ENTER. The stored settings for voltage, current, overvoltage protection and overcurrent protec-
tion replace the current values, and the unit returns to command entry status.

ENABLING REMOTE ANALOG CONTROL

The power supply may be controlled by external analog voltages (see PAR. 3.5), but the feature
must be enabled first. With the power supply in command entry status , press MENU key until
LCD reads Extern. Ref On or Extern. Ref Off and the bottom line reads 0=Off,
1=On

. Enter 1 (enable) or 0 (disable), then press ENTER to enable or disable the feature. Refer

to PAR. 3.5 for using this feature.

LOCAL MODE PROGRAMMING OF THE POWER SUPPLY.

Local mode programming offers the user 40 memory locations that can be used to program the
power supply. Each location defines values for output voltage, output current, overcurrent pro-
tection, overvoltage protection, time duration (between 0.1 and 2.5 seconds) for the pro-
grammed settings, and the address of the next memory location in the program.

NOTE: When programming sequential voltage levels, it is important to set the Overvoltage to

accommodate the highest voltage of the sequence. Otherwise, when going from higher
to lower voltage levels, the overvoltage protection will trip and shut down the unit.

CREATING OR MODIFYING A PROGRAM (PROGRAM EDIT MODE)

Creating a program and modifying an existing program are identical except that a program mod-
ification requires only selected parameters to be changed rather than all new parameter values.
With the power supply in command entry status , press EDIT PROG key. The top line indicates
the STARTaddr. nn, where nn is one of 40 memory location. To select a different address,
enter new value and press ENTER.

The top line of the LCD indicates the active memory location, e.g. ViewVAL Mem <n> where n
is the memory location previously chosen. The bottom line of the LCD indicates the parameter
on the left (Iset, Vset, OVset, OCset, TIMEval, NEXT STEP), the parameter’s value on the
right, and data entry status in the middle. To modify time values see PAR.3.4.15.1.1.

Press ENTER to accept displayed value, or enter new value and press ENTER to accept new
setting (the LCD displays the next parameter). Press CLEAR to exit Program Edit mode without
changing value. Use

or

key to scroll forward (or backward) to view next (or previous)

parameter or memory location. For a program to run once, then stop, see PAR. 3.4.15.6; to
cycle a program continuously, see 3.4.15.4. After all program values have been set, press
CLEAR or ENTER to exit Program Edit mode. Setting up a program can be made easier by
copying the Memory Location Worksheet (Table 3-3) and filling in the values before program-
ming the power supply.

3.4.15.1.1 MODIFYING PROGRAMMED TIME INTERVAL

The TIME key offers a quick and easy way to change the time for any memory location. With the
power supply in command entry status , press TIME key. The LCD displays TIMEval

nn

where nn is the time value set for the selected location. Press ENTER to accept displayed
value, or enter new value (between 0.01 and 300 seconds) and press ENTER to accept new
value or press CLEAR to exit without changing value. The unit returns to command entry status

. Refer to PAR. 3.4.15.1.2 if accuracy of time values is important.
