0-15 Auto tuning (AT) action control screen
Initial value: oFF
Setting range: oFF, on
AT is executed by on selection and is canceled by oFF selection.
This screen is not displayed for manual output or for output 1
proportional band (P) OFF setting.
Not displayed if STANDBY is set for 0-1 standby action setting
screen. During AT execution, key operation other than AT cancel,
key lock setting and communication mode is not accepted.
For AT action, see 5- 5 (3).
0-16 Start pattern No. monitoring screen
Display screen for program operation.
Initial value: 1
Setting range: 1, 2, 3, 4
Differs according to number of patterns (max. 1, 2, 4)
Displays/sets starting pattern No.
0-17 Unlatching screen
Initial value: rSt1
Setting range: rSt1, rSt2, rSt3, ALL
Note: Displayed only when event latching is selected.
If event latching is ON, even if event conditions no longer exist
after event action, the event continues to be output. (Event self-
hold)
Cancels self-hold of the event.
Setting and corresponding event No:
rSt1：EV1, rSt2：EV2, rSt3：EV3,
ALL：EV1, EV2, EV3
If latching can be canceled, the decimal point for the lowest digit
on the concerned setting screen flashes. Pressing the key
cancels the concerned event.
To 0-0 Basic screen
FIX control (fixed value control) setting
0-0 Basic screen
Setting related to multi SV (target set values) for fixed value
control.
1-0 FIX setting initial screen
Displayed by pressing the
key on the basic screen.
Fixed value for no programming function.
Set to multi SV fixed value control in using multiple target set
values.
1-1 FIX control ON/OFF switching screen
Can be switched to fixed value control if equipped with
programming function.
Initial value: on
Setting range: on, oFF
On: fixed value control, oFF: Program control
1-2 Execution SV No. setting screen
Displays execution SV No. used by fixed value control.
Initial value: 1
Setting range: 1 – 3
1-3 Target set values SV1 setting screen
Sets target set values used by fixed value control.
Initial value: 0
Setting range: Within SV limiter range
1-4 Target set values SV2 setting screen
Same as 1-3 screen above except SV2 instead of SV1.
Sets target set values used by fixed value control.
1-5 Target set values SV3 setting screen
Same as 1-3 screen above except SV3 instead of SV1.
Sets target set values used by fixed value control.
To 1-0 screen
PID setting
PID setting screen group
With the SRS10 Series, you can have 3 types of PID constants.
In the case of fixed value control (FIX), target set values SV1, SV2 and SV3
correspond to PID1, PID2 and PID3 respectively.
In the case of program control, an execution PID No is allocated to each step.
1-0 FIX setting initial screen
Pressing the key on the 1-0 screen switches to the PID1
setting screen.
2-0 PID setting screen
PID1 PID2 PID3 PID1
2-1 screen 2-1 screen
The numbers at the end of the upper display are PID No.s that
correspond to SV1, SV2 and SV3 respectively.
Pressing the key displays the screen in the order of
PID1→PID2→PID3→PID1.
Pressing the key displays the screen in the order of
PID1→PID3→PID2→PID1.
Pressing the key on these screens switches to screen group 3
(equipped with programming function) or the basic screen.
There are no setting items for this screen. Pressing the
key
displays the initial output 1 PID1 proportional band (P) setting
screen.
Pressing the key displays the last output 2 higher limit setting
screen.
Note：Set PID2 and PID3 on the 2-0 – 2-16 screens just
as with PID1.
2-1 Output 1 PID1 proportional band (P) setting screen
Initial value: 3.0 (%)
Setting range: oFF, 0.1 – 999.9 (%)
There is basically no need to set if auto tuning (AT) is executed.
For information on proportional band, see 8-3 (1). If oFF is set,
ON-OFF (2 position) action is set.
2-2 Output 1 PID1 hysteresis (dF) setting screen
Initial value: 20 (unit)
Setting range: 1 – 999 (unit)
Sets “hysteresis” for ON–OFF action.
Displayed if P = oFF is set on 2-1 screen.
2-3 Output 1 PID1 integral time (I) setting screen
Initial value: 120 (seconds)
Setting range: oFF, 1 – 6000 (seconds)
There is basically no need to set if auto tuning (AT) is executed.
For information on integral time, see 8-3 (2).
This screen is not displayed when P = OFF.
