4.2 Functional characteristics
Functional characteristics Explanation
VSR display value
The highest measured value is always displayed. The display value is reset
to 0 by deleting the max. value and when resetting into the go (good) state.
Delay Enable On time
Runs down when starting the unit and after opening the enable input; during
this time there is no evaluation of the vector shift
Reset time
When a reset time 8
dof
8 is running, it is always counted down in the
display (shortest one first)
Reset
Use the Reset key or interrupt the control voltage for > 2 s (comply with reset
delay)

MIN / MAX values All min and max values are saved zero-voltage maintained (non-volatile).
Tripping time
(only with feedback
contacts connected)
Connecting the feedback contacts enables measuring the shut-down time.
After a tripping time with the test button it is displayed until a button is
pressed again with a resolution of up to 1ms.
Total shut-down time = Tripping time + Response time
