Insulation resistance
10MΩ or greater at 500Vdc
In the case of the above Circuit insulation configuration (*), because the communication and output
terminals are not isolated from one another, the insulation resistance test must not be carried out.

8.2 Optional functions
Serial communication [Option code: CR5]
When this option is applied, setting of the items; Temperature alarm, Heater burnout alarm
and Loop break alarm can be performed by serial communication. However, as to the
Event output, the item selected in Event output function selection has priority.
When the option [SV2] or [W1X] is applied, the option [CR5] cannot be applied together.
Following operations can be performed by the external computer.
(1) Reading and setting of the Main setting value, PID values and others
(2) Reading of input value and action status
(3) Change of the function
