Unassigned ID
error
The main unit assigned no ID
within 10 seconds after the
DL-EP1 had been started.
•
Check if the number of
connected sensor
amplifiers exceeds the
maximum number of
sensor amplifiers that can
be connected to the main
unit.
"Connectable Sensor
Amplifiers" (Page 1-2)
•
Check the connection with
the sensor amplifiers and
then turn the power on
again.
If this error cannot be
recovered, contact your
nearest KEYENCE office.
52
Start-time
communication error
Communication between
sensor amplifiers ended
abnormally before ID
assignment completion.
Check the connection with
the sensor amplifiers and
then turn the power on again.
If this error cannot be
recovered, contact your
nearest KEYENCE office.
53
Unsupported
sensor amplifier
connection error
A sensor amplifier not
supported by the DL-EP1 is
connected.
Check the model of the
connected sensor amplifier
and remove the sensor
amplifier if it is not supported
by the DL-EP1.
54 Mixed model error
Sensor amplifiers outside the
specifications have a mixed
connection.
Check if the models are
mixable.
55
Start-time
communication error
ID number assignment is
successful but
communication failed during
the subsequent initial
communication.
Check the connection with
the sensor amplifiers and
then turn the power on again.
If this error cannot be
recovered, contact your
nearest KEYENCE office.
