1 92.507/1 EYR 203, 207: novflex universl controller novflex, universl controller of the EY3600 fmily, is used in HVAC control systems. The EYR 203 hs totl of 18 inputs nd 10 outputs, while the EYR 207 hs 20 inputs nd 10 outputs. The cycle time even fst control tsks to e performed. With the novnet supplementry module, the 203 nd the 207 cn e networked nd hve communiction cpility. Any progrmming (prmeterising) is done with PC using EY3600 CASE softwre s per IEC (FBD Editor). With the novnet supplementry module (ccessory ), novflex hs ll ssemlies nd interfces needed for opertion, for connecting the plnt devices nd for communiction with other sttions, with the touch-pnel nd with the mngement level. sing the Pt to Pt supplementry module (ccessory 37448), communiction with the EYT 250 touchpnel is possile even without novnet.

2 92.507/2 EYR 203/207 Engineering notes The novflex universl controller cn e fitted in cinet y mens of top-ht ril (EN 50022). The sttion requires power supply of 24 V~. The erthing terminl is connected to the erth connection (PE) nd the housing. The plnt devices re connected vi screw terminls. The following conditions must e oserved:- Cross-section of wire: min. 0.8 mm 2 (AWG 18), mx. 2.5 mm 2 (AWG 13), oserving the stndrds novnet: with twisted cle, mx. expnsion 200 nf/300 Ω, loding 0.6 nf Digitl inputs: potentil-free contcts, opto-coupler, trnsistors (open collector) open: > 3.5 V, closed: < 1 V Digitl outputs: < 250 V~ / 2(2) A t the rely contcts L/CSA: < 30 V~ /2(2)A 24 V~ / 1A t the trics Anlogue inputs: d.c.

The sensors re connected using two-wire technology, with the wires llowed to e up to 55 m (180 ft) long if 0.8 mm 2 (AWG 18), or 170 m (558 ft) long if 1.5 mm 2 (AWG 15). The mesuring voltge is pulsed so tht the sensor does not het up. While the inputs were designed for Ni1000 sensors, they cn lso e used for Pt1000. The type of mesurement is chosen vi the softwre. The lineristion for Pt1000 gurntees negligile devition in the rnge 50 to +100 C ( F). For the full mesuring rnge of the Pt1000, the following tle pplies:- Temperture Asolute difference 100 C ( 148 F) 0.05 C ( 0.09 F) 50 C to +100 C ( F) < ± 0.02 C (± 0.04 F) +150 C (302 F) C (+0.09 F) 200 C (392 F) C (+0.2 F) 300 C (572 F) C (+0.52 F) 400 C (752 F) C (+0.18 F) 500 C (932 F) 0.31 C ( 0.56 F) Importnt note The novflex hs 128 MFAs nd cn store entries in the HDB.

Mesurement 0 (2)...10 V is selected vi the softwre. The mximum permissile voltge (without incurring dmge) is < ± 50 V. The rnge shown, however, is limited to 10 V. The internl resistnce R i of the input is > 20 kω in this cse.

So s not to overlod the reference outputs, the lowest potentiometer vlue should not e less thn 1 kω. The upper vlue of 2 kω is prescried in order to gurntee tht mesurements re stle nd free of interference. Current mesurement sing n externl resistor of 50 Ω (EYR 203) nd 100 Ω (EYR 207), it is possile to mesure current.

The inputs to e monitored re connected etween the input terminls nd erth. The sttion pplies voltge of pprox. 13 V t the terminl. When the contcts re open, it denotes Bit = 0. When the contcts re closed (denoting Bit = 1), the voltge is nought nd current of pprox. 0.4 ma flows. Brief chnges of t lest 32 ms re uffered etween the sttion's polling nd then processed t the next cycle.

The output voltge is mesured etween the relevnt output terminl nd n erth terminl. Outputs cn provide ma. The outputs re protected ginst sttic dischrges, ut not ginst direct or lternting current. These cn dmge the protective diode nd the output driver. Therefore, the plnt device (e.g. vlve drive) should lwys e connected first in the system. Then check should e mde t the sttion to ensure tht neither of the two lines hs ny potentil t ll (0 V) with respect to erth nd to ech other. If this is the cse, the erth led should e connected first, then the signl led to its terminl t the sttion. The novflex hs fst operting progrm. It reds ll the inputs, processes the prmeterised modules, updtes the outputs nd, using the novnet supplementry module, effects the necessry communiction with other sttions or visulistion PCs. Any progrmming chnges to the novflex (control loops nd prmeters) re effected vi the novnet utomtion net. A rel-time clock for the time progrmmes is integrted in the novflex. A lithium ttery ensures tht the user dt (FBD dt), time progrmmes nd historicl dt (HDB) re retined in the SRAM in the event of power filure. The rel-time clock lso runs off this lithium ttery. The ttery mkes it possile to retin the dt nd run the rel-time clock for t lest 10 yers without power pplied. The dt cn e sved permnently using SER-PROM. Ech novflex with novnet supplementry module requires n ddress ( ), which is set vi coding switches. p to 128 novflex suscriers cn e connected to the novnet. The EYT 240 F001, EYT 250 F001 nd EYT 250 F002 control pnels re ville for the novflex. The EYT 240 is linked to the sttion vi n RJ-45 socket. It enles the opertor to use ll dt (with the exception of the HDB) of the novflex (i.e. to red out mesured vlues, lrms nd sttuses, to chnge setpoints nd to issue positioning commnds). The EYT 250 is linked to the sttion vi n RJ-11 socket (supplementry module Pt. to Pt., ccessory no ) or vi novnet. It enles ll dt to e used.

5 EYR 203/ /5 Putting into opertion When connecting the 24 V~ power supply, the technicl erth must e linked with the terminl screw provided. Work should lwys e crried out with the power supply switched off. Before eing incorported into novnet, every sttion must e given cler (unique) ddress. The ddress re is split up into rnges. For novflex, only the rnge from 0 to 127 cn e used. This novflex numer is inry coded using the lock of DIL switches of the novnet supplementry module. Off On Wert Off On Even Prity Numers re ville for novflex. The AS ddress cn e set using the lock of eight switches. The lst switch is used to set the prity, which should e set so tht the numer of switches t 'On', including prity, is even. Exmple: = 15 B09611 novflex must e removed from the power supply efore eing opened. ESD protective mesures must e tken efore crrying out ny work. Initilistion Initilistion is effected y shorting the Ini utton for pprox. ½ second. This cuses the sttion to lod the microprogrm from the SER-PROM nd to commence opertion under defined strting conditions. Both versions, EYR 203 nd EYR 207, hve green LED next to the connection terminls. When lit continuously, it indictes tht power is on. The novnet supplementry module hs yellow LED which indictes the telegrm trffic when sending on the novnet. If the sttion hs stopped or if fult hs een detected in the RAM, this is noted y the wtchdog, nd the sttion is then re-strted with the PROM dt. In this cse, no telegrms re sent for short period, so the yellow LED stops flshing. If this LED does not light up t ll, either the PROM is fulty or there is no PROM t ll, therefore, the sttion is no longer operle. In stnd-lone mode (without novnet), the 'Send' LED flshes quickly (pprox. 7 times per second), since n empty telegrm (dummy) is sent every cycle. When the sttion is put into opertion for the first time, or if it is mnully reset, the microprogrm nd the user dt re red in fresh. As soon s this hs een concluded, the yellow 'Send' LED flshes gin t the sme rte s the outgoing telegrms.
