1.3 IE - Internal / external signal limiter.
When - I - has been selected, the other analogue input is disabled, and
the signal limiting follows the set IL and IH values.
When - EL - has been selected, the high limit will follow the set IH
value, while the low limit will follow the other analogue input.
When - EH - has been selected, the low limit will follow the set IL
value, while the high limit will follow the other analogue input.
Possible selections are I - [Internal], EL - [External low], or EH -
[External high].
1.4 CH - Input.
The input that the output must follow.
Possible selections are A or B. [Input].
1.0 PAr for averaging. [Function no. 14]
1.1 AtI - Averaging time.
The time in seconds that the input is averaged before it is sent to the
output.
Valid selections are 0.1...999. [Seconds]
1.2 StS - Stack size.
Number of memories. The time between the updates of the output is
AtI divided by StS.
Valid selections are 1...14. [Memories]
1.3 CH - Input.
The input that is averaged before it is sent to the output.
Possible selections are A or B. [Input]
1.0 PAr for slope transmitter (Input A). [Function no. 15]
1.1 tAU - Time constant for exponential averaging of the input.
Valid selections are 0.00...999. [Seconds]
1.2 dIL - Smallest slope for 0% output value.
The slope in % of the input span that must correspond to the 0%
output signal.
A typical value is 0.0.
Valid selections are -99...100. [Per cent]
1.3 dIH - Greatest slope for 100% output value.
The slope in per cent of the input span that must correspond to the
100% output signal.
56
A typical value is 5.0, but the degree should be adapted to the present
application.
Valid selections are -99...100. [Per cent]
1.4 dt3 - Period in seconds * 1000 between the readouts of the input
value.
The period between the readouts of the input is set both in this menu
and in menu 1.5. The total period is the sum of menus 1.4 and 1.5 with
the limit of 0.02...3600 seconds.
A typical value is 0, but the period should be adapted to the present
application.
Valid selections are 0...003. [Seconds * 1000]
1.5 dt0 - Period in seconds between readouts of the input value.
The period between readouts of the input is set both in this menu and
in menu 1.4. The total period is the sum of menus 1.4 and 1.5 with the
limit of 0.02...3600 seconds.
A typical value is 1.0, but the period should be adapted to the present
application.
Valid selections are 0.02...999. [Seconds]
1.0 PAr for analogue multiplexer. [Function no. 16]
The input that must be transferred to the output must be selected by
the digital input.
Input A is selected by deactivating the digital input.
Input B is selected by activating the digital input.
1.1 P1 - Scale factor for input A.
A typical value is 1.0.
Valid selections are -99...999. [Factor]
1.2 P2 - Scale factor for input B.
A typical value is 1.0.
Valid selections are -99...999. [Factor]
2.0 InA - Input A.
The input signal can be inverted by selecting the 0% value greater
than the 100% value.
2.1 IAL - Setting of 0% 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 0% temperature is
-99...+850 [°C].
