FGD1 Water Temperature monitoring

1

Documentation for FGD1 Water temperature moinoting through MSCB

Purpose

Monitor the temperature of the 2 water loops of the FGD1.

Description

• The MSCB interface reads back the inlet and outlet water temperature of the loop1 (first loop in the beam direction) and loop2.

Card Operation

• The SMCB node can be contacted through the MSCB506(n35/g77).
• The frontend fefgd1watertemp.c code handles the monitoring of these 4 variables. It resides on the t2kgsc0:online/gsc/fgd/
