BURKERT控制器787757技術(shu)參數：
Controller structure | P, I, PD, PI, PID | PID | Control loop feedback | |
Proportional band | 0 | to 9999 digits | 0 digits | Size of the proportional band |
|
|
|
| 0 means that the controller structure is out of action! |
Derivative time | 0 | to 9999 sec | 80 sec | Determines the differential component of the controller output signal |
Reset time | 0 | to 9999 sec | 350 sec | Determines the integral component of the controller output signal |
Cycle time | 0 | to 9999 sec | 20 sec | When using a switched output, the cycle time should be chosen so |
|
|
|
| that the energy fl ow to the process is quasi continuous, i.e. as con- |
|
|
|
| tinuous as is practicable without overloading the switching elements |
Contact spacing | 0 | to 999 sec | 0 digits | The spacing between the two controller contacts for double- |
|
|
|
| setpoint or modulating controllers, or proportional controllers |
|
|
|
| with an integrated actuator driver |
Switching differential | 0 | to 999 digits | 1 digits | Hysteresis for switching controllers with proportional band = 0 |
Actuator time | 5 | to 3000 sec | 60 sec | The actually utilized operating time of the regulator valve with |
|
|
|
| modulating controllers or proportional controllers with an integrated |
|
|
|
| actuator driver |
Working point | -100 | to +100% | 0% | The output level for P and PD controllers (if x = w then y = Y0) |
Output level limiting | 0 | to 100% | 100% | The maximum limit for the output level |
| -100 | to +100% | -100% | The minimum limit for the output level |
Minimum relay ON time | 0 | to 60 sec | 0 sec | Limits the frequency of switching for switched outputs |
