Self setting operation steps of FP93 temperature control meter

Release date: July 29, 2014 reading times: 2877

Whether the temperature control table of industrial furnace is stable depends on whether the P, I and D parameters of the instrument are set reasonably.So, what about setting reasonable P, I, D parameters?When the setting control or program control is in operation state and the instrument is in the "basic window", press the cycle key to the [0-7] window, i.e. the self-tuning start / stop window. Use the "△" key to select the self-tuning as on and press the "ent" key to confirm. At this time, the "at" indicator on the instrument panel flashes and the self-tuning starts (the instrument must be in the platform section or "HLD" state before the self-tuning starts)After the self-tuning start, the instrument is in the position type working state, i.e. full on and full off state, generating two or three disturbances to the system. According to the magnitude of overshoot oscillation and the recovery period, the PID parameters of the system are calculated automatically.After the completion of self-tuning, the "at" light only lights up and does not flash. The P, I and D values of the current PID number of the instrument are automatically modified. The system returns to normal control, and then it is re adjusted to the [0-7] window. Select the self-tuning as "off" with "▽" key, and the self-tuning operation is completed.
