8-5. External control input (DI)
Input must be retained for at least 250 ms to receive external control input of the SRS10A 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. (DI input is prioritized.)
However, AT and unlatching can be conducted by key operation even if assigned to DI.
(1) Controller action execution EXE1 (RUN1)
You can toggle between controller action execution/stop. Level action.
DI input OFF: Switches to standby (reset). SRS10A 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).
(5) SV external selection (ESV2)
Setting values of SV1 – SV3 can be switched to SV being executed. DI is level action using 2 points. Assignment to DI1 or DI2 can be
set.
Assigning/setting SV external selection to DI1 automatically allocates it to DI2 as well, so DI2 cannot be selected.
Assigning/setting SV external selection to DI2 automatically allocates it to DI3 as well, so DI3 cannot be selected.
When assigned to DI1
When assigned to DI2
DI2 DI1 Selected SV No. DI3 DI2 Selected SV No.
0 0 1 0 0 1
0 1 1 0 1 1
1 0 2 1 0 2
1 1 3 1 1 3
SV No. and PID No. being executed correspond to SV1/PID1, SV2/PID2, and SV3/PID3.
