BBL3 - Expert Information

BST (and some CST) signals are driving the following BBL3 channels (see BBL3 rack: second level of trailer, aisle 2, first rack):

   - Crate 0  Card 0  Channel 8:   #8 ...power_bst_strip
   -          Card 1  Channel 3:      ...hv­power­cst
   -                  Channel 15: #31 ...power_bst_pad
   - Crate 1  Card 2  Channel 9:  #41 ...bst_voltage_stat_strip
   -                  Channel 14: #46 ...bst_voltage_stat_pad
   -                  Channel 15:     ...cst_voltage_stat
   - Crate 2  Card 0  Channel 12:     ...water_bst_temperature
   -                  Channel 13:     ...water_bst_flow
   -                  Channel 14:     ...water_bst_watchdog
   - Crate 2  Card 1  Channel 15:     ...rad_level

The BST related alarms are steered by a digital I/O module in the BST Slow Control Crate and enter the BBL3 system in the relay station in rack E5 (first level of trailer).

signal	slow control tag	digital I/O pair	cable to & input at E5	CDAQ console LED	BBL3 alert	comment
...power_bst_pad	BBL3_ST_0	1-2	4 --> 6		alarm
...power_bst_strip	BBL3_ST_1	3-4	8 --> 9		alarm
...bst_voltage_stat_pad	BBL3_ST_2	5-62	13 --> 18	x	warning	shortcut at the switchpanel in rack B10 while BST Pad Detector is off by default
...bst_voltage_stat_strip	BBL3_ST_3	7-8	14 --> 20	x	warning

A BBL3 cabling panel is in the rear of the BST Slow Control Crate (first level of trailer, aisle B, rack 10, second crate from bottom). Underneath a 4-channel fanout box a screw board is used to connect between different kinds of cables. This picture shows connections and cable labels as well as their source and destination.
