Proper Use The GAMMAcast detectors are used in connection with a suitable evaluation unit (EVU) provided by Berthold and a corresponding source of radiation in order to measure the radiation intensity occurring during a radiometric measurement. The following constitutes proper use: •...
• If the GAMMAcast detectors are used in a way which is not described in the present operating manual, the warranty will be void. • Berthold only accepts liability for and/or guarantees the compliance of the GAMMAcast detectors with their published specifications.
Authorised Persons Authorised persons are those who are either designated for the corresponding task due to legal regulations or have been approved by Berthold for certain activities. Operator's Obligations The operator of the product must regularly train his personnel in the following topics: •...
GAMMAcast Detectors 3 Product Description Product Description The GAMMAcast detectors convert the Gamma-rays emitted by a source of radia- tion into electrical impulses. The pulse rate emitted at the output of the GAM- MAcast detectors to the evaluation unit is proportional to the impinging radiation intensity.

4 Commissioning GAMMAcast Detectors Water Cooling System Connection The GAMMAcast detector LB 6752 is already provided with a water cooling system upon delivery. The GAMMAcast detectors LB 6739 and LB 6760 can be purchased with an optional water cooling system. NOTICE Please make sure that the water is drained at the highest point, as shown in (Fig.5, item 3 and Fig.6, item 4).

4 Commissioning GAMMAcast Detectors Minimum Cooling Water Requirement NOTICE Device damage due to high temperatures! If the cooling water flow is shut off to early after end of casting, the admissi- ble temperature of the GAMMAcast detector may be exceeded. If the water is left in the water cooling system when there is a risk of frost, this may cause mechanical damage to the water cooling system.
GAMMAcast Detectors 5 Software Software In order to be able to access all functions of the GAMMAcast detectors, it is re- quired to operate the detector via the EVU LB 452, that enables the use of a soft- ware control. When operating the detector with another EVU, such as the LB 352, a detector software modem can be used in connection with a PC in order to access the soft- ware of the detector.
Install the drivers by executing the driver file "BertholdRS485.exe" before con- necting the detector service modem. The software can be downloaded from the Berthold website (www.berthold.com). Execute the installation file "Setup.exe" in order to install the operating soft- ware "LB 67xx PC control".
