DUAL MUTUAL STANDBY
NOTE: - This feature is available only on DSE7000 Series modules, V2.0.0 and above.
The output controls are failsafe. In the event of a module being out of service (battery removed) the output de-
energises, giving the ok to run signal to the other set.
Screen capture from DSE Configuration Suite PC Software showing the configuration of the Master and Slave controllers.
In case of set 1 failure, the output
activates and energises the
external relay RLY1 to call for the
second set to start. RLY1 contact closes a
battery negative signal onto
the input, instructing the set
to start.
