„ Error code list
The following error codes may occur in the DL-EP1 and sensor amplifiers.
DL-EP1
Error ID
Number
Code Description Cause Actions
0
0 No error - -
51
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.
"Number of
Connectable Sensor
Amplifiers" (Page 2-3)
• 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.

Sensor Amplifiers" (Page 2-3)
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.
56
Current limitation
error
The number of connected
sensor amplifiers exceeds
the allowable range.
Use sensor amplifiers within
the allowable range.
57
Communication
error between
sensor amplifiers
An error occurred during
communication between
sensor amplifiers.
Check if there is a noise
source around the DL-EP1.
If the sensor communication
indicator is flashing red, turn
the power on again.
70
IP address
duplicate error
The IP address is the same
as another device.
Check the IP address
setting.
