- AnyWireASLINK
transmission signal
is not connected.
- Power supply for
the AnyWireASLINK
system itself is not
turned on.
- The DP-DN line is
directly connected to
24-0V power supply.
- Confirm that there is no disconnection
between the ASLINKAMP and the
AnyWireASLINK system, and recover
the connection.
- Confirm the power status of the
AnyWireASLINK system, and turn on
the power.
- Re-connect to the AnyWireASLINK
system.
- The ASLINKAMP
maintains the
address 255
(default setting).
- Set any address other than 255.
- The ASLINKAMP has
an address redundant
with another unit.
- Look for the other unit which has the
same error indication, and set any
address different from it.
- The internal power
voltage of the
ASLINKAMP has
been reduced.
- Decrease the number of units
connected to the same
AnyWireASLINK system.
- Shorten the transmission line between
the ASLINKAMP and the master unit.
When the following errors are indicated on the display window of this
product, take measures as shown below.
Confirm whether analog output is connected or whether there is
disconnection, etc.
Confirm the input value to use within the specifications range.
Confirm the following issues to eliminate corresponding factors.
- Is the voltage of the 24 DC power supplied to the AnyWireASLINK master is
within the allowable voltage range?
- Is there any looseness or contact failure at the connection part of the main
line or branch line?
- Does the current of the unit or connection load suit system conditions?
Take measures as follows in the following case.

[E-0303]
The set parameter is
incorrect.
Check the parameter correspondence table and set
the correct parameter.
- Is wiring correct?
→
Re-confirm the analog port and the connection of the transmission line.
- Is power fed to the AnyWireASLINK system?
→
Confirm the power supply.
- Has address setting been performed?
→
Perform address setting.
- Are you using within the rated input range?
→
Use within the rated detection range.
- Is wiring correct?
→
Reconfirm the transmission line connection, and that the transmission signal is
applied.
- Is power fed to the AnyWireASLINK system?
→
Confirm the power supply.
- Was setting performed with the protective cover open?
→
Open the protective cover. Setting cannot be performed with the cover closed.
- Is the set parameter correct?
→
Check the parameter correspondence table and set the correct parameter.
When the following errors are indicated on ARW-04, take measures as
shown below.
