Operation and Handling
Since the power consumption of transmitting tubes is generally high, the voltages applied to each electrodes are high and the temperature of the electrodes rises accordingly.Therefore, incorrect operation may result in personal injury.In addi-tion, it is difficult to determine the mechanical design strength of a transmitting tube from its external appearance.
Therefore, all personnel who work with transmitting tubes must have a thorough understanding of correct operating pro-cedures to prevent damage and must handle such tubes with extreme care.
System designers and personnel involved in performing work are responsible for ensuring worker safety.
1.Applications and objectives
This product is intended for use in industrial equipment only.It is not to be sold to or used by the general pub-lic.
This product is not designed or intended for use in combination with equipment in which malfunction or incor-rect operation could lead to personal injury or death, Such use is strictly prohibited.
Refer to delivery specifications and engineering information issued by Toshiba to ensure safe operation of this product.
Store this product in a dry location (relative humidity < 60 %).Do not store this product in a location where the temperature or humidity may change rapidly because condensation may form on the surface of the product.
A filter should be used because accumulated dust will lead to deterioration of withstand voltage and may gen-erate smoke or catch fire.
3.Precaution against incorrect or inappropriate operation
If this product is operated with an excessively high voltage or current, X-rays exceeding the standard may be generated.Never use this product with a voltage or current exceeding the rated values.
Prior consultation with Toshiba is required if this product is to be used under conditions other than those speci-fied or if it is used for a new type of equipment.
Before using this product, determine whether or not it can be used for industrial heating applications.
4.Only qualified engineers are permitted to use, assemble, maintain, or check this product.Other personnel are prohibited from handling this product.
4.1 Precautions for operation and maintenance
To ensure that the end user is aware of the safety precautions, include the descriptions given in the safety precau-tions in the operations manual provided with the equipment or take other appropriate actions.
4.2 High voltage
The voltage applied to the electrodes of the power tube can exceed 10kV, which is deadly, and the equipment must be designed properly and operating precautions must be followed.
5.Safety features to be incorporated in the design
*The following safety features should be incorporated in the system design:
The equipment must be designed to prevent personnel from coming into contact with high circuit.*Interlock switches must be provided on access doors, so that when these are opened for inspection or re-placement of the tube, power supply is turned off and high-voltage capacitors are discharged.
*The power supply cannot be turned on again unless the access boor is fully closed.
5.1Safety precautions for inspection and replacement to tube
It is preferable to request that the system manufacturer send an engineer to inspect and replace the tube;If this is not possible, two or more qualified persons well-trained in electrical work can perform the inspection and replacement.In either case, all power supplies must be turned off before beginning any service proce-dure, and parts being inspected or replaced must be grounded with aground bar.
5.2 High temperature
Although a cooling system is used, the electrode terminals are very hot both during and after operation.Do not touch the tube just after turn off the power;Wait until the temperature decreases enough not to be dangerous.
