Self-Optimization - promesstec UREG 200 User Manual

Regulation with BPLS
With active BPLS, the control is quickly restored after a voltage failure with the
average of MV1 and the process deviation is smaller.
However, BPLS is not intended for long-term operation, fix the
error as soon as possible!

6.17 Self-optimization

The self-tuning works with an innovative algorithm
and offers an alterative to the setting of the
UREG200. To activate, set the parameter SELF =
YES. When self-tuning is enabled, the controller op-
timizes the PID values independently, based on the
comparison between current and previous control
cycles. When the UREG200 has found the optimum
control parameters, these are stored under PB1,
TI1, TD1 or PB2, TI2 and TD2 (depending on the
event input). After self-tuning is completed, the
SELF parameter is set to NONE to deactivate self-
tuning.
Self-tuning changes values more slowly than "Automatic setting" and causes less
process fluctuation. Usually, the self-tuning works successfully and does not require
any subsequent "automatic adjustment".
Exceptions: Self-tuning is disabled under the following conditions:
1. SELF = NONE
2. the ON-OFF control of the controller is active (PB = 0)
3. the controller is reset manually (TI = 0)
4. the controller has detected a control loop interruption
5. the controller is in error mode
6. the controller is in manual mode
7. the controller is in sleep mode
8. the controller is calibrated
