EXTERNAL CONNECTION DIAGRAM OF UNIT
Connection diagram for each setting system
Connection diagrams for each setting system are shown below.
Short circuit between GT and PH terminals during operation. Open-circuiting between them during
operation forcibly stops output.
Short-circuiting between ST and PH terminals starts output, and open-circuiting between them
stops output.
GT and ST terminals function differently in stop movement as listed below.
AT and PT terminals become automatic adjustment when short-circuited, and become manual
adjustment when open-circuited.
HL and PH terminals start output in case that the setting of an upper limit at short-circuit or of a
lower limit at open-circuit is made.
When GT and PH terminals are open-circuited, the GT terminal immediately stops output regard-
less of the soft start period.
When ST and PH terminals are open-circuited, the ST terminal gradually reduces output during the
soft start period, and finally stops output.
When GT and ST terminals are short-circuited, both terminals gradually increase output to its set
value during the soft start period.
Manual adjustment
The setting of Grade, Manual, and Lower Point is selectively available. The setting of Ratio, Upper Limit, and Lower Limit is selectively available.
The setting of Grade and Lower Point is selectively available. The setting of Grade and Lower Point is selectively available.

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.

DETECTION OF ABNORMALITY
Detection and indication of abnormality
In the event of any abnormality, check the Unit Abnormality lamp, stop operation of the unit, and
then turn off power.
When an abnormality detection circuit functions, an abnormality indication lamps lights up or flickers on
the right-hand side of the terminal block inside the front panel of the unit.
Abnormality indications, abnormality descriptions, operating status, and procedures to restart operation
are as listed below.
1 This abnormality is available only for an 100A unit or larger.
2 This abnormality is available only for an unit with fuse.
3 This abnormality is available only for an unit equipped with a conversion board for detection of
heater disconnection (optional).
OCR
This detects overcurrent when the current exceeding 150 percent of the unit’s rated current has flowed
over several cycles. On detection of overcurrent, an “OCR” indication lights up and operation stops. To
resume operation, turn off the control power supply.
TMP
This detects temperature rise abnormality when the temperature of a cooling fin has been increased
abnormally. On detection of temperature rise abnormality, a “TMP” indication lights up and operation
stops. To resume operation, turn off the control power supply.

F
This detects fuse disconnection when a fuse built in the unit (optional) is disconnected. On detection of
fuse disconnection, an “F” indication lights up and operation stops. To resume operation, turn off the
control power supply.
HET
The optional function is provided to detect heater disconnection. On detection of heater disconnection,
an “HET” indication lights up and operation continues.
THY
The self-diagnostic function is provided to detect Thyristor open or short. On detection of Thyristor
open or short, a “THY” indication flickers and operation stops. To resume operation, turn off the control
power supply.
LOD
The self-diagnostic function is provided to detect load open or short. On detection of load open or
short, an “LOD” indication flickers. Operation continues in the event of load open. Operation stops in
the event of load short. To resume operation, turn off the control power supply.
FRQ
This detects abnormal frequency in the event of any abnormality with frequency of control power sup-
ply. On detection of abnormal frequency, an “FRQ” indication flickers and operation continues.
L. Vo
This detects power supply undervoltage when the voltage of control power supply falls below its appro-
priate value. On detection of power supply undervoltage, an “L. Vo” indication flickers. Operation is at a
standstill only while such abnormality is detected. When the detection of abnormality is released, oper-
ation is automatically resumed.

15
Self-diagnostic function
This function is provided somewhat differently depending on the combination with a conversion board
(optional).
Only when conversion boards 3 (U) and 3H (U) mounted.
The item marked with is judged to be load short even in the case of Thyristor open.
Starting the unit without turning on the power of main circuit for test operation may cause its self-diag-
nostic function to stop operation. In such a case, release the self-diagnostic function once to restart
operation.
To forcibly release the self-diagnostic function, use a thin bar-shaped item to press the SELF CHECK
switch located on the lower-right part after opening a terminal cover on the front of the unit. When the
switch for approximately one second is pressed, the abnormality indication lamps of “THY” and “LOD”
on the upper part simultaneously flicker for about 1 minute. If the control power supply is turned off and
then on during compulsory release of self-diagnostic function, the settings are stored during such com-
pulsory release. When the control power supply is turned on, the abnormality indication lamps of “THY”
and “LOD” flicker for about 1 minute simultaneously, indicating that the self diagnostic function is in
compulsory release.
To recover the self-diagnostic function, press the SELF CHECK switch again. Doing so causes such
abnormality indication lamps to go out in the case they are flickering simultaneously.

External warning circuit
The abnormality detection circuit, when activates, causes an external warning relay in the unit to acti-
vate. Major and minor failure relays are provided as the external warning relay.
Major failure relay
The abnormalities described below, when detected, forcibly stops operation and at the same time
causes a major failure relay in the unit to activate.
Detection of overcurrent
Temperature rise abnormality
Fuse disconnection
Thyristor open/short and load short to be detected by self-diagnosis function
Use the output of the major failure relay contact to monitor any abnormality.
The output of the major failure relay contact informs multiple abnormalities detected. So, check the indi-
cation of abnormality detection to know what abnormality was detected as a cause of activating the
relay.
Minor failure relay
The abnormalities listed below, when detected, causes a minor failure relay in the unit to activate.
Power supply undervoltage
Abnormal frequency
Load open to be detected by self-diagnostic function
Detection of heater disconnection (optional)
There may be the cases that power supply undervoltage and abnormal frequency are detected when
the control power supply is turned on/off. Therefore, the relay does not activate for about 3 seconds
after detection of such abnormalities even when they are actually detected.
Use the output of the minor failure relay contact to monitor any abnormality.
The output of the minor failure relay contact informs multiple abnormalities detected. So, check the indi-
cation of abnormality detection to know what abnormality was detected as a cause of activating the
relay.
