GCU-3000 7
SECTION 3 : SYSTEM SETTING & OPERATION
NOTICE
Before proceeding to system setting, you must
install correctly all the wirings connection and
connect the Battery.
3.1 DC Input Power
GCU works with a wide range of battery power inputs
from 9 to 36VDC, and the GCU is protected from any
incorrect DC voltage input and connections.
3.2 System Setting (Programming)
There are 68 lines of programming. You must adjust
each line according to the generator type and
protection requirements.
You can preprogram the GCU-3000 away from the
generator just by using a small power supply.
To enter Line-by-Line programming, first press (OFF)
and then press the (UP Arrow)(Down Arrow) (Pen)
and (MUTE) buttons together for 4 seconds.
The software version appears for 2 seconds, followed
by the word (Prog) for 4 seconds, and then the screen
shows the Line number and value entered for that line
(See illustration below).
(Ln.01) indicates Line.1, and (00) representing the
entered value. You press (UP Arrow) or (Down Arrow)
to change the value. Each time you press the Pen
Button we move to the next Line. If the setting is left
unattended for 30 seconds or if the last Line 68 is
reached the word END indicates that you finished and
all modified values are saved.
To end programming at any time press the (OFF) and
(Pen) Buttons together for 4 seconds until the END
appears.
To restore factory setting at any time press (AUTO)
and (Pen) Buttons together for 4 seconds until the
word (Au.PO) appears.
3.3 The Hour Meter
The (Hour-Meter) is the total accumulation of the
generator operating hours stored in memory. The GCU
never erases or resets the hour meter to zero.
However, to set a new value on the hour-meter
memory, enter programming mode and before the
word (Prog) disappears from the screen (about 4
seconds), press the (OFF) button for 4 seconds, the
panel should now read (Ch.Hr), see the illustration
below. The (0567Hr) displays the current accumulated
operation hour stored in memory.
Now press (UP Arrow) or (Down Arrow) button to
change the hour reading. By holding down the button
you increase the scrolling speed.
To END at any time press the (OFF) and (Pen) Buttons
together for 4 seconds or until the word END appears
on the screen or just leave all keys alone for 10
seconds.
3.4 AC Voltage & Current Setting
The voltage and current reading are set at the factory.
However, when the generator operates in heavy
inductive or capacitive loads, the waveform distortion
causes minor voltage differences.
If you need to correct the voltage or amperage
readings, on the GCU enter System Setting lines (3),
(4), (10), and (11) and increase or decrease the values.
Remember that the high/low voltage and load current
protections utilize these new values for shutdown, and
overload protection, etc.
