The silicon detectors are polarized by a CAEN SY527 system. It consists of a 19" wide crate, fitting several kind of low and high voltage boards. The same system also provides the low voltage for the preamplifiers.
The SY527 is remotely controlled via VME. The software to control the detector polarization has been realized using the Labview code. It is able to detect current overloads; in this case it reacts decreasing the polarization voltage to protect the silicon detectors against breakdown.
The software also provides the current and voltage monitor.
