AN-T80020 Diagnostics Procedure
Issue 12 Feb 11 AN-T80020 59
SFIU_RELAY_IMON_TST
0x63mn
Modules:8442
Subcode: mn:
m = quadrant (0 to 3) + current
monitor (0 or 4 for #1 or 2),
n = output (0 to 5) This tests the current flowing in a relay on a speed output FTA during
switching tests. Replace and return the FTA when possible.
Action:Slice fault
SFIU_RELAY_IMON_ERR
0x64mn
Modules:8442
Subcode: mn:
m = quadrant (0 to 3)
n = output (0 to 5) Current is measured in a relay coil when it should be de-energised or
vice versa on the Speed Output FTA. Replace and return the FTA
when possible.
Note that on firmware release 3.5 this error occurs with no SOFTA
present even if marked as absent in the INI; in this instance a firmware
upgrade is recommended.
Action:Slice fault
OFIU_HWOVC_FAULT
0x640n
Modules:8472
Subcode: n = channel (0 to F) Detects a faulty overcurrent (OVC) detector. An OVC has been
detected but it did not lead to a de-energised load, and the OVC alarm
can’t be reset. Return the module for repair.
Action:Slice fault
OFIU_OVP_FAULT
0x65nn
Modules:Output (not
8472,8442,8480)
Subcode:nn = output channel
8471: 0x00 to 0x1F (1 to 32)
Others: 0x00 to 0x27 (1 to 40) Detects a faulty overvoltage (OVP) detector. If the fault is persistent,
return the module for repair.
This error code does not apply to 8448 and 8449 channels that are
configured as inputs.
Action:Slice fault
8442: see below.
SFIU_RELAY_DRIVE_TST
0x65mn
Modules:8442
Subcode: mn = quadrant (0 to 3),
output (0 to 5) A relay command or diagnostic failed a test for latent faults. This could
indicate a module fault or a speed output FTA fault. Replace the
module; if the fault appears on the new module, the fault is on the
speed output FTA. Action:Slice fault
OFIU_LINK_ERR
0x66nn
Modules:Output (not 8472,
8442,8480)
Subcode:nn = output channel
8471: 0x00 to 0x1F (1 to 32)
Others: 0x00 to 0x27 (1 to 40) Detects serious errors in field interface comms link such as faulty
optocouplers or a dead output group. Also detects channel address
errors in host interface RAM. Return the module for repair.
Action:Slice OFFLINE
8442: see below.
SFIU_RELAY_DRIVE_ERR
0x66mn
Modules: 8442
Subcode: mn = quadrant (0 to 3),
output (0 to 5) A relay command or diagnostic failed on the Speed Output FTA.
Replace the module; if the fault appears on the new module, the fault is
on the speed output FTA.
Note that on firmware release 3.5 this error occurs with no SOFTA
present even if marked as absent in the INI; in this instance a firmware
upgrade is recommended.
