3-6 / Service CI-ControlWave XFC
3.4 GENERAL SERVICE NOTES
Certain questions or situations frequently arise when servicing the ControlWave XFC.
Some items of interest are provided in Sections 3.4.1 through 3.4.4.
3.4.1 Extent of Field Repairs
Field repairs to a ControlWave XFC are strictly limited to the replacement of complete
assemblies. Component replacement on a ControlWave XFC Printed Circuit Board (PCB)
constitutes tampering and will violate the warranty. Defective ControlWave XFC compo-
nents (Function Module or Multivariable Transducer (MVT) must be returned to Bristol
Babcock for authorized service.
3.4.2 Maintaining Backup Files
It is essential to maintain a backup disk of each application load file to guard against an
accidental loss of process configuration data. Without a backup record, it will be necessary
to reconfigure the entire application load; that can be a very time consuming procedure.
Always play it safe and keep backup copies of your operating system loads. A copy of the
application load can be loaded into ControlWave XFC FLASH memory and/or saved to a
PC’s Hard Drive as a ZIP file.
3.5 WINDIAG DIAGNOSTICS
Bristol’s WINDIAG program provides menu driven diagnostics that have been de-
signed to assist a technician or Process Engineer in troubleshooting the various
ControlWave XFC circuits. For more detailed descriptions of ControlWave XFC
Windows Diagnostics than those provided herein see Document D4041A – Chap-
ters 1 & 7C.
Bristol’s WINDIAG Software is a diagnostic tool used for testing ControlWave XFC elec-
tronics including, I/O circuitry, CPU memory, communications ports, etc., for proper per-
formance. The ControlWave XFC must be communicating with a PC equipped with the
WINDIAG program. CPU Board configuration switch SW1-8 must be set to the OFF
(Closed) position to enable diagnostics. Communication between the ControlWave XFC
(with/without application loaded) and the PC can be made via a Local or Network Port with
the following restrictions:
• CPU Board Switch SW1-8 must be OFF to run the WINDIAG program. Setting SW1-8
OFF will prevent the ‘Boot Project’ from running and will place the unit into diagnostic
mode.
• Any
ControlWave XFC communication port can be connected to the PC (Process Engi-
neer’s Interface) provided their port speeds and configuration match, e.g., baud rate,
parity, stop bits, protocol, etc. This can be accomplished via user defined Soft Switches.
• Setting CPU Board Switch SW1-3 OFF will force ports COM2 and COM3 to 9600 baud,
8-bits, no parity, 1 stop bit, BSAP/ControlWave Designer protocol operation.
• Setting CPU Switches SW1-3 and SW1-8 OFF prevents the ‘Boot Project’ from running,
places the unit into diagnostic mode and forces communication ports COM1, COM2 and
COM3 to operate at 9600 baud. COM1 can also be set to 9600 bps operation via user de-
fined Soft Switches.
