6.1.4 Double starter
In some emergency installations, the prime mover is equipped with an extra start motor. Dependent on the configuration, the double
starter function can toggle between the two starters or try several attempts with the standard starter before switching to the double
starter.
The function is set up in parameters 6191-6192, and a relay for cranking with the alternative starter is chosen in the I/O setup.
INFO
Remember to write the settings when changing the I/O configuration.
Parameter Name Explanation
6191 Standard attempts Accepted total number of start attempts before a start failure alarm is activated
6192 Double attempts The number of start attempts before redirecting the start signal
The double starter function is enabled by choosing a value higher than zero in channel 6192. This value determines the amount of
attempts on each starter before switching to the next. The standard starter has first priority. When the maximum allowed number of
attempts, defined in channel 6191, is reached, the start attempts stop and the alarm Start failure appears.
• A value of 1 in channel 6192 results in a toggle function with 1 attempt on each starter between toggling.
• A value of 2 in channel 6192 results in a toggle function with 2 attempts on each starter between toggling.
