AMETEK CTS
11.3.
Front view NSG 3150
Reference ground connector
The earth connection between the CDN and the generator is realized via the shield of the HV connectors. There is no need to
connect the ground connector from the generator itself.
Without using a Teseq CDN, the NSG 3150 can be efficiently connected to the ground reference plane using a ground strap
connected to the reference ground connector point.
Surge output
These output (high, low) connects the surge output impulse to a 1-phase or 3-phase coupling unit or to another external coupling
unit.
These coaxial high voltage output are protected by a plexiglas window. The surge output is potential free (floating). The inner
conductor of each connector is the surge high and surge low connection respectively, while the outer conductor (shielded) is
connected to the NSG 3150's ground point.
Cable insulation for EUT surge output must be rated for 20 kV
Indicator LEDs
The five indicator LEDs serve to show the most important test system conditions:
LED indicator function
Power on
Pulse
Pulse blinking
High voltage active
EUT-Power on
Error
The LEDs switch on and off during the boot period and when errors occur.
Touch screen and user interface
The color 7" touch screen display controls include a wheel and 3 sensitivity keys used to 1, 10 or 100 steps per wheel click. The
Start, Stop, and Pause keys are used to control the procedure.
All user interface function menus and sub-menus are described in chapter 7, standard user interface.
Description
Instrument/system in operation
Shows the occurrence of a pulses or a test event
The generator is set to a safe position and need some seconds to move the switch
into the final position.
Shows that high voltage is present in the instrument (in line with "Pulse" LED)
Indicates when the power supply to the EUT is present at the EUT connector on the
front panel
Indicates that a system error has occurred
