Specification :

The 704 is an Automatic Mains Failure
module with generator monitoring,
protection and start facilities. It utilises
advanced surface mount construction
techniques to provide a compact yet
highly specified module.
Operation of the module is via three
pushbuttons mounted on the front panel
with STOP, MANUAL and AUTO
positions. Selection of the ‘ Auto’ mode is
confirmed by LED indicator, and monitors
the incoming mains supply ( 3 phase or
single phase) . Should the incoming AC
mains supply fall below a configurable
pre-set limit ( 180V default) , the generator
will be started, and load transferred to the
gen-set.
