D2
(8D2)
Inconstancy in Number
of RCON-EC Units
Cause: 1) The number of connected EC connection units differs from
the number of connection unit set in the gateway
parameter.
2) The number of EC connection units has exceeded the
maximum connectable number (4 units).
Countermeasure: 1) Match the number of the EC connection units
and the number of units in the setting.
2) Set the number of EC connection units within
four units. In case it exceeds four units, have
two or more units of the EC gateway unit.
DC
(8DC)
RCON-EC Unit
Communication Error
Cause: There was a communication error in the total frame
communication between the EC gateway unit and EC
connection units.
1) A link connector is not appropriately connected
2) Internal signal line is broke
3) A terminal unit is not connected properly
4) Communication error due to noise influence
Countermeasure: 1) 2) Check that the link among units is well
established. Disconnect the link among units
once and reconnect it. In case the failure occurs
even after rebooting the power, contact IAI.
3) Confirm that the connection of a terminal unit is
well established.
4) Take a countermeasure for noise in such a way
as to change the cable layout.
DD
(8DD)
Unit connection check
signal error
Cause: Units may not be correctly connected.
1) Connector or SCON cable connector is not correctly connected.
2) Interior signal line or SCON connection cable is
disconnected.
3) Terminal unit or terminal connector (for SCON) has not
been mounted.
Countermeasure: 1) 2) Confirm that units are firmly connected
together. Disconnect the units and then connect
them again. Contact IAI if this reoccurs even
after turning ON the power again.
3) Mount the terminal unit or terminal connector.
FA
(8FA)
CPU error
Cause: Abnormal reset detected in gateway board interior CPU.
Countermeasure: Reboot the power. If it occurs again, contact IAI.
FFF Power ON log A log created when power is turned ON (not an error)
