Model Series 600 - Lite Control Panel
From Murcal Municipal
The Series 600 'Lite' Engine Control Panel is a very powerful operator interface for your mechanical or electronic engine. It is applied to pumps with electric motor, VFD, Natural Gas Engine and Diesel drives. The controller plugs directly into your engine and reads all the available data. Additional connections are available for transducers, floats, analog and digital signal devices, and engine shutdown switches. The panel is designed around an MC228 controller featuring easy to use pushbuttons that allow the operator to manually start and throttle the engine. If automatic operation is desired, the unit can also operate in full automatic mode. To conserve power the MC228's LCD backlight can be set to automatically turn off after an adjustable time period.
The S600 'Lite' Panel is housed in a NEMA 4X Hoffman enclosure (14' x 12' x 8') with a transparent front cover that can be clamped shut and locked for safety. The panel features a key switch for Auto-Off-Manual-Crank, a 518PH Tattletale annunciator, a toggle switch for manual throttle control, and a mushroom style E-Stop button located on the right side of the enclosure. This panel also accommodates up to three (3) two-inch (2') Swichgage instruments, allowing you to visually monitor your engine's vital signs: engine oil pressure, engine temperature and manifold vacuum.
Control features include start/stop types configurable for pressure, level, temperature, maintained contact (close to start/open to stop), or via Modbus from a Central controller or PLC. Auto throttling routines include preset RPM, maintained pressure, maintained level, or maximum RPM set point.
The S600 'Lite' sales bulletin features pages showing typical connections made via the three (3) internal terminal blocks. Supplied are dry contacts for engine running and failure, along with one (1) extra contact that can be configured for either a clutch output, exhaust fan output, or a 'go to speed' output (to be connected to a speed-controlled governor).
The controller is MODBUS ready; a list of the holding registers is included in the operation manual. The Compliance Controls AFR64R (MEC-R) Rich-Burn Air-Fuel Ratio Control System makes an excellent addition to the S600 'Lite' Panel for applications requiring emission compliance while maximizing fuel economy.
Engine Speed Control: New electronic engines have multiple options for throttle control. A simple set-point in the MC228 lets you choose from analog, J1939 (future), or digital throttling types. Find out what your engine uses, then select the best type from our menu.
Automatic Speed Control: There are many types of control inputs used for automatic speed control. If you want the engine to maintain a constant speed as the load changes, you will select 'Preset' from our menu. If you want to maintain a maximum RPM, select 'Maximum RPM' from the menu. If you have a pressure transducer on the discharge, select 'Transducer' from our menu and choose the discharge pressure to maintain. A central controller or remote PLC / SCADA system can be used to get the desired speed as well.
Transducer Type: Through simple menu choices and set-point configuration, you can tell the controller the type of transducer you have hooked to the system and calibrate its maximum pressure, level or temperature.
Level Throttle Type: If you are maintaining a level, choose FILL or EMPTY and the controller will automatically alter the way it starts, stop and throttles the engine.
ECU Generated Shutdown Type: As a window into your engine's computer the MC228 will, in most instances, spell out in plain English the reason your onboard computer shut down the engine.
Start/Stop Control: The controller will accept a contact closure, transducer input, or a PLC/Central command for start/stop. The controller is field configurable for single contact closure, pressure transducer, level transducer, PLC/Central controller, or temperature sensor (Model 12).
