The high voltage is turned on/off with the analogue interface control signals “ON” and/or “INHIBIT”.
3.1.1 Set values
A voltage of 0 – 5 V
, applied to pin 8 (reference potential pin 1) of the signal connector "AIO", controls the output voltage of
0 - V
nom
. Pin 4 controls the output current from 0 - I
nom
in the same way.
3.1.2 Monitor voltages
Monitor voltages (0 - 5 V) proportional to the output voltage and output current are available at Pin 7 and Pin 2 of the connector
“AIO”, respectively (reference potential Pin 1).
3.1.3 INHIBIT
By applying a low level signal at pin 3 of the connector “AIO“, the high voltage generation will be shut off immediately and will be
blocked. High voltage generation is activated with a high level signal or open contact at pin 3 of the connector “AIO“.
3.1.4 ON
If high voltage generation is enabled (INHIBIT) and after a falling edge at pin 5 of signal connector "AIO" (reference potential pin 1)
the output voltage increases to the set value (VSET_V at pin 8 of connector "AIO") or until the set value of the output current is
reached (VSET_I at pin 4 of connector "AIO").
By applying a high level signal at Pin 5 of the connector “AIO“, the high voltage ramps down with the specified voltage ramp
speed.
3.1.5 ARC (only with option ARC)
If an ARC is detected (see 2.3 ARC Management ) the level at pin 6 of signal connector "AIO" (reference potential pin 1) is low for
approx. 1 ms.
