Hyundai ACONIS-PMS Generator Display Panel
HYUNDAI
Refurbished
The Hyundai Heavy Industries ACONIS-PMS, also widely known as the ACONIS-2000 Power Management System, is a marine generator-control and electrical power-management platform designed for automatic operation of a vessel’s diesel-generator plant.
The photographed SM MARINE SERVICE™ unit is the operator/display panel for a three-generator configuration, with dedicated sections for:
DG1
DG2
DG3
together with central monitoring of:
Bus Bar Voltage
Bus Bar Frequency
Blackout Condition
Total Used Power
Available Power
The ACONIS-2000 manual describes the PMS as a system for full automation of the power plant, combining generator control, power management, generator protection and engine-safety functions.
The ACONIS-2000 PMS supervises the vessel’s generator plant and automatically decides when generators should:
The system can operate in both Manual and Automatic modes.
The manual states that each generator is equipped with its own independent and autonomous PMS section, providing a modular design intended to improve reliability and availability.
The photographed unit should also be optimized under the keyword:
Generator Display Panel – GDP
because that is the terminology used in the ACONIS-2000 manual.
The GDP is the front-mounted operator interface installed in the generator section of the main switchboard.
The ACONIS documentation describes it as the panel used to show:
Power
Current
Voltage
Frequency
together with generator sequence, alarm and status information.
The photographed panel has separate status sections for:
DG1
DG2
DG3
Each generator section provides generator status and failure indications.
Visible GEN-STATUS indications include:
STOPPED
RUNNING
STARTING
STOPPING
READY
BLOCK
Visible GEN.FAIL indications include:
START FAIL
SYNC FAIL
SHUT DOWN
ACB ABNOR. TRIP
ACB NON-CLOSE
These are highly relevant terms because engineers often search the exact alarm wording shown on the PMS panel.
The panel contains a dedicated display labelled:
BUS BAR VOLTAGE
The PMS continuously monitors bus voltage for generator synchronization and protection.
The ACONIS manual also documents:
Bus Bar Voltage Low
Bus Bar Voltage High
alarm functions, with configured limits and time delays.
The second central meter is labelled:
BUS BAR FREQUENCY
Frequency is essential for:
synchronizing
load sharing
generator protection
blackout/bus abnormal detection
The manual includes both low-frequency and high-frequency alarms as part of normal PMS protection.
The ACONIS PMS performs automatic synchronizing before a standby generator is connected to the live bus.
The system checks the deviation between the incoming generator and busbar conditions before allowing the generator breaker to close.
The ACONIS manual includes dedicated synchronization parameters such as:
Synchronize Time
Delta Frequency
Delta Voltage
CB Make Time
which are configured according to the vessel installation.
After multiple generators are connected in parallel, the ACONIS system performs automatic load sharing.
This is one of the strongest commercial keywords for this product because many engineers search for:
Hyundai Load Sharing Controller
rather than the complete ACONIS-PMS name.
The operator panel visibly provides:
LOAD SHARING – MANU / AUTO
selection.
The PMS adjusts generator loading through governor-control outputs to maintain appropriate load distribution.
Each generator section includes visible output indications:
GOV. RAISE
GOV. LOWER
These signals are used by the PMS to adjust the generator governor during synchronization, frequency regulation and load-sharing operation.
If a generator fails to synchronize or share load correctly, the governor raise/lower command chain should be checked before replacing the entire PMS.
The panel includes:
LOAD DEPENDENT START – MANU / AUTO
The ACONIS manual states that when vessel load remains above a preset value for a configured period, the PMS can send a start request to the first standby generator.
This allows additional generating capacity to be brought online automatically as electrical demand increases.
The panel also includes:
LOAD DEPENDENT STOP – MANU / AUTO
When total ship load decreases and sufficient reserve power remains available, the PMS can unload and stop an unnecessary generator according to configured parameters.
This improves generator operating efficiency and reduces unnecessary fuel consumption and running hours.
The photographed PMS panel provides a:
TOTAL USED POWER – kW
display.
This gives the operator a direct indication of the electrical power currently being consumed from the running generator plant.
The panel also shows:
AVAILABLE POWER – kW
This is an important PMS calculation because it tells the system and operator how much additional load the active generators can accept.
Available power is used in generator-start logic and heavy-consumer interlocking.
The ACONIS manual includes a Heavy Consumer Automatic Start function.
Large shipboard electrical loads may require confirmation that sufficient generator capacity exists before they are allowed to start.
The PMS can check available power and the number of parallel-running generators before granting a heavy-consumer start request.
The photographed control-mode area includes:
HEAVY LOAD
LIGHT LOAD
indications.
These are important for automatic generator-management decisions.
High load can generate a standby-generator start request, while prolonged low load can support automatic unloading and stopping of an unnecessary generator.
The panel has a prominent red:
BLACK OUT
indicator.
Blackout recovery is one of the most important functions of the ACONIS-PMS.
The manual defines blackout as a condition where no busbar voltage or frequency is measured and all generator breakers are open.
When blackout is detected, the PMS can:
start the first standby generator
bring it to running condition
issue the breaker-close command
restore the electrical bus
according to the configured sequence.
The system also performs bus abnormal recovery.
Abnormal bus voltage or frequency can trigger corrective generator operation.
The manual notes that bus-abnormal recovery may still be controlled automatically even when the running generator itself is selected in manual mode.
Each generator section has a visible:
STAND BY
indicator.
The ACONIS system allows generators to be assigned standby priority.
The manual describes:
1st Standby
2nd Standby
status, giving the PMS an ordered sequence for automatic generator starting.
Each generator section shows:
ACB ON
at the top.
Within the OUTPUT section the panel also has:
ACB OPEN
and synchronizing-related controls.
The ACONIS PMS provides automatic opening and closing commands for the generator Air Circuit Breaker according to operating conditions and permissives.
The PMS includes Reverse Power Trip protection.
The manual states that reverse power trip occurs when measured reverse power exceeds a configured value for the configured delay period.
This helps protect a generator that begins motoring rather than supplying electrical power.
ACONIS also includes generator current protection.
The user manual describes:
Over Current Trip
and short-circuit-related protection according to configured thresholds and delays.
The PMS continuously supervises busbar voltage.
The manual provides configured protection functions for:
Low Voltage
High Voltage
Low-Low Voltage
High-High Voltage
depending on system configuration.
Frequency protection includes:
Low Frequency
High Frequency
Low-Low Frequency
High-High Frequency
with configured alarm/trip delays.
The ACONIS system supports:
Preferential Trip 1
Preferential Trip 2
When generator capacity becomes insufficient or abnormal conditions occur, selected non-essential consumers can be disconnected to protect the main electrical system.
The manual explicitly includes two preferential-trip outputs.
The photographed unit includes a central CONTROL MODE section.
Visible options include:
MANUAL CONTROL
and
AUTO CONTROL
along with MANU/AUTO selection for:
Synchronizing
Load Sharing
Load Dependent Start
Load Dependent Stop
This makes the system flexible for both normal automatic operation and maintenance/testing.
The GDP shown in the photograph is only one part of the ACONIS architecture.
The second major component is the:
GCE – Generator Control Equipment
The manual states that each generator has a GCE mounted inside the generator panel.
Field signals from:
busbar
generator
engine
breaker
are connected directly to the GCE.
Therefore a vessel reporting an “ACONIS PMS fault” may require a GCE or internal PCB rather than a replacement front panel.
The manual references a:
GCMI-CPU
within the Generator Control Equipment.
This is an important search term because many service engineers search for individual cards instead of the full ACONIS unit.
Keywords such as:
ACONIS GCMI CPU
Hyundai PMS CPU board
ACONIS-2000 CPU module
should therefore be included in the page.
The GCEs are connected to one another through a redundant field bus based on ARC-Net.
The ACONIS manual states that each generator controller communicates with the others through this redundant network.
This distributed design improves reliability, but network problems can also produce synchronization or system-status issues.
The ACONIS-2000 user manual gives system specifications including:
| Parameter | ACONIS-2000 PMS |
|---|---|
| Control Supply | 24VDC |
| Processor | Intel XScale PXA-255 |
| CPU Clock | 200 MHz |
| SDRAM | 32 MB |
| Read/Write Memory | 32 MB |
| Non-volatile Memory | 4 kB |
| Watchdog | Yes |
| Power-Fail Logic | Yes |
| Operating Temperature | 0–70°C |
| GDP Protection Degree | IP52 |
| Network | Redundant ARC-Net field bus |
These specifications refer to the documented ACONIS-2000 system generation and may vary by project/revision.
The referenced ACONIS manual describes a three-generator application but states that the PMS can support up to five generator sets in the documented architecture.
Therefore related search terms such as:
3 DG ACONIS PMS
4 DG ACONIS PMS
5 Generator ACONIS PMS
are useful without claiming every installation has the same panel arrangement.
Hyundai switchboard drawings list:
POWER MANAGEMENT SYSTEM – ACONIS-2000 PMS
as dedicated equipment in diesel-generator panels and show separate PMS power, analogue input, binary input, binary output and CPU communication drawings.
This confirms that ACONIS-2000 is integrated directly into the vessel's main-switchboard architecture.
