3.2.6 Editing Channel Set Values
In the channel screen it is possible to edit set values of the selected channel. This is done by marking current or voltage
value by turning rotary encoder and applying this by pressing the rotary encoder button. An edit field beneath the shown
values will be displayed.
The edit value is shown with a digit hi-lighted by a cursor. A short press on the rotary encoder button and the cursor will
jump to the next lower digit. Turning the rotary encoder changes the selected value in the resolution of the digit.
Submit and apply of the edit value is done by pressing and holding the rotary encoder button for more than one second.
There are two modes of editing available: manual and auto-apply. In manual mode, the edited value is not accepted until
the user applied it with pressing and holding the rotary encoder button. In auto-apply mode the edit value is immediately
accepted as turning the rotary encoder.
3.3 Channel Switches and LE s
The front panel of the NHR device is equiped for each channel with a “On/Off” switch to turn the channel on and off, two
status LEDs (“OK” and “HV ON”) and two LEDs (“POS” and “NEG”) to indicate the selected polarity.
The green LED “OK” signals the general condition of the channel and the yellow LED “HV ON” signals measured output
voltage at the corresponding channel or is flashing shortly every time the user presses the corresponding “On/Off” switch.
Following behaviors are possible:
LED “OK” LED “HV ON” Meaning
not illuminated not illuminated An error event occurred, the channel cannot be switched on.
not illuminated illuminated An error occurred but there is still a measured voltage at the channel.
illuminated not illuminated The channel is switched off and can be turned on.

3.4 Remote Control
The NHR devices offer two remote control interfaces: USB and CAN.
With the USB connector, one NHR can be controlled with the iseg SCPI instruction set. Available control applications are
iseg Terminal and iseg SCPI Control. Please consider the NHR_SCPI_eng.pdf document for further details.
With the CAN interface connectors, up to 64 NHR/NHS devices can be controlled on one CAN line. Therefore every device
has to have a unique CAN Bus address, which can be configured in the Device Menu. Please consider
EDCP_MULTI_CHANNEL_CAN.pdf document for further details.
3.5 Polarity and Output-Mode selection
For all channels of NHR devices the polarity can be electronically switched. This can be done via the front panel
(M NU CHANN L S TUP CHANN L X POLARITY→ → → ) or via remote control.
Modules with Vnom=6kV (except option L) also provide switchable HV-output modes which allow to switch the nominal
values of a channel between 2kV/4mA, 4kV/ mA and 6kV/2mA. This can be done via the front panel (M NU CHANN L →
S TUP CHANN L X OUTPUT-MOD→ → ) or via remote control.
Switching the polarity or output mode is only allowed if the corresponding channel is switched off and discharged below
0.002*Vnom . The module blocks all switching attempts if these conditions are not satisfied.
CAUTION!
CAUTION!
The device is not designed to operate as a current sink.
Never apply external voltages of opposite polarity to the selected one or with values greater than the maximum
value of the selected output mode. This can damage the module.
3.6 Protection Features
3.6.1 Hardware Limit
The maximum output voltage for all channels (hardware voltage limit) is defined through the position of the
corresponding potentiometer Vmax . The maximum output current for all channels (hardware current limit) is defined
through the position of the corresponding potentiometer Imax . The greatest possible set value for voltage and current is
given by Vmax – 2% and Imax – 2%, respectively. The percental values always refer to the nominal values of the channel,
Vnom and Inom . E.g. for a 6kV/4mA module the reference values are 6kV and 4mA, independent of the selected output
mode.
The output voltage and current are limited to the specified value. If the maximum voltage or current of the selected
output mode (Vmode or Imode) is below this limit, this will further limit the output.
If a limit is reached or exceeded in any channel the corresponding green LED on the front panel turns off.
3.6.2 Safety Loop
A safety loop can be implemented via the safety loop socket (SL) on the front panel.
If the safety loop is active, then an output voltage in any channel is only present if the safety loop is closed and an
external current in a range of 5 to 20 mA of any polarity is driven through the loop. The loop connectors are potential free,
the internal voltage drop is approx. V.
If the safety loop is opened during the operation, the output voltages are shut off without ramp. Furthermore, the
corresponding bits in the „ModuleStatus“ and „ModuleEventStatus“ registers are set (see
EDCP_MULTI_CHANNEL_CAN.pdf). After closing the loop again, the „ModuleEventStatus“ register must be reset to turn the
channels on again.
NHR – NIM standard High Voltage Power Supply | Last changed on: 14.06.2017 | www iseg-hv com 14/19

By factory setup the safety loop is not active (the corresponding bits are always set). The loop can be activated by
removing the internal jumper. The jumper can be accessed via a ventilation slot on the bottom of the module (see
dimensional drawings for exact position).
3.6.3 Single channel Inhibit
INFORMATION
INFORMATION
INHIBIT is an external signal, that switches off the high voltage for the device or a specific channel
The Sub-D connector on the bottom of the front panel allows to install an Inhibit for each channel. The pin assignment is
as follows:
Channel 0- / GND 0 1 2 GND
SUB-D9 connector pin 1 2 4 5 6 7 8 9
Table 6: INHIBIT connector pinout
INHIBIT Option-ID: The INHIBIT pins are internally connected to the module GND via pull down resistors (approx. 10 kΩ).
This ensures that a disconnected cable always causes an interlock. HV generation according to the settings is only
possible if the corresponding INHIBIT pin is actively pulled to TTL High level.
INHIBIT Option-IU: The INHIBIT pins are internally connected to 5V via pull up resistors (approx. 10 kΩ). HV generation
according to the settings is possible with TTL High level or open INHIBIT pins. If the INHIBIT contact pin (n) is connected to
the module GND or a TTL-LOW potential for at least 100 milliseconds, an Inhibit signal is generated. The channel status bit
isExternalInhibit and the channel event status bit EExternalInhibit are set. One of the following reactions to this signal can
be programmed:
•No Action (default)
•Turn off the channel with ramp
•Shut down the channel without ramp
•Shut down all channels without ramp
These reactions can be programmed by the CAN interface, see chapter Delayed Trip in the
EDCP_MULTI_CHANNEL_CAN.pdf document for reference.
When the INHIBIT is no longer active (TTL-HIGH potential or not connected), the Inhibit flag must be reset before the
voltage can be switched on again (consider EDCP_MULTI_CHANNEL_CAN.pdf document).
3.7 Floating GN configuration
The NHR module is a module with Common Floating Ground (CFG). All HV-channels have a common return potential
(module GND), which is galvanically isolated from the crate GND. A protection circuit prevents differences between the
two GND potentials of more than 56V. The galvanic isolation can be removed by placing a jumper on a two-pin connector
located in a ventilation slot on the top of the module (see dimensional drawings for exact position).
The GND of the digital interfaces (USB and CAN) is isolated from both, the module GND and the crate GND.

3.8 The function " elayed Trip"
3.8.1 Operating principle
The function "Delayed Trip" provides a user-configurable, time-delayed response to an increased output current (Iout)
higher than the set current (Iset). The response to this kind of event can be, for example, to ramp down the channel with
the programmed ramp. A detailed description for the configuration can be found in the manual
CAN_EDCP_Programmers-Guide pdf
By a programmable timeout with one millisecond resolution, the trip can be delayed up to four seconds. During this time,
the output current is limited to the value of Iset (constant current mode).
The hardware regulation signals, constant voltage (CV) or constant current (CC), are sampled every millisecond by the
microprocessor. Once the constant current mode is active, the programmed timeout counter is decremented. If the HV
channel returns to constant voltage mode before timeout (i.e. Iout < Iset), the counter will be reset. So this process can be
restarted if the current rises again.
To guarantee a sufficient resolution for the current set values, a nominal current adequate to the application should be
selected. iseg offers HV modules with nominal currents reduced to 100 μA in all voltage classes. These are designated e.g.
for semiconductor detectors, which only require a few microampere operating current.
3.8.2 Modules with two current measurement ranges
High Precision NHR modules with two current ranges are a particular case. In these HV modules the high current output is
combined with a picoampere resolution in the low current measurement range. The range switching is done by the
microprocessor depending on Imeas :
High measuring range: Inom-low < Imeas < Inom
Low measuring range: 0 < Imeas < Inom-low
The typical value for Inom-low is 20 μA.
As long as a set current in the high measuring range is used, everything is working as described above. If a set current in
low measuring range is nomified, the current limitation is set to 120 % of the low measuring range.
Example: Inom-low = 20 μA current limitation is set to 24 µA if I→set = 10 µA
Now the channel operates in the low measuring range only. A software comparison of set current Iset and measured
current Imeas is performed in addition to the described hardware CC and CV signals sampling.
With this principle, two requirements are met:
•the output current will not exceed 24 µA even during fast changes and
•the delayed trip function is extended into the region of very small currents (picoampere) for these HV modules.
For the software comparison, a delay between 80 milliseconds and 1 second must be expected. This depends on the
modules ADC (Analog-to-digital-converter) configuration.
This time can be adjusted by changing the ADC sample rate to meet the requirements of the application. Higher ADC
sample rates lead to shorter delays but also reduce the resolution.
If the Delayed Trip function is activated the voltage ramp should be limited to 1 % of Vnom before. Higher values could
trigger a trip by internal charge balancing during a ramp, even though the output current does not exceed the set value
Iset. If the connected load contains capacities or if Iset is very small, it might be necessary to further reduce the ramp speed.
Alternatively, the Delayed Trip can be activated only after the completion of the ramp.
INFORMATION
INFORMATION
An activated KillEnable feature disables the Delayed Trip function.
NHR – NIM standard High Voltage Power Supply | Last changed on: 14.06.2017 | www iseg-hv com 16/19

An active Kill nable function disables the Delayed Trip function. If Kill nable is active and a trip occurs, the channel is shut down
without ramp at the fastest hardware response time (smaller than 1 ms). However, the actual discharge time strongly depends on
the connected load.
