2.6.4 Solenoi d outputs and am bie nt te m p era ture

If only one solenoid output is powered at a t im e, t hen there are no restric t ions and the single solenoid current may reach the maximum current according to the Elect ric al S pecificat ions over the whole temperature range.
7
But t he total solenoid current of simult aneously powered s olenoids depends on the ambient t emperature. Exceeding this current limit will t rip the overcurrent protecti on ci rcuit , the SD7 falls into the failure state and blocks all function. Solenoids can be powered simultaneously, i. e. with t wo channels with one solenoid eac h or with inverted solenoid outputs.
If s olenoids are powered with more vol t age than their nominal volt age and are so over-energized, then at fast switc hing-on, the overcurrent protect ion may t rip and the SD7 may fall into fail ure stat e and block all function.
The following graphics s hows t he maxim um allowed total solenoid current over ambient t emperature when both solenoids are powered at the same time.

4.1 Introduction

· All inputs and outputs have to be contacted through t he terminal screw block
· At the device front panel, there is a USB interfac e, t hrough which t he parameterisation and t he diagnostic s c an
be made by using the PC-Parameterisation software PA S O
· In the fac tory , the S D7-Elect ronics are adjusted with t he default values. The adjustment to the valves being
used, has to performed by t he user.
· Wandfluh c an c reate application specific parameters files in acc ordance to cust omer wish.

4.2 Description of the Function

T he SD7-Electronics has two channe ls. Each channel has a command value input and one or two solenoid outputs. The adjustable parameters are
organiz ed in function blocks , which are displayed in PAS O as small boxes . The following settings can be made per channel in these func t ion blocks:
52
52
58
59
60
61
63
64
68
69
70
Each channel is independent. Only the limits by the hardware are t o be c onsidered. For ex ample, if t he W andfluh­Elect ronic s has only two solenoid outputs . it's not possible to operat e two c hannels with each two s olenoids . In this c as e the maximum is at t wo channels with one solenoid output per c hannel or one c hannels with t wo s olenoid outputs per channel. The parameterisation software PASO automatically detects how many solenoids can be select ed with the c urrent setti ngs.
The ass i gnment of the analog and digital in- and outputs c an freel y be made by the user. Regarding inputs it is also possible to adjust a multiple allocation. That means digital and analogue inputs can be allocated to multiple channels (refe r to section " A s s ignment of t he inputs/ outputs " ). Digital in- and out puts which are set or reset by softwar e (ref e r to section "Configuration - Digital E/A" ) will be displayed with blue text color in the main window.

SD7_OperatingInstructions_
Operati n g Instructions to Amplifier Electronics SD7
The comm and value can be a voltage-, a c urrent-, a frequency- or a PWM-s ignal. t he s ignals are individually adjustable.
T he solenoid outputs includes a pulse-width-modulated current control with superimposed dither signal. These outputs c an control either proportional or switching solenoids. The current measurement can be switc hed on or off. The minimal and maximal solenoid currents or pulse widths can be adjusted separately. When using switching solenoids a fully adjustable power reduction func tion is available.
Parameters are set by means of the parameterising s oftware P A S O. Changed parameters are stored in a non­volatile memory in order to have t hem available after the Wandfluh-Electronics have been switched on again. The paramet erising s oftware PAS O provides to s ave t he set t ings an values of the parameter in a file, which always allows to do a download or an analysis.
Some function blocks are able to generate error messages. The function block "Error evaluation" (refer to sec tion
"Error evaluat ion" ) pick s up all error mes s ages. This function block manages the error handling of t he W andfluh-
68
Electronics. The process data are displayed online (r efer to section " A naly sis_S how values" ). This helps in c as e of support
88
and diagnost ics.

4.3 Characteristic opti m i sat i on

The SD7 electronics are provided with a possibili ty to optimis e the c harac teristic “Preset value input – s olenoid current out put”. The user is able to creat e a charac t eristi c (e.g. a l inearised characterist ic ) which matc hes his own application. The characteristic optimis at ion c an be turned on or off (refer to “Parameters_Solenoid driver ”).

4.5 Operati ng mode
The Wandfluh-El ect ronics have 2 operating modes. The following table describes, what c an be done in t he different operati ng modes and how t hey c an be acti vat ed:
The current operating mode is displayed in the status line (refer t o section "Starting of P A S O" ).
108

4.6 Analogue inputs

· The applied analogue signal is digit ised on analogue inputs 1 and 2 in the 10-Bit A / D c onverter and on analogue 3 and 4 (only E nhanced version) in the 16-Bi t A /D converter. Attention: By t he input range 4 . . . 20mA, t he resolution is < 10-Bit resp. 16-Bit!!
· Differen tial i np uts
All analogue inputs are different i al inputs . Differential inputs are used if the ground potential of t he ext ernal command value generator does not agree with the ground on the W andfluh-El ec t ronics . The differenti al inputs are not galvanically s eparated; they are made for ground potential differences up to 1.5V between the – (minus) connection of the different ial input and the 0V-ground of the Wandfluh-Elect ronics . If the different ial input is intended to use like an analogue input against ground, t he - (minus) connection of the differenti al input mus t be connected to the ground of the Wandfluh-Elec tronics. In this c as e please att end that t he solenoid current can cause a voltage drop between the Wandfluh-Elec t ronics and the power supply. It is recommended to connect the
- (minus) connection as near as possible to the power supply.
· Filtering
Each analog input can be individuall y filtered (refer to "Configuration_Filter for analog i nputs "). Thereby analog noise (e.g. voltage peaks) are attenuat ed. The filtering is done wit h t he function "exponential smoothing", where the speed / response time of the fil t er can be determined wit h t he parameter "smoothing factor". A high value at the smoothing factor results in a high degree of filtering, but a long response t im e, which will delayed the reading of the analog input. A small value at t he sm oothing factor results in a sm all degree of filtering, but a fast response time. So t he "smoothing factor" must be selec t ed as compromise between high degree of filtering and fast response time.

7.3 Parameter inconsistency

The parameter s ettings can be made via the PC-Parameterisation software PASO or via the fieldbus (only i f the Wandfluh-Elec tronics has t he fieldbus option). In any case, t he current parameter values will be dis played in the PASO
If a parameter value will be changed through the fieldbus, t his new value does not c orres pond with the displayed value in the PASO. In this c as e, t he following m essage appears:
If the answer is ”Yes ”, then the parameters will be read-in from t he W andfluh-El ect ronics . P oss ible open parameter windows in the PASO will be closed automatically. If a parameter value will be changed through the manual operati on terminal after the read-in of t he new parameters, t his mes sage will appear again.
If the answer is ”No”, then the displayed parameter values in the PASO do not c orrespond to t he c urrent parameter value on the Wandfluh-Electronics. This will be displayed in the status line in the field "Parameter inconsistency" (refer to sec tion "S tarting of PASO" ). If a parameter value will be changed through t he manual

Chara cte ri stic optimisation:
This menu enables the optimisat ion of the s ol enoid current adjus tment of DSV -E lectronics. A graphic is shown which represents t he characterist ic “Preset value (X-axis) – Solenoid current (Y-axis )”. The graphic c onsist s of 11 points, the first and the last point (100%) are preset.
The other graphic points can be adjus ted either by tracking with the mous e or by entering the value at t he numeric inputs. The res oluti on of the X-values is in %, those of the Y-values in 0.1 %. The X-values cannot be falling.
At shipping ex work (default s ett ings) t he preset value is transmit ted proport ionally t o t he solenoid c urrent (default characteristi c ). In this case the characterist ic “Preset value (X-ax is – Solenoid current (Y-axis )” i s li near. The same behaviour oc curs at any time when the characteristi c optimisati on is turned off.
By m odify ing the default linear charac teristic “Preset value (X-axi s) – S olenoid current (Y-axis )” e.g. a progress iv valve characteristic “Current - Flow/Press ure” can be compensated in such a way that a linear relation between preset value and Flow / P ressure is realised. The characteristic “Preset value (X-axis ) – Solenoid current (Y-axis )” in this case s hould be adjusted in the “opposite progress i ve” direction (refer to the example characterist i c below).
Additionally t he characterist ic optim isation must be turned on. This will be shown in t he PAS O-St atus li ne (refer to section "S t arting of PASO" ).
108
The solenoid current values are in the range Imin (0%) up t o Imax (100%). Imin and Imax are adjusted in t he m enu “Solenoid current ”. A t an input value whic h is between two graphic points, t he solenoid current is interpolated. If t wo or more preset values overlap, at t he c orrespondi ng Preset value the highest current value is c alculated.
In the case of an error i n t he characterist i c values, t he c haracterist ic optimisation is automat ically turned off.

7.13.3 Si g nal Re cordi ng

In this menu, various signals of the connected SD7-Electronics c an be recorded and analysed. The selection of the data t o be recorded takes place i n the menu " Signal ass ignment", which is selec ted through
the but ton "Signal assignment". In the "Offline - mode" it is not possi ble to record signals, it is poss ible, however, to process the recordin g parame ters (menu "Signal assignment").
Wit h the select ion "Start - s ingle" , it is possible to record up to 250 measuring values per measuring channel (maximum 4 channels). The m ax im um recording duration of the recording can be derived from the sc anning rate set multiplied with the number of the measuring values. The s canning rate is a mi nimum of 4ms. Because the first measured value is recorded at the point in time z ero (start), the las t measurement is sit uated one scanning s tep before the end of the measuring durati on.
With the selection "Scroll - continuos", it is possible to record up to 20000 measuring values per measuring channel (m aximum 4 channels ). Displayed will be always t he last 250 measuring values . A ll previous measured values can be displayed using a s croll bar. The sc anning rate is a minimum of 12ms. W it h a s mall sc anning rate, may the PC can not read in t he measured values fast enough. In this c ase, a mes s age appears and t he recording is finished.
The recording parameters (signal type, sc anning rat e, et c .) together with the parameters are saved on t he c ard and when saving to a file they are saved on the hard-disk . T he record ed measuring values are not s aved with the parameters. However, t here is t he possi bilit y of exporting the recorded measuring values (button "Ex port").
With the help of t he tim e c ursor, t he measuring values are displayed for every point in time. When changing t he mode "On-Line / Off-Line" and when terminating the P AS O, t he recorded measuring values are
lost.
