PID Manual Tuning
The HS-7000 Series allows manual tuning of the the PID control parameters through the PID
Submenu.
HOW TO SET THE PID PARAMETERS MANUALLY
- Enter the PID Submenu pressing until [0000] [PASS] are displayed.
- Introduce the password correspondent to level 2.
- Press , the display will show [Auto] [Pid 1 ]
- Select the required Loop pressing until [Auto]
[Pid 2 ] or [Auto] [Pid 3 ] are displayed
- Press or until [MAn ] [Pid x] are displayed, where “x” is the number of the Control Loop.
- The message [MAn ] will flicker indicating that we are in the Manual Tuning function .
- To enter in Manual Tuning press .
- Select using one of the control parameters
[bP i] proprtional band of reverse PID
[ti i] integral time of reverse PID
[td i] derivative time of reverse PID
[bP d]
proprtional band of direct PID
[ti d]
integral time of direct PID
[td d]
derivative time of direct PID
[PulS]
Autotuning Pulse value
[CY 1]
time cycle of reverse control output by time modulation (relay)
[CY 2]
time cycle of direct control output by time modulation (relay)
The upper display indicates the actual value [xxxx] of each parameter.
- Press to modify. And then press or to introduce the new value.
- Press to save and select another parameter by pressing
- To exit press several times, until NORMAL DISPLAY.
