Status details
Error information list
Name Description Reading range
Error status
An error occurred with the DL-DN1 or sensor amplifier, or the
DL-DN1 is not communicating properly with the sensor amplifier.
If an error exists, the error ID number and error code are stored. 0: No Error
1: Error
Sensor ready The sensor amplifier has started and is ready. 0: Starting
1: Ready
Error ID number
The error ID number is stored in the range of bit 0 (LSB) to bit 4
(MSB).
"Error information list"
(page 3-8)
Error code
The error code is stored in the range of bit 8 (LSB) to bit 12
(MSB).

Description Cause Corrective action
00h
01h Initialization error Error encountered during
initialization. Check the number of
connected sensor amplifiers
and the connection to the
sensor amplifiers, and then
cycle power. If the error
remains, contact your nearest
sales office.
04h Mixed connection error A foreign sensor amplifier (i.e.,
one that is not compatible) is
connected. Remove the foreign sensor
amplifier.
06h Number-of-units error More sensor amplifiers are
connected than are permitted. Check the number of
connected sensor amplifiers.

02h/
04-07h System error An error occurred in the internal
system. Check the connection to the
sensor, and then cycle power. If
the error can not be corrected,
contact your nearest sales
office.
03h Model error There is a sensor amplifier
connected that is incompatible
with the DL-DN1. Connect a sensor amplifier of a
compatible model.
