Outline
ECS HV control of the ECAL and HCAL.
ECS HV control of the PS and SPD.

ECS CALO HV ControlThe ECS CALO HV control projects have been developed in close contact with the
LHCb Online group. There are two type of the projects. One is for ECAL/HCAL and second for PS/SPD.
Current projects allow:
1. Work within the LHCb FSM hierarchy.
2. Set HV for individual PMT or a group of PMTs;
3. Set HV for all detector channels with a desirable ramp time factor;
4. Fast emergency HV OFF;
5. Monitor :
a) HV control signals, and produce the warnings in case if the set and read values are different more than 1%;
b) 100 V and LV power supplies status for group of PMT’s, and produce the errors if values are out of the limits;
6. There are many possibility to create the recipes and there is a connection to CALO specific database.
7. The standard recipes for PHYSICS and COSMICS runs under preparation now.CALO Piquet Training Session 26.06.08 Anatoli Konoplyannikov /ITEP/
