Energy Monitoring And Motor Protection - MultiTrode MultiSmart Installation & Operation Manual

10.4.5 Profiles
The pump control module supports six (6) profiles. Each profile consists of pump activation/deactivation
setpoints, as well as four station optimization functions (Max Off Time, Max Run Time, Station Max Pumps to
Run & Well Clean Out). Profiles can be switched via any of the following methods: (See Section 15 for more
information).
•
User interface
•
SCADA
•
A timer (e.g. time of day)
•
Digital input (e.g. a switch on the panel) or any digital tag (e.g. an alarm condition)
•
Logic engine script or ISaGRAF program
10.4.6 Station Optimization Functions
Many desirable functions are pre-defined, with the user simply enabling/disabling or choosing parameters for
the functions. These functions include:
•
Pump Reversal (to avoid blockages)
•
Odor Reduction (via maximum off time)
•
Maximum Run Time
•
Station Maximum Pumps to Run (for electrical or hydraulic overload protection)
•
Minimize Fat Buildup (via random duty start)
•
Well Clean Out
•
Minimize Excessive Starts
•
High Inflow
•
Well Washer
•
Well Mixer
•
Blocked Pump Detection
•
Pump n Max Starts per Hour
See Section 16 for more information.
10.4.7 Watchdog
The pump control module includes a watchdog function which counts up while the pump control module is
functioning. This value is available as a tag in DNP3 and Modbus so that a SCADA system can monitor the
health of this module.

10.5 Energy Monitoring and Motor Protection

An optional Energy Monitoring Motor Protection module in conjunction with a Motor Protection card can be
supplied with the MultiSmart pump station manager. The module monitors currents and provides protection
from:
•
Over and Under Current
•
Over Current I
•
Current Phase Imbalance (or Phase Failure)
•
Current Phase Rotation
•
Ground (Earth) fault
This module also periodically tests the insulation resistance of the motor windings. Two user defined
thresholds can be entered one for a warning message and a second for a fault message, neither or both can
be configured to fault a pump if the IRT value falls below the thresholds.
