Operation Manual
OUTPUT Section
This section is used to open and close the output relay. Output terminals are
available in the universal AC connector located in the OUTPUT section, as well
as on the rear panel of the CW unit.
Output ON Lamp. When lit, this lamp indicates that the CW output relay has
been set to the on position, and power is on the output terminals.
Output OFF/RESET Button. This switch allows you to energize or de-
energize the output terminals of the power supply. If the unit is operating in the
fault mode, and if the fault condition has cleared, then cycling this switch will
restore normal operation.
3.2 Front Panel Overview
After performing the power-up operations, the CW reads storage location 0 for the
voltage range and the five program values. The CW enters into left and right measure
modes. The VOLTS LED on the left, and the AMPS LED on the right will be illuminated
and the measured volts and measured amps will be displayed.
Specify which measurement to display in the VOLTAGE/POWER section of the front
panel by pressing the left MEASURE button until the VOLTS, WATTS, VA, PF, or OVP
appears on the left display. The relevant LED will be illuminated.
Press the right MEASURE button to specify which parameter, AMPS, Hz, Pk AMPS,
CF, or I LIMIT, is displayed in the CURRENT/FREQUENCY section of the front panel.
The relevant LED will be illuminated.
Press the left PROGRAM button to program the left side Voltage or OVP setpoints.
Once in Program mode, the last program operation is automatically re-entered, the
relevant LED is lit, and the display changes to indicate the program value that is
selected to change. If the PROGRAM button is pressed again, the next programmable
setpoint parameter is displayed and the relevant LED is lit to annunciate the new
selection. While the PROGRAM LED is illuminated, turn the rotary knob to change the
displayed parameter. As the knob is rotated, the parameter is increased or decreased
in value. The change made to the programmable parameter overrides the original
value.
The CW output is opened and closed by pressing the OFF/RESET button in the
OUTPUT section of the front panel. The ON LED is illuminated when the output is
closed.
The voltage range is changed from High to Low or vice-versa by pressing the V RANGE
button when the left Program Volts mode is selected. When the range is changed, the
voltage is programmed to 0, the output relay will open if it is closed, and the left section
will remain in voltage program mode. The HIGH or LOW LED is illuminated to indicate
the presently selected range.
