Description:
TTS (Tube Temperature Supervision): Tube Supervision Error from FU kV; thermal switch of tube housing okay?
Possible Causes / Advice:
Short to ground, signal noise from any source at tube housing thermal switch signal EZX3 / EWGX8 / EWGX9 pins 3-4 backpanel version 4512 108 05983 pins 6-7 backpanel versions 4512 108 05984 + 4512 108 09361 Remove cable connection and insert a decade plug with a short link pins 3-4 or 6-7 instead to simulate the tube housing contact, see if problem disappears, if not measure signal TH_OL_SW/ at EZ130 X1:A11 Short to ground at signal TH_OL EZ130 X1:A12. This signal is not used in any system as a thermal tube sensor is not available yet. This problem might be caused by a non-screened stator & thermal switch cables. 0722-215-02054 (3 x 1.31mm screened stator cable) 4512-100-66151 (2 wire screened cable for thermal switch) With a PC and XRGSCOPE: go path >Select Unit > FU-kV > FU-kV > Faultfind > Monitoring > Measure Temperatures > tube temp switch: should be closed = ok will have short circuit =00TB can be = open if connection removed
