STUDER INNOTEC HP-COMPACT
HP-COMPACT V5.4 26/80
like this the Auxiliary Contact works with the lowest set condition and stops when it
has reached the highest programmed condition through charging.
Example: start of a generator with the HP-COMPACT
In order to program the auxiliary contact to start at 25% and to stop at 75% of the
battery state-of-charge, here is the procedure to follow:
− Press the key AUX. CONTACT (Program) 21 during at least 2 seconds. Then
the states will be displayed blinking (factory settings LED’s 10/11/12/13). As
these states are not wished for the start of the generator, they must be disabled.
− With the key (select) 20, select the LED’s to disable (the active LED’s are
blinking) and disable them with the key 19 Change Status. Select the other
LED’s to switch off with the key (select) 20 and switch them off with the key 19
Change Status until all are disabled.
− Then select the LED 17 with the key (select) 20 and activate the contact with the
key 19 Change Status. The generator will start once the LED 17 switches of.
− Then select the LED 16 with the key (select) 20 and activate the contact with the
key 19 Change Status. The generator will stop once the LED 16 switches on.
− If no key is activated during 30 seconds, the normal operation states are
displayed automatically again.
For a control the key Program can be pressed at least 2 seconds. The values set are
displayed blinking.
As per the inverter output power (not available with some special executions)
Activating the auxiliary contact for the generator start can be programmed also on a
pre-determined output power of the inverter. The auxiliary contact will be activated if
the inverter output power exceeds 80% of the inverter nominal power during 3
minutes and/or 100% during 30 seconds.
The auxiliary contact will remain activated 30 minutes after the input current has
come back to a value lower than the one adjusted by the “INPUT LIMIT” (chap.
4.6.4). In other words, the contact will be deactivated 30 minutes after the lighting out
of the LED 200%.
This programming is achieved accordingly to chap. 5.4.2 of the user manual and by
activating the contact on LED 100% of “Power Monitor” (25).
5.4.4 Power cut of the second priority loads
The auxiliary contact can also be used to cut the power of less priority loads when
the battery state of charge is lower than a given threshold. In that case, only one of
the battery state of charge, or the “transfer” function will be programmed as power cut
criteria.
The second priority loads will be supplied only when the generator is ON or when the
battery has a sufficient threshold.
5.4.5 Manual operating of Auxiliary Contact
The Auxiliary Contact can be operated at any time with the Push Button 21 (AUX.
CONTACT). The LED 6 „Contact manual“ lights up as information that the Contact is
manually operated, and LED 5 „Contact active“ lights up when the Contact is active.
By pushing the Push Button 21 a second time, the Contact is disabled. By pushing it
the third time, automatic functions are restored.
