Issue
Power is on at the Cygnus but the
consumers are not receiving any
power
The system has been switched on
with the Power On/ Off bu on
but there is no display on the RCC
-03
Voltage is lower than 220V over
distance
The indicators on an external
junc on box are flashing
Message on RCC-03: "Ba ery
Voltage Too Low"
The RCD keeps tripping
The MCB keeps tripping
All units in series or parallel con-­‐
nec on do not enable
If the unit shuts down due to low voltage or overload it will restart automa cally when the issue has
been resolved.
Cygnus User Manual - v3.0 2011
Possible Cause(s)
The MCBs or RCDs may not be
switched on
The emergency stop bu on may be
depressed
Voltage drop over long cable
distances
Cygnus is in Load Search mode
This indicates that the voltage has
reached its lower limit in the ba ery
bank
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
Data connec on was unsuccessful

Sugges ons
Check the MCBs and RCDs (Fig.1, B1 & B2) are
pushed up to the on posi on.
Twist the emergency switch clockwise to release.
If the distance between the unit and the consum-­‐
ers is more than 50m the voltage can drop too low.
The voltage can be boosted by following the in-­‐
struc ons in Appendix 1, (6.1.1)
This is normal and is a power saving func on.
When consumers are connected the unit(s) will
automa cally switch out of this mode and the indi-­‐
cators should stay on as long as power is being
used.
Charge Cygnus from your chosen renewable power
source or from an AC grid or secondary power sys-­‐
tems.
Check the electrical integrity of the consumers
being connected to the unit.
Refer to the maximum output ra ng on the unit's
ra ng plate and reduce the total power draw ac-­‐
cordingly.
Turn off the units using the Cygnus 1 RCC-03 (Fig.
1, C2), check the integrity of all connec ons and
that they have been made correctly. A empt to
restart the units.
