Over Or Under Speed

Output energizes in the over speed condition and de-energizes in the under speed condition.

If the time between input pulses is longer than the set time, (or if pulses stop,) under speed is indicated. If the time between pulses is shorter than the set time, over speed is indicated. The time is adjustable.

Notes

• Light time and dark time is limited by the control's response time.
• Only over or under speed can be detected with a single control, but not both.
