Term Abbreviation Explanation
Magnetic pickup MPU
Measures the genset speed (that is, RPM). This sensor is normally located at the genset
flywheel.
Module
A standardised, replaceable printed circuit board that is mounted in the rack. For
example, PSM3.1 is a hardware module that supplies power to the rest of the rack.
Name [ ]
Square brackets show that the name inside the square bracket must be adapted
according to the controller type. For example, for a GENSET controller, [Source] is
"Generator".
National Electrical
Code
NEC
A standard for the safe installation of electrical wiring and equipment in the United
States.
Neutral N The neutral line in a three-phase electrical system.
Network ring
An Ethernet connection topology where the controllers are connected in a line, and the
last controller is connected back to the first.
Network chain An Ethernet connection topology where the controllers are connected in a line.
Non-essential load NEL
A load that is not critical to the system. These may be disconnected by the controller in
the event of over-load, over-current, or busbar under-current.
NPN A type of transistor.
Number #
Hash represents a number. The description is the same for each item in the range. For
example, "Controller ID #" represents any of the possible controller IDs.
Parameter
A value, or set point, used to determine the controller's operation. Parameters include
nominal values, the configuration options for the configurable inputs and outputs, and
alarm settings.
Phase L1 L1
The power line for one phase of a three-phase electrical system. Corresponds to R in
Germany, Red in the UK and Pacific, Red in New Zealand, Black in the USA, and U on
electrical machine terminals. The above colour codes are for guidance only. If uncertain
perform a phase measurement.
Phase L2 L2
The power line for one phase of a three-phase electrical system. Corresponds to S in
Germany, Yellow in the UK and Pacific, White in New Zealand, Red in the USA, and V
on electrical machine terminals. The above colour codes are for guidance only. If
uncertain perform a phase measurement.
Phase L3 L3
The power line for one phase of a three-phase electrical system. Corresponds to T in
Germany, Blue in the UK and Pacific, Blue in New Zealand, Blue in the USA, and W on
electrical machine terminals. The above colour codes are for guidance only. If uncertain
perform a phase measurement.
Power P The 3-phase active power, measured in kW.
Power in Control Utility
Software
PICUS The DEIF utility software, used to design, configure, troubleshoot and monitor a system.
Power management
system
PMS
The controllers share information and work together to ensure enough power to supply
the load.
Power supply module
3.1
PSM3.1
A replaceable PCB that powers the controller. This module includes three relay outputs
for status signals. Used in the DEIF controller.
Printed circuit board PCB Supports and electrically connects components.
Processor and
communication
module 3.1
PCM3.1
A replaceable PCB, which contains the controller processor, as well as the CAN bus
connections and Ethernet communication connections. Used in the DEIF controller.
Programmable logic
controller
PLC A digital computer used for the automation of electromechanical processes.
Protection and Power
Management
PPM
A versatile controller consisting of several modules and display unit designed for marine
use.
