Hysteresis Range For On/Off Control - FE PXR4 Operation Manual

[Description]
• To select the ON/OFF control (two-position control), set
to 0.0. It is not necessary to set
• When the hysteresis range (Range of ON/OFF control) is
too small, the output may switch the ON/OFF frequently.
(This may affect the life of the device to be controlled,
especially when contact output is selected.)
• The unit of the set value of this parameter is °C or °F
(engineering unit). The setting range varies according to
the measured range of input.
