Troubleshooting
Cause
Cables are not connected correctly. Check the output circuit and the
The signal line is disconnected.
The signal logic is not correct.
The RESET input line is short-
circuited.
The non-measurement setting is
set to "CLAMP", and measurement
cannot be performed.
Cables are not connected correctly. Check the output circuit and the
The signal line is disconnected.
The voltage and current values are
off the meter.
An oscilloscope or a high-speed A/
D board is being used.
Cable wirings are wrong.
Cables are not connected correctly.
Communication settings are wrong. Set the same communication setting
The Ethernet cable is not
connected correctly.
The IP address and subnet mask
are not set correctly.
The Sensor Controller and an
external device are not connected
at a 1:1 ratio.
The Ethernet cable is disconnected
or about to be disconnected.
The industrial switching hub is
faulty (when the switching hub is
used).
The security setting is not
appropriate.
The node address setting switch is
not set correctly.
Devices are not connected
correctly to the EtherCAT
connector (input/output).
The key lock setting is turned ON.
Countermeasure
wiring for proper connection.
Check the logic of the signal.
Check the input circuit and the wiring
for proper connection.
Set the non-measurement setting
correctly. By selecting the non-
measurement setting to "KEEP", the
judgment result before measurement
is disabled can be output.
wiring for proper connection.
Set the correct monitor focus based
on the measured value.
Use of these devices may reduce the
resolution. Change the monitor focus
to minimize the affect.
Check the wiring to ensure proper
connection.
for both the Sensor Controller and
the external devices.
Use a cross cable when connecting
the controller directly with the
personal computer.
Set the IP address and subnet mask
correctly.
* To enable the settings, restart the
Controller.
Connect the Sensor Controller and
an external device at a 1:1 ratio.
Check if the Ethernet cable is
disconnected.
Check if the industrial switching hub
is faulty.
Check if the communication is
blocked due to the firewall setting on
the external device.
Check to make sure that the node
address setting switch is set
correctly.
Check to make sure that devices are
connected correctly to the EtherCAT
connector (input/output).
Turn OFF the key lock setting.
