7. Functions
■
External input
Do assignments for functions (zero adjust or import reference) in
settings (main unit operations or communications settings) when
using external input (settings unused as factory default).
〈
NPN Type
〉
The external input terminal (pin number 4 for sensor input) should
be L level (less than 0.5 V, more than 10 ms) when executing
external input.
Do not connect the external input terminal to anything when you
are not using external input (it is pulled up by the power supply
voltage).
〈
PNP Type
〉
The external input terminal (pin number 4 for sensor input) should
be H level (
＋
V
ー
0.5V or more, 10ms or more) when executing
external input.
Do not connect the external input terminal to anything when you
are not using external input (it is pulled down to 0V).
■
Compatibility settings (RS232C type only)
Do these settings if compatibility with an older product's
communications format is required.
The sensor head type, threshold settings, and zero adjust
retention settings are initialized (returned to the factory default
settings for the format of the product being changed) after these
settings are changed.
Note that because this compatibility function relates to
transmitting commands and response formats, it is not for
response timing, etc.
Furthermore, because this is not compatible in regards
to the operation of the main unit, follow the operation
procedures of this product (MSU) to do main unit operations.
0: MSU format
1: PSU format
2: FSU format
3: PSU-36W format
4: PSU-40W format
■
Sensor head type settings
Select a sensor head type to connect to each channel.
0: Any sensor (set display at 1 V and 5 V)
1: MSU-PH-EA (-101.3 to 0.0 kPa)
2: MSU-PH-ER (-100.0 to 220.0 kPa)
3: MSU-PH-EM (-100 to 1000 kPa)
4: FS-R05 (-500 to 500 mL/min)
5: FS-R3 (-3.00 to 3.00 L/min)
6: FS-10 (0.00 to 10.00 L/min)
* After changing the sensor head type, the threshold value is
initialized to the value of the display range (maximum value +
minimum value)/2.
■
Any sensor settings
You can use a 1 to 5 V linear output sensor by setting the display
value at 5 V and display value at 1 V.
Size correlations, as well as positive/negative, are irrelevant for
display value at 5 V and display value at 1 V.
When using an optional sensor, do the various settings for the
optional sensor, and then set the sensor head type to optional
sensor.
1V
5V
Display value for 1 V
Display value for 5 V
Note: The span of the increments for the display are as below,
according to the span of the display range (the set value is
displayed, regardless of increments, for the display at 5 V and
the display at 1 V).
Span of display range = |display value at 5 V - display value at 1
V|
Span of display range 1 to 2000: increments of 1
Span of display range 2001 to 4000: increments of 2
Span of display range 4001 to 10000: increments of 5
Span of display range 10001 to 19998: increments of 10
