GRB Feed Environmental Status
Figure 28 - GRB Feed Environmental Status Screenshot
Feed Tmp 33 Hum 31:
the internal temperature (in C) and humidity (in %)
of the GRB Feed
Press 0.0:
the internal pressure of the GRB Feed in PSI, should nominally be
0.25 psi
Purge OP:
the status of the GRB Feed Purge Valve, OP – OPEN or CL –
Closed
This display is useful to discover problems with the environmental controls and
pressurization of the GRB Feed. If the GRB Feed humidity is higher than 20%
or the dew point is within 10 degrees C of the temperature, the purge valve will
open to admit dry air. The purge valve will close when the GRB Feed
environment is OK.
When the purge valve is open, the pressure reading will not be accurate.
