7 1. INTRODUCTION EVD evoluion win is a conroller feauring wo drivers for double pole sepper moors ha independenly manages wo elecronic expansion valves. I is designed for DIN rail assembly and is fied wih plug-in screw erminals. Each driver conrols refrigeran superhea and opimises he efficiency of he refrigeran circui, guaraneeing maximum flexibiliy, being compaible wih various ypes of refrigerans and valves, in applicaions wih chillers, air-condiioners and refrigeraors, he laer including subcriical and ranscriical CO 2 sysems. I feaures low superhea (LowSH), high evaporaion pressure (MOP), and low evaporaion pressure (LOP) proecion, and can manage, as an alernaive o superhea conrol, special funcions such as he ho gas bypass, evaporaor pressure regulaion (EPR) and conrol of he valve downsream of he gas cooler in ranscriical CO 2 circuis. The conroller can drive an elecronic expansion valve in a refrigeran circui wih Digial Scroll compressor, if inegraed wih a specific CAREL conroller via LAN. In addiion, i feaures adapive conrol ha can evaluae he effeciveness of superhea conrol and if necessary acivae one or more uning procedures. As regards nework conneciviy, he conroller can be conneced o eiher of he following: a pco programmable conroller o manage he conroller via plan, LAN and R85/Modbus ; a PlanVisorPRO supervisor via R85/Modbus. In his case, On/Off conrol is performed via digial inpu 1 for driver A and via digial inpu 2 for driver B, if suiably configured. As well as regulaion sar/sop, digial inpus 1 and 2 can be configured for he following: - valve regulaion opimizaion afer defros; - valve forced open (a 100%); - regulaion backup; - regulaion securiy. The las wo possibiliies refer o he behaviour of he driver when here is no communicaion over he plan or LAN, R85/Modbus nework (see chap. 6). Anoher possibiliy involves operaion as a simple posiioner wih 4 o 20 ma or 0 o 10 Vdc analogue inpu signal for driver A (inpus and respecively) and wih 4 o 20 ma signal for driver B (inpu ). EVD evoluion win comes wih a LED board o indicae he operaing saus, or a graphic display (accessory) ha can be used o perform insallaion, following a guided commissioning procedure involving seing jus 4 parameers for each driver: refrigeran, valve, pressure sensor, ype of main conrol (chiller, showcase, ec.). The procedure can also be used o check ha he sensor and valve moor wiring is correc. Once insallaion is complee, he display can be removed, as i is no necessary for he operaion of he conroller, or alernaively kep in place o display he significan sysem variables, any alarms and when necessary se he conrol parameers. The conroller can also be seup using a compuer via he service serial por. In his case, he VPM program (Visual Parameer Manager) needs o be insalled, downloadable from hp://ksa. carel.com, and he USB-LAN converer EVDCNV00E0 conneced. Only on R85/Modbus models can insallaion be managed as described above by compuer, using he serial por (see paragraph 2.6) in place of he service serial por. The universal models can drive all ypes of valves, while he CAREL models only drive CAREL valves. 1.1 Models Code Descripion EVD0000T00 EVD evoluion win universal (LAN) EVD0000T01 EVD evoluion win universal (LAN) pack of 10 pcs.

21 Noe ha conrol is calculaed as he sum of hree separae conribuions: proporional, inegral and derivaive. he proporional acion opens or closes he valve proporionally o he variaion in he superhea emperaure. Thus he greaer he K (proporional gain) he higher he response speed of he valve. The proporional acion does no consider he superhea se poin, bu raher only reacs o variaions. Therefore if he superhea value does no vary significanly, he valve will essenially remain saionary and he se poin canno be reached; he inegral acion is linked o ime and moves he valve in proporion o he deviaion of he superhea value from he se poin. The greaer he deviaions, he more inense he inegral acion; in addiion, he lower he value of T (inegral ime), he more inense he acion will be. The inegraion ime, in summary, represens he inensiy of he reacion of he valve, especially when he superhea value is no near he se poin; he derivaive acion is linked o he speed of variaion of he superhea value, ha is, he gradien a which he superhea changes from insan o insan.

The Synchronisaion procedure allows he driver o perform a cerain number of seps in he suiable direcion o realign he valve when fully opened or closed. Noe: realignmen is in inrinsic par of he forced closing procedure and is acivaed whenever he driver is sopped/sared and in he sandby phase; he possibiliy o enable or disable he synchronisaion procedure depends on he mechanics of he valve.

31 7. PROTECTORS Noe: he HiTcond and Reverse HiTcond proecors can only be acivaed if EVD Evoluion win is operaing as a single driver. See Appendix 2. These are addiional funcions ha are acivaed in specific siuaions ha are poenially dangerous for he uni being conrolled. They feaure an inegral acion, ha is, he acion increases gradually when moving away from he acivaion hreshold. They may add o or overlap (disabling) normal PID superhea conrol. By separaing he managemen of hese funcions from PID conrol, he parameers can be se separaely, allowing, for example, normal conrol ha is less reacive ye much faser in responding when exceeding he acivaion limis of one of he proecors. When he superhea value falls below he hreshold, he sysem eners low superhea saus, and he inensiy wih which he valve is closed is increased: he more he superhea falls below he hreshold, he more inensely he valve will close. The LowSH hreshold, mus be less han or equal o he superhea se poin. The low superhea inegraion ime indicaes he inensiy of he acion: he lower he value, he more inense he acion.

Noe: he alarm signal is independen from he effeciveness of he proecor, and only signals ha he corresponding hreshold has been exceeded. If a proecor is disabled (null inegraion ime), he relaive alarm signal is also disabled. Each proecor is affeced by he proporional gain parameer (K) for he PID superhea conrol.

The MOP proecion hreshold is applied as a sauraed evaporaion emperaure value so ha i can be easily compared agains he echnical specificaions supplied by he manufacurers of he compressors. The proecor is acivaed so as o preven oo high evaporaion emperaures from causing an excessive workload for he compressor, wih consequen overheaing of he moor and possible acivaion of he hermal proecor.

To reduce he evaporaion emperaure, he oupu of he refrigeraion uni needs o be decreased. This can be done by conrolled closing of he elecronic valve, implying superhea is no longer conrolled, and an increase in he superhea emperaure. The proecor will hus have a moderae reacion ha ends o limi he increase in he evaporaion emperaure, keeping i below he acivaion hreshold while rying o sop he superhea from increasing as much as possible. Normal operaing condiions will no resume based on he acivaion of he proecor, bu raher on he reducion in he refrigeran charge ha caused he increase in emperaure.

B When he evaporaion emperaure rises above he MOP hreshold, he sysem eners MOP saus, superhea conrol is inerruped o allow he pressure o be conrolled, and he valve closes slowly, rying o limi he evaporaion emperaure. As he acion is inegral, i depends direcly on he difference beween he evaporaion emperaure and he acivaion hreshold. The more he evaporaion emperaure increases wih reference o he MOP hreshold, he more inensely he valve will close.

This is because following such alarms, he user may wan o proec he uni by sopping he flow of refrigeran or swiching off he compressor.

Proecor alarms The alarms corresponding o he LowSH, LOP and MOP proecors are only acivaed during conrol when he corresponding acivaion hreshold is exceeded, and only when he delay ime defined by he corresponding parameer has elapsed. If a proecor is no enabled (inegral ime= 0 s), no alarm will be signalled. If before he expiry of he delay, he proecor conrol variable reurns back inside he corresponding hreshold, no alarm will be signalled. Noe: his is a likely even, as during he delay, he proecion funcion will have an effec. If he delay relaing o he conrol alarms is se o 0 s, he alarm is disabled. The proecors are sill acive, however. The alarms are rese auomaically. Low sucion emperaure alarm The low sucion emperaure alarm is no linked o any proecion funcion. I feaures a hreshold and a delay, and is useful in he even of probe or valve malfuncions o proec he compressor using he relay o conrol he solenoid valve or o simply signal a possible risk. In fac, he incorrec measuremen of he evaporaion pressure or incorrec configuraion of he ype of refrigeran may mean he superhea calculaed is much higher han he acual value, causing an incorrec and excessive opening of he valve. A low sucion emperaure measuremen may in his case indicae he probable flooding of he compressor, wih corresponding alarm signal. If he alarm delay is se o 0 s, he alarm is disabled. The alarm is rese auomaically, wih a fixed differenial of 3 C above he acivaion hreshold.

These cover he mos common problems and are provided wih he aim of offering an iniial response for resolving he problem. PROBLEM CAUSE SOLUTION The superhea value measured is incorrec The probe does no measure correc values Check ha he pressure and he emperaure measured are correc and ha he probe posiion is correc. Check ha he minimum and maximum pressure parameers for he pressure ransducer se on he driver correspond o he range of he pressure probe insalled. Check he correc probe elecrical connecions. Liquid reurns o he compressor during conrol Liquid reurns o he compressor only afer defrosing (for muliplexed showcases only) Liquid reurns o he compressor only when saring he conroller (afer being OFF) The superhea value swings around he se poin wih an ampliude greaer han 4 C The ype of refrigeran se is incorrec The ype of valve se is incorrec The valve is conneced incorrecly (roaes in reverse) and is open The superhea se poin is oo low Low superhea proecion ineffecive Saor broken or conneced incorrecly Valve suck open The valve opening a sar-up parameer is oo high on many showcases in which he conrol se poin is ofen reached (for muliplexed showcases only) The pause in conrol afer defrosing is oo shor (for MaserCase, MaserCase 2 and mpxpro only) The superhea emperaure measured by he driver afer defrosing and before reaching operaing condiions is very low for a few minues The superhea emperaure measured by he driver does no reach low values, bu here is sill reurn of liquid o he compressor rack Many showcases defrosing a he same ime The valve is significanly oversized The valve opening a sar-up parameer is se oo high The condensing pressure swings The superhea swings even wih he valve se in manual conrol (in he posiion corresponding o he average of he working values) The superhea does NOT swing wih he valve se in manual conrol (in he posiion corresponding o he average of he working values) The superhea se poin is oo low Check and correc he ype of refrigeran parameer. Check and correc he ype of valve parameer. Check he movemen of he valve by placing i in manual conrol and closing or opening i compleely. One complee opening mus bring a decrease in he superhea and vice-versa. If he movemen is reversed, check he elecrical connecions. Increase he superhea se poin. Iniially se i o 12 C and check ha here is no longer reurn of liquid. Then gradually reduce he se poin, always making sure here is no reurn of liquid. If he superhea remains low for oo long wih he valve ha is slow o close, increase he low superhea hreshold and/or decrease he low superhea inegral ime. Iniially se he hreshold 3 C below he superhea se poin, wih an inegral ime of 3-4 seconds. Then gradually lower he low superhea hreshold and increase he low superhea inegral ime, checking ha here is no reurn of liquid in any operaing condiions. Disconnec he saor from he valve and he cable and measure he resisance of he windings using an ordinary eser. The resisance of boh should be around 36 ohms. Oherwise replace he saor. Finally, check he elecrical connecions of he cable o he driver. Check if he superheaing is always low (<2 C) wih he valve posiion permanenly a 0 seps. If so, se he valve o manual conrol and close i compleely. If he superhea is always low, check he elecrical connecions and/or replace he valve. Decrease he value of he Valve opening a sar-up parameer on all he uiliies, making sure ha here are no repercussions on he conrol emperaure. Increase he value of he valve conrol delay afer defrosing parameer. Check ha he LowSH hreshold is greaer han he superhea value measured and ha he corresponding proecion is acivaed (inegral ime > 0sec). If necessary, decrease he value of he inegral ime. Se more reacive parameers o bring forward he closing of he valve: increase he proporional facor o 30, increase he inegral ime o 250 sec and increase he derivaive ime o 10 sec. Sagger he sar defros imes. If his is no possible, if he condiions in he previous wo poins are no presen, increase he superhea se poin and he LowSH hresholds by a leas 2 C on he showcases involved. Replace he valve wih a smaller equivalen. Check he calculaion in reference o he raio beween he raed cooling capaciy of he evaporaor and he capaciy of he valve; if necessary, lower he value. Check he conroller condenser seings, giving he parameers blander values (e.g. increase he proporional band or increase he inegral ime). Noe: he required sabiliy involves a variaion wihin +/- 0.5 bars. If his is no effecive or he seings canno be changed, adop elecronic valve conrol parameers for perurbed sysems (see paragraph 8.3) Check for he causes of he swings (e.g. low refrigeran charge) and resolve where possible. If no possible, adop elecronic valve conrol parameers for perurbed sysems (see paragraph 8.3). As a firs approach, decrease (by 30 o 50 %) he proporional facor. Subsequenly ry increasing he inegral ime by he same percenage. In any case, adop parameer seings recommended for sable sysems. Increase he superhea se poin and check ha he swings are reduced or disappear. Iniially se 13 C, hen gradually reduce he se poin, making sure he sysem does no sar swinging again and ha he uni emperaure reaches he conrol se poin. 49 EVD Evoluion TWIN EN - rel
