1-4-4 Control Circuit
Control Circuit Wiring
The control signals are connected by screws. The following figure
shows the relationship between I/O signals (factory preset values)
and screw terminal numbers. The terminal functions shown in the
figure indicate standard setting prior to shipping. Since Operation
Mode from the Digital Operator is set for the Model with the Digital
Operator, it is necessary to change the control constants when
operation is performed from the control circuit terminals. For
details, refer to
2-8-2 Operation Mode Selection
