OUT2 cooling method
• Selects OUT2 cooling method from air, oil or water cooling.
(Fig. 8.3-5)
• Selection item:
air/
Air cooling (Linear characteristics)
oil/
Oil cooling (1.5th power of the linear characteristics)
wat/
Water cooling (2nd power of the linear characteristics)
Available when EV2 option {When
/020
(Heating/Cooling control output) is selected in
[Event output EV2 allocation]} is ordered, or when DS, DA or EV3D
option is ordered.

OUT2 proportional band
• Sets the OUT2 proportional band of the PID block number selected in [PID
block number].
The PTN/STEP Display indicates the PID block number selected in [PID block
number].
When set to 0 or 0.0, OUT2 becomes ON/OFF control, and the action selected
in [OUT2 cooling method] will be disabled.
• Setting range:
Thermocouple, RTD input without decimal point: 0 to Input span
( )
Thermocouple, RTD input with decimal point: 0.0 to Input span
( )
DC voltage, current inputs: 0.0 to 1000.0%
Available when EV2 option {When
/020
(Heating/Cooling control output) is selected in
[Event output EV2 allocation]} is ordered, or when DS, DA or EV3D
option is ordered.

OUT2 proportional cycle
• Sets OUT2 proportional cycle.
For relay contact output, if the proportional cycle time is decreased, the
frequency of the relay action increases, and the life of the relay contact is
shortened.
Factory default value is different depending on the output type as follows:
Relay contact output [EV2, EV3(DR)]: 30 seconds
Non-contact voltage output (DS, EV3DS): 3 seconds
Direct current output (DA, EV3DA): Not available
• Setting range: 0.5,
1 to 120 seconds
Available when EV2 option {When
/020
(Heating/Cooling control output) is selected in
[Event output EV2 allocation]} is ordered, or when DS, EV3(DR), EV3DS option is
ordered.
