5. WIRING

To prevent electric shock or instrument failure, do not turn on the power until all wiring is completed. Make sure that the wiring is correct before applying power to the instrument.

5.1 Wiring of Main Circuit

CAUTION

Always conduct wiring so that the phase of the main circuit (2/T1) coincides with that of terminal No. 4 and the

phase of the main circuit (1/L1), with that of terminal No. 5. Otherwise the instrument may not function properly or the load may be damaged.

Caution for connecting a transformer to the load side of the instrument

When a protection function for control of primary side of a transformer is provided:

To conduct control of primary side of a transformer, make sure protection function for control of primary side of a control is set. Appropriately adjust the soft-start time for in case of secondary side breakdown depending on the operating condition.

When a protection function for control of primary side of a transformer is not provided:

If the action of the device is influenced by excessive current (inrush current, current due to flux saturation of transformer), use a transformer 1.25 T (magnetic flux density) or less. Make sure soft-start time is appropriately set.

When connecting a transformer to the load side of this product, make sure that the current value of the primary side of the transformer is equal to or more than the minimum load current of this product. When the current value of the primary side of the transformer is less than the minimum load current value of this product, connect a bleeder resistor in parallel with the primary side of the transformer, and allow the current more than the minimum load current to flow. Minimum load current: 0.6 A (20 A type) 1 A (30 A type or more)

When control is started on this instrument without connecting a load to the transformer, it may result in heat generation or failure of the transformer. Control must be always conducted with the load connected.

Caution for connecting a noise filter to the load side of the instrument

When the control of this instrument is started without connecting a load in a configuration where a noise filter is connected to the load side of the instrument, a large surge may occur to the noise filter and a damage of the instrument may result. Control must be always conducted with the load connected.

THV-1 conforms to CE marking by using the noise filter.

If a load generating large rush current is used, thyristor break-down may occur when no soft-start time is appropriately set. Also in Zero-cross control, no rush current can be suppressed even if the soft-start time is set.

If the protection function for control of primary side of a transformer is enabled, soft-start function is always operated for 0.1

second regardless of setting of soft-start time (U) at 0.0 seconds.

Output limiter high value must be equal or higher than Output limiter low.

These function can not be used together.

Base-up set value will not exceed the Output limiter high.

The Output mode setting is invalid when the Control method is Zero-cross control.

These parameters cannot be set when the Heater break alarm, Current limiter, Constant current control and Protection function for control of primary side of a transformer functions are not provided. If the rated current of thyristor differs from that maximum load current flowing through the heater when the Constant current control is selected, compensate for the difference by setting the gradient. Set the gradient so that the maximum heater load current will flow through the heater at an input signal of 100 % from the controller. (Refer to P. 19)

2. The input signal from controller is displayed when the contact is open. The Internal manual set value is displayed when the contact is closed.

7.2 Control Method

Phase control

Phase control is to continuously control electric power supplied to a load by changing phase angle of AC voltage applied to the load. Each half-cycle has ON and OFF time.

Zero-cross control (Continuous)

Continuous Zero-cross control is to control electric power supplied to a load by turning the power supply voltage ON and OFF at the point of 0 V AC so that the high frequency noise can be suppressed compared with Phase control. This on and off time is typically measured in milliseconds.

Zero-cross control (Input synchronous type)

Input Synchronous type Zero-cross control is to turn the power supply ON and OFF synchronously with the pulse signal from a controller. This on and off time is typically measured in seconds.

7.3 Ramp Function (Soft-Start/Soft-Down Function)

Soft-start/Soft-down function gradually ramps up/down the output voltage to the demand level over the set time to prevent a sudden change in load or voltage. The Soft-start/Soft-down time sets a period of time from 0 to 100 % or 100 to 0 %.

7.4 Gradient Setting Function

Gradient setting is a multiplier to be applied to output to the load to adjust the output value depending on an application.

The following two types of gradient setting are available.

Internal gradient setting set by the THV-1 front keys External gradient setting set by the external gradient setter

(external potentiometer) The output value is adjusted by Gradient setting function as follows.

(Output voltage computed by Auto mode) (Internal gradient

setting) (External gradient set value)

(Output voltage computed by Auto mode) (Internal gradient

set value)

(Output by manual set value) (Internal gradient set value)

(External gradient set value)

If it is necessary to make only the External gradient set value valid, set the Internal gradient set value to 1.00.

Constant current control

This is the function used to keep the output current constant in proportion to the input signal. This function is effective when a heater with large resistance changes caused by temperature variations is used (such as tantalum, superkanthal, tungsten, platinum, or molybdenum). The maximum output current when the Constant current control function is used coincides with the rated current in the thyristor specification.

Operating condition Stability

Power supply voltage variation 10 % Load variation 2 times

Caution for using Constant current control function

If the rated current of thyristor differs from that maximum load current flowing through the heater, compensate for the difference by setting the gradient. If there is the difference, a section where control is disabled may come into existence. A compensation example when there is a difference between the currents flowing through the thyristor and the heater is shown in the following.

Example: When used in the following condition

Rated current of Thyristor: 30 A Input signal from controller: 4 to 20 mA DC Maximum load current of heater: 15 A Soft-start time setting: 0.0 seconds

The Soft-start function is activated during four cycles from load operation start even at a Soft-start time of 0.0 seconds.

When used without setting the gradient, the maximum heater load current becomes 15 A at an input signal of 12 mA. In this case, control is disabled if the input signal exceeds 12 mA.

7.8 Automatic Power Frequency Detection and Power Frequency Monitoring Function

Automatic power frequency detection

The instrument automatically detects a power supply frequency (50 Hz or 60 Hz) when the power is turned on. Displays Error number 32 (Power frequency error 2) at the Error display when failed to detect Power supply frequency.

Power frequency monitoring function

This function monitors the power supply frequency and when it goes out of the detection range, the error message display appears. Displays Error number 16 (Power frequency error 1). To confirm power supply frequency, switch to the Power frequency monitor by pressing the Parameter key at the Error display. (Only Power frequency monitor is available.)

Detection range: 50 Hz = 45.0 to 54.9 Hz

Error message will be cleared when power supply frequency returns to the detection range during the operation.

60 Hz = 55.0 to 64.9 Hz

7.9 Heater Break Alarm Function

The Heater break alarm monitors the current flowing through the load by a dedicated current transformer (CT). The THV compares the measured value with the set values, and detects a fault in the heating or cooling circuit. In addition, there are several types of Heater break alarms depending on control methods and applications of these Heater break alarms. Read this chapter carefully to choose an suitable method and set an appropriate set value.

7.9.1 Common function for all types

Number of alarm delay times

To prevent producing a false alarm, the alarm function waits to produce an alarm status until the measured current by the CT is in an alarm range for the preset number of consecutive sampling cycles. The parameter of the Number of alarm delay times is to change the number of consecutive sampling cycles by 5-cycle increment.

Heater break alarm 1: (5 cycles) (Number of alarm delay times) Heater break alarm 2: (5 cycles) (Number of alarm delay times) 10

7.9.2 Heater break alarm for Phase control

There are two alarm types (type 1 or type 2) available for Phase control.

(1) Type 1

Type 1 can be used as follows by using two Heater break alarm set values. (Refer to Application)

Heater break alarm 1 set value: The alarm can be output when a heater break occurs by setting the Heater break alarm set value. Heater break alarm 2 set value: This alarm set value can be used as an auxiliary alarm. For example, it can be used as a

The Heater break alarm of Type 1 cannot be used for heat generation substances such as noble metals making

large resistance changes with temperature variations. In addition, it cannot be used for heat generation substances such as silicon carbide making resistance changes with temperature variations and a lapse of time.

Type 1 cannot be used for any power supply waveforms other than a sine waveform.

How alarm is activated

When heater current does not flow (Heater break, malfunction of the control device, etc.)

When the phase angle is equal to or more than 15% and the current transformer input value is equal to or less than the Heater break alarm set value for the preset number of consecutive sampling cycles, an alarm status is produced.

However, in order to prevent malfunctioning, it is so designed that no Heater break alarm occurs at an phase angle of less than 15 % (less than 15 % of maximum load current).

When heater current can not be turned off (Thyristor break-down or permanent damage)

When the current transformer input value is equal to or greater than the Heater break alarm set value for the preset number of consecutive sampling cycles, an alarm status is produced.

The alarm will be turned off when the current transformer input value goes in and stays at non-alarm range for five consecutive cycles.

Application (When Heater break alarm 1 is used for detecting any broken heater or Heater break alarm 2,

for detecting any deteriorated heater.)

Refer to the figure below for action by setting the set values for the following parameters:

7.10 Current Limiter Function

This is the function of limiting a measured current value to a value not exceeding the preset current limit value. A current value is measured for each constant cycle and then the maximum phase angle not exceeding the Current limit value is computed from the above current value thus measured. If the phase angle at that current output is larger than the maximum phase angle computed, the current is output at the maximum phase angle to restrict that current. The maximum phase angle is computed during a time period of 0.1 seconds from the start of load operation, and the Current limit function is activated after the maximum phase angle is computed.

Even at a Soft-start time of 0.0 seconds, the Soft-start function is activated in order to compute the maximum phase angle during a time period of 0.1 seconds from the start of load operation.

If a current value exceeds Current limit value + Differential gap (0.5 A or 1 A) * due to voltage variations or load resistance changes while the Current limit function is being activated, the maximum phase angle is immediately re-computed to restrict it within a cycle of 2.5 from the time when it exceeds Current limit value + Differential gap.

* Differential gap 0.5 A: 20 A, 30 A types

Differential gap 1 A: 45 A, 60 A, 80 A and 100 A types

If a Current limit value is set to its maximum value, the Current limit function is deactivated.

The Current limiter function cannot be used when Zero-cross control is selected.

7.12 Protection Function for Control of Primary Side of a Transformer

If momentary power failure occurs during execution of the control of primary side of a transformer, inrush current is generated. Protection function for control of primary side of a transformer is to protect the thyristor from the inrush current. With this protection function enabled, when momentary power failure occurs, the instrument determines that the secondary side of a transformer was disconnected and suppresses the output. When the instrument is automatically reset from the breakdown (momentary power failure), the soft-start function suppresses the inrush current. To use this protection, the following parameters need to be set.

Protection function for control of primary side of a transformer (t)

Determination set value in case of a break on the secondary side of the transformer (a)

Output limiter setting in case of a break on the secondary side of the transformer (h)

Soft-start time in case of break on the secondary side of the transformer (u)

While control of primary side of a transformer is executed, if the current transformer (CT) value goes below the determination set value in case of a break on the secondary side of the transformer, it is judged to be a break (momentary power failure). Below is a formula to convert the determination set value in case of a break on the secondary side of the transformer (a) into the current value (A).

While the phase angle is 20 % or more, when the current goes over the determination set value in case of a break on the secondary side of the transformer by 0.3 A (instrument of 45 A or more: 1 A), it is judged to be a release from a break (momentary power failure).

Soft-start function in case of break on the secondary side of the transformer

This is a soft-start function which is activated when the instrument is automatically released from the break (momentary power failure) of the secondary side of the transformer. This function suppresses the inrush current at the time of automatic release from the break (momentary power failure).

While the soft-start function of the soft-start time (U) is working, if break (momentary power failure) of secondary side of a transformer occurs, protection function for control of primary side of a transformer starts working to suppress the output. When released from the break (momentary power failure), the instrument changes the output according to the soft-start time in case of break on the secondary side of the transformer (u). After elapse of the soft-start time in case of break on the secondary side of the transformer (u), the soft-start time (U) takes over, and output is changed in the remaining time of the soft-start time (U).
