H.1.1 FAST (UPS)-MODE for the Bypass switch (P-05”DISABLE”)
The quick and almost break free Transfer mode is programmed with the Parameter
P-05 set “DISABLE”.
The aim of the Invertek is to supply the AC loads with a break-free AC voltage.
When the incoming voltage AC IN no longer matches values which have been set
with the “P-06”, the Invertek switches back to Inverter. The transfer is carried out in
0.02 seconds. This quick transfer ensures a break-free function for most AC loads.
If AC voltage is restored at the AC Input which is within the set parameters then the
transfer of power will resume, again with only 0.02 seconds transfer time.
H.1.2 DELAY MODE for the Bypass switch (P-05”ENABLE”)
The delayed mode of the Bypass switch, the Parameter-05 set “ENABLE” and then
the Invertek provides a break-free alternating voltage for the consuming device. A
quick transfer switch is not always sensible nor is it always desired. For example,
when the consuming devices are operated by a small back-up generator. An
overload of a short duration on such a generator, i.e. start of a vacuum cleaner etc.,
has the effect of decreasing the voltage for a short time. As in such cases the
transfer to the Inverter is not desirable, the Bypass switch can be programmed with
a delay. The inverter takes place with a delay of 5 seconds. If the voltage falls
below 100Vac (220V) or 50VAC (110V) the transfer takes place without delay! The
transfer switching to the Inverter takes place without any break.
