SEPHCO LSMC Series Marine Type Load Banks

LSMC type load banks are sea water-cooled resistive load banks designed for on-board installation to monitor and maintain a steady load on diesel generating systems. Designed specifically for marine application such as super motor yachts, the load banks incorporate an integrated control processor management system designed to monitor the vessel’s load condition and supplement the marine generators as the load drops below an acceptable level. Units are supplied as packaged systems or split, supplied complete with circulation pump, and control cabinet ready for installation.

Sizes available in 30KW,40KW,50KW,60KW,75KW

LSMC Series Description

LSMC series load banks are designed for permanent installation on motor yachts and marine vessels to maintain marine generators under load. Featuring the Smartload LSM800D processor, providing accurate load control with incremental load steps to maintain marine generators at a constant set load, eliminating wet stacking and cylinder bore glazing. The control software is designed to load and maintain one or more marine generators, typically a single marine generator operation or when in parallel. The LSM800D controller provides user-friendly field settings, digital display and is available with options to include a remote manual override “Mimic” control panel. .

LSMC load banks incorporate corrosion proof elements, carbon composite vessel construction, copper nickel fittings and plumbing, zinc-free marine bronze pumps and protection from galvanic action and electrolysis. Safety features include monitoring of air locks, water flow, water temperature, element temperature, pump overload and water pressure. Tripping of any of the safety monitoring devices is identified and displayed by the unit controller. Unique features also include circuit breaker protection for each load group and set and forget control parameters.

Installation of LSMC type load banks will ensure optimum reliable power from marine generators. Constant load maintained on marine generators will prevent wet stacking, cylinder bore glazing and reduce emissions.

LSM800MB Automatic Generator Load Controllers

The LSM800MB load bank controller is a monitoring processor which monitors the plant or building load on marine generators. To maintain the marine generator at a desired load set by the controller, loads from the load bank are automatically applied as the building or plant load varies. Loads are applied in discreet values to prevent transient conditions on the marine generator. Fitted with dual menus as an option, the controller expands the monitoring operation to load a two-generator operation.

The controller and load bank is activated only when a voltage-free signal is applied.

All settings such as marine generator capacity, CT value, operating voltage and time delay are field adjustable. Settings remain in memory even during power loss.

Generator Monitoring Input Options

Options of system monitoring inputs are available typically

1. 0-5 Amps (CT) Standard

2. 0-10 VDC (0V=Zero Generator Amps, 10V=Full Generator Amps)

External Command Input

1. External Command Using 0-10VDC (0V=Zero Generator Amps, 10V=Full Generator Amps) Load steps regulated by external PLC.

The monitoring of the load bank’s safety interlocks and fan cooling is still maintained and managed by the LSM800MB controller.

LS800MPE Manual Override “MIMIC” Control Panel

The LS800MPE is an optional control panel added to the load bank installation for remote, manual override of the load bank for periodical testing and exercising of the marine generator. Connection is by a simple three-core cable, connected to the load bank’s auxiliary terminals. Featuring a touch-type keypad and LED display, the LS800MPE offers simple operation for manual controllability of the load bank.

Selection of operation includes Manual Loading, Auto-Loading and Auto Genset Exercise modes. The exercising function is programmable by setting up a load routine with time duration. The LED display indicates the kilowatt value activated at the load bank during any of the switching operations. Additional LED’s display mode selection and the status of the load bank, including fan-cooling fault.

The remote “Enable” signal connected to the LSM800MB prevents operation of the Mimic panel when the generating system is operating in the emergency back-up mode, preventing inadvertent use of the load bank. When the “Enable” signal is closed, the control system reverts back to auto-loading of the marine generator.
