| SV ramp function |
When the SV is adjusted, it approaches the new SV by the preset rate-of-change (/min, /min)
When the power is turned on, the control starts from the PV and approaches the SV by the rate-of-change. |
| Auto/Manual control switching |
Auto/Manual control can be switched by keypad.
If control action is switched from automatic to manual and vice versa, balanceless-bumpless function works to prevent sudden MV change.
If control action is switched to manual, the manual MV is indicated on the display. (CHx display flashes.)
When power is turned on, control action starts from its previous controller status (last shutdown). |
| Timer spec |
Selects either Control timer or Delay timer function.
-Control timer:
Timer starts when CH1 input exceeds Control timer start temperature.
After Control timer setting time has elapsed, control (for DC current output, output low limit) and alarm action will stop.
-Delay timer:
When DI input is ON (Closed), the timer starts.
Timer output turns ON after ON delay timer time has passed.
Timer output turns OFF after OFF delay timer time has passed. |
Cascade control
(Block function) |
To control one process, 2 inputs [CH2 as a master (1st-order controller), and CH1 as a slave (2nd-order controller)] are used for more advanced control.
MV is calculated from PV and SV of the master (CH2), and is used as SV of the slave (CH1), with which CH1 control computation is carried out, then outputs from CH1 control output.
[CH2 control output will be OFF (0mA for DC current output) or OUT2 (Cooling output) for Heating/Cooling control.]
MV (0 to 100%) of the master (CH2) corresponds to the SV (External setting low limit to External setting high limit) of the slave (CH1). |
| Heating/Cooling control output (Block function) |
This is 1ch Heating/Cooling control output spec. CH1 will be Heating output (OUT1) and CH2 will be Cooling output (OUT2), followed by control performance.

CH1 PV difference (CH1-CH2) input
(Block function) |
Temperature difference between CH1 and CH2 (CH1-CH2) will be the input value for CH1, and control is performed using this value.
PV = (CH1 PV - CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and difference depend on the reference channel. |
CH1 PV addition (CH1+CH2) input
(Block function) |
Addition value of CH1 and CH2 will be the input value for CH1, and control is performed using this value.
PV = (CH1 PV + CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and addition depend on the reference channel. |
CH2 PV difference (CH2-CH1) input
(Block function) |
Temperature difference between CH1 and CH2 (CH2-CH1) will be the input value for CH2, and control for CH2 is performed using this value.
PV = (CH2PV - CH1PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and difference depend on the reference channel. |
CH2 PV addition (CH1+CH2) input
(Block function) |
Addition value of CH1 and CH2 will be the input value for CH2, and control is performed using this value.
