Term
Abbreviation Explanation
Inhibit
A pre-defined condition that inhibits the alarm action. For example, for the inhibit
ACM wire break, if the controller detects a wire break on the voltage
measurements, the voltage unbalance alarm is prevented from occurring. Inhibited
alarms are not shown in the alarm display.
Internet Protocol
version 4
IPv4
A protocol for communication across networks. IPv4 currently routes the most
traffic on the Internet, but will gradually be replaced by IPv6.
Internet Protocol
version 6
IPv6
A protocol for communication across networks. Among other things, IPv6 has a
much larger address space than IPv4.
Light emitting diode
LED
Used to show the controller and equipment status and alarms.
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.
Multi-line 300
ML 300
A DEIF product platform. GPU 300 is part of ML 300.
Nominal setting
nom or NOM
Defines the expected voltage and frequency for the system, along with each power
source's maximum load and current. Many of the controller's alarms are based on
percentages of the nominal settings.
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.
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. The same set of parameters can be uploaded to
several controllers.
Personal computer
PC
Used to run the PICUS software. For example, a laptop computer.
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 factor
PF
The 3-phase power factor.
Power in Control
Utility Software
PICUS
The DEIF utility software, used to design, configure, troubleshoot and monitor a
system.
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.
Rack
An aluminium box with a rack system that houses the hardware modules. Each
controller consists of a rack and a number of hardware modules.
