Pump controller operation
LAN/local control, automatic/manual operation
Figure 8-6; Pump Controller
With the Local/LAN switch (9), the user can put the pump either in LAN control or in Local control.
By default, the pumps should be in LAN control since this ensures the most efficient operation.
The controller maintains the pressure between programmable limits by running or stopping the
pumps.
When in LAN mode, these commands are relayed by the central controller. When in Local mode,
these commands are based on the pressure measured by the transducer located at the inlet of
the corresponding pump, see diagram: Plant description.
For maintenance reasons or in case of problems, it is advised to put the pump in Local control. By
default, a plant fault alarm is triggered when a pump is set to Local. To prevent this fault from
appearing during maintenance, isolate this pump in the central controller software (see Central
controller operation). After having switched to Local control (switch 9), stop the pump by pushing
the Stop button (11) and proceed by switching off the isolating switch (10).
To reinstate a pump, re-integrate it in the software, turn the isolating switch to On and put the
Local/LAN switch to LAN.
In LAN control, the pump is in automatic operation by default. In Local control, operation depends
whether the On or Off button is pressed on the controller (11 or 12). When the On button is
