7. Setup Procedure
The following flowchart shows the setup procedure for UT32A-D/MDL.
Perform setup through communication or the LL50A Parameter Setting Software (sold
separately).
Install and wire a controller.
Monitoring and control of regular operations
Adjust PID using auto-tuning or manually for PID control.
(Set parameters through communication.)

Use LL50A
Software?
LL50A: Parameter setting software (sold
separately)
See the LL50A Parameter Setting Software
User’s Manual (IM 05P05A01-01EN).
Use LL50A with the controller turned on.
(The dedicated cable must be connected.
LL50A Light-loader adapter cannot be
used.)
The maintenance port is not isolated from
the PV input terminal. Use the port only for
maintenance purposes, such as for setting
the controller parameters.
To set parameters through
communication, you need to
create a program on the host
device side. For controller
parameter information (registers,
relays), see the following
manuals.
• For setup through RS485 serial
communication or Ethernet
communication, see the
UTAdvanced Series Communi-
cation Interface User’s Manual
(IM 05P07A01-01EN).
• For setup through an open
network, see the UTAdvanced
Series Communication
Interface (Open Network)
User’s Manual (IM 05P07A01-
02EN).
