Flash Before Ready, Fan Cooling And Protection System And Faults - Bowens CREO 1200 Owner's Handbook Manual

flash before ready, fan cooling and protection system and faults

flash before ready
The 'flash before ready' feature makes it possible
to trigger the Creo before recharging has been
completed. If a flash is released before the
generator has recharged to the set power level a
'warbling beep' will be emitted and the channel
LED displays will flash for a short period. This is to
indicate a possible under-exposed frame since the
flash power may not correspond to the set power
level.
fan cooling and protection system
The Creo is equipped with an effective cooling
and protection system that operates to prevent
excessive heat build-up and possible damage.
The system comes into operation when working
at elevated temperatures, at higher flash power
settings and at faster flash rates. Limiting any of
these factors will help keep the internal temperature
of the Creo down.
• FANS - multiple fans are automatically switched
to increase the airflow through the Creo. Always
keep the vents clear of obstructions and away
from external sources of heat.
• CHARGE LIMITER - if the Creo detects a
risk of overheating by use in abnormal operating
conditions, fan failure etc. then the system
will protect the Creo by automatically reducing
the charge rate. The appropriate SPEED LED will
flash to indicate this is in operation. The Creo can
still be used in this mode but it is recommended
that the reason for the increased temperature is
found and removed.
• OVERHEAT - if the charge limiter fails to prevent
the temperature rising then the recharging will
stop completely. This will be indicated by 'OH'
on both 'channel LED displays'. The generator
cannot be used in this state; once the
temperature has decreased sufficiently then
recharging will continue automatically. The
automatic protection should normally only
operate under extreme or fault conditions or
when the air vents are blocked. If an overheat
condition occurs it is recommended the Creo is
left switched 'on' without triggering it to allow the
fans to reduce the temperature accordingly.
fault indications
If a fault develops the Creo will show an error code;
this will override the 'channel LED display'. Error
codes will be displayed as follows:
Channel A Display Channel B Display
E1 01
E1 02
E2 01
E2 02
E2 03
E2 08
E3 01-63
If an error code is displayed it does not necessarily
mean that the unit is faulty but rather a particular
parameter is out of limits. The error may correct
itself once the cause has been removed or if the
Creo is switched to 'standby' and back 'on'. If a
fault persists then the generator should be sent to a
Bowens authorised service centre for analysis.
