Main control Mode to set the proportional cycle of Main control.
proportional cycle setting Setting range: 1 … 120 s
Setting value [Factory adjusted as 30 s to Relay contact output
type, and 3 s to Non-contact voltage output type]
MODE This setting item is not available to Current output type.
When the ON/OFF action is selected in Control action
designation (page 10), this display is not available.
With the Relay contact output type, if the Proportional
cycle time is decreased, the frequency of the relay
action increases, and the life of the relay contact
is shortened.
Cooling control Mode to set the proportional cycle of Cooling
proportional cycle setting control.
Setting value Setting range: 1 … 120 s
[Factory adjusted as 30 s for Relay contact output
MODE type, and 3 s for Non-contact voltage output type]
This display is indicated only when the option [DR2] or [DS2]
is applied.
When the ON/OFF action is selected in Control action
designation (page 10), this display is not available.
Manual reset setting Mode to set the reset value to correct the offset
Setting value (Deviation between SV and PV when equilibrium status).
MODE Setting range: ± proportional band converted value
However, when TC or RTD input, in the range,
–199.9 … 999.9 °C (°F)
when DC input, in the range,
–1999 … 9999
[Decimal point place follows the selection.]
[Factory adjusted as 0.0 °C]
This display is indicated only when PD action is designated in
the Control action designation (page 10).
Manual reset setting method:
When SV>PV, set the positive + value (SV–PV).
When SV<PV, set the negative – value (SV–PV).
