EMC Monitoring Main Window
Dictionary (What the hell does that mean ??!!)
General Organization of the Epics Monitoring Screen.
EMB: Environment Monitoring
GMB: General Monitoring
Properly configured they are used to monitor temperatures (TMB) , Low Voltages
RMB: RadFet Monitoring
Board. Similar to the GMB it is used
in the EMC to read the radiation monitors (RadFet).
IOB: Input Output Board.
LV PS : Low Voltage
Fluor: Fluorinert Chiller cooling the crystal diodes and the electronics.
Water: The barrel calorimeter electronics is cooled by a water chiller
in addition to the fluorinert chiller .
TEMPS: stands for crystal temperatures.
TRB LV: Transmission Boards
NSOURCE: Neutron Source used for calibration ( activation of
the Fluorinert coolant ).
DIODE PS: Photodiodes Bias Voltage.
BF: Barrel Forward.
BB: Barrel Backward.
t.b.i ( to be implemented ).
Each button on the screen pops up another DISPLAY screen.
What is critical ?
The screen is divided in 4 colums corresponding to the 4 independant CAN
bus used read the GMBs.
1) CAN0 / BARREL BACKWARD (left column) is
reading the Barrel Backward EMBs, Low Voltage Power Supplies parameters,
Barrel Crystal Temperatures and Barrel RadFets.
2) CAN1 / BARREL FORWARD (2nd column starting
from the left) is reading Barrel Forward EMBs, Low Volatge
Power Supplies parameters and the Neutron Source parameters ( t.b.i.).
3) CAN2 / END CAP ( 3rd column starting
from the left) is reading EndCap EMBs, Low Volatge Power Supplies
Parameters, RadFets and temperatures.
4) CAN3 / GENERAL ( last column). Thhis one for the moment has
only one radFet under it's supervision. It will soon read the Chiller parameters
and Light pulser parameters.
The only safety critical Item is the EMC cooling. The SIAM interlock
systems takes care of
the survey of any Chiller problem which would induce overheating in
Who is in charge of this epics stuff ??
SIAM in normal operation the SIAM button is green. If it turns
red there is a hardware problem on the cooling system. push the button
and determine which sensor gave an alarm. The guidance on each SIAM epics
screen will help you resolve the problem.
