Issue
Power is on at the Cygnus HPG but the
consumers are not receiving any power
The system power has been switched on
with one of the mode buttons but there is
no display
There is power being sent to Cygnus HPG
but it is not charging or passing through
power
Output voltage is lower than 220 V AC over
distance
"Battery Voltage Too Low" Message on
RCC-03
The RCD continually trips
The MCB continually trips
Generator auto start not working
A Solar Array is connected to the Solar
Array inputs but the Control Centre's Solar
Charge indicator does not illuminate
Possible Cause(s)
The output MCBs or RCDs may not be
switched on
The emergency switch may be depressed
The input MCBs may not be switched on
If the distance between the unit and the
consumers is more than 50 m the voltage
can drop too low.
This indicates that the battery bank voltage
has reached its lower limit
There is an electrical fault with the
consumers connected to the AC output
The consumers being connected draw too
much power for the rated output of the
unit
Auxiliary signal cable is loose or has been
damaged
The system has not been switched on
The Solar Isolator is in the off position
Suggestion
Check that the MCBs and RCDs are pushed
up to the on position and that the relevant
output LEDs are illuminated.
Twist the emergency switch clockwise to
release.
Check the input MCBs are pushed up to the
on position and the input LEDs are on
Adjust the voltage settings using the RCC
03
Charge Cygnus HPG from your chosen
renewable power source, from an AC grid
connection or secondary power system
Check the electrical integrity of the
consumers being connected to the unit
Refer to the maximum output rating on the
unit's rating plate and reduce the total
power draw accordingly.
Reattach or replace the auxiliary cable.
Ensure that the system is switched on and
that isolators are in the on position.
