XP-COMPACT
V5.5
19/57
The Transfer system is protected against overload with a circuit breaker on the AC
Input side of the XP-COMPACT. If the system has been overloaded, the button/pin of
the fuse will pop out. To put the automatic safety system back in to operating you
must push this pin back.
Note: in the Inverter operation, The XP-COMPACT generates a true sinusoidal and
quartz stabilized output voltage. However if the XP-COMPACT is supplied from a grid
or a generator and the transfer contact is active, then you have at the output AC OUT
the same voltage as that at the input. This voltage can not be modified by the XP-
COMPACT !
4.8.1 Set the transfer voltage threshold
The voltage threshold of the transfer can be adjusted between 150 to 230V with the
turning knobs (23). From factory this value is 200V. Most appliances can work on this
voltage. When the Input voltages reach the selected value on turning knob, the
inverter switches off and the AC INPUT goes directly on the AC OUTPUT. When the
voltage INPUT is less of 20V the value set, the transfer is stopped and the OUTPUT
switches back on the inverter.
Note : Don’t use the turning knobs “TRANSFER” (23) to adjust the AC OUTPUT
voltage ! This is only it’s only a voltage threshold level to enable or disable the
transfer.
4.8.2 FAST (UPS)- MODE for the Transfer Switch
The quick and break free Transfer mode is programmed with a slide switch „Transfer
De-lay“ OFF, which is on the front side (cable connections side).
The aim of the XP-COMPACT is to supply the appliance with a break-free alternating
volt-age. When the incoming voltage AC IN no longer matches values which have
been set with the Turning Knob 23, the inverter switches on at once. The transfer is
carried out in 0.02 seconds. This quick transfer ensures a break-free function for
most appliances. If you have an alternating voltage back at the input AC IN, transfer
system starts up again with-out any break, and the inverter is stopped.
4.8.3 Delayed mode of the Transfer System
The delayed mode of the transfer system „Transfer Delay ON“ is programmed with
the slide switch (D) on front with the cable connections. The XP-COMPACT provides
a break-free alternating voltage for the appliance. A quick transfer switch is not
always sensitive nor is it always desired. For exampleI.E., when the appliances are
operated by a small back-up generator. An overload of a short period 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 desired, the
transfer system can be programmed with a delay. When the slide switch “(Transfer
delay” (D) is in the „On“ position, the transfer to the inverter takes place with a delay
of 5 seconds. If the voltage falls below 100Vac, the transfer takes place without delay
! The transfer switching to the Inverter takes place without any break.
