X + Start Sequence
Start Prepare
(3 start attempts)
Start relay
Stop coil relay
A battery test configured as X + Start sequence, as shown in the above example, will use: Start prepare timer, Start on time and
Start off time. In this example, the genset will crank three times with Start prepare and Start off time delay in between each crank.
When the test has finished, a start failure alarm will be present.
If at any point the battery voltage is lower than the set point Battery test (parameter 6411), the test will be cancelled.
