KEPCO MBT Series - Manual (Page 115)

MBTSVC111609
4-9
A total of 99 steps are available, and since each program uses at least one step, this leaves 89
steps which can be split, as desired, among a maximum of ten programs; a single program may
contain a maximum of 90 steps. Programs can be entered or modified from the keypad without
changing the current status of the power supply; status will only change when the program is
executed.The MBT Power Supply can execute one program at a time; programs can be set up
either cycle indefinitely or stop after one complete execution cycle. (Refer to PAR. 3.2.2.9.)
4.1.13.6 STATUS In addition to the five LEDs (see PAR. 4.1.13), the keypad allows on-line observation
of actual output voltage and current, as well as programmed overcurrent and overvoltage val-
ues. Pressing the SHIFT and “.” (decimal point) keys causes these parameters to be displayed
on the LCD display.
4.1.13.7 MENU-SELECTABLE PARAMETERS The keypad also allows selection of additional miscella-
neous features through a menu selection. Menu selections allow the operator to:
• Enable/disable the MBT speaker which provides audible beeps for each keypad entry.
• Enable/disable the VOLTAGE and CURRENT controls and slew keys, requiring the
exact output value to be entered on the numeric keypad.
• Use the front panel to control the operating parameters of another Kepco Power Supply
connected to the IEEE 1118 bus by entering the node address of the power supply to be
controlled at the keypad. (One of the Power Supplies connected to the bus must be an
MBT "G" option unit.)
• Calibrate the MBT Power Supply. Step-by-step instructions for calibrating the unit are
displayed on the LCD display.
• Establish values for overvoltage and overcurrent protection.
• Establish the increment value for operation of the Slew keys.
4.1.14 REMOTE CONTROL
Remote control of the MBT power supply is accomplished using either SCPI or CIIL program-
ming languages (see PAR.s 3.3.5 or 3.3.6, respectively). The following functions can be per-
formed via remote control of the MBT Power Supply:
• Set values for output voltage and current limit (Voltage Mode).
• Set values for output current and voltage limit (Current Mode).
• Reset output to zero.
• Set Mode (Voltage or Current).
• Enable or disable the output.
• Measure actual values of output voltage and current.
• Read error messages.
