Controller options
Controller options should be set for fast response. Below typical (fast response) settings for a pump controlled by a mini CORI-
FLOW instrument.
Valve powers, with the learn open function the instrument will
determine what the opening voltage of the used actuator is
(e.g. a valve or a pump).
After this value is known the opening response will be adapted to
decrease the dead time during setpoint steps from zero.
Setpoint slope. Normally = 0, except when PID-Td > 0.
PID-Kp: Typical = 10. Increase in range 10…100 to make controller
faster. Decrease to slow down.
PID-Ti: Typical = 0.1. Decrease in range 0.02..0.1 to make controller
faster. Increase from 0.1…2 to slow down.
PID-Td: Typical = 0. Increase a little (0…2 sec.) to differentiate dead
volume if necessary.
Special adjustment for PID-Kp at certain situations for extra speeding
up or slowing down.
