About the power supply
The currently active control mode is displayed to the right of
the related actual values. For instance, the abbreviation „CV“ is
displayed next to the actual value of voltage, because it means
that „Constant voltage“ mode is active. The output values are
limited by the active control mode:
- limited by the voltage set value
(= Constant Voltage)
- limited by the power set values
(= Constant Power)
- limited by the set value of current
(= Constant Current)
- limited by the set value for internal resistance
(optional at U/I/R mode), indicated next to the
actual voltage
(= Constant Resistance)
Additionally to the state of the output an alarm, a warning or a
signal can be displayed:
Alarm
Example:
= Overtemperature
Warnings
Example:
= Overvoltage
Signals
Example:
= Overcurrent
The location from where the unit is currently controlled is dis-
played below the output state. This location is absolute, which
means that you cannot control the unit from elsewhere without
changing the location.
local
Control only possible at the unit
remote
Remote control via communication interfaces
(IF-C1, IF-R1, IF-U1 etc.)
extern
Remote control via built-in or optional, analog
interface
6.4 Switching the unit on
The unit is switched on with the mains switch. After it has been
switched on, the displays shows the device type and, if pro-
grammed, a user text.
The user text can be entered via one of the digital interface
cards using an included LabView VI. This text is intended to
identify a single unit in an complex environment of multiple units.
After the internal system has been verified and has booted, the
last state of the power supply (set values, alarm management
etc.) is restored. The return state of the output after a mains
loss (power fail error) or after the unit was switched on can be
set in the
Profile
menu.
6.5 Switching the power output on
By pressing the
button the power supply output is
switched on, as long as it is not overridden by the input pin
„REM-SB“ (13) of the built-in analog interface or optional analog
interface card IF-A1, because the pin has higher priority. If so
and when trying to switch the output on by the button, the dis-
play will indicate the status text „
auto ON
“, noticing the user
that the output will switch on as soon as the override from the
pin is removed.
Note
In
local
state (see section 6.9), the pin REM-SB of the analog
interface (internal or external) is inoperative.
The display should then show the output condition with „
ON
“.
The
button switches the power supply output off. This
state is displayed with
OFF
.
6.6 Adjusting set values
Note
Set values can be adjusted in coarse or fine steps (see table
below for step widths). Switching from coarse to fine or vice
versa is done with the two rotary knobs next to the display.
These also have a pushbutton feature. The last selected
mode, coarse or fine, is not saved when the device is switched
off. After powering the device, coarse mode is active by default
with firmware C3.13 or higher, else fine mode is default.
As long as
extern
or
remote
is not displayed, the set
values for voltage, current or power can be set manually.
The way of set value submission is selected in the device setup
at
Accept set value.
The setup is accessed with button
->
Profile
->
General settings
->
Control panel
.
See
„7.4. Configuring the control panel“
Direct setting of the set values
Using the rotary knobs directly sets the set values.
The left rotary knob adjusts the voltage. The set value of the
voltage is displayed inverted while it is selected and adjusted.
The right rotary knob either sets the set value for the current, for
the power or internal resistance (optional, unlockable, with U/I/R
mode chosen). The selected set value is displayed inverted.
With the
SELECT
keys
the set value for the power, with
the set value for the internal resistance or with
the set value for the current is selected.
The maximum adjustable power can also be limited.
