Term
Abbreviation Explanation
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.
Latch
An extra layer of protection that keeps the alarm action activated. When the alarm is
not active and acknowledged, it can be unlatched.
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. PPM 300 is part of ML 300.
Network time
protocol
NTP
Used to synchronise the time of a computer client or server to another server or
reference time source.
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.
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.
Out of service
A state that an alarm can be assigned to by an operator. Out of service alarms are
inactive alarms. Out of service alarms do not automatically return to service and
require operator action.
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 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.
