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 .
