The device incorporates an interlock circuit through which the supply voltage of the high voltage
sources is switched. It is a closed circuit with three switching points (break contacts). Its source
voltage is 24 V (carried out via +24V Ilck), quiescent current is 10mA. The switching points are:
1. Connector X4 Power / Interlock:
with terminals +24V Ilck and Interlock, the device can be looped into an interlock circuit
(potential-free break contact); these terminals must be connected together in order to allow
the high voltage sources in the device to be switched on;
2. Connector X1:
with IL_IN (X1.3) and IL_R (X1.16) the device can be looped into an interlock circuit (potential-
free break contact); if these pins are not used, they can be bridged using the DIP switch in the
device;
3. Lever key HV on / HV off on the front panel.
Only if all three contacts are closed, the supply voltage of the high voltage sources will be switched
on. The device will then still be in the Interlock shutdown state. The high voltage generation is not
functionally activated till the Interlock shutdown state is finished by Shutdown Reset.
The HV on display indicates that the supply voltage of the high voltage sources is switched on.
The device must be disconnected from its power supply before carrying out any works on the test
set-up or before touching the output terminals.
