PMC Type 5401 Lever Telegraph Systems transmit propulsion orders from the ship's wheelhouse to the engine control room or local at engine control station(s) as backup communication for emergency operation when primary remote control fails.

This traditional lever style telegraph allows bi-directional communication in the form of orders placed and acknowledged by moving the telegraph levers at the requesting and acknowledging stations.

Optional wrong direction audible and visual alarms, with adjustable time delay, are activated when the direction of propulsion is not the same as the acknowledged telegraph order.

System design allows for up to nine wheelhouse stations and six machinery space station for twin or single screw operation.  Twin screw systems can have one or more control stations split into separate units if required for situations such as local at engine installation.

The PMC Type 5401 Lever Telegraph Systems can be integrated with the propulsion control heads, allowing for electrical independence with shared mechanical connection.  On loss of propulsion control or transfer to a machinery space station, the bridge operator continues to use the same levers, but now telegraph orders are generated for emergency communication.

PMC Type 8180 dimmable LCD display is available as either a tachometer display or an engine communication gateway/display.

The tachometer display is suitable for either uni-directional or bi-directional rotating machinery, providing prominent display of ahead and astern direction indication.  The display provides isolated rpm signal inputs and meter outputs for driving remote analog displays.  Four programmable open collector input/outputs and one dry contact relay output are provided for external logic, interlocks or fault output.  A Modbus RTU slave communication port allows networking with other PMC or OEM applications.

The engine communication gateway/display indicates machinery operating parameters as available from serial communication sources (SAE J1939/J1587, NMEA) and provides the data on a Modbus RTU slave port for use by other PMC or OEM applications.

The PMC Type 8003 Integrated Machinery Alarm and Control Systems (IMACS) is a technically advanced Windows based graphical user interface for machinery alarm and control functions.  Seamlessly integrating with PMC’s Omni Chief distributed control and monitoring system hardware, the IMACS provides easy-to-use graphical displays for systems automation, safety systems, trending, health monitoring, power management, fire suppression, motor control and environmental control (HVAC).

The IMACS workstations and Omni Chief units, featuring layered redundancy with an optional dual high-speed network, function independently, without a centralized file server.  The IMACS can summarize and network all the data that is collected from electronic engine packages, fire alarm panels, power management systems, motor controls, environmental controls and other electronic control systems throughout the vessel.

Type 8010, Type 8012. and Type 8014 Navigation Light Control Panels for optically isolated supervision of navigation light fixtures, branch circuit wiring and power sources.  Suitable for controlling dual, single or twin single lamp fixtures, fed from dual independent power sources.

All three panels provide dimmable LED indicators for lamp on, lamp circuit failure, primary and secondary power available and power fail.  Audible alarms sound on failure; the panels include a silence pushbutton.  Type 8010 and Type 8012 include front replaceable fuses are used in the lamp control and power select modules.

The Type 8012 Navigation Light Control Panel provides for a higher lamp load capacity and automatic transfer features for both lamp control and input power.  On primary lamp failure, there is automatic transfer to secondary lamp for duplex fixtures.  Primary power source failure will result in automatic transfer to the secondary power source.

The Type 8014 Navigation Light Control is a compact, control, alarm, and monitoring system for single, twin single, or dual style LED navigation light fixtures.

The Type 8014 display unit contains all push buttons and audible/visual indicators required for monitoring and control functions. Illuminated push buttons are provided for individual lamp on-off control, group functions, primary and secondary power source selection, dimming control, and test/silence. Dimming control of all panel back lighting and indicators is provided for viewing in conditions ranging from direct sunlight to night operations. An internal horn is provided for audible indication of all faults.

The Type 8014 control unit is connected to the display unit by serial communication.  All navigation light fixture connections are made at the control unit. The internal control circuitry monitors the fixtures for failure or wire breakage. Fixture “running hour” monitoring can be enabled to provide notification of the calculated end of useful life of the LED array. On primary lamp failure, there is automatic transfer to secondary lamp for duplex fixtures. Input power is similarly monitored for availability and failure; transfer to secondary power will automatically occur on primary power failure. All fuses for power inputs and lamp outputs are front replaceable, without disassembly/opening of the control unit.

The Type 8014 NLP system can be configured to operate from 12 Vdc, 24 Vdc, 120 Vac, or 240 Vac power sources in and is available in 10 or 14 position sizes to suit vessel requirements. Multiple display units and control units can be interconnected to create larger fixture capacity.

Additional features of the Type 8014 include:

• Self-diagnostics and troubleshooting display for ease of maintenance.
• Serial output for connection to ship’s vessel monitoring system (Modbus RTU slave) for remote monitoring and control of the navigation light fixtures.
• Grouping of common task lights to activate together.
• Function keys to change multiple lamps or special lamp functions.
• Serial output for connection to ship’s VDR (NMEA 0183).
• Optional inputs/outputs can be provided to interface with remote mimic panels.

PMC Type 8110 tank level indication and alarms for up to eight tanks can be monitored simultaneously, displayed in user selectable units of measure.

Each tank level display consists of an engraved nameplate for tank identification, large six digit LED display for level status, bargraph for percent volume display, four alarm LEDs for high and low level alarms (Very High, High, Low, Very Low) and alarms for high flow rate (leak detection) and transducer fault.

Four relay outputs are available per panel for alarming purposes.  Outputs can be programmed for any one of the six alarm conditions available on any one tank, or can be programmed to follow alarm conditions on multiple tanks.  Each alarm point is provided with independent time delays for SLOW and FAST scan rates.

Four analog outputs are available per panel for display purposes.  Outputs can be programmed for any one of the eight tanks.

Two scanning rates are incorporated into the panel.  FAST scan is used when filling to ensure instantaneous readings, and SLOW scan is used while under way to cancel out the effects of fluids sloshing around in the tanks.  The SLOW scan rate is tuned to cancel out the natural roll frequency of the vessel.  Panels with out this feature will display erratic unusable readings during rough conditions.

With the TEST, SILENCE, and ACKNOWLEDGE push buttons the Tank Level Monitor is a fully operational alarm and monitoring panel for tanks.

PMC Type 8202 Pushbutton Telegraph Systems transmit propulsion orders from the ship's wheelhouse to the engine control room or local at engine control station(s) as backup communication for emergency operation when primary remote control fails.

This pushbutton style telegraph allows bi-directional communication in the form of orders placed and acknowledged by selecting the desired pushbutton orders at the requesting and acknowledging stations.

Optional wrong direction audible and visual alarms, with adjustable time delay, are activated when the direction of propulsion is not the same as the acknowledged telegraph order.

System design allows for up to nine wheelhouse stations and nine machinery space station for twin or single screw operation.  Twin screw systems can have one or more control stations split into separate units if required for situations such as local at engine installation.

PMC Type 8550-3200 Digital Propulsion Control for vessels equipped with controllable pitch propellers.

The PMC Type 8550-3200 MPC-CP is designed to accommodate a wide range of propulsion control requirements from the simple to the sophisticated. It is equally suited for single or multi engine installations as well as arrangements with power take off devices such as generators and fire pumps.

Advanced programming techniques for items such as remote control, speed/power curves, load sharing, load control, servo loop characteristics, alarms and operator messages ensure a high degree of flexibility and superior performance.

The MPC-CP automatic load control for controllable pitch propellers is fast yet completely stable. Dual dynamics are implemented in installations where the propeller is anticipated to break through the surface in rough seas.

Significant reduction in exhaust smoke is achieved by incorporating turbo pressure dependent feed forward pitch and load limits with proportional dynamics.

Basic adjustments to limit engine rpm, load and pitch for single or multi engine configurations are easily accomplished using the control head display and soft keys.
