Operation principle
C40 controler automatically starts and stops 2 gensets
if SSt input is activated (refer to programming).
Each genset has its own operational timer.
• tF1: partial operational timer (on one cycle, refer to
programming)
• tG1: global operational timer (from last counter reset).
>
Start sequence
From SSt start signal:
• If operational time on source 1 is greater than opera-
tional time on source 2,
-> Start source 1
• If operational time on source 2 is greater than opera-
tional time on source 1,
-> Start source 2
• If next source to start has been selected on HMI,
-> Start the required source.
Rq: In case of “non starting” of priority source, after
1 minute the second source is automatically started.
>
During the sequence
• If partial timer is counted down and sst stil active,
-> The second source is started and the load trans-
ferred
• If active source disappears before the end of the
sequence,
-> The second source is started and remains active
until the end of the partial timer (refer to diagrams 2
& 3)
>
Stop sequence
The cycle is stopped
• either when the state of the input (SSt) changes
• or when a fault appears
• or when the “manual” mode is activated.
