Example: Setpoint at 10 psig. On a rise in pressure, the timing circuit opens at 10 psig and time out ends. On a fall in pressure, the timing circuit energizes at 6 psig to 9 psig and the time out begins. If the pressure fails to reach 10 psig within the 60 second time delay, the main contacts open, which shut down the controlled equipment.
