POWER ON
Pressing the toggle switch to ‘POWER ON’ activates the system. The ‘ON’ LED light comes on
if the system is switched on.
NOTE
The control unit mains switch must be set to ON if the remote control is used.
Otherwise it will not function.
INCREASE SPEED
The control unit continuously measures the power output. If the voltage falls by more than 5%
under load or because the generator speed is too slow, with the result that the power output is
no longer sufficient for the current level of consumption, then the control unit increases the
magnetising voltage. Once this reaches the maximum of 14V and the voltage generated is still
below 218V then the ‘ADD RPM’ LED light comes on.
Remedy: – Increase engine speed
– Check belt tension for slippage, tighten or replace belt
OVERLOAD
Under a continuous heavy load the voltage falls to 180V and the current limiter limits the
output current to 17.5 amps. The system can however still continue to be operated without
any problem although the ‘OVERLOAD’ LED will come on.
If there is a sudden heavy load increase the system automatically shuts off and the
‘OVERLOAD’ LED light comes on.
Remedy: Reduce the load, after approx. 20 seconds the system automatically switches itself
back on. It can however also be switched off briefly and then back on again.
HIGH TEMPERATURE Overheating
A continuously high load or an overload can cause the system to overheat. If the system
reaches a temperature of 62 °C the ‘HIGH TEMPERATURE’ LED light starts to flash. At 65 °C
the system automatically shuts off. The system only switches back on automatically once
it has cooled down to 52 °C.
The cause of the overheating can be either incorrect installation, inadequate cooling or a
defective fan.
Remedy: Check that the Control unit is well ventilated. Test the fan operation, if a
suction filter is used the filter may need to be cleaned.
