・Indicating performance
| Indicating accuracy |

accuracy.)

(including cold junction temperature compensation accuracy) |

2.0 |
| Input

・Control performance

| Control
action |
PID action (with AT function):
If AT continues even if error assessment time has passed
after
AT starting, AT stops.
PID values for the channel of which AT has stopped, will
revert
to the value before AT is performed.
PI action: When derivative time is set to 0
PD action (With Auto-reset function): When integral time is
set
to 0
P action (With Auto-reset function): When integral and derivative
time are set to 0
ON/OFF action: When proportional band is set to 0.
Proportional band (P): 0-50
or 0-100
(When 4-digit is selected: 0.0-50.0
or 0.0 -100.0)
Integral time (I): 0-1000sec (Setting to 0 disables the function.)
Derivative time (D): 0-300sec (Setting to 0 disables the function.)
ARW: 0-100%
Proportional cycle: 1-50sec
ON/OFF action hysteresis: 0.1-100.0()
AT error assessment time: 1-240 minutes
|
| Control output |
Ch1-Ch20: Non-contact voltage (for SSR drive),
12V DC15%
Max. 20mA DC
Ch8 (common to non-contact voltage output): Relay contact, 1a
Control capacity: 3A 250V AC(resistive load)
1A 250V AC(inductive load cos =0.4)
Electric life: 100,000 cycles |
Integral computation
initial setting function |
When control starts, optimum value of integral
computation will be set as an initial value, based on the MV
when control is stable. |
Control
ON
timing
asynchronous function |
Prevents control output to be turned
ON simultaneously.
During control, plural channels output might be turned ON at
one time, however, this function prevents their outputs to be
turned ON synchronously. |
| Oil
temperature control |
If Ch8 proportional band is set to
0, and if Direct action is selected during Direct/Reverse action
selection, Ch8 will become oil temperature control.
(Default: Oil temperature control)
CH8 will become "Control allowed" status regardless
of External input 1, DIP switches (SW201-SW203) and Control
OUT/OFF selection. |
| Heater keep-warm
control |
If External input 6 is turned ON (Closed), control
is performed at Heater keep-warm value (common setting 100
or 212
to Ch1-Ch20).
SV and communication data will also become 100
or 212.
However, if Ch8 is of oil temperature control (when Direct action
is selected from Direct/Reverse action, and proportional band
is set to 0), Heater keep-warm control is not available for
Ch8. |
・Standard functions
| Temperature
alarm |
High/Low limit temperature alarm action (Low limit alarm
with standby)
(For CH8, only High limit alarm is available if it is for
oil temperature control.)
・Action:
Alarm output is turned ON if one or more channel alarm is
activated from Ch1 to Ch20.
If SV is changed, or if usual control/keep-warm control is
switched, the unit returns to standby status again.
Alarm function will be disabled if Control output OUT/OFF
is
selected or if External input 1 or 2 is OFF (Control Prohibited).
・Output
Relay contact, 1a
Control capacity: 3A 250V AC (resistive load)

Photocoupler insulation input
External power supply: 24V DC10%
Input impedance: 20k
・External input 1
ON (Closed): Block A (Ch1-Ch8) Control Allowed
OFF(Open): Control Prohibited
However, if Ch8 is of oil temperature control, Ch8 becomes
"Control Allowed" status regardless of External input
1 status.
[If "Control Prohibited" is selected in the status
of OFF (Open),
0 (zero) will be indicated on the PV display.]
・External input 2
ON (Closed): Block B (Ch9-Ch20) Control Allowed
OFF(Open): Control Prohibited
[If Control Prohibited is selected in the status of OFF(Open),
0 (zero) will be indicated on the PV display.]
・External input 3
ON (Closed): Ch4, Ch5 are subject to Block B, and are operated
under External input 2.
・External input 4
ON (Closed)でCh6, Ch7 are subject to Block B, and are
operated under External input 2.
・External input 5
ON (Closed): Ch19, Ch20 are subject to Block A, and are
operated under External input 1.
・External input 6
ON (Closed): Performs Heater keep-warm control.
However, if Ch8 is for oil temperature control, Heater
"Keep-Warm" option is not available for Ch8. |
