3.2.13 RECALLING STORED OUTPUT SETTINGS
With the power supply in command entry status
(:_:_:)
, press RECALL . The LCD reads
RECALL mem (=_=_=) nn
where nn is the memory location holding the settings to be
retrieved. Press CLEAR to exit without changing setting. Press ENTER to validate existing loca-
tion, or enter memory location (from 1 to 40) and press ENTER . The stored settings for voltage,
current, overvoltage protection and overcurrent protection replace the current values, and the
unit returns to
(:_:_:)
command entry status. The default value at power-up for the Recall
command is 01. During normal operation, the location last used is displayed.
3.2.14 FIRMWARE VERSION
To display the firmware version of the power supply, the power supply must be in command
entry status
(:_:_:)
. Press the MENU key until the LCD displays
BHK XXXX,SSSSSS mm-
dd-yyyy,V.zz
where XXXX indicates the power supply model (e.g. XXXX = 1000 for BHK
1000-40MG), SSSSSS indicates the serial number, mm-dd-yyyy indicates the factory calibration
date and V.zz indicates the firmware version. Press
ENTER or CLEAR to exit menu and return
to command entry status.
3.2.15 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 0.01 and 655.35 seconds) for the pro-
grammed settings, and the address of the next memory location in the program.
3.2.15.1 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 dif-
ferent address, enter new value and press ENTER .
The factory default values for all memory locations is: 0 Volts, 0 Amperes, Overvoltage set to 1.1
x E
O
max, Overcurrent set to 1.1 x I
O
max, time duration set to 0.01 Sec and Next Step is set to
0.
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.3.2.15.1.1.
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 param-
eter or memory location. For a program to run once, then stop, see PAR. 3.2.15.5; to cycle a
program continuously, see 3.2.15.4. 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 3-4) and filling in the values before programming the power
supply.
