Operating the device
Pushbutton Memory Select M1-M5
This button cycles through the 5 memory sets, each with set
values for U, I and P, as well as UVL and OVP. From here, the
selected memory set can be edited, stored or submitted. The
button only works if the output is off. The memory mode and
the selected memory set number are displayed like this:
By using the button the user can:
a) Adjust values
Output off, short push of the button, the display changes to the
first memory set as displayed above.
Now the set values of U (left) and I (right) of the selected me-
mory set can be adjusted. The other adjustable values can be
accessed by pushing the corresponding preset buttons.
Further pushes will cycle through the memory sets up to number
5 and then exit memory mode.
The adjusted values remain as long the device is powered,
but are not submitted to the output set values and are not
saved yet!
Pushbutton Memory Start / Memory Save >3s
This pushbutton is either used to submit the values of the
memory set that has been selected before by button Memory
Select M1-M5 to the output or to save the memory to internal
flash. The button only works if the output is off.
By using the button the user can:
b) Submit only
Output off, memory set is selected (1-5), button is pushed
shortly --> the values of the memory set are submitted to the
set values of the output and the memory mode exits. In order
to use the new set values, the output is switched on as usual
by button Output On or by remote control.
Attention! Submitting the values does not save them!
c) Save only
Output off, select memory set(s), adjust the values as desired,
the push the button >3s --> all memory sets are saved to internal
flash, but none is submitted to the output. The output remains
off, the memory mode exits after saving.
The memory sets can also be defined by remote control and
corresponding commands using a digital interface (except
GPIB). They're stored immediately.
The button may be locked by the condition LOCK. See below.

Pushbutton Local
This pushbutton activates or deactivate the LOCAL mode. In
LOCAL mode not remote control of the device is possible.
Attention! Activation of LOCAL mode results in immediate return
from remote control (analogue or digital) and locks the device
against further attempts to control it remotely, until LOCAL is
cleared again.
LOCAL mode is indicated by LED „Local". As long as LOCAL is
not active, the LED „Remote" indicates an active remote control
by analogue or digital interface.
The button may be locked by the condition LOCK. See below.
Pushbutton Lock / Unlock
This pushbutton activates or deactivates the control panel lock.
The LOCK mode locks all buttons, except the LOCK button itself,
and the rotary knobs against unintended operation.
Attention! Activation of the LOCK mode instantly exits any
preset or memory mode, if currently active. The display will
return to normal display of actual values.
Pushbutton Output On / Output Off
This pushbutton is used to manually switch the power output
on or off, as long as the device is not in remote control mode.
The output condition is always indicated by the LEDs „Output
On" or „Output Off". If the output is switched on, the device
indicates the currently active regulation mode (CC, CV or CP)
in the status area in the middle of the display.
The button may be locked by the condition LOCK. See above.
The button also acknowledges the errors. See sections 7.4 and
7.5 fore more information.
If an overtemperature error occurs, the LED „Output on" will
flash to indicate that the device output will automatically switch
on, once the OT condition is gone. This can be interrrupted by
manually switching the output off with the pushbutton. The LED
will stop flashing and LED „Output off" will be lit.
