STUDER INNOTEC HP-COMPACT
HP-COMPACT V5.4 21/80
4.7.1 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.
4.7.2 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 HP-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.
4.7.3 Delayed mode of the Transfer System
The delayed mode of the transfer system „Transfer Delay ON“ is programmed with
the slide switch on front with the cable connections. The HP-COMPACT provides a
break-free alternating voltage for the appliance. A quick transfer switch is not always
sensitive nor is it always desired. For example, 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) 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.
4.8 The Multifunctional Contact In the HP-COMPACT there is a built-in programmable power relay. The potential-free
change-over contact (NO – NC) of this power relay is connected to the screw
terminal AUX CONTACT.
Maximum Contact load: 230Vac / 12Vdc / 24Vdc / 16A !
> 36Vdc / 3A !
With the Push Button 21 „AUXILIARY CONTACT“ the contact can be manually
switched on or off independently from programming and from the operating situation.
The LED 5 “Contact active” shows the status of the contact. The drawing up the
screw terminal “AUX CONTACT” is the inactive position mode, LED 5 “Contact
active” off.
The switching on and off of this contact can be freely programmed for every
operating situation of the HP-COMPACT witch situation is indicated with a LED.
There is no limitation to its application and it is left to your wishes as to where and
how you would like to use it. The example and the setting of this contact are
explained in chapter 5.4.
In factory we program this for a dysfunction alarm. The contact is active when one of
these situations is detected:
