Mains
inhibitions to the automatic intervention; the board automatically provides for the closure of
the GCB switch (prior opening of MCB if the temporary parallel is not provided with the
mains). This mode is priority compared to TEST (that is, it can interrupt the recurring test or
replace it). It is also priority compared to AUTO (once the remote starting is activated,
eventual requests of automatic intervention are ignored). The operator cannot changeover
the GCB and MCB switches manually. Accessing programming is allowed, but only some
parameters can be modified.
The operating mode can be selected in three different ways:
Using the buttons
UP
Rif. 1C
and
DOWN
of the board. The buttons must be
pressed continuously for at least half a second to force the mode change. The buttons appear
disabled (on the first line of the display a flashing, key-shaped lighting is shown) if at least
one of the inputs described on the following point exists and is active.
Using one or more configured inputs.
Sending Modbus commands through the serial ports, USB port, the Ethernet port or through
the modems.
To activate the
TEST
mode, it is necessary that the operating mode is set to AUTO and that no requests
of automatic starting are there. The TEST mode is indicated through the AUTO indicator flashing on the
panel (50% on and 50% off). You can shift to TEST mode as follows:
Pressing the START pushbutton from the board panel. Shifting to TEST mode is immediate.
To return to AUTO mode, press again the START pushbutton. If the duration of the test
(P.0420) is configured (different form zero), this test automatically ends after the indicated
time. Parameter P.0222 establishes if the test is void or with load.
By configuring the parameters properly:
▪
P.0418: Test enable days.
▪
P.0419: Test start time.
▪
P.0420: Test duration.
They permit to program weekly time slots during which the generators must run in TEST
mode (to maintain them efficient). In this case, the passage to TEST is automatic in the
scheduled days and hour. The controller returns to AUTO when the TEST time interval ends.
Parameter P.0222 establishes if the test is void or with load.
By means of an SMS. In this case, the controller shifts to TEST as soon as it receives the
SMS and returns to AUTO after the time P.0420 “Duration of starting in test mode (min.)”
Parameter P.0222 establishes if the test is void or with load.
From a PC connected to the serial ports, to the USB port, Ethernet port or via modem (with
RTU Modbus protocol or Modbus/TCP). The board passes to TEST as soon as receives the
command, comes back to AUTO when it receives the opposite command or when it
considers the serial connection lost (60 seconds without messages).

The
GC600
devices can be configured to manage several types of plant and the use modes can vary
consequently
For example, please find below some basic operations of a
SSB+SSTP
plant (Single Stand-By +
Single Short Time Parallel) and a
MPM
plant (Multiple Parallel to Mains).
For eventual details on the others, refer to the Device Technical manuals.
