K1 signalling socket pin assignment
A External pulse
B External reset
Pin 1
Not assigned
Pin 2 Pulse input:
For external pulsing,
connect a potential-
free normally open
contact to Pin 2 and 5.
An internal resistor of 5 kOhm to 12 V
DC
is built in.
Pin 3 Monitor voltage 0 – 10 V
DC
:
Connect monitoring of high voltage to Pin 3 and 5. Internal
resistance 5 kOhm.
Pin 4 Signal output thermal protection (open collector output):
Connect monitoring of thermal protection cut-off to Pin 4
and 5. Internal resistance 500 Ohm.
Pin 5 Ground (GND)
Pin 6 Reset signal input:
For external resetting, connect a potential-free normally
open contact to Pin 5 and 6. Internally a resistor of 5 kOhm
and a diode to 12 V
DC
are built in.
Pin PE Ground
5.2.1 Pulsing high voltage
Precondition:
Connection of a potential-free normally open contact via signalling
line K1 UL to Pin 2 and 5 of signalling socket K1.
During pulsing, the HV is switched off by closing the potential-free
normally open contact, and switched on by opening it. The
maximum pulse frequency for the HV is 2 Hz.
NOTE:
The external normally open contact must be a potential-free normally
open contact.
The reset button will flash when the HV is switched off.
