MCM 30 Electrostatic Charging Generator
5. OPERATION
ON / OFF SWITCH -
Switch turns the MCM 30 charging generator on or off. Note that
position #8 on the Interface Terminal Block must be grounded (i.e. connected to position
#11) to energize the unit using the on/off switch on the face of the unit.
SETTINGS KNOB -
Knob controls the output of the High Voltage supply. In the Voltage
Mode it provides for output adjustment between 3 and 30 kVDC. In the Current Mode it
provides for output adjustment between 0.1 and 1 mA. The Settings knob is also used in
conjunction to the MODE/SETUP switch to select voltage or current mode of operation
along with the unit address function.
MODE / SETUP
– Is a push button tactile switch located on the front panel which toggles
the Mode of operation when pressed or is used to enter the Setup sub menus. Pressing this
button causes the Status LED to light.
Voltage Mode Function - In Voltage Mode operation, (the Voltage Mode LED will be
lit), the MCM30 will display the output voltage on the “bar graph”. Pressing the Mode /
Setup button will cause the Current Mode LED to light and the output LED “bar graph”
will display the output current. After approximately five (5), the unit will revert to
displaying the output voltage.
Current Mode Function - In Current Mode operation, (the Current Mode LED will be
lit), the MCM30 will display the output current on the “bar graph”. Pressing the Mode /
Setup button will cause the Voltage Mode LED to light and the output LED “bar graph”
will display the output voltage. After approximately five (5), the unit will revert to
displaying the output current.
Setup Function – To enter the Setup function the MCM 30 needs to be de-energized
(Green Power LED is OFF). Then energize the MCM 30, (Green Power LED is lit) and
within five (5) seconds press the MODE / SETUP button twice (2) the Status LED will
flash each tome the button id pressed. Once the MCM 30 is in setup mode either the
Voltage or Current LED will be flashing. The Settings knob will be used to select between
Voltage or Current Mode control.
NOTE -
The MCM 30 will operate in voltage control mode OR current control
mode (not both at the same time). In voltage control mode, the unit will adjust
output current as needed to maintain the output voltage set-point. In current
control mode, the unit will adjust output voltage as needed to maintain the output
current set point. If the unit is unable to meet the desired set-point, it will trigger
an overload light.
