In accordance with the Product Liability Act, the manufacturer of a product has an obligation to provide explanations and warnings as follows: The information given below must be understood in this respect. It is to advise the product user and protect him and his systems.

In case of destruction of the power components e. If such a situation occurs, then load voltages and currents are produced from the power circuit. It must be ensured by system design that no uncontrolled large currents, voltages or power occur. Malfunction and the results With malfunction it is possible that power, voltage or flow levels which are higher than planned reach the Thyristor Power Controller or load.

In principle, this can lead to the Power Controller or load being damaged. Transport Thyristor Power Controllers are only to be transported in their original packaging protection against damage e.

Installation If the Thyristor Power Controller is brought into the operation room from a cold environment, moisture due to condensation can occur. Prior to it being commissioned, the Thyristor Power Controller must be absolutely dry. Therefore, wait for a minimum of two hours before commissioning.

Connection Prior to connection, it must be ensured that the voltage information on the type plate corresponds with the mains voltage. The voltage-free state is to be determined by means of suitable measuring instruments.

This work is only to be carried out by a skilled electrician. The electrical regulations which are locally valid are to be adhered to. Repairs may only be carried out by qualified and trained maintenance personnel. Even after disconnection from the mains voltage, capacitors may still contain a dangerously high power level. Even when the Thyristor Power Controller is not triggered, the load circuit is not disconnected from the mains. Approvals and conformities Addresses 60 List of illustrations and tables Fig.

Introduction Thyro-A has been conceived to meet the demands for simple assembly, speedier commissioning and safer operation. For transport, assembly, installation, commissioning, operation and decommissioning, it is essential that the safety instructions included in these operating instructions are observed and made available to all persons handling this product.

In case of uncertainties or missing information, please contact your supplier. The described operating mode QTM is in preparation. It will also simply be referred to as Power Controller or Controller. It can be used wherever voltages or currents need ghyro-a be controlled or regulated in processing technology. Coupling to different bus systems, e. Thyro-A 1A Thyristor controller with single phase power section suited for single phase loads Thyro-A 2A Thyristor controller with double phase power section suited for symmetrical loads in three phase operation in three phase saver circuit Example Thyro-A 1A Thyristor controller with single phase power section Functions To enable Thyro-A to adjust optimally to the desired application, it is equipped with a wide range of functions.

These are described awg. Further functions are possible by applying Thyro-A within a bus system. In this operating mode almost no harmonics are created.

Whole multiples of the mains periods are switched, thus avoiding d. The full wave switch mode is especially suited for loads with thermal inertia. Depending on the function angle 1. Should there be a flicker, this can be minimized with the aid of the mains load optimization. Phase-angle principle VAR for 1A Depending on the prescribed set point, the sine oscillation of the mains voltage is gated using a larger or smaller control angle. thtro-a

This operating mode is characterized by high control dynamics. With phase-angle control harmonics of the mains voltage occur. It is possible to compensate these by using circuit variants. Depending on the prescribed set point, mains half waves are switched. The fast phase control is particularly suited for IR beams as an alternative to phase-angle control.

When using several controllers it is possible, by synchronisation, to keep the mains reactions small. All signals customary on the market may be used. The adaption is made by changing the starting and ending points of the control characteristic. Input set points The Power Controller Thyro-A is equipped with two input set points which are isolated from the mains, of which only one is always active. The following signal ranges can be set: Within the stated input ranges these values with the control characteristic may be adjusted to any common signal characteristic.

H RLP with additional P-control. Mains voltage variations and load changes are directly and quickly adjusted by bypassing the sluggish temperature control system. Before commissioning the Power Controller and selecting a control mode, familiarisation with the operating procedure and the effect upon the application is important. Activation of the integrated semiconductor fuse can be signalled using the K1 fault indicating relay undercurrent detection.

This has a relay. The following table shows the configuration of the corresponding terminals. Alarm relay K1 Root X3.

This produces the following absolute limiting values: If the undervoltage limit is undercut, the pulse lock is activated internally and relay K1 is released. The value is set by potentiometer R During the setting procedure an instrument connected to the analog output indicates the monitoring value.

Generally, the effective current value measured is continuously compared with a presettable absolute current limit for undercurrent. If this limit is undercut, an indication shows. In the case of resistance elements arranged in parallel, it htyro-a possible to select a partial load interruption by setting the undercurrent limit accordingly.

The temperature of the heat sink is measured.


In case of a temperature overrange a fault indication ensues and relay K1 ae default settings. Different variations can be realized depending on the requirements.

In case of malfunctions on the bus line, the set point value will be taken automatically from the Power Controller analog input, as ag in Chapter 3. It is thus possible to perform additional application functions. The data, which can be accessed via the bus module, is specified in the corresponding bus module operating instructions.

In order to achieve a narrower line width with a line recorder the output signal can be smoothed as required. As a aev, the time up to the initial switch-on varies. This makes staggered switching possible, particularly with the thuro-a pulse time of 1 sec. Values with an interval of mean a delayed switch-on by one pulse period T0 group formation. This function also allows switch-on to, for instance, an emergency power generator step-by-step switch-on of the load.
