3. description
ProcessDefender is an accurate and reliable Motor Load (Power) Monitor, designed
to protect rotating equipment from expensive damage and downtime caused by
abnormal process overload and underload conditions.
ProcessDefender uses the motor as its own sensor, thereby eliminating the need
for external sensors such as temperature probes, pressure sensors, fl ow monitors or
vibration transducers, etc.
ProcessDefender ‘learns’ the normal process load and then, when instructed to do
so, automatically sets itself to protect against abnormal overload and/or underload
conditions.
A key feature of ProcessDefender is its ability to protect the Engineer and Operator
from Arc Flash. Programming and Alarm Reset is via the externally mounted HMI
or Modbus interface. Previous Motor Load Monitors have typically been installed
inside a motor control panel and where the user can be exposed to dangerous Arc
Flash conditions - a situation where a violent fl ashover of electrical current can occur
and where the user can experience serious injury or even death. ProcessDefender
eliminates these concerns.
ProcessDefender includes 3 fully programmable relays. The relays are designated as
follows:
•
Relay 1: Main Alarm - typically used to shut down the motor in the event
of an abnormal process load condition.
•
Relay 2: Pre-Alarm - an early warning of an impending main alarm.
•
Relay 3: General Alarm - used to signal an array of other monitored
parameters such as over / under voltage, phase symmetry (imbalance),
locked rotor, exceeded starts per hour limit.
The HMI can display % motor load, HP, kW, Line Voltage, measured Amps.
