These parameters should only be changed in small increments, and
the effects on the system should be monitored continuously. Param-
eter values should only be tuned by someone with training in control
engineering.
Controller Factory setting Setting range
term
P 0.5
I 0.5 s
D 0 s
(= deactivated)
The direction of action of the controller is determined by the sign of
the P term.
Positive PID control (default):
If the sign of the P term is positive and the process value drops below
the setpoint, the control will increase the pump speed until the set-
point has been reached.
Negative PID control:
If the sign of the P term is negative and the process value drops below
the setpoint, the control will decrease the pump speed until the set-
point has been reached.
NOTE
Check the controller's direction of action if PID control is being used,
but the pump is only running at minimum or maximum speed without
responding to changes in the parameter values.
Maintenance and repairs may only be carried out by qualified
experts!
It is recommended to have the pump serviced and checked by Salm-
sonCustomer Service.
