mode, and when the input goes back on standby, the controller goes back
to the mode it was in prior to input activation.
•
Using the commands from the communication ports. To use these controls, no input
configured with the functions described in the previous paragraph should be active.
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. To
change the working mode, it is necessary to write (within 5 seconds) the following
Modbus registers in sequence:
o
HOLDING REGISTER 101: enter the password configured with the parameter
P.0004.
o
HOLDING REGISTER 102: "1" to force OFF/RESET, "2" to force MAN, "3" to
force AUTO.
When the main working mode of HS315 is AUTO, it is possible to activate two additional
modes (remember that the board is still in AUTO, then what said above is valid):
•
TEST: 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). With P.0222 parameter ("Enable generator supply on TEST?")
it is possible to indicate to the controller if it should automatically close GCB as a result
the starting of the engine (if the conditions of the system allow the closure of the circuit
breaker). When the TEST mode is disabled, the controller 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 TEST mode, the controller should be in AUTO, there should be no
shutdowns and deactivations, there should be no REMOTE START requests (see
below) and there should be no requests for automatic intervention (see engine
sequence description).
Note: the request for the switching to TEST is lost if the automatic intervention of the
generator is required (for example, if plant battery charge is required): when the
automatic intervention is no longer required, the board will not return to TEST. The
request of the TEST mode from digital input is an exception: when the automatic
intervention is no longer required, if the input is still active, the board will return to
TEST.
You can shift to TEST mode as follows:
o
By simultaneously pressing the START button on the controller panel. The
shift to TEST mode is immediate. Press again these same buttons to return
to AUTO mode. If the test duration (P.0420) is configured (the value must be
different from zero), this stops automatically stops after the indicated time.
o
By using a digital input configured with DIF.2031 function ("Request for TEST
mode e"): the controller switches into TEST when this input is activated and
returns to AUTO when it is deactivated.
o
By using a digital input configured with the function DIF.2029
(“TEST without
load (pulse)
”). The controller evaluates the input activation moment (impulse):
the controller switches to TEST when it activates this input and goes back to
AUTO at the end of the time configured in P.0420 (if P.0420 is set to zero, the
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 doesn’t close
the GCB circuit breaker, independently from the value configured in P.0222.
o
By using a digital input configured with the function DIF.2030
(“TEST with load
(pulse)
”). The controller evaluates the input activation moment (impulse): the
controller switches to TEST when it activates this input and goes back to
AUTO at the end of the time configured in P.0420 (if P.0420 is set to zero, the
