THREE-pHASE pRIMARY iNTERLOCK sWITCH
Primary interlock switches are used in radiation protection rooms and cabinets to interrupt the primary power supply to the x-ray radiating unit when access doors or flaps are opened under normal operating conditions. The interlock circuits are physically linked to the doors and flaps.
This primary interlock switch has two components, which are designed so that only one needs to be wired. When the switch is opened, it directly interrupts the primary current circuit for the x-ray unit. An additional internal switch can send status messages to the control unit.

X-Ray Warning Flash Lamp with "fail-safe circuit"
When x-rays are being generated from an x-ray tube there must be a clear and safe indication of this hazardous condition. All Seifert controls are equipped with multiple warning facilities, including the "High Voltage ON" indication lamp on the control panel.
While other external warning lamps might fail due to a defective bulb or other reasons, this "High Voltage ON" lamp is connected in a fail-safe circuit causing the high voltage to be interrupted in the event of bulb burnout or other malfunction.
This has been a standard feature on all modern Seifert controls for over two decades.
The protection offered by the X-RAY WARNING FLASH LAMP with "FAIL-SAFE CIRCUIT" is now available in this external warning lamp, too, as required by DIN54113 and many other new safety standards. A built-in opto-electronic circuit monitors the function of the flash lamp. Should the bulb of the warning lamp cease to function for any reason, the circuit will interrupt the high voltage and the generation of x-rays.

Tripod Stand for X-Ray Tubes
The tripod stand was developed to support the x-ray tube housing at various inspection tasks (site inspection or similar). It allows a simple and quick alignment of the x-ray tube to various exposure positions.

Pipe Inspection Stand
The pipe inspection stand was developed to meet the specific requirements in welding seam inspection under extreme conditions. The stand is characterized by the following possibilities of positioning:
- Swiveling of the stand around the pipe to be inspected by shifting the strap (360°)
- Rotation of the tube housing in a clamp around its own longitudinal axis (360°)
- Rotation of the holding clamp around the stand pillar which is laterally displaced with regard to the pipe axis (360°)
- Rotation of the holding clamp around an axis at an right angle to the longitudinal tube housing axis (360°)
- Rotation of the holding clamp around the stand pillar when displaced toward the pipe direction (360°)
- Displacement of the holding clamp, vertically to the pipe axis

External kV Jogging Dial for ISOVOLT HS X-Ray Equipment
Usually the kV set point value of the ISOVOLT HS is pre-selected by using the keyboard of the control module. For some applications, however, it is more practical to change the kV value by simply turning a dial while viewing the radioscopic x-ray image. The external kV jogging dial serves this purpose. It enables a quasi-stepless kV set point value setting for the ISOVOLT HS. Produced under ISO 9001 certified quality management system.
The kV jogging dial is connected to one of the two RS232 serial interfaces of the ISOVOLT HS by a connecting cable. The interface selection depends on the local conditions. The kV jogging dial itself does not need any settings. If the kV jogging dial is to be connected to the control module the B-X2 plug-in connection must be used. V-X8 indicates the corresponding plug-in connection at the power module. The interface parameters of the ISOVOLT HS must correspond to the kV jogging dial parameters (see Technical Data). The setting procedure is described in the operating instructions of the ISOVOLT HS. A kV value is set by turning the dial. Turning it clockwise increases the kV value. Turning it counterclockwise will decrease it. If the connected x-ray tube has not been warmed up to the nominal voltage level the jogging dial cannot set the voltage above the warm-up limit. If the dial is turned further the ISOVOLT HS display will show the error message “Tube Warm-Up“. The high voltage remains activated. If the jogging dial is then turned counterclockwise the error message will be de-activated.
|KV Setting Range||5 kV to nominal voltage or to warm-up voltage of the X-Ray tube connected|
|Connecting Cable||2 m (6.4 ft) long, nine-pole SUB-D plug|
|Interface Parameters||1200 baud, 8 data bits, 1 stop bit, no parity|
