MultiSmart Installation & Operation Manual

10.4 Pump Control Module

10.4.1 Pump Modes
Three pump modes exist for each pump controlled by the MultiSmart Pump Station Manager. They are
Manual, Off and Auto.
If Manual (Hand) mode is selected, the pump turns on unless the pump is faulted or unavailable. It returns
to Automatic mode when the deactivation setpoint is reached.
In Off mode, the pump does not start unless put into Manual or Automatic modes, even when the activation
setpoint is reached.
In Automatic mode, the advanced pump control module takes over the duties of starting and stopping the
pumps.
NOTE: The Off mode can be disabled (skipped), if desired, from the advanced settings menu. As a
safety measure, when this feature is turned off while the pump is already in Off mode, it will remain in
that state until the mode is change.
10.4.2 Fill / Empty & Pump Setpoints, Alarm Setpoints, Delays
Emptying or filling a well is supported along with multiple wells, either independent or balanced (however all
wells must be of the same type - empty or fill). Each mode has a default set of activation/deactivation points
for pumps and alarms. Four level alarms are supported for each well (where more than one well exists), with
the ability to disable/enable any alarm. Each level alarm has an activation and deactivation point. Activation
and deactivation delays are supported for each pump, as well as inter-pump delays. (See Section 12 for
more information).
10.4.3 Pumps & Groups
A single MultiSmart unit can support up to 6 pumps (depending on the configuration), which can be assigned
to more than one well if required. Multiple groups of pumps are supported. Typical applications for groups
are jockey pumps and flood pumps. Within a group, pumps can alternate or be in fixed sequence, and
maximum pumps running can be set. Groups of pumps can be alternated or in fixed sequence, and a
maximum number of groups running can also be set.
Some configuration parameters for pumps relate to whether they are the lead (duty) pump or the lag
(standby) pump. This capability is supported in the pump control module – parameters can relate to the
pump position in the alternation sequence rather than the physical pump, e.g. activation and deactivation
delays. See Section 13 for more information.
10.4.4 I/O, Faults & Level Devices
Inputs and Outputs (I/O), Faults and Level Devices are closely related. They all work together to provide the
functionality required to run a pump station.
•
I/O
General purpose I/O can be used to interface to a wide range of devices. Digital outputs are used
(via contactors or soft starters) to start and stop pumps, and to switch external hardware such as
solenoids, mixers or beacons. Some digital inputs have extra capabilities for interfacing to devices
such as Flygt CLS sensors.
•
Faults
Faults can be assigned to both digital and analog I/O. Inputs are used to detect faults within the
pump station, such as pump related faults.
•
Level Sensors
The pump control module supports multiple level sensors, including 4-20mA analog sensors (e.g.
pressure transducer, ultrasonic), MultiTrode conductive probe and ball floats. Support for
redundant level sensing is built-in.
See Section 14 for more information.
