3.2.7.2 Clean air protection.
Not applicable.
3.2.7.3 Electrical power protection,
Applicable.
3.2.7.3.1 Emergency shutdown switch. An emergency shutdown switch shall
be provided for use by the operator. When the emergency shutdown switch is
activated the load side of all LC primary circuit breakers shall be dis-
connected from their respective loads. The switch utilized for this appli-
cation shall be of the pushbutton activated, momentary type with the push-
button finished in red. The front panel area around the pushbutton shall
be marked with alternating orange-yellow and black stripes. The switch
shall be centrally located on the external control panel of the LC in an
area which is easily accessible to the operator during normal operation.
3.2,8 Calibration cycle. Applicable.
3.2.9 Power switching and coolant control. The LC shall provide the
necessary switching and hydraulic devices to control utility power forms,
liquid coolant and potable water.
3.2.10 Displays. Displays provided on the cabinet assembly and on the
remote switching control shall provide an indication of LC operational
status.
3.2.11 Installation. The LC shall be capable of supplying coolant to
Test Station, Radio Frequency OJ-213( )/AWM-23(V) Test Station, Low
Frequency OJ-215( )/AWM-23(V) and OJ-379( )/AWM-23(V) and Stand, Fill-Drain,
Coolant System MT-4730( )/AWM-23(V) as follows:
a.
A maximum of 30 psi drop in the supply and return lines as
a closed loop.
No vertical head difference between the LC and the test
b.
stations.
3.3 Performance.
3.3.1 General.
The LC shall provide liquid cooling with the following
parameters:
a.
Supply pressure. Pressure of the coolant at the output of
the LC shall be ajustable between 150 and 95 psig and shall
psig of the setting. Pressure shall be
be accurate to
maintained within
psi for any flow between 1 and 13 gpm
output of the unit.
b.
Total heat load. The LC shall have the capacity to remove
a maximum heat load of 80,000 British thermal units per hour
(Btu/hour) at a coolant flow of 8 gpm, and 13,000 Btu/hour
at a coolant flow of 1.3 gpm.
c.
Coolant temperature. Input to LC SO to 125F
+ 20F
Output of LC 65
-15F
d.
Particulate filtration. 10 microns absolute, full flow
e.
Reconditioning filtration. See 3.4.3
