(4) Standby (STBY) / execution (EXE)
The controller is equipped with a standby mode for temporarily halting controller execution.
This operation mode is switched on the “0-1 standby action setting screen.”
In the case of fixed value control (FIX mode), STBY (standby) / EXE (execution) is displayed.
In the case of program control (PROG mode), RST (reset: stop) / RUN (program execution) is displayed.
If EXE1 (RUN1) or EXE2 (RUN2) is selected on the “4-28 – 4-31 DI mode setting screen”, external control input (DI) is given
priority and settings cannot be made on the 0-3 screen.
c
The RUN lamp is lit green while the controller is operating and it goes off during standby.
d
Controller output for standby is 0%.
e
When standby is executed, auto tuning (AT) is canceled.
f
When standby is executed in the manual input mode, the manual input mode is canceled.
g
When the power is turned off while the controller is in standby mode, standby mode continues when the power is turned back on.
h
If event standby action is specified when switching to execution mode (EXE) from standby mode (StbY), the specified standby
action is executed.
i
If event latching is not engaged in the standby mode, alarms (Hd, Ld, od, id, HA, LA) are not output.
(5) Event setting
Types of event must be set before setting event values.
Modifying the types of event code however initializes setting values (data) related to events.
1) Types of event (alarm type) setting
Select type code from among Hd, Ld, od, id, HA, LA, So, EXE(run), HC1, HC2, StPS, PtnS, EndS, hoLd, ProG, u_SL, d_SL
on the “4-2 event 1 type setting screen of screen” group 4 with the key / key and enter the event type with the key.
Set event 2 and event 3 on the “4-7 event 2 type setting screen” and “4-12 event 3 type setting screen” in the same manner.
The types of event for which event values can be set are the following 6 types:
Event type (alarm type) code:
: higher limit deviation, : lower limit deviation,
: outside higher/lower limit deviation, : inside higher/lower limit deviation,
: higher limit absolute value, : lower limit absolute value
If : none, : scaleover, : EXE signal (: RUN signal), : heater 1 break/loop alarm, or : heater 2
break/loop alarm is selected, event values cannot be set.
2) Event values setting
Event values are set on the “0-12 event 1 setting values setting screen”, “0-13 event 2 setting values setting screen” and “0-14
event 3 setting values setting screen.” Type of event is displayed when one of the previously mentioned 6 types of events is selected.
Event values are set by selecting setting range by pressing the key / key on the 0-12, 0-13 or 0-14 screen.
When the event value setting has been decided, enter by pressing the key and the decimal point stops flashing.
Setting range: Higher limit deviation or lower limit deviation -1999 – 2000 unit
Outside or inside higher/lower limit deviation 0 – 2000 unit
Higher limit absolute value or lower limit absolute value Within measuring range
Event values cannot be set during auto tuning (AT) execution. AT must first be canceled.

(6) Multi SV (target set values)
1) Multi SV
You can set 3 types of target set values (SV). (SV1, SV2, SV3)
SV values are set on the “1-3 – 1-5 FIX control SV1 – SV3 setting screen” and execution SV No. is selected on the “1-2
execution SV No. selection screen.”
PID No. during multi SV is SV1/PID1, SV2/PID2 and SV3/PID3.
2) External selection switching of multi SV
If equipped with external control input DI, if ESV2 is allocated to DI, execution SV can be selected from among SV1 – SV3 by
DI input.
Using 2 points of DI, DI to be used for SV selection is allocated on “4-28, 4-29 DI1 and DI2 mode setting screen.”
See “8-4. External control input (DI) .”
