3. Check that the large inductor (L1) located in the middle of the power supply circuit board
has not broken loose:
• If the L1 inductor has broken loose, replace the power supply board (04S-0676-01 or
04S-0676-02.)
• If the L1 inductor has not broken loose, replace the fan. Refer to ”Removing and
Replacing the Cooling Fans” on page 5-10.
Resolving Communications Problems
If communication fails or cannot be established between the F6300 and the F6150:
1. Check the Ethernet cable.
2. Verify that the CPU circuit board LEDs (D1 & D2) are blinking.
3. If the communication cable is functioning and no conflicts are found, replace either the CPU
circuit board, Analog I/O circuit board, or the Communications circuit board. Refer to
Chapter 5 ”Field Replacement Procedures” when replacing these boards.
Error Types
Three types of errors can occur while using the F6000 Instrument:
• ”Hardware Errors”
• ”Source Errors” on page 4-13
• ”System Errors” on page 4-14
Hardware Errors
Hardware error messages display on the VFD on the Instrument front panel. They are often the
first sign that something is not functioning properly in the Instrument.
NOTE Hardware errors must be resolved before further testing can proceed. Check and ensure that
the IP address is set correctly on the F6150 and F6300.
Table 4.4 describes hardware errors and possible solutions.
