Description
The ProcessDefender’s installation simply requires the Power Transducer to be
mounted on a 35mm DIN rail, close to the motor starter. The clamp-on CT is to be
installed onto the L1 phase going to the motor, and the HMI is to be mounted in the
door of the motor control panel. Interconnecting wiring is clearly shown within this
installation Instruction Sheet.
Common applications for the ProcessDefender include:
•
Mag Drive Pumps
•
Screw (positive displacement) Pumps
•
Progressive Cavity Pumps
•
Conveyors
•
Mixers
•
Scrapers
•
Crushers
•
Circular and Linear Clarifiers
•
Belt-driven Fans

4.1 Important Notes
a.
ProcessDefender, PD100 has one model that is suitable for all motor
supply voltages, ranging from single-phase 100-240 VAC to three-phase
200-480 VAC.
b.
It is essential that the Current Transducer complies with the table below:
Motor Full Load
Amps / Rated
Motor Current

Notes:
1.
Please note that the max cable length (84 inches/2.13m) of the ProcessDefender CT cannot
be extended.
2.
A ‘pass’ through the Current Transformer equates to the number of times that the L1 wire
passes through the Core of the CT.
3.
The CT should only measure current going to the motor, i.e., care should be taken to ensure
that no other device is taking power from the wire going through the CT.
