Logic outputs

The device contains two potential-free outputs K1 (clamps 24, 21, 22) and K2 (clamps 14, 11, 12) which are used to report the system state. The standard device uses two relays to communicate with a SPC or an indicator. A buzzer may also be connected to this outputs.
The relay outputs are change-over contacts for an AC voltage up to 230V and a current up to 5A.

The outputs of the standard device indicate following device states:

Output K1 is closed if the output voltage is greater than 7kV.
Output K2 is closed if the device is switched off because of constant short circuit shutdown.

Options to adapt the device to customer specifications:

Output K1 may be configured to drive an usual LED. In this case the internal 5V-suplly voltage will be carried over a resistor to the clamps 21 and 24. The maximum current to drive the LED is 10mA.
The conditions which cause output switching may be free chosen.
