Eliwell ECH 200BD "Adaptive" User Manual

ECH 200 BD
10/76
If input AI3 is defined as a 4...20 mA input, the scale bottom value of the pressure input is also signfiicant: Pa H09,
maximum input value; sets the corresponding value to a current of 20 mA
4.3 Configuration of digital inputs
There are 5 voltage-free digital inputs, which will henceforth be identified as ID1…ID5.
AI1, AI2 e AI4 may be added to these if they are configured as digital inputs (through parameters Pa H05, Pa H06, and Pa
H08).
A total of 8 digital inputs is thus available.
The polarity of digital inputs is determined by the parameters listed below:
Value
Parameter Description
0 1
Pa H10 Polarity of digital input ID1 Active if closed Active if open
Pa H11 Polarity of digital input ID2 Active if closed Active if open
Pa H12 Polarity of digital input ID3 Active if closed Active if open
Pa H13 Polarity of digital input ID4 Active if closed Active if open
Pa H14 Polarity of digital input ID5 Active if closed Active if open
Pa H15 Polarity of input AI1 (configured as digital) Active if closed Active if open
Pa H16 Polarity of input AI2 (configured as digital) Active if closed Active if open
Pa H17 Polarity of input AI4 (configured as digital) Active if closed Active if open
Inputs ID1 and ID2 cannot be configured and fulfill the following functions:
• ID1 : High pressure input
• ID2 : Low pressure input
The functions of the other inputs may be configured using parameters:
• AI1, AI2: (Refer to Analogue inputs: configuration table)
• ID3, ID4, ID5 and AI4: as shown in the table below

If more than one of the parameters appearing in table 3 is configured with the same value, the function will be called up
in response to at least one of the inputs.
