6.3 Basic Operation Procedures
Basic operation procedures are shown below.
Setting Example
CH2 function : Used as a CH2 controller (2ch controller spec).
Input
: Pt100: -199.9 to 850.0
(for CH1, CH2)
Control action : PID control (P, I, D and ARW values are automatically set by performing AT)
(for CH1, CH2)
Alarm 1 type : High limit alarm (for CH1, CH2)
Alarm 1 value : 10.0
(for CH1, CH2)
SV
: CH1: 200.0
CH2: 210.0
Operation Procedures
1. Operation before running
Turn the load circuit power OFF, and turn the power supply to
the controller ON.
2. CH1 function group
CH2 function group
Select each input type, Alarm 1 type, etc. in the CH1, CH2
function groups.
1
Select [
: Pt100 -199.9 to 850.0
] in
[
: Input type].
2
Select [
: High limit alarm] in [
: Alarm 1 type].
Setting items
3
and
4
will be indicated.
Set them as needed.
[Note]
When an Alarm type is changed, the Alarm value
defaults to 0 (0.0). Therefore set it again.
3
Set the Alarm 1 hysteresis in [
: Alarm 1 hysteresis].
4
Set the Alarm 1 action delay timer in [
: Alarm 1
action delay timer].
3. SV group
Set the SV in the SV group.
5
Set to 200.0
in [
: CH1 SV].
6
Set to 210.0
in [
: CH2 SV].
4. Start the controller
Turn the load circuit power ON.
Control action starts so as to keep the control target at the SV.
5. AT Perform
Perform AT in the CH1, CH2 parameter groups respectively.
7
Select [
: AT Perform] in [
: AT/Auto-reset
Perform/Cancel].
The AT indicator flashes while AT is performing.
The AT indicator goes off after AT is finished.
[Note]
After AT is finished, P, I, D and ARW values are automatically
set. Since these values are internally memorized, it is not
necessary to perform AT again as long as the process is the
same.
6. CH1 parameter group
CH2 parameter group
Set each Alarm value in the CH1, CH2 parameter groups after
AT is finished.
8
Set the value to 10.0
in [
: Alarm 1 value].
Setting items
1
to
8
are indicated in Section 7. Key Operation Flowchart (Pages 22, 23).
