5.2 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 (see Section 5.3).
Inverter frequency
Output frequency if no AC is present at the input.
Adjustability: 50Hz; 60Hz
Input frequency range
Input frequency range accepted by the Multi. The Multi synchronises within this range with the
AC input frequency. The output frequency is then equal to the input frequency.
Adjustability: 45 – 65Hz; 45 – 55Hz; 55 – 65Hz
Input voltage range
Voltage range accepted by the Multi. The Multi synchronises within this range with the AC
input voltage. The output voltage is then equal to the input voltage.
Adjustability:
Lower limit: 180 - 230V
Upper limit: 230 - 270V
Inverter voltage
Output voltage of the Multi in battery operation.
Adjustability: 210 – 245V
Search mode
If search mode is 'on', the power consumption in no-load operation is decreased by approx.
70%. In this mode the Multi, when operating in inverter mode, is switched off in case of no
load or very low load, and switches on every two seconds for a short period. If the output
current exceeds a set level, the inverter will continue to operate. If not, the inverter will shut
down again.
Search Mode can be set with a DIP switch.
Search Mode 'shut down' and 'remain on' load levels can be set with VEConfigure.
The standard settings are:
Shut down: 30 Watt (linear load)
Turn on: 60 Watt (linear load)
AES (Automatic Economy Switch)
Instead of the search mode, the AES mode can also be chosen (with help of VEConfigure
only).
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.
Ground relay (see appendix B)
With this relay (H), the neutral conductor of the AC output is grounded to the chassis when the
back feed safety relay is open. This ensures the correct operation of earth leakage circuit
breakers in the output.
If a non-grounded output is required during inverter operation, this function must be turned off.
(Use VE-Configure)
