Handling the device
Digital inputs
(Default: LOW )
The digital inputs can be selected to be low-active or
high-active.
If set to
LOW the input will execute its defined function
at low input level. See the technical specs table of the
analogue interface for details.
If set to
HIGH , the input will react to input level high.
Digital outputs (Default: LOW )
The digital outputs can be selected to be low-active
or high-active.
The outputs will signalise their defined function with
the selected output level, i.e. by switching to GND at
LOW or to high potential at HIGH . See the technical
specs table of the analogue interface for details.
4.5.3 Menu item „Communication“
If the device is equipped with a digital interface card,
this menu entry is used to configure communication
settings. A detailed description of those settings can
be found in the external user guide of the interface
card.
4.5.4 Menu item „Options“
This menu page provides a possibility to reset the
device to default settings and to lock the control panel
with a pin code.
Reset configuration
If YES is selected at the confirmation prompt „ Are
you sure? “, all editable parameters are reset to their
default values. With NO , all settings remain unaltered.
After a configuration reset, the value „ U output “ of
the selected voltage profiles has to be submitted
once again.
Lock setup
After entering a 4 digit PIN code with the arrow but-
tons, the control panel is locked, except the unlock
button. The four numbers can be 0 - 15, which results
in 65536 combinations. Unlocking is done the same
way, by entering the PIN code again. If the PIN code
is lost, the lock can only be removed by doing a „ Reset
configuration “. See above.
4.6 Alarms
The device will indicate different alarms in the display
using the symbol and an abbreviation, as well as
the output pin ERROR on the analogue interface.
Those alarms have to be acknowledged by the user
with button . Some alarms ( OT , OVP ) will switch
off the output, which can be switched on again after
acknowledgement.
The only exception is the OT alarm, where the output
can automatically switch on again after the device has
cooled down, if in menu „ General settings “ the option
„ OT disappear “ was set to „ auto ON “.
4.6.1 Alarm types
OT - Overtemperature shutdown due to overheating
OVP - Overvoltage shutdown due to internal or ex-
ternal cause
EXT - Remote control error
Notes:
•
If OT or OVP occurs, the output is switched off, no
matter if manual or remote control was active
•
The alarm EXT shows that an attempt was made
to switch to remote control by analogue interface
while one of the voltage profiles 2-5 resp. 2-6 was
selected. In order to switch to analogue remote
control, first select voltage profile 1 via button.
Also see section 4.2.
5. Remote control
5.1 By digital interface
With the optionally available, digital interface cards
(USB, RS232, Ethernet or CAN) the device can be
completely remotely controlled and monitored. For
details of features and technical specs see the user
manual of the interface cards. With CAN, multiple
power supplies can be networked.
5.2 By analogue interface
Set values that control output voltage and current
can be given to set value inputs VSEL and CSEL with
control voltages of 0...10V or 0...5V, depending on
the selected control voltage range (see section „4.5
The setup menu“).
The actual output values of voltage and current are
put out as monitoring voltages to outputs VMON
and CMON with 0...10V or 0....5V, depending on the
selected control voltage range (see section „4.5 The
setup menu“).
Before controlling the device remotely is has to be
switched to remote control with pin 7 „Remote“ pulled
to GND. Both set values have to be given. If only one
of both is going to be adjusted, the other one can be
tied to VREF in order to be 100%.
Note: the digital inputs are not CMOS compatible.
In order to pull those down to GND, a low-resistive
contact or switch like from a relay or transistor etc. is
required. Digital outputs of a PLC or similar may not
suffice here. Consult the technical documentation of
your controlling hardware.
