(2) Proportional cycling time
The correlation between proportional cycling time and control output are as shown in the following figure.
①Output 20%
②Output 60%
(3) Control output characteristics
Control output characteristics can be set independently for output 1 and output 2.
For heating, set to RA (reverse action) and for cooling set to DA (direct action).
Output characteristics
Control output with 2-output characteristics is as shown in the following figure.
c
is heating/cooling control and
d
is heat + heat control.

: Target set values (SV) ：DB (dead band)
Dead band: Shifts proportional band of control output2 for setting value.
8-5. External control input (DI)
Input must be retained for at least 250 ms to receive external control input of the SRS10 Series.
Assignment by DI input is conducted on the “4-28 – 4-31 DI mode setting screens.”
Function assigned to DI cannot be conducted by key operation.
(1) Controller action execution EXE1 (RUN1)
You can toggle between controller action execution/stop. Level action.
DI input OFF: Switches to standby (reset). SRS10 stops action.
DI input ON: Controller action is executed. PID operation control is executed (program control execution).
・
NOTE: If DI is ON when power is applied, controller action is executed immediately after power is applied.
(2) Controller action execution EXE2 (RUN2)
Execution/stop is switched each time DI input is turned ON. (edge action).
NOTE: If DI is ON when power is applied, controller action is not executed immediately after power is applied.
(3) Manual output (MAN)
Switches to manual output. Level action.
DI input OFF: Ordinary feedback control action is executed.
DI input ON: Control output is executed manually; feedback control is not executed.
(4) Auto tuning execution (AT)
Auto tuning can be executed from outside. Edge action.
Once DI input is turned ON, auto tuning is executed.
If SV No. is switched by DI during AT execution, it is not applied until AT is finished.
AT in execution cannot be released by DI. Front key is used for releasing AT in execution (0-15 screen).
