5.8 Introduction The digital amplifier module EL8 features leading edge technology. This electronic device meets the industrial standards for EMC. This ensures a high interference security and low interference emission. The performance characteristics are possible through the use of the most current microprocessor technology (32 bit floating point CPU) combined with other state of the art components. -

The information in this document is subject to change without notice. 7.2.3 EMC Devices EL8 series are class “A” equipment and therefore only suitable for industrial surroundings. The distance between a source of interference (device emitting interference) and an interference sink (a device under the influence of interference) is very important. -

Page 19: Ramp Function (R1.01 To R1.04)
This enables to change the direction of a valve as well as the scaling of the set point signals. Scaling for the set point is in the range of 0.00 … ± 4.00. Page 19 www.argo-hytos.com EL8_Instructions_Hinweise_Pokyny_19155_1en_de_cz_05/2022... -

If C1.00 = 3 or C1.00 = 4 (dff controller), than C1.13 is the amplification of the dff controller and C1.16 is the P-amplification of the remaining PT1-I-DT1 controllers. C1.15 will be without effect in these cases Page 20 www.argo-hytos.com EL8_Instructions_Hinweise_Pokyny_19155_1en_de_cz_05/2022... -

8.5.3 Operation mode (E00) This parameter is predetermined by selection of the module version. For modules version EL8 2-01 it is “1” and for modules version EL8 2-02 it is “2”. 8.5.4 Selection of set point (E15) This parameter is used in order to select the type of Analog set point. Either a voltage input (0 … ± 10 V) or a current input can be selected. If the current input is selected than the measuring resistance of 250 Ohm is automatically activated. -

Through combination of hardware and software functions for the actual value adjustment guarantees highest resolution and precision. Therefore, the advantages to a system with analogous adjustment using potentiometers are obvious. Adjustment: CAUTION Activate the “enable” signal. If C1.09 = 10, 11 or 12, d1.11 will not show any values < 0.000. Page 28 www.argo-hytos.com EL8_Instructions_Hinweise_Pokyny_19155_1en_de_cz_05/2022... -

By setting the threshold value of the comparator (C1.21 and C1.22) = 0, the “S1.01” input can be used directly to activate the controller. This allows to activate the controlling by to external factors. C1.23 does not have any function when the “switching controller” is activated.
