Using the EF-Series Unit
2-28 Rev 2/01
2.8 TROUBLESHOOTING AND REPAIR
Troubleshooting and repair procedures are designed to help you identify and fix problems with the
Main Electronics Board and communications cards. Contact your Fisher Representative before you
attempt to remove a suspected faulty board or card for repair or replacement. To troubleshoot
communications cards, refer to Section 3.
The following items may be needed for troubleshooting:
♦ IBM-compatible personal computer.
♦ ROCLINK Configuration Software.
The ROCLINK Configuration Software runs on the personal computer and is required for a majority of
the troubleshooting performed on the EF-Series unit. Refer to the ROCLINK Configuration Software
User Manual for additional information.
2.8.1 Backup Procedure Before Removing Power
Use the following backup procedure when removing or adding components. This procedure preserves
the current flow computer configuration and log data held in RAM.
Before removing power to the EF-Series unit for repairs, troubleshooting, or upgrades, perform this
backup procedure.
CAUTION
When working on units located in a hazardous area (explosive gases may be
present), make sure the area is in a non-hazardous state before performing
these procedures.
CAUTION
To avoid circuit damage when working inside the unit, use appropriate
electrostatic discharge precautions, such as wearing a grounded wrist strap.
1.
Launch the ROCLINK Configuration Software.
2.
Ensure that the configuration is saved in flash memory by performing a Write to Internal
Config Memory (use the ROC Flags screen accessed from the ROC menu). This saves all
configuration settings, including the current states of the ROC Flags and calibration values.
3.
If you will be replacing the flash chip, save the current configuration data to disk by using the
Save function in the File menu. This action saves the configuration to an .fcf file (you can
specify your own file name and path if desired).
4.
Select Collect Data from the ROC menu. Ensure the All box is checked and click OK. This
action saves event logs (.evt), alarm logs (.alm), report data (.det), hourly logs (.pdb), and daily
(.day) logs (you can specify your own file name and path if desired).
