Installation and operating instructions SIE, DIE, PBE
The I (or integral) term of the controller provides integral control
based on the system deviation. A constant deviation results in a linear
increase at the controller output. Hence a continuous system devia-
tion is avoided.
The D (or derivative) term responds directly to the rate of change of
the system deviation. This affects the rate at which the system
responds. In the factory settings, the D term is set to zero, since this
is an appropriate setting for a number of applications.
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
technology.

Table 9: PID parameter
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.
Have maintenance and repair work carried out by qualified
personnel only!
It is recommended to have the pump serviced and checked by Salm-
son customer service.
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock when working on
electrical equipment.
• Work on electrical equipment may only be done by electricians
approved by the local electricity supplier.
• Before working on electrical equipment, switch it off and secure it
against being switched on again.
• Any damage to the connection cable of the pump should always be
rectified by a qualified electrician only.
