[TS19‐005] 4.1.3 Comparator function The comparator function compares the pressure that is applied to the stainless steel diaphragm of the Pressure Switch against a determination pressure value that is set in the Pressure Switch to turn it ON or OFF. Two comparator operating modes ‐ hysteresis mode and window comparator mode ‐ can be selected. Use the Setting Unit to set the comparator operating mode. Hysteresis mode operation In the Hysteresis mode the setting pressure can be set as the upper limit or lower limit, depending on the deadband setting. “Upper limit setting” When you select a positive number (including 0) for the deadband (⊿P), the comparator will operate with the setting pressure (P) as the upper limit. “Lower limit setting” When you select a negative number for the deadband (⊿P), the comparator will operate with the setting pressure (P) as the lower limit. Upper limit setting Lower limit setting FIG 4 Hysteresis mode operation Window comparator mode operation With operation in the Window comparator mode, comparator operation varies depending on how large or small the setting pressure (b) is relative to setting pressure (A). A deadband differential of 1% F.S. is automatically set internally between setting points (A) and (b). In the case that setting pressure (A) ≦ setting pressure (b), the comparator will be ON between (A) and (b). In the case that setting pressure (A) ...
[TS19‐005] Setting Point (A) Setting Point (b) FIG 6 Deadband of setting points (A), (b) 4.2 Setting Unit functions 4.2.1 Search function To establish infrared communication between the Setting Unit and Pressure Switch for measurement and setting, the Setting Unit must acquire the serial number of the Pressure Switch via the IR connection. In addition to acquiring the serial number, the Setting Unit at the same time also reads‐in the Pressure Switch’s pressure range and settings (pressure, deadband, output polarity, comparator operation settings). When communicating with another Pressure Switch, the serial number of that Pressure Switch must first be similarly acquired. 4.2.2 Setting Various Pressure Switch settings are performed with the Setting Unit’s setting functions. These are detailed in TABLE 11. In the setting operation, if the Pressure Switch is not recognized by the Setting Unit, the search function described in 4.2.1 is activated to establish the IR communication link between the Pressure Switch and Setting Unit. Pressure Switch settings are changed depending on the content of the various settings transmitted by the Setting Unit.

[TS19‐005] 4.2.3 Measurement (MEASURE) Measurement functions are described in TABLE 14. In the measurement mode, it is necessary to maintain constant infrared connection between the Pressure Switch and Setting Unit in order for the Setting Unit to acquire information from the Pressure Switch in real time. If infrared communication is disconnected for more than 1 minute, measurement mode will be cancelled but the connection information with the Pressure Switch will be retained in the Setting Unit so measurement can be resumed once communication is reestablished.

Infrared communication status, comparator operation, and pressure measurement values are displayed in real time. The detection pressure value set in the Pressure Switch is also displayed. Change pressure setting (SET) ...
[TS19‐005] 4.2.4 Memory (MEMORY) With the memory function, it is possible to save, edit, and create new setting values for the Pressure Switch. It is also possible to write the saved settings from one Pressure Switch to another Pressure Switch. The maximum number of storable data is 12. The stored values are set in the Pressure Switch with the search function and the Setting Unit and Pressure Switch infrared link. This connection cannot be made to a Pressure Switch with a different pressure range. 4.2.5 Configuration (CONFIG) With the device configuration setting function, set the environment of the Setting Unit. TABLE 15 describes the configuration settings. “BackLight” sets the brightness of the LCD backlight. Consumption current of the Setting Unit will increase with a brighter backlight setting and shorten battery usage time. Make settings that are appropriate to the operating environment.
