34 Application on industrial kilns

Controller ATR620 has a wide range of applications on industrial

kilns, environmental chambers, furnaces, dryers…

Certainly some of the most common application fields are

electrical kilns for ceramics, glass, metalworking. Below some

examples with a short list of main configuration parameters.

35 Kiln with single thermocouple and SSR control

This is probably the most typical application of controller ATR620,

using only main capabilities of the unit and still keeping high user-

friendliness..

On electrical kilns ATR620 performs control loop for the

programmed cycle reading thermocouple value and controlling

SSR. In case that alarm conditions, as overshooting of max.

temperature, are noticed relay A1 is activated to open the circuit

with safety contactor, along with acoustic signal of internal buzzer

and a flashing signal on display. Should the kiln door accidentally

open, this is also an alarm condition: cycle is stopped and a

corresponding message is visualized on display.

Programming of main parameters:

P-01

0009 15 cycles available, 20 steps each

Special functions are desabled

P-02

1000 Select thermocouple K (ex.:1100 for TC typeS)

P-05

5000 Select SSR control output for process 1

P-06

0 Minimum temperature (lower limit scale) 0°C

P-07

1350 Max. temperature (upper limit scale) 1350°C

P-12

1101 Max. temperature alarm with cycle block

P-15

1300 Alarm setpoint: if kiln temperature is over 1300°C,

the cycle is stopped.

P-17
