Graph Calculation process for the sequence centre value 1. The illuminated display permits easy handling and programming, even in difcult situations. 200 It’s easy to integrate into a BMS system, and Modbus communication is standard. Hydrovar supports various types of sensors because of an enhanced input signal range (4-20mA, 0-20mA, 0-10Vdc). Or for a second sensor for safety reasons. Available Hydrovar versions include Single and Master. 3 While as many as 8 Master Hydrovar pumps can be connected to The extended manual control mode has different fixed speed values that are changeable with an external contact. As you would expect, retrofitting is possible for all existing standard asynchronous motors that are suitable for VFD operation. Single pump Using one single inverter for speed controlled function Master inverter. All hydraulic control functions are included, which means addi- tional external controllers are not required. The motor fan optimizes cooling, depending on the power and speed of the pump itself.http://www.bouwdata.net/evenement/bosch-injection-pump-service-manual And, of course, maintenance intervals are longer be- cause of less stress to the pump and motor.This is particularly the case when a centrifugal pump is running at partial loads. For instance: By operating a closed loop HVAC system in accordance with system curve compensation, you are lowering the required pressure in the system. Example: Circulation pump with nominal power in partial load operation.The company is wholly owned by the ITT Corporation of White Plains, New York,. Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates. There's no need for an external control panel when using Hydrovar. Advanced programming features allow optimzing the Hydrovar for almost any duty condition. With energy savings of up to 70 on partial loads alone, the typcial investment payback period is less than two years depending on energy costs and pump operating times. All modifications must be done by qualified technicians. Warning that failure to observe the precaution may cause electric shock Warning that failure to observe the precaution may cause personal injury or damage to property. In addition to these operating instructions please pay attention to universal safety and accident prevention regulations. Page 6 All work, carried out on the HYDROVAR, may only be performed by qualified and authorized staff. Furthermore, take care not to short circuit the neighbouring components when connecting the external control wires. All cable ends which are not in use have to be isolated. The HYDROVAR contains electronic safety devices which switch off the control element in the event of a fault, whereby the motor has zero current but remains energised and comes to a halt. The motor can also be halted by mechanical blocking. Avoid serious impacts NOTICE. Dispose of all packing materials and the HYDROVAR unit in accordance with local regulations.http://gfenergies.com/images/buell-owners-manual.pdf For more detailed information about the recycling of this product, please contact your local authority, your waste disposal service provider or the outlet where you purchased the product. Page 8 2 System design The following diagrams show typical SINGLE and multi-pump systems using the HYDROVAR. Connection can be made directly to a water supply. In such a case, the use of a low pressure switch on the suction is recommended. SINGLE pump layout (1) (2) (3) 2. Page 9 3 Product overview 3.1 Hardware configurations The HYDROVAR modular concept basically consists of two main parts: the power unit and the control card. In its BASIC configuration (consisting of only the power unit) the HYDROVAR can be used as so called BASIC Inverter. In general each of the pumps needs to be equipped with a HYDROVAR unit. All the units are connected via the RS485 interface and communicate via the standard MODBUSprotocol (9600 Baud, RTU, N81). To realise a fully controlled system at least one MASTER Inverter is needed, the remaining pumps could be fitted just with a BASIC Inverter. Page 11 To increase the operating reliability of such a system, also a second MASTER Inverter is recommended: Full-featured possibility: Each pump is equipped with a MASTER Inverter In this mode it is possible to run all pumps in cascade serial mode and synchronous mode as well. This configuration allows each pump of the system to become the lead pump. This also ensures a proper operation if one MASTER Inverter fails. In this case another HYDROVAR takes control. Page 12 3.2.4 Cascade Relay (not for SINGLE version) One pump is fitted with a HYDROVAR MASTER Inverter and up to 5 slave pumps can be switched ON and OFF on demand. For this purpose an additional relay card including 5 relays is attached to the MASTER Inverter. However an external switchboard is needed for all the motor relays as the relays in the HYDROVAR are not able to switch the pumps directly (just used as control contacts).http://fatheragneliti.com/wp-content/plugins/formcraft/file-upload/server/content/files/16292e172e79aa---98-nissan-altima-service-manual.pdf Lifting aids must have the proper dimensions.

Page 20 7 Modules Regarding the application the specific configuration for the HYDROVAR can be chosen. When using a SINGLE or MASTER configuration the power unit is fitted with an additional control card (4) (2) Filter card (not available for HV4.150-4.220, standard is class A) Ensures EMC compliance for domestic environments. Page 25 9 Electrical installation and wiring All installations and maintenance has to be performed by properly trained and qualified personnel with proper tools!! Use personal protection equipment. In case of a failure, the electrical power has to be disconnected or switched off. Wait at least 5 minutes for capacitor discharge before servicing the HYDROVAR. Signal cables Control and signal cables should be screened types to prevent disturbances from outside. Page 27 Motor cables To ensure the EMC compatibility and minimize noise level and leakage currents, keep the motor cable as short as possible (use shielded cables only if the total length exceeds 1.5 meters). Additional component line choke (coil) Line coils are available as an option and should be mounted between the HYDROVAR and the main fuse. The Line coil should be as near as possible to the HYDROVAR (max. 30cm). Page 28 9.4 Wiring and connections Remove the screws holding the top cover of the HYDROVAR. Lift off the top cover. In this case for all MASTER Inverters the below shown dip-switch on the power unit must be set to address 1 (default setting). In general the default settings should not be changed and remain in default position. NOTE: Due to the additional filter capacity the earth leakage current will increase, if the filter is active. Page 37 9.4.5 Control unit Regarding the hardware configuration of the HYDROVAR two different control cards are available.www.emcogroupus.com/userfiles/files/conn-organ-service-manual-pdf The control unit of the HYDROVAR MASTER Inverter basically consists of the control card and the additional boards which are connected to the control card via slot connectors. This configuration is able to support all special software features and optional boards. The second available control card included in the HYDROVAR SINGLE Inverter is developed just for SINGLE pump operation. Page 38 Control terminals All control cables connected to the control card have to be screened (See chapter 9.3 recommended cable types). In ACTUATOR mode it is possible to switch between two different frequencies by the digital inputs. The connected input signals (current or voltage) are proportional to the frequency. Both Status-Relays on the control card can be used regarding the programmed configuration. Page 44 9.4.5.2 Relay Card This optional component can be used only in combination with a HYDROVAR MASTER Inverter. The Relay Card is connected to the control card using connection slot X6 (See chapter 9.4.4.1). Terminal block Notice: When using the relay contacts for switching external contactors, a corresponding RC-snubbercircuit or varistor is necessary, to prevent disturbances arising during a switching action of the relay. Page 45 Connection example: The following wiring diagram shows a standard cascade control system where the HYDROVAR is fitted with an additional Relay Card, in selected mode Cascade Relay. Page 47 Control Terminals All control cables connected to the control-unit have to be screened (See chapter 9.3 recommended cable types). Both Status-Relays on the control card can be used regarding the programmed configuration. Page 49 10 Programming Read and follow the operating instructions carefully before you start programming to prevent incorrect settings which will cause malfunction.

Page 60 60 SUBMENU SETTINGS Before entering the submenu settings these instructions must be read carefully to prevent incorrect settings which will cause malfunction. All parameters can also be set during operation. Therefore different parameters in the extended submenu should be used only by trained and qualified persons. Page 62 Actuator: (For SINGLE pump operation only!) The actuator mode has to be used if a fixed speed setting is required or an external speed signal is connected and the HYDROVAR is just used like a standard VFD. In this case, the internal controller is shut off, so the HYDROVAR does not control the set value but runs the connected motor at a frequency proportional to the input signal which is connected to the analogue inputs or is set directly on the HYDROVAR.

The standard setting is according to the nominal frequency of the connected motor. OFF Possible settings: Reduction of the maximum output current G OFF, 85, 75, 50 If a motor with lower nominal power is used, the maximum output current should be adjusted accordingly. The reduction of the maximum output current also affects the overload-detection. LIMIT OFF Possible settings: 0291 0291 CURR. The setting determines the output-frequency where the set pressure starts to be increased. It is not possible to install two different transducer types because main configuration is the same for all connected sensors. Page 77 0500 S 0500 SUBMENU SEQUENCE CNTR. The switch interval is used for HYDROVAR MASTER Inverters only (connected via the RS-485 interface) by using operation mode Cascade Serial or Cascade Synchron. In such a case you have to select if either the MASTER or the BASIC Inverters should be switched on first. ON- all MASTER Inverters in the system are released (unless it is stopped by a failure or manually) before the first BASIC Inverter gets released. Page 82 0600 0600 SUBMENU ERRORS 0605 0605 MIN.

We’re 12,000 people unified in a common purpose: creating innovative solutions to meet our world’s water needs. Developing new technologies that will improve the way water is used, conserved, and re-used in the future is central to our work. We move, treat, analyze, and return water to the environment, and we help people use water efficiently, in their homes, buildings, factories and farms. In more than 150 countries, we have strom, long-standing relationships with customers. Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates. To avoid or simplify the preparation and manageme nt of relatively complex input data files for flow problems, and to graphica lly displ ay the final simulation results, we developed the HYDRUS1D interactive graphics-ba sed us er-friendly interface for the MS Windows environment. The HYDRUS1D interface is directly connec ted to the HYDRUS computational pr ograms. The software package is distributed on a CD- RO M containing all necessary files needed to run the interface, the input and out put files of various examples discussed in this report and several other examples. The software packag e can also be freely downloaded from www.hy drus2d.com (orm ww w.pc-prog ress.cz ). A general overview of the HYDRUS1D graphics-based interface is described in Part B of this manual. We note that in addition to the detailed descriptions in this section, extensive on-line help files are also ava ilable in each module of the user interfac e. The flow equation i ncorporates a sink term to a ccount for water uptake by plant roots. The flow equation may also consider dual - porosity ty pe flow in which one fraction of the water con ten t is mobile a nd another fraction immobile, or dual - permeability type flow involving two mobile regions, one representing the ma tr ix an d one the macropore s. The heat t ransport equation considers t ransport due to conduction and convection with flowing water. Coupled water, vapor, and energ y transpo rt can be consider ed as well. The solute transport equations consider ad vective-dispersive transpor t in the liquid phase, as well as diffusion in the gaseous phase. The t ransport equations also include provisions for nonlinear nonequilibrium reactions between the solid and liquid phases, l inear equilibrium reactions be tween the liquid and g aseous phases, zero-order production, and two first-order degra dation reactions: one which is independent of ot her solutes, and one which provides the coupling between sol utes invol ved in sequential first-order decay reactions. Phy sical nonequilibrium solute t ransport can be accounted for by assuming a two-region, dual-porosity ty pe formulation which partitions the liquid phase into separate mobile and immobile regions. HYDRUS -1D further incorporates modules simulating carbon dioxide production and major ion solut e movement. The CO 2 transport processes include diffusion in both the liquid and gas phases and ad vection in the liquid phase. The CO 2 production model is described i n detail. The model accounts for equili brium chemical reac tions between these components such as complexation, cation ex change and precipitation-dissolution. For the precipitation- dissolution of calcite and di ssolution of dolomite, either equilibrium or multi component kinetic expressions are used which include both forward and back reactions. Other dis solution- precipitation reactions considered include gy psum, hy dromagne site, nesquehonite, and sepiolite. Since t he ionic s trength of soil solutions can vary considerably with ti me and space and often reach high values, both modified Deby e-Huckel and Pit zer expressions were incorporated into the model as options to calculate single ion activities. Vapor movement is often an important part of the total water flux when the soil is relatively dry.Overall water flow in (2.3) is given as the sum of isothermal liqui d flow, isothermal vapor flow, gravitational liqui d flow, thermal liquid flow, and thermal vapor flow.We will use here the subscript m t o represent fractures, M and ?? F in (d) are water contents of the matrix and macropore (fract ure) regions, respecti vely, and. M,mo, ? M,im, and ?? F in (e) are water contents of the mobile and immobile flow regions of the matrix domain, and of t he macropore (fractur e) domain, r espectively; c are concentrati ons of correspondi ng regions, with subscript s having the same m eaning as for water contents, while S is the t otal solut e content of t he liquid phase. All root water uptake is assumed to be taken out of the matrix domain in the current HYDRUS version and thus S f is assumed to be zero. 2.2. Root W ater Uptake 2.2.1. Root W ater Uptake W ithout Compensation The sink term, S, is defined as the volume of water removed from a unit volume of soi l per unit time due to plant water uptake. For h h 4 (the wilting point pressure head), water uptake is also assumed to be zero. Water upt ake is considered opt imal between pressure heads h 2 and h 3, whereas for pressure head between h 3 and h 4 (or h 1 and h 2 ), water uptake decreases (or increases) linearly with h.Simi larly, h ? 50 represents t he osmotic head at which the water ex traction rate is reduced by 50 during conditions of negligible water stress. Thi s simplification seems justified wh en saturated or near-saturated conditions occur for only relatively short periods of time. Normalizing the uptake distribution ensures that b ( x ) integr ates to unity over the flow doma in, i.e., () 1 R L b x dx ? ? (2.16) Fig ure 2. 3. Schematic of the potent ial water upt ake distributi on function, b ( x ), in the soil root zone.For annual vegetation a growth model i s required to simulate the change in rooting depth with time.However, some red uction in potential transpiration will occur below this threshold value, although smaller than for water uptake without compensation. The parameters ?, n and l in HYDRUS are considered to be empirica l coefficients af fecting the sha pe of the hy draulic functions.An ex ample of composit e retention and hy draulic conductivity functions for two overlapping porous media is shown in Figure 2.5. Note that the pressure head axes are on a log scale, which causes the near-saturated values to be significantly enlarged. The fracture domain in this example represents only 2.5 of the entire pore space, but accounts for almost 90 of the hy draulic conductivity close to saturation.While such a simplification may be acceptable for many flow simulations, other cases require a more realistic description invol ving hysteresis in the soi l hy draulic properties.The adopted procedure for modeling hy steresis in the retention function requires that both the main drying and main wetting curves are known (Fig. 2.4). These two curves are described with (2.32) using the parameter vectors (.We further assume Figure 2.7. Example of a water r etention cur ve showing hy steresis. Shown are t he boundary wetting curve,.According to the hy steresis model, dry ing scanning curves are scaled from the main drying curve, and wetting scanning curves from the main wetting curve. Subs tituting this reversal point into (2.59), and assuming that.The scaling factor ? ? for a particular scanning curve can be obtained by substi tuting the reversal point ( ? ?, h ? ) and the full saturation point (.Substit uting the reversal point ( h ?, K ? ) and the saturation point (0, K s ) into (2.66) and solving for ? K y ields One of these involves the soil-air interface, which is exposed to atmospheric conditions. The potential fluid flux across this interface is controlled ex clusively by external conditions. However, the actual flux depends also on the prevailing (transient) soil moi sture conditions near the surface. The soil surface boundary condition may chang e from a prescribed flux to a prescribed head type condition (and vice-versa).One options in HYDRUS is to assume that any excess water on the soi l surface above zero will be immediately r emoved.
