3.2.2.1

REMOTE WITH LOCAL (FRONT PANEL) LOCKOUT

To prevent unauthorized setting of the power supply to Local mode, a local lockout mode can be
enabled which prevents the power supply from being restored to local mode via the front panel.

With the power supply turned off, set the ANALOG I/O DIP switch, position 5 (see Table 2-2) to
ON. Now when the power supply is turned on the status display will read one of the following:

LOCK

- front panel controls locked, analog mode not enabled and no digital commands received.

aRwl

(analog Remote with local lockout) - front panel controls locked, analog mode enabled

dRwl

(digital Remote with local lockout) - front panel controls locked, analog mode disabled and

a digital command received.

Once the front panel is locked, it can only be unlocked by either of the following:

• turn the power supply off, set ANALOG I/O DIP switch position 5 to OFF, and then

power up again.

• send the following SCPI command via GPIB, RS 232 or LAN port:

SYST:KLOC OFF

NOTE: If the front panel is unlocked by SCPI command, the unit will be set to Remote

with Local Lockout when it is turned on again. Set ANALOG I/O DIP switch posi-
tion 5 to OFF to disable Remote with Local Lockout.

3.2.3

MENU STRUCTURE

Many KLP functions are accessed via the

FUNCTION

switch. This switch is disabled when the

unit is in setpoint mode (If the status display shows

SET

, tap either the

CURRENT

VOLTAGE

controls to take the unit out of setpoint mode (status display goes from

SET

to blank).

Pressing

FUNCTION

switch using a thin tool (e.g., a paper clip) accesses the menu and sub-

menu structure indicated on the four-character status display (see Figure 3-1). To scroll through
menu and submenu selections rotate either the

DC VOLTS

DC AMPERES

control. Tap the

DC OUTPUT

switch to select and proceed. Exit any submenu by tapping the

DC OUTPUT

switch when the status display shows

RTN

to return to the previous menu. To exit the Function

menu after all submenus have been exited, tap the

DC OUTPUT

switch when the status display

shows

EXIT

. Pressing the

FUNCTION

switch once within any menu or submenu will also exit

the Function menu.

3.2.4

VOLTAGE AND CURRENT CONTROL COARSE/FINE PREFERENCE

The

VOLTAGE

CURRENT

controls are shipped from the factory so that rotating either con-

trol produces a coarse adjustment; pressing the control in while rotating produces a fine adjust-
ment.
