8.4.5 Individual pump control (2.1.4)
Individual pump control
Description
You can change the operating mode from automatic operation to
one of the manual operating modes.
Auto
The pumps are controlled by the PI controller, ensuring that the
system delivers the required performance.
Manual
The pump is not controlled by the PI controller, but set to one of the
following manual operating modes:
• Max.
- The pump runs at a set maximum speed. This operating
mode can only be selected for variable-speed pumps.
• Normal
- The pump runs at a set speed.
• Min.
- The pump runs at a set minimum speed. This operating
mode can only be selected for variable-speed pumps.
• Stop
- The pump has been forced to stop.
Pumps in manual operation are not part of the normal pump
cascade and speed control. The manual pumps are a 'disturbance'
of the normal operation of the system.
If one or more pumps are in manual operation, the system may not
be able to deliver the set performance.
There are two displays for the function. In the first display, select the
pump to be set, and in the next display, select the operating mode.
Setting range
All pumps can be selected.
Setting via the operating panel
