The safety circuit locks the system and enables the
generation of the high voltage impulses in the
generators.
Design
Each device that has internal relevant high voltage
unit, includes a safety circuit. The safety circuit works
like an “open collector circuit”, where the external
safety loop must be closed for switch on the high
voltage.
Safety circuit closed
The device will generate high voltage pulses after start
Safety circuit open
The device will switch off the high voltage and
discharges the high voltage circuit
The warning lamp offers a voltage free contact that
indicates the status of the generator system.
Design
Each device with warning lamp function can short
thewarning lamp contact. An external powered relays
max. 60 V / 2 A controls the lamp. The user is
responsible for the warning lamp power supply
Warning Lamp switch closed (red):
- Safety circuit is closed and
- TEST ON is on
Status: RED Lamp, Power on EUT output,
High voltage can be “ switched ON”
Warning Lamp switch opened (green):
- Safety circuit is open and / or
- TEST ON is off
- Generator is switched off
Status: GREEN Lamp, no danger, High voltage is off
