The channel allows to set a bound around the Vset or Iset values. If the Vmeasure or Imeasure value leaves this range, an Event Voltage Bounds or Event Current Bounds is set. (Vset - Vbound) <= Vmeasure <= (Vset + Vbound) (Iset -Ibound) <= Imeasure <= (Iset + Ibound)
The channel is working as constant current source: Imeasure ≈ Iset, Vmeasure < Vset.
The channel is working as constant voltage source: Vmeasure ≈ Vset, Imeasure < Iset.
A Current Trip is an overcurrent that leads to a shut down of the High Voltage without ramp. A Current Trips happens:
A Delayed Trip can turn off the High Voltage with or without ramp after a configurable trip timeout. Delayed Trip is only possible for modules with Constant Current regulation.
The Delayed Trip is configured with the Set Current Trip dialog.
Note: The Voltage Ramp Speed is limited to 1 % if Delayed Trip is enabled.
Note: Devices with two current measurement ranges permanently switch to the high current range when Delayed Trip is enabled.
The mode Kill Enable provides a higher safety.
The following Events shut down the High Voltage without ramp in mode Kill Enable:
Note: Devices with two current measurement ranges permanently switch to the high current range in mode Kill Enable.
Note: The Voltage Ramp Speed is limited to 1 % in mode Kill Enable.
Note: The Delayed Trip function is only available in mode Kill Disable.
