. This section also describes how to zero a flow station.
The
Maintenance and Repair Parts section covers all routine maintenance of equipment,
along with a list of repair parts.
The
Troubleshooting section is split into two areas: Mechanical operation of the unit and
system performance. Many external variables will affect how the unit functions so it is
critical to first determine if the unit is having mechanical problems - i.e., no display on
unit, remote alarms don’t function, etc. If problems still exist, look for performance
problems (i.e., d
oesn’t seem to read correctly, display fluctuates, etc.). The first step is to
determine that the system is mechanically operating correctly, followed by modifying the
configuration to eliminate the performance problems.
