2.2 IAH - Setting of 100% input signal.
Valid selections are current 0.0...20.0 [mA], or voltage 0.0...10.0 [VDC].
For modules with a Pt100 input, the valid 100% temperature is
-99...+850 [°C].
2.3 UI - Selection of current / voltage input.
To select the current / voltage input the jumper on the PCB must be
moved.
For modules with a Pt100 input, this menu has no function.
Possible selections are I - [Current], or U - [Voltage].
3.0 Inb - Input B.
The input signal can be inverted by selecting the 0% value greater
than the 100% value.
3.1 IbL - Setting of 0% input signal.
Valid selections are current 0.0...20.0 [mA], or voltage 0.0...10.0 [VDC].
3.2 IbH - Setting of 100% input signal.
Valid selections are current 0.0...20.0 [mA], or voltage 0.0...10.0 [VDC].
3.3 UI - Selection of current / voltage input.
To select the current / voltage input the jumper on the PCB must be
moved.
Possible selections are I - [Current], or U - [Voltage].
4.0 OUt - Output.
The output signal can be inverted by selecting the 0% value greater
than the 100% value.
4.1 OL - Setting of 0% output signal.
Valid selections are current 0.0...20.0 [mA], or voltage 0.0...10.0 [VDC].
4.2 OH - Setting of 100% output signal.
Valid selections are current 0.0...20.0 [mA], or voltage 0.0...10.0 [VDC].
4.3 UI - Selection of current or voltage output.
The basic calibration data in the module differ according to the
selected output signal range meaning that the current output is current-
calibrated, and the voltage output is voltage-calibrated by the internally
mounted resistors.
To change between the output voltage in the range 0...1 and 0...10
VDC, the jumper on the PCB must be moved.
Possible selections are:
001 = current output in the range 0...10 mA
002 = current output in the range 0...20 mA (for instance 4...20 mA)
58
003 = voltage output in the range 0...500 mV
004 = voltage output in the range 0...1 V (for instance 0.2...1 V)
005 = voltage output in the range 0...5 V
006 = voltage output in the range 0...10 V
4.4 Or - Selection of overrange.
When ON has been selected, the output can exceed the selected
output span by ±3%, however only within the range 0...20.5 mA /
0...10.25 VDC.
When OFF has been selected, the output is limited to the selected
output span.
Possible selections are ON or OFF. [Permit overrange]
5.0 APP - Selection of application.
5.1 FUn - Selection of function.
Possible selections are:
001 = Addition of 2 analogue signals (P1*A + P2*B + P3).
002 = Subtraction of 2 analogue signals (P1*A - P2*B + P3) or
(P2*B - P1*A+P3).
003 = Max. selection of 2 analogue signals Max. (P1*A, P2*B) + P3.
004 = Min. selection of 2 analogue signals Min. (P1*A, P2*B) + P3.
005 = Multiplication of 2 analogue signals (P1*A*B) + P3.
006 = Division of 2 analogue signals (P1*A/B) + P3 or (P1*B/A) + P3.
007 = Root extraction / Raising to a power (P1(A or B)
A and B are the input signal spans for the A and B inputs respectively.
P1 and P2 are the scale factors multiplied on the A and B inputs
respectively. When the scale factors are 1, the input signal is scaled
to its full value. A scale factor of 0.5 will scale the input signal to half
its value. At the multiplication, division, root extraction and power
functions the scale factor must be set as P1. At the root extraction and
raising to a power P2 is the exponent. An exponent of 0.5 will result
in a square root function; an exponent of 2 will raise the input to the
second power.
P3 is a calculation offset set to values between 0 and 1 (0...100%)
and added to the present signal range of the output. If for instance the
output is set to a signal range of 10...20 mA, a P3 of 0.5 will result in
an extra offset of 50% of the output span. This means that the signal
range starts at 15 mA and starts to limit at 20 mA. At most calculations,
the calculation offset must be set to 0, but at complex calculations it
can be used for moving the range of the output signal range.
