GC250 Technical Manual 85
To active the
REMOTE START
mode, the board must be in
AUTO
or in
TEST
.
mode.
It is
possible to shift to
REMOTE START
in these cases
:
Configuring a digital input of the
controller to acquire the “Remote start request” with
code DIF.2032. If input is active, the controller passes to
REMOTE START
mode, if it
deactivates, it returns to
AUTO
.
Using parameters P.0426, P.0427 and P.0428 , it is possible to define on a weekly
basis hourly operation intervals when the genset shifts automatically to
REMOTE
START
. In particular, parameter P.0426 allows to set the week days in which this
function is active and the remaining two allow you to set an hour range valid for all
selected days. The range start time (P.0427) refers to the days set in P.0426, while
the range end time (P.0428) refers to the same day, if its value is higher than P.0427,
or to the following day if lower (across midnight). Moreover, setting P.0427 and P.0428
to the same value, you define a full day range.
From a PC connected with a USB port (with protocol Modbus RTU). The controller
shifts to
REMOTE START
after receiving the command from the serial port; it then
reverts to
AUTO
when receiving the opposite command (it remains in
REMOTE START
mode in case the serial connection is interrupted before
receiving the opposite command).
Parameters can be password protected
(P.0004, refer to par. 8.5.1) which has to be sent before every command. To send the
command, it is necessary to write in sequence (within 5 seconds):
▪
HOLDING REGISTER 101: write the password configured with the parameter
P.0004.
▪
HOLDING REGISTER 102: write the value:
▪
“13” to require
REMOTE START
mode.
▪
“21” to go back to
AUTO
.
mode.
9.1.1
Recording of mode in event archive
The controller records any change of the operating mode in the events log, if it is enabled with
bit 0 of the P.0441 parameter:
EVT.1001: records the shift to
OFF/RESET
mode.
EVT.1002: records the shift to
MAN
mode.
EVT.1003: records the shift to
AUTO
mode.
EVT.1004: records the shift to
TEST
mode.
EVT.1005: records the shift to
REMOTE START
mode.
There are some features available for configuring the digital outputs related to the operating
mode:
DOF.3001 -
“Off/reset”. The controller activates this output when in
OFF/RESET
.
mode.
DOF.3002 -
“Man”. The controller activates this output when in
MAN
mode.
DOF.3003 -
“Auto”. The controller activates this output when in
AUTO
mode.
DOF.3004 -
“Test”. The controller activates this output when in
TEST
mode.
DOF.3005 -
“Remote Start”. The controller activates this output when in
REMOTE
START
mode.
DOF.3011 -
“Not in OFF/RESET”. The controller activates this output when it is in
AUTO or
AUTO
o
MAN
mode.
