Vu les photos c'est pas petit peux tu donner les dimensions

quelqu'un sait il comment acheter 1 sonde de T° suplémentaire

[sorg]

Le modèle que j'ai recu fait 96mmx96mm en facade (pour environ 10cm de profondeur.
Le modèle proposé dans la commande groupée est plus compact: 48mmx48mm en facade.

Pour acheter une sonde de T° supplémentaire , il faut que je demande au vendeur. Normalement, c'est tout à fait possible.
Sinon tu cherches sur ebay, radiospares ou farnell des thermocouples ou sonde PT100...

Note 2:

This controller has improved algorithms to prevent over calibration during auto-tuning.

Atdu is the lower skew parameter during AT process.

P,I and d parameters control the accuracy and respond time of the temperature controller. Auto-tuning is recommended for user who do not familiar PID control theory. P, I and d values should only be adjusted by professionals.



Note 4

Proportional Band (P): When P increases, fluctuation of object being controlled decreases. When P decreases, fluctuation of object being controlled increases. When P value is too small, system may become non-converge.



Note 5

Integration time (I): its purpose is to reduce static error. When I decrease, respond speed is faster but system is less stable. When I increase, respond speed is slower, but system is more stable.



Note 6

Differentiation time (d): its purpose is to control in advance and compensate delay. Setting d-value too small or too large would decrease system stability, oscillation or even non-converge.



Note 7


Overshoot suppression coefficient. When overshoot exists, increase SouF. When undershoot exists, decrease SouF.







Note 8

Control Period (ot): When ot gets smaller, heating/cooling cycle is drived faster, system respond speed is faster. But when using contact control (Relays), contacts wear out faster.

When contact control (Relay) is used, normally set ot=5~15.

When non-contact control (SSR) is used, normally set ot=2.

Note 9

Digital Filtering (Filt): Filt=0, filter disabled; Filt=1, weak filtering effect; Filt=3, strongest filtering effect; Stronger the filtering, more stable the readout, but has more readout display delay.



c) To enter temperature and alarm parameter setting mode press (SET), then enter code “0001”, press (SET) again.

d) During Normal Operation mode, pressing (^) or (v), the display would show SV. Press (^) or (v) again increase or decrease SV by 1 degree.

a) Set AH1=AL1, relay is disabled.

b) Set AH1>AL1 (or AH2>AL2): Normally used for upper limit alarm trigger. See Figure 4.

c) Set AH1<AL1 (or AH2<AL2): Normally used for lower limit alarm trigger. See Figure 5.



5. Auto-Tuning

By simply press a single button the built-in artificial intelligent is activated to automatically calculate and set parameters (P,I,d,SouF,ot) that fit the condition to be controlled.

Figure 6.

a) How to Start and stop auto-tuning process:

i. To activate auto-tuning, press and hold (>) until “AT” indicator blinks, which indicates auto-tuning is in progress. When auto-tuning finish, “AT” indicator is off. Now newly calculated PID parameters are remembered and start to be used.

Ii To EXIT during auto-tuning process, press and hold (>) until “AT” indicator turns off. Then previous PID parameters values are resumed.



6. Connection Terminals (back view).

Polarity of power at terminal 1 and 2 do not matter





7. Device Application Example

User want to control temperature (T) of furnace, 0 ~ 1000 deg Celsius sensor range is required. Furnace is to be maintained at 800 deg C. Alarm1 will go off if T>850 deg C, and Alarm2 will go off if T<750 deg C. System power supply is AC110V. Installation opening is 45x45(mm). SSR will be used to control the heating element.

a) Choose VTC-620 with K-type thermocouple.

b) See figure for connection diagram.

c) Parameter setting:

(Inty)=K; (SV)=800 deg C;

(outy)=2; (AH1)=850 deg C;

(Atdu)=10; (AL1)=848 deg C;

(psd)=0; (AH2)=750 deg C;

(rd)=0; (AL2)=752 deg C;

(CorF)=0;

(auto-tuning is used to set PID parameters)

d) Power up the controller. Keep pressing (>) to activate auto-tuning. When “AT” stop blinking, new PID parameters are generated for the new system. The controller is in normal operation mode controlling the furnace temperature at 800 deg C.

Oups
en regardant la mise a jour de la commande je me suis trompé

Je voulais dire 1 Thermocouple et 2 SSR ( voir le post sur la config que je veux réaliser ) mais il me vient un doute dois je utiliser mes intéruptuers entre le SSR et la résitance ( dans ce cas il me faudra un seul SSR) ou entre le thermocouple et le SSr ( dans ce cas ils m'en faudra 2 )

une chose est sure il me faudra ( si c'est possible 3 sonde thermique)

donc suivant vos avis je confirmerais

[libertluc]

Décidément je suis un noob en élect

a la place de thermocouple dans mon poste précédent il faut lire régulateur et a la place de sonde thermique lire thermocouple

[libertluc]

Euhhh

sur ton shéma J1 et J2 on y branche quoi

déso d'être vraiment si nul en électr.

[libertluc]

Exemple de ce que je voudrais réaliser
