EATON XV-440-12TSB-1-10 touch panel

More control inputs have the following functions: "Command value valid": Enabling of the parameter set addressed by the current call-up (H active) "Enable": Activation of the outputs (acknowledgment of the fault message with low→high edge) The command value can be preset via digital command value call-ups [5] and/or via analog inputs [1]. The analog input AI4 (b14/b16) is to be used for the command value presetting of ±10 V, the analog input AI6 (b22/b24) for any command value presetting from 4 to 20 mA. Command values from 0 to +10 V (12...20 mA) control solenoid B. Command values from 0 to –10 V (4...12 mA) control solenoid A.

The digital command value is added to the analog command 

value with the correct sign, according to the set call-up. The command value inputs can be varied by means of software in the signal level. Apart from the internal ramp generation option, you can also influence the ramp for "up" and "down" from external signals with correct total and correct sign by means of the AI2 (b6/b8) and AI5 (b18/b20) analog inputs. For the valves, the software configures a step function generator [8] for the realization of the overlap jump if an overlapped control spool is selected.

Enable and error messages

 The control is activated by the H level at the enable input. If no command value call-up is active, the digital call-up 0 is set. Error logics [13] identify any cable break of the command value input for 4 to 20 mA as well as an inactive enable input. If there is an error, a fault message is output to (d22) by means of a low signal and displayed visually by the "OK" LED (OK goes out) on the front plate. It is possible to configure the enable so that an inactive enable input is not displayed as error.
