＜ LINK does not ash ＞
Things to be checked
Check the connection of this unit.
Check conditions of the master unit
and slave unit.
＜ ALM is lit ＞
Things to be checked
Check the connection of I/O terminals
on the slave unit.
＜ ALM is ashing ＞
Things to be checked
Check the voltage (24V DC) of
external power supply to the master
unit.
＜ LINK and ALM ashes alternately ＞
Things to be checked
Check the address of the slave unit.
＜ LINK is lit and ALM is ashing: Model mismatching error (Failure in single unit simpli ed replacement) ＞
Things to be checked
Check the connection of the slave
unit.
Check the address of the slave unit.
Check the model of the slave unit.
Check the lot No. of the slave unit.
Disconnect this unit once, and then reconnect it.
1) If LINK on the master unit is ashing and LINK on the slave unit is lit, it is possible that the master
unit has a fault or power supply (24V-0V) is directly connected to the DP-DN pins of the slave unit.
*
If LINK is lit while ALM is ashing, it means a failure in single unit simpli ed replacement.
2) If LINK on the master unit is ashing and LINK on the slave unit is unlit, it is possible that the power
(24V DC) is not supplied to the master unit, there is a disconnection on the transmission line (DP,
DN), or the slave unit has been damaged.
3) If LINK on the master unit is not ashing, check the power supply to the master unit. Also, since there
is a possibility that some system error has occurred, refer to the user's manual of the master unit.
4) A slave unit incompatible with Ver.1.1 cannot be used in connection to the AnyWireASLINK system
for word transmission. Check the setting of the master unit, and lot No. of the slave unit.
Adjust the voltage of external power supply connected to the I/O side of the slave unit so that it falls
within the rating (21.6 to 27.6V).
In addition, ensure that there is no contact between and erroneous wiring of transmission lines.
Adjust the voltage of external power supply to the master unit so that it will be in the range from 21.6 to
27.6V. (Recommended voltage is 26.4V.) Check the total length.
Review the total length and wire diameter of transmission line so that the load will not exceed the current
limit supplied by the transmission line and adjust the connected load. (In the case of the wire size of
1.25mm
and total length of 50m or less, the current supplied by the transmission line is 2A.)

*
If ALM is ashing while LINK is lit, it means a failure in single unit simpli ed replacement.
The address of the slave unit is either unregistered or duplicated.
*
Take the following actions.
The slave unit cannot be used with the factory-set address.
1) Set an address correctly.
2) Check if there is a slave unit on which the indicator lamps are ashing in the same manner and reset
the addresses so that they are not duplicated.
Defective connections and the like may have caused single unit simpli ed replacement to fail.
Remove the slave unit after replacement, and make connections again.
When two or more replacement slave units are simultaneously connected, the single unit simpli ed
replacement function does not work.
Check if the address of the replacement slave unit is the same as the address before shipment (a bit
address of 511).
*
If the address of the replacement slave unit is not the same as the address before shipment, the single
unit simpli ed replacement function does not work.
Check if the replacement slave unit is of the same type as that of the slave unit before the replacement.
Check if the function version for the replacement slave unit is older than that of the slave unit before the
replacement.
*
If the function version of the replacement slave unit is older, the single unit simpli ed replacement
function does not work.
