2-26 / Installation & Operation CI-ControlWave XFC
For a unit containing 2MB of SRAM, a worst-case current draw of 42uA allows a battery
life of approximately 7142 hours.
Jumper JP1 on the front of the CPU Board (see Figure 2-8) must be installed to enable the
battery. For maximum shelf life, the battery may be isolated from the circuit by removing
Jumper JP1. JP1’s suitcase jumper can be stored on either of its pins.
CPU Boards are shipped with the Lithium backup battery installed. Removal of the backup
battery requires the removal of the Front/Display Cover and the CPU Board. To remove the
backup battery (on the rear side of the CPU Board, pry up the Battery Securing Tab on the
Coin-cell Battery Socket and then remove the battery using a pair of tweezers or needle-
nose pliers. Install the replacement battery. Note: This step will not be required until units
have been in operation for an extended period of time (normally many years) as the battery
life is approximately 7142 hours of backup service. (Power is only drawn from the battery
when the unit looses power).
NOTE:
If the Lithium backup battery is disconnected or removed when power is off the
contents of SRAM (on the CPU Board) will not be retained. Once a Lithium
backup battery has been removed, don’t install a replacement battery for at least
one minute unless SW1-5 on the CPU Board has been set OFF.
2.4 OPERATIONAL DETAILS
ControlWave XFC electronic flow computers are shipped from the factory with firmware
that allows the unit to be configured in conjunction with an IEC 61131, application
program. This section provides information as follows:
- Steps required to download the application load and place the unit into ‘Run’ mode.
- Steps required to download system firmware.
- Operation of the CPU Board Switch (SW1) mode functions
- Soft Switch Configurations and Communication Ports
-
Operational details on the use of the BBI WINDIAG program for fault isolation are
provided in Chapter 3.
2.4.1 Downloading the Application Load
Any ControlWave XFC must have a configured application load before it can be placed into
operation. For units not shipped with the ‘Standard Load,’ this will require connection of the
ControlWave XFC to a PC running Windows NT (4.0 or higher), Windows 2000 or Windows
XP Professional and equipped with ControlWave Designer software & OpenBSI software.
Configuration of the application load must be performed by an individual familiar with the
various programming tools. The following software user documentation is referenced:
Getting Started with ControlWave Designer Manual - D5085
ControlWave Designer Reference Manual - D5088
Open BSI Utilities Manual - D5081
Web_BSI Manual - D5087
An application load download can be initiated, i.e., from ControlWave Designer, or from the
OpenBSI 1131 Downloader for ControlWave XFC Nodes.
