ARW setting
• Sets ARW (anti-reset windup).
• Available only when PID is the control action.
• 0 to 100%
OUT1 proportional cycle setting
• Sets proportional cycle for OUT1.
• Not available for ON/OFF action or DC current output type.
With the relay contact type, if the proportional cycle time is decreased, the fre-
quency of the relay action increases and the life of the relay contact is shortened.
• 1 to 120 seconds
OUT2 proportional cycle setting
• Sets proportional cycle for OUT2.
• Not available if OUT2 is ON/OFF action
• Available only when Heating/Cooling control (option) is applied
• 1 to 120 seconds
A1 value setting
• Sets action point for A1 output. Setting the value to 0 or 0.0 disables the function (except
process high alarm and process low alarm).
• Not available if No alarm action is selected during A1 type selection
• Refer to (Table 5.2-1).
A2 value setting
• Sets action point for A2 output. Setting the value to 0 or 0.0 disables the function (except
process high alarm and process low alarm).
• Not available if No alarm action is selected during A2 type selection
• Refer to (Table 5.2-1).
Heater burnout alarm value setting
.
• Sets the heater current value for Heater burnout alarm.

*1: For DC input, the input span is the same as the scaling span.
*2: For DC input, input range low (or high) limit value is the same as scaling low (or high) limit value.

Set value lock selection
• Locks the set values to prevent setting errors.
The setting item to be locked depends on the selection.
• When Lock 1 or Lock 2 is selected, PID Auto-tuning or Auto-reset cannot be carried out.

(Lock 1): None of the set values can be changed.
(Lock 2): Only main setting mode can be changed.
(Lock 3): All set values except Input type can be changed. However, they return to
their previous value after power is turn ed off because they are not saved in t he non-
volatile memory. Be sure to select Lock 3 when cha nging the set value freque ntly via
communication function. (If the value set by the communication function is the same as
the value before the setting, the value
Do not change any setting item in Auxiliary function setting mode 2. If any item in
the mode is changed, it will affect other setting items such as the SV and Alarm
