Error information list

Output

Sensor amplifier ID numbers 01 to 08 are assigned to bits 0 to 7, respectively.

For details of communication methods, see

"Reading an output from a sensor

amplifier" (page 3-15).

Initialization error

Error encountered during
initialization.

Check the number of con-
nected sensor amplifiers and
the connection to the sensor
amplifiers, and then turn off the
power and back on. If the error
cannot be recovered, contact
your nearest sales office.

04h

Mixed connection error

A foreign sensor amplifier (i.e.,
one that cannot be intermixed)
is connected.

Remove the foreign sensor
amplifier.

06h

Number-of-units error

More sensor amplifiers are
connected than are permitted.

Observe the number of con-
nectable sensor amplifiers.

System error

An error occurred in the internal
system.

Check the connection to the
sensor, and then turn off the
power and back on. If the error
cannot be recovered, contact
your nearest sales office.

Model error

There is connected a sensor
amplifier of a model incompati-
ble with the DL-DN1.

Connect a sensor amplifier of a
compatible model.
