10.2 Explanation of settings
Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in
the software configuration programs.
Inverter frequency
Output frequency if no AC is present at the input.
Adjustability: 50 Hz; 60 Hz
Input frequency range
Input frequency range accepted. The product synchronises within this range with the AC input frequency. The output
frequency is then equal to the input frequency.
Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz
Input voltage range
Voltage range accepted. The product synchronises within this range with the AC input. The output voltage is then equal
to the input voltage.
Adjustability:
Lower limit: 180 – 230V
Upper limit: 230 – 270V
Note : the standard lower limit setting of 180V is intended for connection to a weak mains supply, or to a generator with
unstable AC output. This setting may result in a system shut down when connected to a 'brushless, self excited,
externally voltage regulated, synchronous AC generator' (synchronous AVR generator). Most generators rated at 10kVA
or more are synchronous AVR generators. The shut down is initiated when the generator is stopped and revs down while
the AVR simultaneously 'tries' to keep the output voltage of the generator at 230V.
The solution is to increase the lower limit setting to 210VAC (the output of AVR generators is generally very stable), or to
disconnect the product from the generator when a generator stop signal is given (with help of an AC contactor installed in
series with the generator).
Inverter voltage
Output voltage in battery operation.
Adjustability: 210 – 245V
Stand-alone / parallel operation / 2-3 phase setting
Using multiple devices, it is possible to:
•
increase total inverter power (several devices in parallel)
•
create a split-phase system with a separate autotransformer: see VE autotransformer datasheet and manual
•
create a 3-phase system.
The standard product settings are for a single device in stand alone operation.
AES (Automatic Economy Switch)
If this setting is turned 'on', the power consumption in no-load operation and with low loads is decreased by approx. 20%,
by slightly 'narrowing' the sinusoidal voltage. Applicable in stand-alone configuration only.
