System Errors

Serial Master Station
MS indicator
Lit red A fatal error has occurred (watchdog timer error,
EEPROM error, or hardware error).
Replacement of the WT30 Terminal is required.
Flashing red A non-fatal error has occurred.
Illegal switch settings have been made.
Recovery is possible by correcting the settings.
An EEPROM checksum error has occurred.
WS indicator
Lit red A fatal wireless communications error has
occurred.
A code sense error has occurred.
Flashing red A non-fatal wireless communications error has
occurred. A verification error (I/O size mismatch)
has occurred.
I/O Slave Stations

Use the information provided here to identify the cause and location of errors
that may occur in the WT30 Terminals and perform troubleshooting.
Errors that occur in the wireless system are classified as hardware errors and
wireless communications errors. WT30 Terminal hardware errors and wireless
communications errors can be checked using the indicators.

Countermeasure
First reset the power supply or initialize the
WT30 Terminal. If the WT30 does not recover,
contact your OMRON representative.
Check the switch settings and make sure they
are correct.
Initialize the WT30 Terminal. If it does not
recover, replace the WT30 Terminal. Contact
your OMRON representative for details.
Countermeasure
A WT30 or WD30 is already present on the
same wireless channel. Change the frequency
channel and start up the WT30 Terminal again.
The I/O size for the I/O Slave Station registered
in the Serial Master Station is different from the
I/O size of the I/O Slave Station performing com-
munications. Refer to 5-3 Replacing WT30 Ter-
minals on page 73 and either re-register the I/O
Slave Station to perform communications or
change the I/O Slave Station model (change
from 16 inputs to 8 inputs/8 outputs or from 8
inputs/8 outputs to 16 inputs).
Countermeasure
First reset the power supply or initialize the
WT30 Terminal. If it does not recover, contact
your OMRON representative.
Check the switch settings and make sure they
are correct.
Initialize the WT30 Terminal. If it does not
recover, replace the WT30 Terminal. Contact
your OMRON representative for details.
