10.6 Supply Protection

The Pump Control I/O Board monitors the three phase supply through the "Mains Voltage Monitoring" inputs.
Single or 3 phase supplies can be monitored by the MultiSmart. The voltage is constantly measured and is
used to detect the following conditions:
Under & Over Voltage
•
Voltage Phase Imbalance (or Phase Failure)
•
Voltage Phase Rotation
•

10.7 Data Logger

The MultiSmart unit has a datalogger. The logged data can be downloaded onto a compact flash card and
then transferred to a computer and viewed via Excel, Access, or any other reporting/database tool. The
datalogger stores approximately 50,000 events and faults. Each event or fault is date/time stamped. See
Section 19 for more information.

10.8 Flow

The flow module is used to calculate inflow, pump flow rates and total station volume. This allows flow to be
derived without needing a flow meter. See Section 20 for more information.

10.9 Fault Module

The fault module handles pump and station faults. Many pre-defined faults exist, e.g., thermal overload,
contactor auxiliary and Flygt FLS. A fault only needs to be assigned to an I/O (within the configuration) to
begin to function. New faults can of course be defined. Any fault can be configured to lock out a pump, well
or station until a manual (or SCADA) reset is performed. A fault can also be configured to allow the pump to
become available when the fault clears, or after a deactivation delay.

Security

The MultiSmart can restrict access to the configuration menus. Each user is assigned a PIN number which
they enter before being allowed access. By enabling security, a user must log-in before making changes to
the configuration and before accumulators can be cleared. Pump information (such as Runtime Statistics)
can still be viewed without a PIN number. An alternative method to log-in is via a digital input. A third
method requires a Security or Dallas key which is placed on a reader. User access rights are managed by
an administrator. See Section 11 for more information.
10.11

PLC Extension (IEC 61131-3)

ISaGRAF, a control software environment which supports all of the internationally recognized IEC 61131
control languages and offering a combination of highly portable and robust control engine, is available in
MultiSmart. MultiSmart currently only supports ISaGRAF version 5. Earlier versions of ISaGRAF are not
supported. See Section 24 for more details.
10.12

Logic Engine

A simple, Boolean, logic engine has been built into the MultiSmart to allow basic customization of control
capabilities thereby extending existing functionality or allowing new functionality to be added.
mathematical expressions which are evaluated at regular intervals to determine if they are true or false. The
expressions are associated with a tag within the MultiSmart to create actions when an expression changes
state. See Section 25 for more information.
10.13

RTU

The MultiSmart can be supplied with an optional RTU. Supported communication protocols are Modbus and
DNP3 with security are available. The MultiSmart can also be shipped just as an RTU without any pump
controller functionality or user interface. See Section 21 for more information.
The diagram below illustrates the extensive communication capabilities of the MultiSmart, even though in
practice it is highly unlikely to use all of these in the same installation. MultiSmart can be interfaced with
most industry standard equipment and SCADA networks.
