PFSK152 3BSE018877R1 pulse output card

MW Hours • MW Hours on Generator 

• Increments in 0.1 MWH on System Status screen display.

 • Retained in non-volatile memory, this memory is updated every 4 hours of continuous operation, and every time the engine is stopped. Overspeed 

• Set for overspeed limit of engine.

 • Typically set for 10% above Rated Speed of engine. 

Overspeed Alarm

 • Alarm Set Point. 

• Typically configured to Hard Shutdown for safety. 

• When “Start Sequencing” is Disabled, the PT signal is used to calculate the overspeed signal. No MPU is needed in this condition. 

CAUTION—LOSS OF MPU SIGNAL Woodward recommends that the Speed/Frequency Mismatch Alarm be set the same as the Overspeed Alarm to protect against the loss of the MPU

Battery Volt High Limit 

• Sensed DC voltage supply to EGCP-2. 

• Can be used to detect faulty charging circuit. Battery Voltage Low Limit 

• Used to detect weak battery/failed charger.

 • Automatically Disabled during engine cranking. 

High Oil Pressure 

• Uses Engine mounted pressure sensor. • Active when generator is stable. 

• Display is selectable for psi (American) or Bar (Metric).

Low Oil Pressure Pre-Limit

 • Used to sense failure of lube oil system.

 • Start Sequencing ENABLED, Active at 90% of Rated Speed plus 5 seconds or when Generator Breaker closes plus 5 seconds

 • Start Sequencing DISABLED, Active when Fuel Solenoid output energizes plus 30 seconds or when Generator Breaker closes plus 5 seconds
