The use of solenoids necessitates a certain chronological sequence best clarified with the following terms:

7.1. Power-off pause
The power-off pause (in seconds) is the time between switching off the current and switching it on again.

7.2. ON period
This is the period (in seconds) between switching the current on and off again.

7.3. Cycle period
This is the sum of the ON period and the Power-off pause.

7.4. Duty cycle
The ratio between the ON and the cycle period is the relative ON period in %.

7.5. Cycling sequence
The cycling sequence (in seconds) is the single or periodically repeated joining of cycle period values of very different durations.

7.6. Response time
The response delay (in seconds) is the time between application of the current and initial movement of the plunger.

7.7. Stroke time
This time (in seconds) starts when the plunger begins to move from its initial position and ends when it reaches its limit of travel.

7.8. Pull-in time
The sum of Response time and Stroke time is the time required by the plunger to perform its work. Special measures in the circuit can shorten the pull-in time.

7.9. Drop-out delay
Drop-out delay (in seconds) is the time from current cut-out until the plunger starts to return to its initial position.

7.10. Return time
The return time (in seconds) is the time from the beginning of plunger return motion until it has reached its initial position.

7.11. Drop-out time
The sum of Drop-out delay and Return time is the drop-out time (in seconds).
