PSI 5000 A Series
The left hand rotary knob is assigned either to the output voltage and related parameter OVP or the power and the
related parameter OPP, whereas the right hand rotary knobs is always assigned to the output current and related
parameter OCP. In remote control condition, the set values given from remote are displayed here.
This row furthermore indicates alarm conditions. See „3.6. Alarms and supervision“ for details.

This row indicates various statuses:
Display Description
Recall 1-9 Number of the currently selected preset in recall mode (see 3.4.6)
Remote The device is under remote control via USB interface

Lock The control panel (HMI) is locked (see 3.4.7)
Local The device has been locked by the user explicitly against remote control
On / Off Indicates the state of the DC output
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. For a detailed
description of the individual functions see section „3.4. Manual operation“. Both rotary knobs have an additional
pushbuttonfunctiontoswitchtheadjustmentmodebetweenne(displayshowFine) and coarse adjustment. Both
knobs can switch both modes. See 3.4.3 for details.

decimal place (see table in 1.9.4.3).
1.9.4.3 Resolution of the displayed values
All adjustable values have 4 digits. The number of decimal places depends on the device model. Actual and set
values related to the same physical unit always have the same number of digits.

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.
