for details on setting
the detection width.
Setting 16: Frequency Detection 4
Output closes whenever the output frequency is equal to or above the detection level set in L4-03. The output opens when
the output frequency falls below L4-03 minus the hysteresis set in L4-04. As the detection level L4-03 is a signed value,
the detection works in the specified direction only.
