Procedure
Relay cannot receive the
requirement frame from
BCU.
(The timing coordination of
sending and receiving switch
control is irregular in half-
duplex communication.)
BCU
Check to ensure that there is a
margin of more than 15ms between
receiving the reply frame from the
relay and transmitting the next
requirement frame from the BCU.
The requirement frame from
the BCU and the reply frame
from relay contend.
(The sending and receiving
timing coordination is
irregular in half-duplex
communication.)
BCU
Check to set the time-out for the
reply frame from the relay.
Time-out setting: more than 100ms
(acceptable value of response time
50ms plus margin)

HMI does not
display
IEC103 event
on the SAS
side.
The relevant event sending
condition is not valid.
RY
Change the event sending condition
(signal number) of the IEC103
configurator if there is a setting
error. When the setting is correct,
check the signal condition using the
programmable LED, etc.
The relevant event
Information Number (INF)
and/or Function Type (FUN)
may be different between the
relay and SAS.
RY
SAS
Match the relevant event
Information Number (INF) or
Function Type (FUN) between the
relay and SAS.
The relay is not initialised
after writing the IEC103
configurator setting.
RY
Check the sum value of the IEC103
setting data on the LCD screen.
When differing from the sum value
on the IEC103 configurator,
initialise the relay.
It changes to blocked mode.
RY
Change the setting
[RS485_1_BRATE_SW] to Normal.
