■ WIRING DIAGRAM
■Wiring Precautions:
1. Before wiring, verify the controller label for correct model number and options.
2. For thermocouple input, use the appropriate compensation wire. And note the polarity of input signal.
avoid noise induction, keep input signal wires away from instrument power lines, load lines and power lines of

CODE DESCRIPTION RANGE Default
Set point value of control
Alarm 1 set point value/Timer set value while A1FU is set to
T.on or T. off, the unit can be HH.MM or MM.SS. It depends on
the “P.tnE” parameter.
Alarm 2 set point value/ Timer set value while A2FU is set to
T.on or T. off, the unit can be HH.MM or MM.SS. It depends on
the “P.tnE” parameter.
：Auto-tuning is disable
：Standard type auto-tuning.
Autotune PV is compared wit SV during auto tuning.
：Low PV type auto-tuning.
PV is compared with SV-10%FS during Auto-tuning.

activating the Auto tune function. If desired, the user can later
adjust this parameter to better suit the application. When PB=0.0,
this parameter will be not available. When set to zero, Pb & td ≠ 0
for PI control
Proportional cycle time of output 1
Proportional band variable for secondary control output (cooling).
Set 0.0 for ON/OFF
Integral time for secondary control output. When PB=0.0, this
parameter will be not available. When set to zero, Pb & td ≠ 0 for
PD control
Derivative time for secondary control output. When Pb=0.0, this

Dead band value. This defines the area in which output 1 and
output 2 are both active (negative value) or the area in which
output 1 and output 2 are both inactive (positive value)
Set point offset. This value will be added to SV to perform control.
It mainly used to eliminate offset error during Pb control
Process value offset. Permits the user to offset the PV indication
from the actual PV
