MultiSmart Installation & Operation Manual
A Pump Efficiency Warning is also available which displays a warning if efficiency (in say L/kWh) falls below
a threshold.

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 an SD card or USB and
then transferred to a computer and viewed via Excel, Access, or any other reporting/database tool. The
datalogger stores approximately 100,000 events and faults, but this can be significantly increased by logging
data to an SD card instead. 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 also 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.
10.10

Security

The MultiSmart can restrict access to the configuration menus and other screens. Each user is assigned a
PIN 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. An alternative method to log-in is via a digital input. A third
method requires a Security or Dallas (iButton) 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 and above. 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. It uses
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.
