2.3.
First power-on
For commissioning of the Advanced Power Controller, the
following steps and checks must be carried out:
1.
Connect the line and load cables in accordance with
the wiring diagram and leave the power line fuses
open.
2.
Connect the analog and/or serial/fieldbus communica-
tion signals.
3.
Power the GPC-M module via a 24 Vdc power supply.
4.
Once the GPC-M is switched on, the LEDs start turning
on and off to indicate CPU initialisation. The following
sequence is seen:
a)
All 8 LEDs on steadily at the same time for approx.
2 seconds.
b)
All 8 LEDs flashing simultaneously 3 times for
approx. 2 seconds.
c)
The LEDs light up in sequence from number 1 to
number 8.
5.
Finally, the "RUN" (green) and "ER" (red) LEDs remain
flashing. The "ER" LED will turn off when Digital Input 4
is subsequently connected.
6.
Proceed with programming:
a)
Connect the PC to the GPC-M.
b)
Open the GF_eXpress software and select "IN-
STRUMENTS" and then, in the "Solid State Relay"
drop-down menu, select GPC 40-600A.
c)
After setting the configuration parameters, select
the "SMART CONFIGURATOR" menu.
d)
Complete the indicated steps providing the re-
quired information.
e)
Save the final parameter recipe and send it to the
controller.
f)
Select "WIZARD".
g)
Select "M" and check the following parameters
and their values in the data sheet: OFF/ON = OFF;
MAN/AUTO = MAN, Man.P = 0.0. Change the
parameter if necessary.
7.
Close the power line fuses.
8.
Connect the ENABLE/INTERLOCK signal to Digital In-
put 4. The "ER" LED (red) goes off. If this 24 Vdc signal
is not present, the controller is not enabled to supply
output power to the load and the "ER" LED remains lit.
9.
Change the value of the following parameters with
GF_eXpress: OFF/ON = ON; Man.P = 10.0. With this
action the output is activated at 10% power.
10. If the "ER" (red) LED flashes, the power will not be
delivered. Check for the following possible causes:
•
Fuses not closed.
•
No line voltage.
11. Check:
•
for the GPC 400...600A models, the connection of
the Ref.V_LINE and Ref.V_Load signals (terminals
3/L1 and 4/L2 on connector J6 and, depending on
the options, also check terminals 6/T2 and 5/T1 on
connector J7);
•
for the GPC 40...300A models, the connection of
the Ref.V_LINE and Ref.V_Load signals (terminals
3/L2 and 4/T2 and, depending on the options, also
terminals 5/T3 of connector J10).

12. Test the system by increasing the percentage of power
to the load in small steps (Man.Pparameter) and check-
ing the correct behaviour of the controller using the
monitor functions in GF_eXpress.
