CC-11 Front Panel Controls / Functions
A. Pump Pressure Gage:
This is the delivery pressure at the supply fitting . The
delivery pressure is set at the factory in the range of
170 to 175 psig at 1 .5 gpm (11 . 7 to 12 . 1 bar at 5 . 7 l/min . ) .
Lower flows will result in higher pressure readings;
higher flows will result in lower pressure readings .
The pressure is set with a back pressure regulator
located near the coolant reservoir . It should not be
necessary to readjust the pressure setting in the field,
unless the back pressure regulator is replaced or un
less the CC11 is used in an application requiring low
er delivery pressure .
The pump also has a factory preset relief valve for
pump protection only . This setting should not be
tampered with .
B. Main Power On Lamp:
This lamp indicates that the main input supply volt
age is present .

D. Auto/Test Switch:
When toggled to the auto position the CC11 pump
and fan motors are energized when a 115 VAC signal
is received from the plasma process controller . The
plasma process controller should supply this signal
whenever input power is supplied to the plasma cut
ting power source .
When placed in the test position the CC11 pump and
fan motors are energized without receiving a signal
from the process controller .
