Display Description
Locked The HMI is locked
Remote The device is under remote control from...
Analog ...the built-in analog interface
USB ...the built-in USB port or a plug in interface module
Ethernet ...the built-in Ethernet/LAN port
Local The device has been locked by the user explicitly against remote control
1.9.4.2 Rotary knobs
As long as the device is in manual operation, the two rotary knobs are used to adjust set values, as well
as setting the parameters in the settings menu. For a detailed description of the individual functions see
section „3.4 Manual operation“ on page 31.
1.9.4.3 Pushbutton function of the rotary knobs
The rotary knobs also have a pushbutton function which is used in all menu options for value adjustment to move
the cursor by rotation as shown:
1.9.4.4 Resolution of the displayed values
In the display, set values can be adjusted in xed increments. The number of decimal places depends on the
device model. The values have 4 or 5 digits, while actual and set values related to the same physical unit always
have the same number of digits.
Adjustment resolution and number of digits of set values in the display:

OVP, U-min, U-max

30 A / 50 A 4 0.01 A

In manual operation every set value can be set in the increments given above. In this case
the actual output values set by the device will lie within percentage tolerances as shown in the
technical data sheets. These will inuence the actual values.
1.9.5 Sense connector (remote sensing)
During constant voltage operation (CV) and in case the adjusted output voltage has
to be held constant on the load and not on the power supply’s DC output, remote
sensing can be used in order to compensate for the voltage drop on cables up to
a certain limit. The maximum possible compensation is given in the technical data.
