6.1 The display
Figure 4 depicts an overview of the dot matrix display and the
control panel. During normal operation, the display areas show
the actual values of voltage (left side) and current (right side)
and device status (middle). In preset mode, the left display area
shows the set values of voltage (Preset Voltage), of the overvolt-
age protection threshold (Preset OVP) or the undervoltage limit
(Preset UVL). The right display area shows the set values of
current (Preset Current) or power (Preset Power, only models
from 1 kW). In the device setup the display is used to show
adjustable parameters and settings.
The status area in the middle can show following status:
CV
- Constant voltage regulation (only when output is „on“)
OT
- Overtemperature error
OVP
- Overvoltage error
CC
- Constant current regulation (only when output is „on“)
CP
- Constant power regulation (only when output is „on“)
Fine
- Fine adjustment for both rotary knobs active
PF
- Power fail (input voltage failure, from firmware 6)
Legend:
(1) - Left display area: Actual voltage or set value U, UVL, OVP
(2) - Status area: status display like CC, CV etc.
(3) - Right display area: Actual current or set value I, P
(4) - Control buttons: Setting the device condition etc.
(5) - Rotary knob right: Set value adjustment of I and P, as well
as settings in the device setup
(6) - Preset buttons: Switching to set value display
(7) - Rotary knob left: Set value adjustment of U, UVL, OVP, as
well as parameters in the device setup

6.2 Pushbuttons on the control panel
6.2.1 Pushbutton Preset Voltage
During normal operation, this button is used to switch the display
from actual to preset value of the output voltage (i.e. preset
mode). The left display area will then show like this:
In preset mode, the left rotary knob (
Voltage / UVL / OVP
) is
used to adjust the voltage set value the same way as during
normal operation. The adjusted value is instantly transferred
to the output.
Note
The set value adjustment can be limited by the undervoltage
threshold UVL. Also see 6.2.2.
A second push leaves the preset mode instantly or it will end
automatically, if no preset button is pushed or any set value is
altered within 5 seconds.
During remote control by analogue or digital interface, the
preset mode can be used to check the voltage set value that
is given from remote.
The button might be locked by the condition
LOCK.
In memory selection mode the button is also used to switch to
the voltage set value of the selected memory set, but in this
mode the set value is not transferred to the output. The left
display area will then show like this:
