6.2.5 Low/High Speed LED
This LED flashes if the alternator speed goes outside the values defined by the Speed Lower
Limit (P02) and Speed Higher Limit (P03) parameters. For a fault to be indicated, the speed must
be outside these limits for longer than the period defined by the Speed Fault Control Delay
parameter P28.
Alternator speed is measured either by measuring alternator output frequency or by monitoring
an external magnetic pick-up, as selected by program parameter P15.
This failure immediately stops the generating set, without any cool-down period.
6.2.6 Alternator Voltage Failure LED
This LED flashes if the alternator output fails to reach the value specified by the Alternator
Voltage Lower Limit parameter P01 within the period defined by the Control On Delay
parameter P26.
This failure immediately stops the generating set, without any cool-down period.
6.2.7 EStP– Emergency Stop
The remote Emergency Stop button has been pressed and has shut down the engine. Press
Reset to remove the indication and restore unit operation.
6.2.8 bAT1 - Low Battery Voltage message
This message appears if, while the engine is running, the battery voltage falls below the value
specified by the Battery voltage lower limit parameter P04. The unit measures battery voltage at
the rear terminals. Depending on the size and length of the cable to the battery, this may be
somewhat less than the voltage as measured at the battery.
6.2.9 bAT2 - Weak Battery Alarm message
This message appears if, during engine cranking, the battery voltage drops below the value
specified by the Battery Voltage Weak Limit parameter P19 for longer than the period specified
by the Battery Voltage Weak Control Time parameter P20. The message is reset by Reset
button.
