INSTRUCTIONS FOR INSTALLATION AND USE.
to reduce swings in steady-state temperature, increase the integral action time 1It; system stability is thus increased, although its
response speed is decreased;
to increase the speed of response to the variations in temperature, increase the derivative action time 1Dt; caution: a high value
makes the system sensitive to small variations and may be a source of instability.
CAUTION: during the auto-tuning procedure the temperature oscillates near the set point; it is therefore advisable to remove products to be
controlled within severe specifications
6. RECALIBRATION
If it is necessary to recalibrate the instrument, for example following replacement of a sensor, proceed as follows: have a precision
reference thermometer or a calibrator to hand; ensure that the offset OS1 and the simulation SIM are set to 00. Switch the controller off
then on again. During the internal self-test phase, press the keys
the recalibration function activated, select the value to be changed using
correction over the whole scale of measurement. SAd allows a calibration of the top part of the measurement scale with a proportional
correction between the calibration point and 0. After having selected the required parameter, press
+ or to make the read value coincide with the value measured by the reference instrument (ensure that the temperature is stable).
SET
Exit from calibration by pressing the key

7. SERIAL COMMUNICATION

LTR15 is provided with a serial port for connection with a PC or a programmer. In the first case it is important to assign a different value
to the ADR parameter for each linked unit (peripheral address); in the case of automatic programming, ADR should remain at 1.
