Installation and operating instructions SIE, DIE, PBE
NOTE:
For further information about setting the control mode and the associ-
ated parameters, see chapter 8 "Operation" on page 91 and chapter 9.4
"Setting the control mode" on page 108.
NOTE:
A differential pressure sensor is needed for the control modes that are
being performed ( p-c and p-v) which sends the actual value to the
electronic module.
NOTE:
The pressure range of the differential pressure sensor must match the
pressure value in the electronic module (menu <4.1.1.0>).
Manual control mode:
The speed of the pump can be kept to a constant speed between n
and n (Fig. 12). "Manual control" mode deactivates all other con-
max
trol modes.
PID control:
If the aforementioned standard control modes cannot be used – e.g.
if other sensors are to be used or the distance between the sensors
Q
and the pump is very large – then the PID control (Proportional-Inte-
Q
gral-Differential control) is available.
By selecting a good combination of individual control portions, the
operator can ensure fast reacting, constant control without lasting
setpoint deviations.
The output signal of the selected sensor can take any intermediate
value. The respective actual value reached (sensor signal) will be
shown as a percent (100% = maximum measurement range of the
sensor) on the status page of the menu.
NOTE:
The displayed percent value only corresponds indirectly to the current
delivery head of the pump(s). It is possible, for example, that the maxi-
mum delivery head has already been reached at a sensor signal < 100%.
For further information about setting the control mode and the associ-
ated parameters, see chapter 8 "Operation" on page 91 and chapter
9.4 "Setting the control mode" on page 108.
