2   General Information

2.1  General Information

This manual is intended to assist users in the operation of the Releases 012, 013, 022, 023 and 042 in 
sub-releases 10, 85 and E8 of the SC-TDC-1000 S series. It is divided into 6 chapters. The chapter “General 
Information” contains a brief overview of the devices as well as the safety instructions. The chapter 
“Installation” refers to installation and cabling. The other chapters contain amongst others technical details 
and the description of the device layout.

2.2  Safety Instructions

The “caution symbol” marks warnings, which are given to prevent an accidental damaging 

of the detector or the readout system. Do NOT ignore these warnings and follow them 

strictly. Otherwise no guarantee is given for arose damages.

Note

The “note symbol” marks text passages, which contain important information/hints 

about  the  operation  of  the  detector.  Follow  these  information  to  ensure  a  proper                            

functioning of the detector.

The “high voltage symbol” marks warnings, given in conjunction with the description of 

the operation/use of high voltage supplies and/or high voltage conducting parts.

Hazardous voltages are present, which can cause serious or fatal injuries. Therefore 

only persons with the appropriate training are allowed to carry out the installation, 

adjustment and repair work.

Please read this manual carefully before performing any electrical or electronic operations and strictly 

follow the safety rules given within this manual. Surface Concept declines all responsibility for damages 

or injuries caused by an improper use of the module due to negligence on behalf of the User.

The following symbols may appear throughout the manual:
