Explanation
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.
Oil pressure
OP
Operate time
The time that the controller takes to measure, calculate, and change the controller
output. For each alarm, the reaction time is based on the minimum setting for the time
delay.
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.
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.
Phasor
A complex plane representation (that is, a magnitude and direction) of a sinusoidal
wave.
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 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.
Power take home
PTH
The shaft generator is used as a motor to drive the ship's propellor.
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.
Proportional integral
derivative
PID
A feedback controller.
Protection and Power
Management
PPM
A versatile controller consisting of several modules and display unit designed for marine
use.
Pt100, Pt1000
Platinum temperature sensors
