The setpoints of the ORB, ORH and ORL parameters are only

effective when a sensor grounding alarm is used.

The OR parameter represents the moving average (for 5 cycle times)

of the control output and is not a setpoint.

If you become unsure of key operation during parameter

setting, hold down the key for more than 3 seconds.

This returns you to the display at power-on

(i.e., operating display).

Set the data item PV Input Type “IN” to the OFF

option to leave the PV input type undefined.

NOTE

Changing the registered value of a setup parameter

may cause the registered value of an operating pa-

rameter to be initialized automatically. Thus, when

you have changed a setup parameter, always check

that the registered value of the operating parameter

is appropriate. If it is initialized to default, reset it to

the required value.

When shipped from the

factory, this parameter

appears first after

power-on.

This parameter

is not to be set.

Note 1: The fault diagnosis output turns on in case of

input burnout, A/D converter failure, or refer-

ence junction compensation (RJC) failure. The

control output in case of input burnout or A/D

converter failure is set to the value of the PO

(Preset Output Value) setup parameter. In case

of RJC failure, the controller continues control

under the condition of “RJC = OFF”.

Note 2: The FAIL output is on during normal operation

and turns off in case of failure.
