PS 5000 A Series
1.9.4 The control panel (HMI)
The HMI ( H uman M achine I nterface) consists of a display, two rotary knobs with button function and five pushbuttons.
1.9.4.1 Display
The blue, illuminated LCD display is divided into a three rows:
Actual values U / I,
Errors / alarms,
Regulation mode
Set values U / I / P,
Values OVP, OCP, OPP,
Fine adjustment mode
Status, Recall feature
•
Actual values area (upper row)
In normal operation the DC output values (actual values, large numbers, 7-segment) of voltage and current are
displayed with four digits each. The display format of values is according to what’s listed in 1.9.4.3. Below the actual
values, it shows the actual regulation mode (CC, CV, CP) as long as the DC output is switched on.
• Set values area (middle row)
The set values of voltage and current are displayed here, which are adjustable with the left hand and right hand
rotary knobs below the display, when operating the device manually. While doing so, the adjustment mode can be
switched between fine and coarse by pushing any of the rotary knobs.
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.
