Description
Connect the generator phase to this input. The
generator phase voltage upper and lower
limits are programmable.
Neutral terminal for the generator phase.
Neutral terminal for the busbar phase.
Connect the busbar phase to this input. The
busbar voltage upper and lower limits are
programmable.
The positive terminal of the DC Supply shall
be connected to this terminal. The unit
operates on both 12V and 24V battery
systems.
Power supply negative connection.
This input will be driven by a 'normally open'
contact, switching to battery- when active. If
the signal is active, the unit will be allowed to
close the relay output when the voltage level
at the busbar input is below the set limit. See
programming section for more details on
level setting.
This input will be driven by a 'normally open'
contact, switching to battery- when active. If
the signal is active, the unit will be allowed to
close the relay output when the
synchronization conditions are met. Otherwise
it will not close the relay. This input may be
hard wired to battery negative for the fastest
synchronization.
A closed to open transition on this input will
cause the SYNCH RELAY to deenergize.
The synchronization checking may also be
initiated or terminated manually by depressing
the SYNCH pushbutton.
These outputs provide energy to the generator
paralleling contactor. If the genset phase
voltage is not within programmed limits, or if
the genset phase voltage, frequency and
phase angle are not within the programmed
limits compared to the busbar, this relay will
not be energized. If the busbar is not powered
up, synchronization checking may be
overridden with the DEAD BUS ENABLE
input signal.
