(DL-PD1)
16 Unassigned ID error
The number of sensor amplifiers increased during
operation. Check the connection with the sensor
amplifier.
17 Start-time Communication error
Check the connection with the sensor amplifier
and cycle the power.
18
Unsupported Sensor Connection
error
There is connected a sensor amplifier of a model
incompatible with the DL-PD1. Connect a sensor
amplifier of a compatible model.
19 Mixed Model error
A foreign sensor amplifier (i.e., one that cannot be
intermixed) is connected. Remove the foreign
sensor amplifier.
20 Start-time Communication error
Check the connection with the sensor amplifier
and cycle the power.
21 Current Limitation error
The current limitation exceeds the allowable
range. Check the allowable range of the number of
the sensor amplifiers.
22
Communication error between
Sensors
An error exists in the communication between
sensor amplifiers. Check the connections of the
sensor amplifiers, and then turn off the power and
back on.
23 Changed Station Address error
The station address was changed during
operation. If it was not an intentional change,
check the correct station address and set.
