test is not carried out). If there is second activation of the input during the test,
the test is immediately stopped. During this test, the controller closes the GCB
circuit breaker, independently from the value configured in P.0222.
o
By properly configuring the parameters:
▪
P.0418
(“Test enable days”).
▪
P.0419
(“Test start time”).
▪
P.0420
(“Test duration”).
They allow selecting the days of the week and a time slot within which the
working mode switches from AUTO to TEST. The controller returns to
AUTO when the TEST time interval ends.
o
By means of a proper command via SMS (refer to document [3]). For this
feature to be used, the parameter P.0420
“Test starting duration” shall not be
set to zero. In this case, the controller shifts from TEST after receiving the
SMS and returns to AUTO after the time P.0420.
o
Through a control from the communication ports, using the Modbus registers
HOLDING REGISTER 101 and 102. These two registers should be written
within 5 seconds one from the other (otherwise the control will not work).
These controls can be enabled by a digital input configured with DIF.2706
function - " Enables the commands by the serial ports": if this input exists, it
should be active.
▪
Write the password configured with P.0004 parameter in the register
101.
▪
Write the following values in the register 102:
•
"12" to switch to TEST (without GCB closure).
•
"14" to switch to TEST (with GCB closure).
•
"21" to return to AUTO.
The TEST control from the communication ports is cancelled if the controller
considers the communication interrupted (60 seconds without a message).
•
REMOTE START: this operation mode differs from AUTO in the fact that the engine
is anyway started (automatically), although the conditions of the system require or not
the automatic intervention of the generator (the "inhibitions to automatic intervention"
are ignored in this mode). If there are no requests for "inhibition to GCB closure",
HS315 will automatically close GCB circuit breaker. The operator cannot manually
control the circuit breakers. When the REMOTE START mode is disabled, the board
returns to AUTO and, if the automatic intervention of the generator is no longer
required, the board opens GCB and stops the engine. Accessing programming is
allowed, though only some parameters can be modified.
To switch to REMOTE START mode, the board should be in AUTO or TEST and there
should be no shutdown and, deactivations. Moreover, it is possible to configure an
input with DIF.2701 function ("Enables remote start requests "): if the input exists, it
should be active.
You can shift to REMOTE START mode as follows:
o
By means of the digital input configured with the feature DIF.2032
(“Request
for REMOTE START mode
”). In this case, it is necessary pay attention to the
delay that is configured for the selected input: the board switches to REMOTE
START when the input is active since the configured time, it comes back to
MAN as soon as the input is deactivated.
o
By properly configuring the parameters:
