Usage : GLFRIG is the Java Open Access Client (OAC) process which
provides global frig control and mass flow calculation devices.
You can view log files for GLFRIG in the directory
'daesrv\\engines\files\oac'.
Restart: GLFRIG is restarted when its DAE is restarted.

Usage : GLFRIG is the set of global frig intelligence processes.
Right now it comprises 2 of them:
1. Mass flow calculations based on the helium library,
calculating flow in grams per second.
2. Cold compressor control for low betta quenches. It waits
for the event 5E to occur and then checks quench conditions on
B0 and D0 QPMs. If they are met, cold compressors will be switched
of in the appropriate FRIG houses (A4 and B1 for B0 QPM and C4
and D1 for D0 QPM).
Log file is located at op$usr1:[vaxappl.oaf.glfrig].
Restart: GLFRIG is restarted on an ACNET boot of CDAS. Using the
Operator account on CDAS, a restart may be done with
'ACNET RESTART GLFRIG'.
Errors: A (-1) is returned for both dio read errors and errors
in calculating devices. Errors are written to an error log
"GLFRIGLG". Use D112 LOGTEST to access GLFRIGLG error log.
Inputs: See "F75 Helium Flows" for Input Device Names.
Each Mass Flow Meter has three input devices: flow, pressure
temperature. Device Indices are stored in two FileShare files.
Compressors: RSX$FHARE_APPLICAT_TEVATRON_FRIG:F74COMP.SAV
Refrigerators: RSX$FHARE_APPLICAT_TEVATRON_FRIG:F74FRIG.SAV
"D75 Helium Flows" can be used to change input devices for both
"F75 Helium Flows" and "GLFRIG OAF" devices. Changes
show up in FileShare F74COMP.SAV abd F74FRIG.SAV Which can
be viewed from D50 FSDUMP.Select "Decimal*4" to read files.
Flow, Pressure and Temperature
devices are entered as Device Indices in the order of
flow, pressure, temperature.
F74COMP.SAV has 1 valid record with 60 input devices for
twenty Mass Flow Devices at ten Compressor houses.
F74FRIG.SAV valid records 2 through 29.
First field in each record is the record number followed
by eighteen devices, three each for six Mass Flow Devices
in each refrigerator house.
BR record 26 has four Mass Flow Devices.
LB and RB records 27 and 28 have three Mass Flow Devices each.
PR record 29 has one Mass Flow Device.
