Using the power supply
7.8 Unlocking the U/I/R operation mode
Enable R mode +
 R mode available:
YES The U/I/R operation mode is unlocked and can be
used
NO U/I/R mode not enabled yet
The U/I/R operation mode can only be used after it was unlocked
withaPINcode.Thismodealsohastobeconguredintheprole
(seealso„7.1Deningoperationparameters“).
The PIN code to unlock the U/I/R mode costs. In case you intend
to use this mode, you can add this to your order or purchase it
later.
Activate R mode via pin code:
Use the pincode you received from your dealer here.
7.9 Lockingthedeviceconguration
Setup lock +
Itcanbenecessary,forsecurityreasons,tolockthedevicecon-
guration from access. You can enter a PIN code here, consisting
of 4 numbers, each from 0 to 15.
Lock setup via Enter the PIN code
pin code: {0..15} {0..15} {0..15} {0..15}
The lock can only be disabled with the same PIN code or by
resetting the conguration with
Reset conguration. The
latter one deletes the custom setup and should only be used is
case the PIN code has been forgotten.
If you activate the lock with the PIN code you can only change
thecongurationagainafterthePINcodewasenteredagainand
the setup is unlocked.
8. Digital interfaces
8.1 General
The power supply supports various interface cards for communi-
cation (or analogue control, with IF-A1). All cards are galvanically
isolated up to 2000V.
The digital interface cards IF-R1 (RS232), IF-C1(CAN) and IF-
U1(USB) use a uniform communication protocol. Up to 30 units
can be controlled from a PC at once with these cards.
The GPIB interface IF-G1 (IEEE 488) offers a SCPI command
structure for up to 15 units per bus. The analogue card IF-A1
isagalvanicallyisolated,analogueinterfacewithcongurable
in- and outputs.
8.2 Conguringtheinterfacecards
Theinterfacecardshavetobeconguredonceandeachtime
they’re replaced. This is done using the menu Communi-
cation.

Device node Default: 1
= {1..30}
Up to 30 device nodes (addresses) can be as-
signed to device, one per unit. A device node
must only be assigned once if multiple units are
controlled. When using the GPIB card IF-G1
do not set adress >15, even if possible. GPIB
only supports 15 client devices.
Except for the analogue interface it is absolutely necessary to set
the unit’s address (Device node) when using interface cards.
Onlythentheunitcanbeidentiedcorrectly.
Slot A: { IF-… } depends on what is equipped
An equipped interface card is automatically recognized by the
unit. The menu selection displays the equipped card with its
product code.

9. Internal analogue interface
9.1 General
The internal 15 pole analogue interface is located on the front
and offers, amongst others, following possibilities:
• Remote control of current and voltage
• Remote control of power 0...100% (models from 1kW)
• Remote control of voltage, while current = 100%
• Remote control of current, while voltage = 100%
• Remote monitoring of status (OT, OVP, CC, CV)
• Remote monitoring of actual values
• Remotely switching the output on/off
Useful hints:
• Controlling the device with analogue voltages requires to switch
it to remote control with pin „REMOTE“ (5).
• Before connecting the application that is used to control the
power supply, make sure to wire all leads correctly and check if
theapplicationisunabletoinputvoltageshigherthanspecied
(max. 12V).
• The input REM-SB (remote standby, pin 13) overrides the
pushbutton ON. It means, the output can not be switched on
bythebuttonifthepindenestheoutputstateas„off“.
