If a mechanical relay or contactor is switching power to the load, a longer

cycle time may be desirable to minimize wear on the mechanical compo-

nents. Typical life of a mechanical relay is 100,000 cycles.

Range: 0.1 to 999.9 seconds Default: 5.0 seconds

Alarm Low: Represents the low process alarm or low deviation alarm. This para-

meter will not appear if [`Ot2] is set to no or [`Con].
