The Woodward LS-522-5/P1 is a brand-new, full-graphic display unit (often called a “facia” or “control panel”) designed to provide a user interface for Woodward’s generator set and engine control systems. The part number 8440-2151 is the specific Woodward drawing or product number for this unit. “REV: A” indicates this is the first revision (Revision A) of this hardware.
Think of it as the “screen and keypad” for a sophisticated generator control system. It allows operators to see what the generator is doing and to input commands.
Key Functions and Features:
-
Human-Machine Interface (HMI):
-
Display: It features a backlit LCD screen (likely a monochrome or basic color display) to show critical information about the generator set’s status.
-
Keypad: It has an integrated keypad (buttons or a membrane-style keypad) that allows operators to navigate menus, view parameters, and control the generator.
-
-
Monitoring and Data Display:
-
The screen provides real-time information such as:
-
Engine Parameters: RPM, coolant temperature, oil pressure, fuel pressure, running hours.
-
Generator Electrical Parameters: Voltage, frequency (Hz), current (amps), power (kW), and power factor.
-
System Status: Whether the unit is off, in auto/ready mode, running, or in a fault/alert state.
-
-
-
Control and Configuration:
-
Operators can use the keypad to perform actions like:
-
Start and Stop the generator.
-
Acknowledge alarms and view fault log history.
-
View setpoints and configuration menus (often with password protection to prevent unauthorized changes).
-
-
It serves as the local interface for an operator standing next to the generator set.
-
-
Integration with a Master Controller:
-
This LS-522 display is not the main computer (like the 2301E-ST from the previous example). Instead, it is a remote operator panel that connects via a communication cable (often a serial link like RS-485) to a primary control module (e.g., a Woodward EasyGen or ProAct series controller).
-
The main controller does all the processing, and this display unit shows the information and sends the user’s button presses back to it.
-
Typical Applications:
This HMI is used as the standard operator interface on a wide range of generator sets controlled by Woodward systems:
-
Standby Generator Sets: For buildings like hospitals, data centers, and office towers.
-
Prime Power Generator Sets: For remote mining, industrial facilities, and construction sites.
-
Marine Generator Sets: For auxiliary power on ships.
Physical Description:
The unit is a panel-mounted module. It is designed to be installed in a generator control panel door or enclosure. It will have a cutout for the screen and keypad on the front and a communication/power connector on the back for wiring to the main controller.
