Control system (S1-1)
[Function]
This makes a selection of phase control or cycle control. The phase control is to control the
phase of half-cycle by means of its effective value.
The cycle control is to control the number of turning ON in one cycle during a certain con-
stant period by means of its effective value. Changeover between phase and cycle controls
is not possible during output operation. Changeover between phase and cycle controls is
possible only while the power is turned off.
Use the S1-4 switches to change the setting of intermittent type/continuous type for cycle
control. However, changeover of the control system is not made during output operation.
A system is provided to prevent the changeover of control system during its operation.
Type of temperature control unit (S1-2, 3)
[Function]
This changes the signal levels sent from the temperature control unit, and selects the two-
position control. Changeover of the operating conditions of temperature control unit is pos-
sible only while the power is at a standstill, but such changeover is not possible during out-
put operation.
However, changeover of the type of the temperature control unit is not possible during out-
put operation. A system is provided to prevent the changeover of the type of temperature
control unit during operation.
Cycle control (S1-4)
[Function]
This makes a selection of intermittent type or continuous type for cycle control.
Use the S1-1 switch to change the setting of phase control or cycle control.
However, changeover of the cycle control is not possible during output operation. A system
is provided to prevent the changeover of cycle control during output operation.
Setting of dip switch S3
S3 is a switch to change the setting of the unit address when an optional RS485 communication unit is
installed. Therefore, leave the setting of the switch as initially set.
