Explanation
Engine interface
module 3.1
EIM3.1
A replaceable PCB, with its own power supply. This module includes 4 relay outputs, 4
digital inputs, an MPU and W input, and 3 analogue inputs.
European Norm
EN
Standards issued by the European Committee for Standardisation (also known as
Comité Européen de Normalisation).
Firmware
Software that is installed in the controller. This software enables the controller to:
process inputs and outputs, display operating data, keep track of the equipment status,
and so on.
Generator breaker
GB
The breaker between a generator (for example, a genset) and the busbar. The GENSET
and EMERGENCY genset controllers can control a generator breaker.
Generator tacho
(measurement/output)
W
A generator tacho measurement. This can be used as a backup measurement for
generator speed.
GENSET controller
Controls and protects a genset. This includes control of the generator breaker. The
Power Management System can automatically start and stop gensets to ensure that the
required power is available.
Governor
GOV
Regulates the engine speed.
Governor and AVR
module 3.1
GAM3.1
A replaceable PCB, which includes load sharing capability. This module also includes 4
relay outputs, 2 analogue current or voltage outputs, a pulse width modulation output,
and 2 analogue current or voltage inputs.
Governor and AVR
module 3.2
GAM3.2
A replaceable PCB with its own power supply, two analogue outputs, a pulse width
modulation output, five digital inputs, a status relay output, and four relay outputs.
Ground
A connection between the equipment and earth. For marine applications, a ground is a
connection to the ship's frame.
GOST
Regional standards maintained by the Euro-Asian Council for Standardization,
Metrology and Certification.
Heavy consumer
HC
When a request is made, the power management system reserves and manages the
power required by the heavy consumer(s).
High speed digital
input
HSDI
MPU/W/NPN/PNP sensor digital input.
Horn output
The controller's digital output(s) that can be connected to a horn, a siren, lights, or other
equipment. This alerts the operator that one or more alarms are activated.
Hysteresis
An offset added to prevent rapid switching when a value is near the control point.
Ingress Protection
Rating, or International
Protection Rating
IP
The degree of protection against solids and water provided by mechanical casings and
electrical enclosures.
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.
Input output module
3.1
IOM3.1
A replaceable PCB, with 4 relay outputs, and 10 digital inputs.
Input output module
3.4
IOM3.4
A replaceable PCB, with 12 transistor outputs, and 16 digital inputs.
